¡Do not turn the undercarriage with the frontof the machine body lifted using the hoeattachment and the upperstructure left inthis posture. Doing so will twist the crawlerwith the load concentrated on a singlepoint on the crawler belt, rapidly leadingto damage.

¡Avoid changing course abruptly andspinning on concrete surfaces wheneverpossible.Doing so may wear or damage the rubbercrawlers.

¡Avoid drops that may expose the rubbercrawlers to strong shocks.

¡Salt, potassium chloride, ammoniumsulfate, potassium sulfate, and triplesuperphosphate of lime can damage thecrawler belts. If any of these substancesshould get on the crawler belts, wash themoff thoroughly with water.

¡Do not let the sides of the rubber crawlersrub against concrete or walls.

¡Do not damage the rubber crawlers byhitting the bucket against them.

¡Be especially careful in the winter onsnowy or frozen surfaces as the crawlerbelts tend to slip.

¡Use rubber crawler belts at temperaturesbetween -25°C to +55°C (-14°F to 131°F).

L4D013

¡When storing the rubber crawlers for longperiods of time (3 months or more), do soindoors in a place not exposed to directsunlight or rain.

¡Rubber crawler belts are not as stable assteel crawler belts since the entire lug isrubber. Be very careful when slewing andswinging sideways.

Preventing the Rubber Crawlers fromSlipping OffHeed the following in order to prevent therubber crawlers from slipping off:¡Always keep the crawlers at the proper

tension.

¡When traveling up large cobblestone orrock steps (20 cm(8 in.) or greater), climbup the step at a direct angle and do notchange course on top of the step.

86

OPERATION


¡Do not change directions when the crawlerbelts are slack as shown in the diagram.

¡When climbing in reverse, do not changecourse at the point where the slope starts.

¡Avoid traveling with one crawler on a slopeor projecting object and the other crawleron a flat surface (with the machine at a tiltof 10° or greater). Travel with bothcrawlers on flat surfaces.

SPECIFICATIONS

Rated lift capacity chart¡The loads in the charts do not exceed 87% of hydraulic lift capacity or 75% of tipping load.¡Rated lift capacities limited by rated hydraulic lift capacity are identified by an asterisk(*)¡The mass of slings and any auxiliary lifting devices shall be deducted from the rated load

to determine the net load that may be lifted.¡The load point is the bucket hinge pin, and the bucket posture is with the standard bucket

completely retracted under the arm.¡Units: kg (lbs.) or daN (lbs.)

Load hooking systemA load hooking system with all of the following capacities must be provided and used.1. A system which can withstand a weight of two times the rated lift capacity no matter at

what position the load is applied.2. A system in which there is no risk of the lifted load falling from the hooking device, for

example one equipped with a hook slippage prevention device.3. A system in which there is no risk of the hooking system slipping from the hoe attachment.

WARNING

¡¡¡¡¡DO NOT attempt to lift or hold any load that is greater than these rated values attheir specified load radii and height.

¡¡¡¡¡All rated lift capacities are based on the machine being level and on a firm supportingsurface. For safe working loads, the user is expected to make due allowance for theparticular job conditions such as soft or uneven ground, non-level condition, sideloads, hazardous conditions, experience of personnel, etc. The operator and otherpersonnel should fully acquaint themselves with the operator’s manual furnishedby the manufacturer before operating this machine, and rules for safe operation ofequipment shall be adhered to at all times.

Precautions on Safety

WARNING

Heed the following when removing or installing an attachment or option:¡¡¡¡¡Consult with a Takeuchi dealer before installing optional attachments.¡¡¡¡¡Do not use attachments that have not been approved by Takeuchi or a Takeuchi

dealer. Doing so may compromise safety or adversely affect the machine’s operationor service life.

¡¡¡¡¡Takeuchi will not be held responsible for any injuries, accidents or damage toproducts caused by the use of a non-approved attachment.

¡¡¡¡¡Choose a flat, hard surface to perform the operations. Also make sure there is enoughlight and good ventilation.

¡¡¡¡¡Clean the area, remove any articles that may get in the way or be dangerous, andremove any spilt oil or grease.

¡¡¡¡¡When performing lifting operations, determine a person to lead the operations andalways follow that person’s instructions.• Follow the leader’s instructions on operating methods and procedures.• Determine a signal leader and heed this person’s signals.

¡¡¡¡¡When removing or installing the hoe attachment, place it in a stable position so thatit does not tip over.

¡¡¡¡¡Due to the risk of loads falling and/or hitting people, do not allow unauthorizedpersonnel in the work area.

¡¡¡¡¡Use the crane to carry heavy objects (25 kg (55 lb.) or greater).¡¡¡¡¡When removing heavy parts, be sure to prop them up before removing them. When

lifting them with a crane, be careful to balance them properly.¡¡¡¡¡Operating with loads suspended with the crane is dangerous. Place loads on a

stand and check for safety.¡¡¡¡¡When attaching the boom or arm, failure to follow proper procedures could result in

serious damage. Consult with a Takeuchi dealer beforehand.

Precautions on Installing Attachments

After replacing optional attachments or other special attachments, test-run them, then inspectthe hydraulic oil level and add oil if necessary.In addition, consult with a Takeuchi dealer for details of removal and installation procedures.

General Precautions

Precautions on Operating Attachments

WARNING

Long attachments reduce machine stability. When traveling down steep slopes orslewing on slopes, the machine may loose its balance and tip over.The following operations are particularly dangerous. Do not perform them.

