Speed Modes

Regular Speed Mode For: Fine control to perform delicate manoeuvres into hangar and to approach helicopter. This speed mode is dedicated to delicate operations requiring precise and smooth movement. Regular Speed Mode is the default speed setting. Gently push throttle speed button forward, then either accelerate by pushing farther forward or triggering backward movement by pulling on throttle speed button. Always come to a stop before reversing direction.

Figure 2.2.3 Regular Speed Mode

Brisk Speed Mode For: Faster speed to perform prompt manoeuvres in obstacle free environment. Use this mode when in need to cover long distances. To activate Brisk Mode press left hand index finger button and then activate right hand slider switch. The brisk mode will be maintained until the right hand slider switch is released. Once the slider button has been released the Carrier returns to his default regular speed setting. Brisk Mode can only be triggered when Carrier is stopped. It cannot be triggered when Right Hand Slider Switch is already activated. Always come to a stop before reversing direction.

Figure 2.2.4 Brisk Speed Mode

IMPORTANT: Operating the Heli-Carrier may require some initial practice to obtain smooth departures and accelerations. IMPORTANT: The Carrier is programmed with an acceleration ramp and a deceleration ramp to ensure smooth helicopter handling. Remember that when Slider Switch button is released in Regular Speed Mode the traction wheel will continue rolling for approx. 1 feet (30cm) before coming to a stop. When releasing Slider Switch button in Brisk mode the traction wheel will continue rolling for approx 4 feet ( 1.2 meters) before coming to a full stop. Ensure personnel is well aware of this phenomenon.

Controller The electronic controller is located within the control panel. It is connected to a hydraulic distributor block located within the mechanical compartment module. One hand grip sends a signal for lifting/lowering; the other is for forward/backward movement. The electronic control board driver operates according to two computer modes: P1- Regular speed mode, and P3- Brisk speed mode. P1 - Regular speed mode is activated by sliding a thumb button located on the right hand grip. P3 - Brisk speed mode is activated by pulling a trigger with left hand index finger keeping it pressed down while sliding thumb button on right hand grip. For safety purposes this mode can only be triggered when the carrier is stopped. It ensures the operator makes a conscious decision to activate brisk speed mode. It should only be used outdoors. P1 & P3 programs allow the use of a single hydraulic system in two possible modes. P1 is designed to provide a delicate deceleration to a full stop. As the machine has a lower maximum speed in this mode it allows to decelerate in a shorter distance to a full stop. P3 is designed to allow users to reach a higher speed but also requires a longer distance for deceleration to a full stop. This programming has been optimized to allow for best possible speed while ensuring the best deceleration pattern for a swift & smooth helicopter handling. P1 & P3 programs are each divided into three zones. These program zones are called ramps. When triggering one of the thumb slider buttons (either up/down or forward/aft), the carrier enters the first ramp step. This first ramp is required to build-up hydraulic pressure. During the duration of this ramp (1 second), the carrier will not move. While maintaining the selected thumb slider button activated, the program then switches to the second ramp. This ramp is visible as the carrier will start to perform the task required. It can accelerate up to the maximum speed programmed. When the operator releases the thumb slider buttons he triggers the third ramp: the deceleration to a stop of the machine. Note that whenever a slider button is activated the pump will operate for 2 to 3 seconds to prevent solenoid vibration from a tight activation sequence. See Figures 2.2.5 and 2.2.6 below.

Regular Speed Mode 20% ��-------------RAMP--------------�� 40%

Brisk Speed Mode 20% ��-------------RAMP--------------�� 70% When carrier is assembled the manufacturer programs each machine to get the best possible performance. Ten parameters are set-up for P1 and for P3. These parameters define each Ramp. The actual specific parameter set-up for your own machine has been recorded on a chart. This chart has been inserted into the unit's control board cabinet during assembly. It is stored with a spare fuse into the control board cabinet. You should not need to modify this programming as it has been specifically optimized at plant upon manufacturing. Should you ever need to reset the P1 or P3 programs contact the manufacturer for instructions. IMPORTANT: Only experienced mechanics should be allowed to perform such programming adjustments. Beware that minute adjustments can have major impact on carrier performance and can result in unexpected and undesired carrier behavior. Also beware that speed has been optimized during initial programming. This meaning that any attempt to increase speed will be met by a longer distance to a stop and/ or a very sudden stop that could result in undesired helicopter behavior. We strongly recommend that you contact manufacturer prior to attempting any modification to programs. IMPORTANT: Do not submit the controller to water or dust environmental conditions. Make sure controller is protected from excessive shock and vibration. Do not use both grips simultaneously.

