Do not use themachine if there is a leak from any system.Check all hydraulic hoses – particularly thosewhich are bent during use – and replace anythat are in poor condition or have leaks. Ensurethat all joins are tight and that the lines are notdamaged. Check that all protective caps andCheck that all hose connectors, lengths andqualities comply with applicable requirements.When replacing or repairing hoses, use originalparts or hoses and connectors recommendedby the manufacturer. Check particularly that thepressure classes of the hoses and connectorsare suitable to the operating pressure levels.Check that all safety devices such as pressurerelief valves, etc., are in place and work properly.Familiarize yourself with their use.Safety systems may never be bypassed.Check the main hydraulic parts daily, andalways after a fault. Replace any damagedparts immediately.If a component is damaged, clean it beforerepairing it. Do not use solvents when cleaningparts.Do not attempt to carry out repairs that you arenot fully familiar with.Never carry out repairs of the hydraulic circuitwhen the system is pressurized. Whenpressurized, the oil spray can penetrate the skinand cause mortal danger.Never work below a device or component that isonly being held up by hydraulics.Use separate supports when carrying ourmaintenance or repairs. Do not disconnectcylinders or their valves until the machine is wellsupported.Most hydraulic oils do not evaporate easily. Riskfactors include hot oil, spills and oil mist(pressurized).If oil gets into your eyes, rinse with plenty ofwater and contact a doctor.Avoid prolonged or repeated contact with yourskin.14. If sprays or contact with the skin cannot beavoided, use protective gloves, goggles andclothing as necessary. Do not use oily clothing.15. Avoid discharging hydraulic oil into theenvironment, as it can pollute waterways andthe groundwater. When working in ecologicallyvulnerable areas, use biofuel.16. Store the oil in sealed containers provided bythe manufacturer. Try to transfer the oil directlyfrom its container into the tank.17. If the oil must be passed through other containers,ensure that they are completely clean. Caps,clean.18. Never store oil outdoors, as water could condensein it.19. Always dispose of oil in a suitable container,never into the environment!7

Theadjuster has three positions: empty, half-load andfull load, to describe the load on the trailer.CONTROL SYSTEM• The trailer is controlled from a control panelthat has a driving direction selector (A) and atractive force adjusting wheel.• The tractive force is increased by turning theadjusting wheel clockwise. When theadjusting wheel is completely closed, thetractive force is at its maximum. The tractiveforce can be reduced gradually to zero byopening the adjusting wheel anticlockwise.emptyhalf-loadfull loadidleThe adjuster has three positions:empty, half-load and full load.14

Open it (anticlockwise)by at least one turn.• Before setting the machine in motion, ensurethat the brakes are off.15

PROFDRIVE 10-2WD / 12-2WDCOORDINATING THE TRACTIVE SPEEDSOF THE TRAILER AND TRACTOR1.2.3.Switch the pump on.Push the tractor with the trailer’s drive, with thetractive force adjusting wheel closed. If yourtractor’s power take-offcan be either 540 rpm or1000 rpm, it is better to choose 540 rpm.tractor.!CAUTION!If you use the power take-offat 1000 rpm, the axle revolutionsmust not exceed 740rpm. Check your tractor tosee what engine revolutionreading gives 740 rpm forpower take-off.Adjust the tractor speed to be slightly faster thanthe trailer’s drive.DRIVING!CAUTION!!CAUTION!!CAUTION!Do not drive at maximumspeed unless necessary.Driving at maximum speedoverloads the hydraulicsystem and structures. Thedrive will be unpleasant andcan be dangerous on bends.Avoid switching on thetrailer’s drive or changingthe driving direction whenthe transmission shaft’srevolutions are high, as thiscan cause a violent jerk.When the trailer’s drive isswitched on, do not tow thetrailer at speeds that exceedthe maximum for the pump’soutput: max. 4.8 km/h at apump output of 85 l/min.1.2.3.4.•••Select the appropriate driving speed for thetractor.Select the direction with the switch.If necessary, increase the tractive force usingthe adjusting wheel. Do not tow at full forceunless absolutely necessary; it will wear thehydraulics and structure, causes the driveto be unpleasant, and can be dangerous onbends.To switch off traction, turn the direction switchto idle.You can tell if the tractive force is too large fromthe vibration of the traction motor and from theclunking sounds it makes.Do not brake abruptly and forcefully; try tobrake softly.If using hydraulic shaft control, do not place anabrupt force on the pivot cylinders.DO NOT CHANGE THEDRIVING DIRECTION WHENTHE MACHINE IS IN MOTION!! The driving direction mayonly be changed when theCAUTION!machine is stationary.Changing the driving direction when themachine is in motion will damage the tractionmotors and tires.!CAUTION!Note that under prolonged,constant traction, thehydraulic oil will heat up.16