¡¡¡¡¡When heavy attachments are installed, the overslew (the distance from where theoperation to stop slewing is performed until slewing stops completely) increasesand mistakes in judgment may result in the attachment hitting surrounding objects.Allow for plenty of room between the attachment and obstacles.In addition, the natural drop (the gradual dropping of the attachment under its ownweight when it is stopped in midair) also increases when heavy attachments areinstalled.

¡¡¡¡¡The machine can tip over more easily in the lateral direction than in the longitudinaldirection.• Do not slew (swing) sideways with excessive weight at the front. In particular do

not slew sideways on slopes.• The front is heavier for machines equipped with breakers, crushers or telescopic

arms than for machines equipped with the standard bucket. Do not operate suchmachines sideways, especially with the digging arm (boom) downhill.

¡¡¡¡¡When a long arm or a telescopic arm is installed, the operating range suddenlyincreases and mistakes in judgment may result in the attachment hitting surroundingobjects. Allow for plenty of room between the attachment and obstacles.

¡¡¡¡¡Traveling down slopeswith the attachment lifted

¡¡¡¡¡Traveling across slopes ¡¡¡¡¡Slewing on slopes

Biodegradable Oil

Biodegradable oil

Biodegradable oil is a new type of hydraulic oil that is decomposed into carbon dioxide andwater by microorganisms in the soil and water. It is highly safe for living organisms and offersadvantages in terms of environmental protection.¡Recommended biodegradable oil: Mobile EAL Envirosyn 46H (an ester synthetic oil).

When replacing the hydraulic oil with biodegradable oil, use the above or an equivalent oil.Note that other oils, even other brands of ester synthetic oils, may damage O-rings, packingsand seals. Takeuchi products shipped with the optional biodegradable oil are shipped withthe above brand of oil.

¡When switching from a mineral oil to a biodegradable oil, the parking brake torque decreasesby about 30%.

Replacing the hydraulic oil with biodegradable oil

Mixing mineral oil with biodegradable oil will result in a decrease of the hydraulic oil’sperformance as well as a decrease in biodegradability and safety. The hydraulic oil systemmust be flushed as described below before supplying the biodegradable oil. This operationis dangerous and requires experience. Have it performed by a Takeuchi sales or serviceoutlet.

Flushing¡To be performed by a Takeuchi sales or service outlet1. Drain the hydraulic oil (mineral oil) from the hydraulic tank and clean the inside of the tank

and suction strainer.Refer to page 123 “Replacing the Hydraulic Oil and Cleaning the Suction Strainer”.

2. Remove the cylinder hoses and drain the hydraulic oil (mineral oil) from inside the cylinders.3. Supply new biodegradable oil to the hydraulic tank.4. Bleed the air from the pump and cylinders and pressurize the hydraulic tank.5. Operate the hydraulic devices for 30 minutes.6. Drain the biodegradable oil from the tank and cylinders.7. Replace the hydraulic oil return filter with a new filter.8. Repeat steps 3 and 4.9. Operate the hydraulic devices for 30 minutes.10. Drain the biodegradable oil from the tank and cylinders.11. Repeat steps 3 and 4.12. Operate the hydraulic devices for 1 hour.13. Drain the biodegradable oil from the tank and cylinders.14. Replace the return filter with a new filter.15. Repeat steps 3 and 4.16. Operate the hydraulic devices, then check for oil leakage.¡There is no need to flush the hydraulic oil system when switching from biodegradable to

mineral hydraulic oil.

Air Conditioner (TB135 / TB145)

CAUTIONS ON USE

Ventilate periodically

¡When using the air conditioner over anextended period of time, open thewindows about once each hour to let infresh air.

¡Your eyes may become irritated if yousmoke while using the air conditioner. Ifthis happens, open the windows to let infresh air. Cigarette smoke particularlyirritates the eyes when using the airconditioner because the humidity in thecabin drops and the eyes’ membranestend to become dry.

Always maintain good visibility

Working with the windows dirty or foggedrestricts visibility and is dangerous. Alwaysclean dirt and moisture off the windowsbefore working.¡The windows tends to get foggy when the

humidity is high. If this happens, turn onthe air conditioner and use outside air andthe defroster to get rid of the fog.

¡ If the air conditioner is set to high whenusing the defroster, the difference betweenthe external and internal temperaturesincreases, and fog may form on theoutside of the windows. If this happens,either turn the air conditioner off or turnthe temperature control dial clockwise toincrease the internal temperature.

¡Mist may blow out of the air outlets. Thisis not a malfunction. When moist airpasses through the air conditioner unit’sevaporator, water particles in the air freezeand are emitted as mist.

Do not overcool

For health purposes, the air inside the cabshould be kept at a temperature at which youfeel a little cool when entering the cab fromoutside (a difference of 5 to 6°C (9 to 11°F)).Be careful to adjust the temperature properly.

Do not turn the air conditioner onuntil the engine is started

To avoid placing an excessive load on thecompressor, wait until the engine is startedand is running smoothly before turning onthe air conditioner.

Let hot air out first

If the excavator has been parked in the sun,open the windows or door to let the hot airout of the cab before using the air conditioner.

Caution on refrigerant (gas)

Exposure of the eyes or hands to the cooler’srefrigerant could result in blindness orfrostbite. Never touch the refrigerant orloosen the parts of the cooling circuit.Should the refrigerant gas leak, keep flamesaway.