Battery Charging: A specific instruction manual for the battery charger is provided following the present manual in this binder. IMPORTANT: Heli-Carriers are supplied with a 115/230 volts battery charger. Upon initiating a first charge, ensure to select appropriate voltage for your territory. Failure to do so can result in serious damage the battery charger. The battery charger receptacle is located on the management panel. Only use charger receptacle for supplied battery charger. Only connect and use the battery charger provided with the Heli-Carrier. To charge batteries carefully insert charger plug into socket located on helicopter carrier management panel. Complete by plugging battery charger to local power supply. Carrier Main Switch may be left in the OFF position during charging process. The carrier can be left unattended while plugged to charger. Automatic battery chargers include delicate electronic components. Ensure your electrical output maintains a steady voltage prior to using your battery charger. High voltage fluctuations can easily result in permanent damage to the charger. We also recommend that you protect the battery charger from damage from daily handling. We recommend that you install the charger permanently on a work bench inside the hangar. This will ensure to prevent knocks and water contact with the charger. Ensure to keep the battery charger in a properly ventilated zone. Batteries: Battery Installation: Remember, Red (+) is positive and Black (-) is negative. Recommended Battery type:

Quantity: 4 (tip: always use 4 batteries of the same brand) ( or 8 batteries is using applicable option)

Type: 12 volts DEEP CYCLE, Also known as: Recreational Vehicle (RV) or Marine type batteries

Tips: Threaded

Acid Format:

Lead Acid in either WET, AGM (absorbed glass matt) or GEL. WET batteries have the advantage of being inexpensive; however they require periodic maintenance to check and adjust acid level. AGM or GEL batteries are more expensive but have the advantage of being sealed and thus maintenance free. These are not considered dangerous material and are readily accepted on commercial transports.

Battery life: The average life of batteries is three (3) years. However, this span varies considerably depending on Carrier and APU use as well as battery age at time of purchase. A sign that batteries are failing is when batteries die immediately or loose charge very rapidly following a full charge process.

/ 38

Battery Charge Management For busy operations, we recommend charging batteries nightly to ensure optimal range available for the next working day. Battery charger can be left unattended during charging process. It monitors battery charge level and will stop when fullest battery reaches its top charge. It will monitor battery charge periodically and trigger again as needed to keep batteries fully charged. In order to extend battery life, we also recommend to only charge when carrier needs it. Batteries have a limited number of times they can successfully be charged in their life time. Each new charging process contributes to reducing battery life span. We thus recommend not plugging the battery charger uselessly when not really needed. The Carrier operates with 4 x 12 volts batteries (or 8 batteries if using applicable option). The Heli-Carrier's electrical system operates on 48volts. The Battery charger only monitors battery charge level of the most charged of the batteries. It ignores batteries that are lesser charged. When batteries are unevenly charged the battery charger will still show battery fully charged because it only monitors the most charged battery. Beware that Carrier performance can be significantly reduced when operating with batteries charged unevenly. Lack of power output in some batteries can result in significantly reduced Carrier range and jerky behavior. In order to prevent such occurrence a converter is used to ensure all batteries are discharged equally when operating the carrier and when using the 12v lighting systems. The converter is a 48v to 12v. model. Beware that if you add accessories on your own and connect them to one of the batteries for 12v output, this will result in an uneven discharge of batteries. We recommend you use additional converters should you add accessories by your own initiative. If your Carrier is equipped with an APU option also remember that your batteries will be discharged unevenly. The APU kit pulls power from the two first batteries for its 24v output. When using the APU remember to charge batteries individually to bring them all back to the same level prior to using the automatic battery charger again. In order to manage the uneven discharge of batteries we recommend that you periodically check battery voltage. To check batteries: measure voltage on each battery with a voltmeter. At full charge you must read approx. 13v. Once you have measured each battery's voltage then compare the values. Gap between batteries should not be more than 0.3 volts. Charge applicable batteries individually to ensure they are brought back within the acceptable range, thus ensuring all four batteries are now charged equally.

