SAFETY HINTS FOR THE USERDRIVING OPERATION11. Check the hoses of hydrostaticsteering, brakes, and fuel system forproper conditions. In case of detectingany symptoms of damage, replace thehoses immediately. Cracks on the hosesurface, loss of the hose fitting pre-tensioning (which can be proved by itseasy removal from the socket) and itsmechanical damage are such symptoms,for instance.Hoses with specified servicelife shall be replaced as soon as theirservice life expires.12. In case the tractor uses bio-fuels forits operation, its fuel system shall befitted with REP hoses. (Themanufacturer furnishes the fuel systemwith REP 6 hoses).13. Brakes and steering shall be kept inperfect conditions.14. When driving on roads, with trailers,and implements, the pedals shall belatched together.15. Driving downhill with no speed gearengaged is forbidden!16. Special caution shall be paid indriving through slopes, muddy, sandy,icy and uneven terrain.17. Do not exceed the admissible 12°-slope sheerness.18. Do not exceed the maximum overallweight of the rolling stock as given at the

tractor rating plate or at the rear wheelmudguard.19. Do not apply the differential lockwhen driving through turnings.20. To get in and out the tractor duringits move is strictly forbidden.21. When driving with implementsattached to the rear hitches, the load ofthe steering axle may not drop below18 % of the rolling stock instantaneousweight.22. When driving the tractor with theagricultural implements suspended atthe front three-point hitches, reduce thetractor travel speed to 20 km/h.23. When combining the Z 8641 - Z 11741tractors with the machines and implementsof high hauling resistance when the enginespeed decays and the motor tends to stop,it is forbidden to use the reduced speedgears 1R, 2R (because of the danger ofshaft torsion).TRANSPORT OF PERSONNEL,OPERATION24. Tractor may only transport as manyindividuals as specified in the tractortechnical certificate.25. Individuals not charged with theoperation of the tractor additionalimplements, are not allowed to staybetween the tractor and the suspendedmachine (implement).

26. Before starting the tractor move,make sure that no unauthorizedindividual or obstacle obstructs thetractor move.27. Do not exceed the specified angle ofslope gradient, which for the Z 8641,Z 9641, Z 106 41, Z 114 41 andZ 117 41 tractors equals 12°.TRACTOR RESCUE AND PUSHING28. To recover the stack tractor use atow bar or cable suspended at the fronthook.!

Never use chains, becausetheir rupture represents amortal danger!

29. During the recovery, it is dangerousto stay close to the tow cable.30. It is forbidden to use the tractor axle(the individual drive wheels) as a winchfor recovering the tractor.31. The front hook is intended for towingor recovering the tractor alone, i.e.without the trailer or other suspendedimplements.32. Never recover the tractor with thereduced speed gears engaged.33.

LEAVING THE TRACTOR34. Do Not park the tractor with theattached implements in the liftedposition.35. Before leaving the tractor, do notforget to apply the parking brake (withengaging a speed gear). Remove thekey from the switch box and lock up thecab with key.36. In the tractors fitted with reversingsystem, shift the reversing lever to theforward-drive position.37. When leaving the tractor while theengine is in operation, apply the parkingbrake.38. For getting out of the tractor, makenormally use of its L.. H. side. Whendoing it, be sure that no vehicle, whichcould menace your safety, approaches.Then open the door.39. When getting out, make use of stepsand handles. Pay special attention to thegearshift lever, the hand-operated fuelsupply lever, and to the upper step.

OPERATIONS TO BE DONE WITH THESTOPPED ENGINE ONLY:40. All the operations associated with thetractor or implement refueling, cleaning,lubrication / greasing, and setting –excepting the checks of brake, hydraulic,and electrical charging systems forproper conditions - shall be carried out

with the engine and other moving partsstopped.41. Before removing the bonnet sidecovers, stop the engine. Inside theclosed buildings, the tractor motor mayonly be put into operation if sufficientventilation is ensured. Remember thatthe exhaust gases are harmful.

