The manufacturer does not furnishtractors with fire extinguishers.
HEALTH AND LIVINGENVIRONMENT PROTECTION
48. Tractors are not furnished withspecial filters for cleaning the air suckedto the tractor cab. Therefore they are not
designed for working with aerosols andother harmful substances.49. Kerosene, gas oils, mineral oils andother crude oil products, which are usedfor tractor operation and servicing, cancause different skin diseases in the caseof direct contact, they have irritatingeffects on the mucous membrane, eyes,digestive apparatus, and upperrespiratory ways. Some of them – whenswallowed – can cause even generalintoxication.50. The operators who enter in contactwith oil products are obliged to attain tosafety and hygienic instructionsconsequently, make use of appropriateprotecting means, and work in well-ventilated rooms.
MANIPULATION OF CRUDE-OIL PRODUCTS
51. After concluding the work, washyourself with a non-irritant agent andtreat your hands with a suitable skinointment or cream.52. When connecting and disconnectingthe hydraulic circuit quick couplers,remove – with a piece of any cloth – theresidual oil, which remains in the couplersocket or plug.

Pump type Oil amount supplied1. UC 20 55 l/min2. UC 25 69 l/min
Tractors Z 11741 are equippedwith hydraulic pump UC 25 only,delivering 73 l/min.
Pressure generated in the hydraulicsystem by the hydraulic system pump, islimited with the relief valve to 21 MPa.

ELECTRO-HYDRAULIC SYSTEMSCHEME OF THE EHR B - BOSCHELECTRO-HYDRAULIC SYSTEMOPERATION DIAGRAMThe hydraulic system pump (1) suppliesoil to the additional distributor (2) of thehydraulic system, and from there it isdelivered to the regulating distributor (3),which controls the lifting arm cylinders(4,5) of the hydraulic system.The arms are interconnected with thethree-point hitch lower tie rods where theagricultural implements – lifted, lowered,or kept in required position with respectto the tractor – are suspended.The electronic control unit (6) receiveselectric signals from the dynamometricpins (7) and the sensors of position (8).These signals are confronted with therequired value set up on the controlpanel (9).From the comparison of the required andreal values the resulting regulationdeviation, which is transmitted to theregulating distributor (3). This one isthen readjusted with two proportionalelectromagnets.The lifting and lowering is independenton the load.

ELIMINATING THE BLOCKINGSYSTEMAfter turning on the electrical installationby a key switch (I) the lifting system isstill electronically blocked – it neitherlowers nor lifts. The diagnostic LEDdiode (7) and LED diode of swingcompensator (11) shortly lights – theauto-test of the system runs. LED oflifting (8) and LED of lowering (9) is off.After a short time the status of EHR-Bblocking is signalized by a permanentlight of the diagnostic LED diode (7). Ifthe diagnostic LED diode (7) lightspermanently so the regulation circuitsare disconnected.
Starting the engine is possibleonly with the lever (1) inposition "b".
Electro-hydraulics EHR-B is working withthe running engine only.System of EHR-B can be activated onlyafter turning off the engine lubricationindicator lamp.Eliminating the blocking system (systemactivation) can be turned off only withrunning engine by turning the lifting lever(1) to position "a" – shortly is sufficient.By turning the lever (1) to position (c) thethree point hitch moves into the positionwhich corresponds to the settledcomponents, i.e. according to themomental position of controls (4), (5)and (6).
After activation of system thehydraulic EHR-B first limits thespeed of arm lifting from thesafety point of view.After the first reaching thechosen position of hydraulic armsthis safety limit is eliminated.Afterwards the hydraulic armspeed is normal.

FAST DIPPINGLever (1) in the position "d" – i.e. the freeposition. The lever must be kept in thisposition, because when released, it getsthe position "c" – system operating inaccordance with the setting-up of thecontrollers (3), (4), (5), and (6).
IMPLEMENT TRANSPORTATIONShift the lifting lever (1) to the position”a” and block the traverse lock (2).Blocking the lifting lever (1) in position"a" by a movable lock (2):A - moving the lever is blockedB - moving the lever is not blocked
When the tractor is stopped withthe implements attached, lowerthe implements to the ground (donot leave it with the implementsin the lifted position).
STOP POSITIONWhen shifting the lever (1) to theposition "b" - stop position, the three-point hitch stops moving immediately.

COMPENSATOR OF SWINGINGThis system is used when transportingthe heavy implement, which isimplemented in the rear three pointhitch.The lifting lever (1) must be in position(a) –transport of implement, blocked bya movable lock (2) and compenzator ofswinging (10) is on. Turning on the swingcompensator is signalized by LED (11).After switching the swing compensator(10) the three point hitch arms arelowered approximately 4% down,swinging the arms within approximately8% of lift is enabled by that way.Swinging upwards is always limited byan upper position limit stop (5).
Advantages of the active swingcompensator when transporting theheavy implement in the rear three pointhitch:1. increased safety of transport (the
steered axle is less unbalasted)2. stabilizing the transported
implement3. reduced dynamic load of hydraulic
system and three point hitch
The swing compensator must beturned off when adjusting thepick up hitch.
THREE-POINT HITCH UPPERPOSITION LIMITATIONIt shall be carried out with the lever (5).The limitation maybe performed in theupper half stroke of the three-point hitch.

USE OF THE REAR CONTROLThe rear control is only used for couplingand uncoupling the agriculturalimplements. Lifting lever (1) on thecontrol panel of electro-hydraulics EHR-B must be in position "b" or "c". Thepushbutton symbols shown on bothtractor mudguards correspond to thesense of move of the three-point hitch.The move is only operative while thepushbuttons are depressed.Every use of the rear control makes theregulating system block again, so thatthe whole procedure of Blockingcancellation has to be repeated – seepage 34.

BLOCKING THE SIDE SWINGS OF THELOWER TIE RODSInsert the pin (1) into the hole II(implements of the category II). Thehitch is set in the middle position. A finesetting of the hitch can be carried outwith the help of the bolt (2). The blockingof the tie rod side swings is used fortransporting the attached implementsand for those machine which requireaccurate guiding behind the tractor.In the reinforced three-point hitch it ispossible to adjust the limiting tie rodssmoothly with a slewing collar within thewhole range.
ATTACHING MACHINES TO THREE POINT HITCH WITH CBM HOOKSLower and upper links of hitch are equipped with semi-automatic ends -CBM. Theyserve for easy, two-phase attaching and disattaching the implement to the threepoint hitch without necessary direct action of the driver. They are operated by meansof cables from the driver’s place. Lower links are attached to the implement withinthe first phase at reverse move and by subsequent lifting the three point hitch. Toplink of three point hitch is attached by the driver from the cab within the secondphase. The top link is assembled in one from two openings of the support. First theimplement must be equipped with attaching balls-CBM and the length of hitch axismust be adjusted with adjustable spacer (at reinforced three point hitch only).At tractors equipped with reinforced three point hitch – CBM, the fine adjustment iscarried out by moveable collar with handles.
The collar of lift link must be ever set with handles in direction of driving afteradjusting the length.