2.4 Hydraulic System Introduction The Hydraulic System Diagram is located in Annexes section of this manual. The up/down and forward/aft movements are powered by an hydraulic pump. Once power has been set “On”, motion is then triggered by operating either the Up-Down thumb switch, or the Forward-Backward thumb switch. These components are linked to an electronic controller located inside the control panel on the arm. This controller then sends signals to the hydraulic distributor valve system (control block) located inside the mechanical compartment. This control block is linked to the lift cylinders and the traction wheel motor. At each end of the helicopter carrier main legs, hydraulic cylinders perform the lifting operation. The up/down lifting movement is activated by the switch located on the left hand grip. The lifting system operates slowly to allow the helicopter to delicately position itself against the counterweight arms. The forward/aft movement is activated by the switch located on the right hand grip. It activates the driving motor at the traction wheel. Carrier is operated in regular speed mode by activating only the right hand slider button. The Carrier can be operated in brisk speed mode by activating the index finger button on the left hand grip prior to activating the right hand grip slider button. Oil type and Oil filter The carrier is supplied with standard mineral hydraulic oil with viscosity level of “32" that is readily available worldwide. In extremely cold conditions we recommend switching to winter mineral oil with a viscosity level of "22". The machine can also be used with synthetic oil instead of mineral oil. In this last case we recommend you select one that fits your local yearly temperature peak fluctuations. The carrier requires approx. 20 liters (5 gal) of oil. To confirm that carrier has sufficient oil quantity ensure that you can see the oil at the bottom of the oil filter when opening the cap. Ensure oil level is checked with your Heli-Carrier in low position only. Should oil be added, make sure the Heli-Carrier is still in low position. Failure to do so could result in too much oil in the system and an overflow through the oil reservoir cap. The Oil Filter is also a standard in the industry. It is a 3 mirco-absolute microglass filter (sf-6549). Pressure Gauge An Hydraulic Pressure Gauge is located on the management panel. The oil pressure is measured at the pump. This indicator is used for initial set up of machine at plant and for diagnostics later on when in the field. When in need to perform a diagnostic and get the pressure reading, simply trigger lifting or lowering of machine and read pressure. This pressure reading informs you only of the maximum pressure you are getting with the current pressure set-up. Oil Pressure Adjustment Heli-Carriers are delivered with pressure already adjusted. You should not need to perform any further adjustment. The optimal oil pressure should be the point where the oil pressure is just enough to lift your heaviest helicopter. Any higher pressure above this point results in wasted energy thus resulting in faster battery discharge, lower carrier range and faster component wear. Normal pressure ranges by Carrier model: Pressure for V1020, V1022: between 2000 and 2200 p.s.i. Pressure for V1030, V1032, V1040: between 2500 and 2600 p.s.i. Never attempt to raise pressure above 2900 p.s.i.. Failure to respect this limit can result in damage to pump and lifting cylinders. We recommend that you contact the manufacturer prior to attempting any pressure change toward that limit. In order to adjust pressure you may rotate the screw located on the lower right hand side of the oil distributor block. Appropriate pressure should be in a zone kept at the lowest possible level that will ensure safely lifting your heaviest helicopter. Insufficient pressure results in the helicopter lifting unevenly (one leg may lift higher than the other). Remember that excessive pressure on the other hand results in a significant waste of battery energy and thus results in a shorter carrier range.

/ 38

Legs Lifting Evenly To ensure Carrier legs lift evenly the Heli-Carrier should always be lifted to its upmost position. Doing so ensures that oil is evenly distributed into the system and thus ensures that legs lift to the same height. If the Heli-Carrier is only partially lifted, oil distribution within the system may end up unequal. This can result in the helicopter leaning on one side. Should this event occur, re-cycle the Heli-Carrier multiple times by going as low as possible and reaching the highest level at least five times. This will redistribute oil evenly. Hydraulic Safety Break The carrier is set-up with an hydraulic emergency breaking system designed to ensure the carrier stays in position should power be lost. This lock valve mechanism is designed to prevent the carrier taking uncontrolled speed down a steep slope should power be lost. The system locks the oil flow thus preserving hydraulic status at moment of power failure. Beware that this lock valve will allow a very small quantity of oil to continue passing. This will result in the carrier slowly lowering down to ground and/or slowly roll down a slope. Make sure to turn the traction wheel perpendicular to the slope to block further movement.

/ 38

2.5 Mechanical Features Wheels Recommended tire pressure for pneumatic wheels is indicated in the chart below. For the V1020: Ensure support wheels on Bearings are greased monthly. For the other carrier models the bearings are sealed and do not require maintenance. Figure 2.5.1 Wheel Type, Pressure, Bearings & Bushings

Traction Wheel: All models 16” x 6.5” (40x16 cm) 30-65 psi

Support wheels V1020- 12” x 3.5” (30 x 9 cm) on unsealed bearings 50-80 psi V1022: 12” x 2.5” (30 x 9 cm) on sealed bearings Full Rubber wheel V1030, V1032, V1040: 12” x 3.5” (30 x 9 cm) on sealed bearings Full Rubber wheel

Note 1: If additional traction is desired under challenging conditions, traction tire pressure may be reduced. Note 2: When shipping helicopter carrier by air, tires should be deflated to prevent damage to tubes. Attachment System

Figure 2.5.2 Attachment Arms & Counterweight Arms

Attachment concept: The Heli-Carrier operates with a four point contact system. The helicopter is hooked at its rear wheel pin position with attachment arms and attachment devices (generally hooks). The helicopter is maintained in tail heavy balance with the front counterweight arms. Performing attachment: Roll carrier under helicopter. Rotate attachment arms to come up above skid wheel pins. Then hook attachment device to pins and screw ball to attachment arm. Walk to the counterweight arm and rotate it to have the rubber end come rest on top of skid. Perform same actions on other side of the helicopter. Lift helicopter. Then, as lifting is slowly performed the helicopter takes a tail heavy position. This leads the skids to come rest against the counterweight arms located toward the front of the helicopter. Safety straps can then be used to keep the helicopter in place against these balance arms. See section 3.2 Critical Parameters for more essential information on the best practices for attachment. IMPORTANT: Ensure that the arms are located in mirror positions on left and right side of helicopter in order to maintain a correct distribution of weight. IMPORTANT: Ensure counterweight arms are extended correctly over the skids prior to initiating movement.