PRINCIPLES OF FIRE PREVENTION42. Refuel the tractor preferably afterconcluding the work and with the enginestopped..43. In summer season, do not refuel upto the top. Wipe off the spilled fuelimmediately.44. Do not refuel close to naked flamesand do not moke45. When checking the storage batteryelectrolyte for proper level, do notsmoke, nor use the naked flames.46. In the environments of enhanceddanger of fire (haylofts, straw heaps, andthe like) be consequent in attaining tothe fire fighting safety instructions.47. 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.

11


WASTE DISPOSAL

53. When disposing the tractor or someof its parts (including the service liquids),as soon as their service life is over,every body is obliged to proceed inaccordance with the provisions of therelevant laws and regulations. In themanufacturer’s country it is the Law No.185 2001 coll. on wastes (§ 36 to 38)together with its procedural regulations(particularly the decree of the Ministry ofLiving Environment No. 383/2001 coll.dealing with details on wastemanipulation - § 18 a 19).The last tractor seller is obliged – by theLaw on wastes – to inform the consumer– when selling the tractor – on the waysof taking back some of the consumedparts of the tractor. In question are theoils and other service liquids, storagebatteries, and tires. These componentsmust be accepted back from theconsumer free of charge.

PREVENTIVE DAILY MAINTENANCE54. This maintenance shall be carriedout daily or at latest after every 8 to 10operating hours.

SAFETY CAB55. In case corrosion or any otheraccident damages the cab-protectingframe, the cab must be replaced.

AIR CONDITIONING56. In no case it is allowed todisassemble, turn or manipulate inanother way the screw joints of the airconditioning system, because suddenleak of the coolant and quick localcooling may occur. Contact or freezingof components in hands may result inserious injury of some tissues.57. The air conditioning system is fittedwith quick couplers, which allowseparate the cab from the tractor body ifnecessary without any leak of thecoolant. Entrust the interventions into theair conditioning system to the servicespecialists.

ELECTRICAL EQUIPMENT

58. No additional interventions intothe tractor electrical equipment(connection of other electricalappliances) are allowed because of itspossible overloading.59. The values of electrical installationare:Nominal voltage 12 V =Ground minus pole ( - )The use of starting trucks or startingaid devices with different voltage orpolarity causes serious failures oftractor.

60. It is necessary to be careful whenmanipulating with the battery and toavoid short circuits. Turn off thebattery switch at tractors equippedwith this switch when manipulatingwith the battery.61. Tractors Z 8641- Z 11741 must notrun with the disconnected battery, theserious failure of tractor is possible.

HYDRAULIC SYSTEM

F_02_113

HYDRAULIC SYSTEM PUMPThe hydraulic pump cannot be switchedoff. As long as the engine is running, thepump is operating.The pump is alternatively supplied in twosizes:

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.

32

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.

DEVICE SWITCHED OFFElectric installation switched off with theswitch box key. The electronic system isswitched off, the lifting device is blocked.

34


F_02_164 F_02_163

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.

F_02_165 F_02_166 F_02_167

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.

36


F_02_168 F_02_169

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.

Symbol of positionalregulation

The regulating operations (lifting andlowering) can be monitored withindicating diodes (8) and (9). At theheadland shift the lever (1) to theposition "a", and after turning the tractor,shift it back to the position "c". Theregulating system occupies thepreceding working position (plowingmemory). The controller (3) serves forsetting up the required lowering rate.

F_02_98 F_02_78 F_02_65

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.

ELECTRO-HYDRAULIC SYSTEMEXTERNAL CONTROL PUSHBUTTONS1. Lifting2. LoweringThe motion is only operative while thepushbuttons are depressed.

Push buttons of electro-hydraulicouter control are functional alsowithout the previous activation.

USE OF PUSHBUTTONSWhen manipulating the three-point hitch by means of electricalbuttons, the operator must keepoff the area of implementconnection for avoiding hiscatching and injury with theimplement being manipulated.

HITCHES

F195a F194

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.