3.1 Operating Instructions IMPORTANT: Ensure personnel has been informed of the recommended operating instructions prior to using the carrier. The following instructions are also provided on plastic protected format & yoyo to keep attached to your carrier at all times. A copy of this User Card is also located in the Annexes section at the end of this manual.

Read following instructions prior to using the Heli-Carrier

Start-up

1. Before using carrier verify: Battery charge level is sufficient Oil level is adequate ( oil must be visible in filter when removing cap.) Attachment device is available for helicopter type 2. Unplug battery charger prior to turning Main Switch to “ON” Warning: ***Never operate Carrier while still connected to battery charger. 3. Turn control panel electrical system ON (Press button located on top of control panel). Wait 5 seconds to allow electronic initial start-up. 4. Reach helicopter with carrier 5. Ensure that carrier is at its lowest position 6. Slowly slide Carrier into position under helicopter 7. Lift Carrier 3/4" (20mm) from ground prior to attaching helicopter to carrier (Doing so facilitates ball joint removal at destination)

Set-up 1. Select appropriate attachment device for helicopter type 2. Hook attachments to skids Insert attachment hook in direction that allows vertical screw pin to be located at optimal forward/aft position to ensure moderate helicopter tail heaviness (there should be approx 500lbs of pressure up at the counterweight arms). Relocate pin as necessary on top hook bar. Set-up may need to be readjusted to helicopter weight configuration vs fuel & equipment. 3. Extend attachment arms, insert screw pins into arms & fully screw ball joint into attachment arm Warning: to prevent helicopter from potential fall off ensure that ball joint is screwed in completely into attachment arm and follow with a Double-check of skid pin alignment inside attachment hook cavities to ensure secure hook. 4. Extend counterweight arms place rubber tips over skids Position near strut base. Rotate arm tips onto themselves into the female arm section to obtain appropriate balance for that helicopter. Warning: ***Always use counterweight arms 5. Lift helicopter to maximum height To lift slide thumb switch mounted on left hand grip to “UP” position until top has been reached. Warning: ***Do not operate carrier in partial height position as it may result in one side ending up higher than the other 6. Allow helicopter to take position against counterweight arms. (If needed: Adjust counterweight arms by rotating them in order to obtain the appropriate tail heavy balance) 7. Attach safety straps to hold skids against counterweight arms to prevent rocking

/ 38

Movement 1. Check for obstacles Always keep visual contact with blades & tail. 2. Slowly trigger movement by sliding thumb switch mounted on right hand grip For all initial movements keep slider switch close to neutral position for minimum speed. 3. To operate in “Brisk Speed Mode”

Stop Carrier, then press button located on left hand grip with index finger before sliding thumb switch on right hand grip. Warning: ***Only use “Brisk Speed Mode” in large space and make sure that there are no obstacles in the way. 4. Releasing slider switch stops carrier’s traction Warning: **In Regular Speed Mode Carrier will continue rolling approx. 1 foot (30cm) to full stop. In Brisk Speed Mode Carrier will continue rolling approx. 4 feet (1.2m) to full stop.

Shut Down 1. Remove safety straps before lowering carrier 2. Lower lift to bottom position 3. Turn counterweight arms safely away from skids 4. Unscrew safety ball joint and remove pin from attachment arms 5. Turn attachment arms safely away from skids 6. Remove attachment device from skids 7. If preparing for take-off: Take carrier back to storage zone 8. Turn control panel electrical system OFF (Press button located on top of the control panel) 9. Turn main switch OFF (Select “O” located on management panel). 10. Charge batteries (if applicable)

Safety Instructions Verify Batteries. If going long-distance ensure batteries are fully charged. Set-up attachment device towards the front of the helicopter as much as possible. This maintains the helicopter in a tail heavy position for safety reasons. (For very tail heavy helicopters skip this recommendation). Ensure that ball joint is completely screwed in. If ball joint is not screwed in completely the Helicopter can fall off the carrier. Ensure counterweight arms are fully extended over skids. Failure to extend these counterweight arms can result in serious injuries and/or helicopter damage. Attach blades when going over irregular terrain to prevent them from rocking significantly. Always perform either lifting/lowering OR ground movement. Do not operate both left and right thumb sliding switches at the same time. Have carrier come to a full stop prior to triggering movement in the opposite direction. Failure to do so can result in abrupt helicopter movement against the counterweight arms or the helicopter falling down on its nose.

Always lift helicopter to the highest position from the ground. Lift hydraulic system to maximum height before transporting Helicopter (if not helicopter could end up unbalanced sideways). Before initiating movement ensure helicopter is well balanced on carrier (Tail heavy). This will prevent the helicopter from falling forward when rolling over bumps. Beware of risk especially if helicopter is equipped with a wire strike, as it could puncture carrier’s mechanical compartment. You can adjust balance by relocating attachment device to another wheel pin, relocating attachment pin and/or rotating counterweight arms Meet obstacles at a slight angle to help support wheels drive over them. Keep from meeting obstacles head on as this can result in an abrupt stop to movement. Operate with extreme care on slopes exceeding 3° (5%). Releasing hand grip thumb switch triggers hydraulic braking. Regular Speed Mode Carrier will continue rolling approx. 1 foot (30cm) to stop. Brisk Speed Mode Carrier will continue rolling approx. 4 feet (1.2m) Plan for deceleration distance. Always plan for the 1 to 4 feet (30cm to 1.2m) required for the carrier to stop. Unit needs progressive deceleration to prevent blades from rocking. Never leave helicopter unattended in lifted position. Always lower helicopter to ground position as soon as desired location has been reached. Always turn traction wheel perpendicular to slope when carrier is not in motion. It acts as safety guard against carrier rolling down slope. High Speeds. Only use Brisk Speed Mode in large spaces as it takes approx. 4 feet (1.2m) for the carrier to decelerate and come to a complete stop . Use Regular Speed Mode in slow speed when rolling over bumps such as hangar lip or rails. Beware of rocking blades. Attach blades for such operations. When backing-up beware of obstacles behind operator. When backing into a wall do not stand between control arm and wall. Turn OFF when done with carrier. Turn control panel electrical system OFF (press button located on top of the control panel). Turn main switch OFF (select “O” located on management panel). Never leave carrier and its attachment devices under helicopter during take off or landing. Never leave attachment systems on helicopter for flying operations If using APU beware that batteries discharge quickly and unevenly IMPORTANT: See section 3.5 for additional Safety Requirements.

In the event of the Helitowcart moving in an unexpected way, release hand grip. This action stops tow cart traction in all circumstances.

Although the Helitowcart is designed to be extremely reliable and each unit is rigorously tested after manufacture, the possibility of system malfunction always exist (however small the possibility). Under conditions of system malfunction the operator &/or the controller must (for safety reasons) stop tow cart immediately. Helitowcart accepts no liability for losses of any kind arising from the unexpected stopping of tow cart or arising from improper use of tow cart.

3.2 Critical Attachment Parameters IMPORTANT: Personnel operating the Heli-Carrier should be made fully aware of the Heli-Carrier’s operational concept. The following are essential parameters that need to be understood for safe and efficient use of the device:

Extending Attachment Arms When performing attachment to helicopter, make sure to extend attachment arm sufficiently to allow attachment hook's pin to be in a vertical position. Failure to do so, can impose unbalanced pressure to skid when lifting helicopter as gravity will pull attachment system to a vertical position. It could result in pin unhooking from support bar. See figure 3.2.3.

Figure 3.2.1 Appropriate Attachment Arm Extension

Correct Wrong

When performing attachment to MD500, make sure Attachment Arm is extended beyond skid when attaching pin as for this helicopter type, skids tend to extend outward when lifting helicopter from ground. By installing the pin in a inward slanted position, it will become straight when lifting helicopter. Failure to do so can impose unbalanced pressure to skid and result in attachment system unhooking from support bar. See figure 3.2.4.

Figure 3.2.2 Appropriate Arm Extension for MD500

Wrong Correct

/ 38

Using Attachment Hooks Always use proprer attachment hook model for your helicopter type: Figure 3.2.3

AS350 B206B B206L EC120 EC130 EC145 MD500 Univ (EC135)

Same for B407, B205, B212, B214B,B412

Attachment hooks consist of four zones zones: Firgure 3.2.4

Attachment hooks: Properly inserting the attachment brackets to skid pins/skid holes is essential to helicopter safety. Where attachment hooks attach to skid pins, ensure that the bracket is correctly positioned prior to lifting the helicopter. Failure to correctly align bracket to pins can result in the helicopter falling off carrier while handling. We recommend that the operator visually double-check each bracket position prior to triggering helicopter lift as an attachment hook shift may have occurred while screwing the ball joint. Screw Pin: In order to obtain the correct tail heaviness balance for each helicopter's configuration, it is necessary to position the Screw Pin in the correct hole located on the Screw Pin Position Bar. Moving the Pin forward/aft on this Position Bar has significant effect on helicopter tail heaviness ratio. Normally the pin should be adjusted to each specific helicopter at first use and should not need to be relocated unless a significant change to weight & balance is present.. See section 3.3 Critical Initial Set-Up for Each Helicopter. Ball Joint: It is essential to always fully screw ball joint against support bar. Failure to do so can result in the helicopter slipping out of the attachment hook during operations. This can result in serious damage to helicopter. See figure 3.2.5. Tip: For operators who find it hard to release this ball joint at destination if terrain is different than at helicopter pick up, we recommend to lift carrier 3/4" (20mm) off ground before screwing ball joint fully into support arm. This provides manoeuver to easily unscrew ball joint at destination while still ensuring tightly attached helicopter during transport.

Figure 3.2.5. – Securing Attachment Hook Ball Joint

Attachment hook direction: We recommend that attachment hooks be inserted into skid pins with openings facing helicopter tail. The screw pin should then be positioned to provide correct balance. However, in some circumstances where the helicopter is exceptionally nose or tail heavy it might be appropriate to insert the bracket with the openings facing helicopter nose thus allowing the screw pin to be positionned correctly for this particular helicopter. See figures 3.2.6 and 3.2.7 Figure 3.2.6. – Attachment Hook Openings

Figure 3.2.7. – Attachment Hook Direction

NOTE for operators of very tail heavy helicopters such as helicopter ambulance EC145: Such helicopter may require that tail heaviness be reduced rather than increased. In such case it may be more practical to insert the attachment hook the other way around (with pin opennings toward helicopter nose).

D) Hook applicable attachment system to helicopter skid, E) Slide carrier attachment arm out and secure by fully screwing Ball Joint into extendable arm, F) Rotate & extend counterweight arm to position rubber tip over skid close to vertical strut base, G) Lift helicopter to top height, H) Attach safety strap around skid and counterweight arm to prevent rocking. See figure 3.2.8

Figure 3.2.8 - Safety Strap

3.3 Critical Initial Set-up for Each Helicopter

IMPORTANT: Upon using the Heli-Carrier for the first time with a specific helicopter it is important to take the time to perform the necessary adjustment and identify the best component set-up to obtain the safest and most efficient helicopter behaviour when operating carrier. Ensure personnel has a thorough understanding of the following.

Optimizing Helicopter Balance: IMPORTANT The Heli-Carrier is designed to hook to the helicopter’s own wheel attachment pins which are located close to its center of gravity. The Carrier concept works as follows: As the helicopter is lifted from this point it is meant to rock backward on its tail. This is when the front part of helicopter skids come to rest against the counterweight arms that have been extended and positioned appropriately prior to lifting. The objective is to ensure the helicopter nose is slightly higher than the tail to prevent it from falling back on its nose and thus stay in a tail heavy balance. In order for the Heli-Carrier to provide a smooth ride for the helicopter, we recommend that the helicopter be maintained in this light tail-heavy balance. A correct balance is when a medium built individual can stand on the skid at front and the helicopter still maintains a resting position against the counterweight arms in a tail-heavy balance. As well, an indicator of appropriate balance adjustment is reached when the helicopter rotates back smoothly to reach and rest against the counterweight arms as it is lifted from ground. If the helicopter is set to a position that is too nose heavy its nose will fall back to the ground at the first bump or brisk stop. If the helicopter is set to a position that is too tail heavy then the helicopter will go rest against the counterweight arms in an abrupt and rough movement when lifting and can then damage the counterweight arm tips by bending them upward. Optimal balance parameters have to be identified for each helicopter. This ideal balance point may be different for each helicopter depending on how the helicopter is loaded with fuel and luggage at each use. Accessories, fuel and luggage distribution within the helicopter have significant impact on helicopter behavior. An initial identification of the helicopter balance in its most frequent weight distribution configuration should be performed with the carrier; meaning finding the carrier's best general configuration. From that set-up, minor adjustments may then be needed for out of ordinary fuel and bagage distribution as they occur in the course of regular operations. When first using the Heli-Carrier with a helicopter some adjustment may be necessary to figure out the best balance configuration for that helicopter. Find next page the 3 recommended steps to help you reach the best balance adjustment for your helicopter: IMPORTANT: Ensure Right & Left Carrier sides weight distribution are set-up identically to prevent helicopter loosing balance sideways during operations. Also always lift Carrier to top position to ensure carrier legs do not end up at uneven heights while carrying helicopter.

/ 38

Step 1) Hook Attachment to Most Forward Position Always set-up attachment device as much as possible toward helicopter nose as this keeps the helicopter in a stronger tail heavy position and maintains it in place better when going over bumps, abruptly stopping or going nose down a steep slope. First: set Attachment hook to the most forward position on the skid wheel pins (if applicable). The same principle applies to the use of the AT1000-UNIV (EC135) Clamp attachment system: Slide attachment forward for a better tail heavy position. For operators of very tail heavy helicopters such as EC145 ambulances the tail heaviness be need to be reduced rather than increased. In such case it may be more practical to insert the attachment hook as aft as possible and with opennings forward to achieve the best balance. Figure 3.3.1. – Forward Hooking Position

Step 2) Adjust Screw Pin Position In order to adjust balance, the vertical pin on the attachment hook can be relocated forward or aft. Figure 3.3.2 – Screw Pin Positionning

Step 3) Rotate Counterweight Arms Extendable sections of the counterweight arms have their rubber tip section welded in an off-center position. This is to allow you to rotate this arm section to again help you refine your helicopter balance. Figure 3.2.10. – Counterweight Arm Rotation

3.4 Optimizing Traction IMPORTANT: When using the Heli-Carrier in icy winter conditions or on other challenging surfaces you may need to increase traction. Ensure your personnel is made aware of the following instructions to allow them to benefit from a quick and easy way to improve Carrier performance. Optimizing Traction: In weather conditions that require optimal traction, we recommend that the Attachment Arms be rotated toward the traction wheel. This shifts the helicopter weight toward the traction wheel and thus results in greater traction capability. . See figure 3.4.1 Note: If you have accessories installed under the helicopter nose, ensure you maintain sufficient distance to cabinet motor and accessory basket to prevent applicable damage should the helicopter fall on its nose on rugged terrain. Figure 3.4.1 – Weight Transfer Diagram

More tips on optimizing traction in winter conditions: Climb steep slopes at an angle. Slightly deflate traction wheel tire. When a support wheel is stuck in ice, turn traction wheel sideways and activate carrier (in a zig-zag pattern).

3.5 Safety Requirements

Safety Requirements

Read following recommendations prior to using the Heli-Carrier

Before using the Heli-Carrier

• Ensure batteries are sufficiently charged

• Ensure battery charger has been disconnected

• Ensure battery charger is unplugged from power source prior to disconnecting it from Heli-Carrier

• Ensure tire pressure is appropriate

• Ensure nothing interferes with wheels

• Ensure position of hand grip control panel enables you to carry out all functions comfortably

Operating the Heli-Carrier in a safe environment

• Use extra caution when operating on slippery surfaces (snow, ice, etc)

• Do not use under extreme climatic conditions (storm, rain, etc)

• Approach slopes exceeding 3° (5%) with extreme care (climb crosswise to prevent helicopter nose from falling down off counterweight arms)

• Always turn traction wheel 90 degrees when stopping on a slope to lock carrier traction wheel

• Do not store your Heli-Carrier in any place without surveillance

• Do not leave your Heli-Carrier under the rain

• Do not store your Heli-Carrier in a wet or salty environment as it could cause dangerous defects

• Do not use your battery charger in a hermetic environment & avoid shocks

• Avoid any shock to hand grip control panel

• If you move outside at night, ensure that you will be well seen by others

• Do not use your Heli-Carrier when you are on surfaces or in places where a loss of traction can prove dangerous.

Ensuring Personnel safety

• Do not attempt to operate the Heli-Carrier while standing on it

• Do not transport passengers

• Do not stand between the Heli-Carrier’s legs

• Do not use on streets

• Never leave Heli-Carrier with its main switch ON for extended periods of time or within reach of untrained individuals.

• Beware of electrical shocks: This carrier is a source of high voltage. Only experienced personnel should be authorized to take-off motor cabinet cover for access to electrical components

• Do not use your Heli-Carrier if you know that the controller, the hand grip control panel or any other part of your Heli-Carrier control system needs repair.

Using Transmitters and receivers

• Avoid proximity to sources of electromagnetic emissions.

• Always put carrier Main switch in the OFF position prior to using a cellular phone or a CB device.

• Always put carrier Main switch in the OFF position as soon as an erratic operation of the Helitowcart appears. Should any such incident occur, please inform Vanair inc. makers of the Helitowcart.

Setting the helicopter on the Heli-Carrier

• When sliding Heli-Carrier under helicopter as well as when lifting: Always ensure that helicopter carrier clears aircraft bottom and accessories to prevent damage.

• Always keep visual contact with helicopter carrier when setting up carrier under the helicopter. This is to avoid damage to the helicopter or its attached equipment.

• Position attachment arms and counterweight arms at mirror positions on each side of the helicopter to make sure the helicopter is maintained in correct balance during operations.

• Always lift helicopter to top position in order to maintain optimal oil pressure and thus helicopter balance on carrier legs. This is to prevent helicopter from leaning sideways as oil may switch to the leg side where the helicopter has a lighter weight.

/ 38

• Use safety straps to keep skids from rocking against the counterweight arms

• Always deposit helicopter back to ground and remove attachment device components immediately after completing helicopter movement.

• Never leave Heli-Carrier unattended with attachment system set-up and lift in the up position.

• Under no circumstances the helicopter should be lifted and moved horizontally at the same time.

Initiating Heli-Carrier movement

Acceleration / Deceleration

• Do not change direction & speed at the same time or abruptly. Always perform one before the other. Always perform either lifting/lowering OR ground movement. Do not operate both hand grips at the same time. When activating hand grip, never cross from one direction to the other (Forward/Backward) without first stopping all helicopter movement.

• Reduce your speed in restricted or encumbered places

• Beware: Slight adjustments can make significant acceleration/deceleration.

• For initial movement keep hand grip switch close to neutral position for minimum speed.

• Ensure slow, delicate and progressive hand grip switch movement at all times.

• Activate speed selector gently when triggering movement in order to avoid unexpected helicopter rocking movement against counterweight arms. Use safety straps.

• The Heli-Carrier requires a certain distance to allow deceleration to a complete stop. Ensure sufficient space is allowed for deceleration process in order to prevent helicopter. This is applicable even when action button is suddenly released.

Obstacles

• Ensure there are no obstacles near the tail especially when performing turns as small radius at the control bar can have substantial rotation effect at the tail.

• Always make sure that there is sufficient maneuvering clearance in all directions when operating device. Slopes

• Do not operate Heli-Carrier down a slope without safety straps holding the front skids to the counterweight arms. Approach slopes & hangar rails in diagonal for better unit performance

Flight Operations

• Never leave attachment devices on the helicopter for flying operations.

• Never leave carrier and its attachment devices under the helicopter during take-off or landing.

• Never leave carrier and its attachment devices within helicopter path during take-off or landing. Handling Operations

5.0 Breakdown Service Guide IMPORTANT: If this breakdown service guide does not meet your needs or if your problem persists, contact an Helitowcart representative. We invite you to contact us at the telephone number and/or email address indicated on the cover of this binder. Rest assured that we take at heart your concerns and will ensure we provide you with all applicable guidance to solve your issue.

If Helicopter carrier does not respond to Up-Down or Forward-Aft hand grip switch movement (i.e. pump does not start), then:

a) Check that Heli-Carrier main switch it ON (in position “1”) b) Check that the Control Panel On/Off switch is ON and stays locked in that position. c) Check fuse on control panel d) Check switch output to pump solenoid ( see wiring diagram) e) Check pump solenoid f) Check pump motor

If pump starts but there is no movement after one second, then:

a) Check solenoid up-down valve (red led indicates all system up to that point is ok) b) Check connector on solenoid up-down valve

If Heli-Carrier legs do not lift to equal height, or one leg side is down, then: If situation occurs without helicopter: recycle up/down 5 times to readjust oil distribution & eliminaite air in syst. If situation occurs with helicopter: Hydraulic system pressure is too low. Increase hydraulic pressure.

If Heli-Carrier jerks or acts erratically to hand grip movement: a) Air may be logged in the hydraulic system. To bleed air: Put traction wheel on block. Unscrew the proportional valve (ie the one with the black solenoid on top of the manifold distribution block). Operate hand grip in forward and backward motion. You should see bubble forming on top of proportional valve. When air has been purged continue operating the forward/backward motion while screwing the proportional valve shut. b) Check voltage and connection to batteries (very low batteries can be problem source) (If voltage is too low the electronic components may start working erratically

If Heli-carrier is making a clicking sound at the traction wheel motor: This situation is normal. Under normal operation a Gerolor motor produces a rattle that is audible. This is caused by the movement of the Gerolor in its housing. These two metallic parts normally touch when rotating and thus produce this noise. This contact between the two parts allows pressure to build up and creates the force that keeps the motor running.

If Heli-carrier has failed in up position loaded with helicopter: See following pages for instructions on how to lower helicopter to ground and how to tow machine back to base.

/ 38

If Carrier fails with helicopter in up position. How to LOWER Carrier down to ground:

Carrier Configuration 1:

Step 1:

• Turn all electrical systems off

• Get emergency hose located on battery holder screw.

Step 2:

• Unscrew drain plug cap located on distributor block.

Step 3:

• Insert small tip of emergency hose into oil tank

Step 4:

• Screw hose adapter tightly to valve.This will open valve and allow oil to flow toward oil tank. (Process is slow: this is normal)

Step 5:

• When bottom position is reached put cap back on valve

Step 6:

• Secure emergency hose back to battery holder screw

/ 38

Carrier Configuration 2:

1) Locate Valve

2) Unlock valve with 1/2" (13mm) key.

3) Release Pressure. Use Allen Key 5/32" (No 4 metric). Turn Clockwise approx. 2 full turns. Heli comes down. 4) Perform all above actions in reverse to re-activate system once helicopter has been put down.

/ 38

If Carrier fails far from hangar. How to EMERGENCY TOW Carrier back to base: How to prepare hydraulic system prior to towing the Carrier:

Step 1:

• Turn all electrical systems off Step 2:

• Unlock Allen Key with 3/4" wrench key

• Use Allen Key (3/16") to release valve located on hydraulic block located on management panel. This will allow oil to recycle through system during towing.

• IMPORTANT: Do not tow machine at more than 8 km/h. Towing above this speed could severely damage hydraulic system.

How to use Emergency Tow Bar option:

Step 3: If you have an emergency tow bar:

• Lift Tow Bar from Support.

• Insert Tow Bar tip into support.

• Insert Pin,

• Tow. ***IMPORTANT: Never exceed 8km/h while towing Carrier.
