9.7.6
Moving a machine with a defective engine
The fact that the hydraulic drive pump is powered by the petrol engine means that all
hydraulic functions cease to work if the engine is defective. The wheel drive is also hydrau-
lic. Proceed as follows if the 250 kg snow clearer has to be moved and the wheel drive has
ceased to function.
• This procedure must be carried out by at least 2 people.
• Undo the locking nut (1) and then undo the bolts (2) on both sides of the hydrostatic pump.
• The machine will be difficult to move in this manner. In addition to the weight of the
machine, you will also feel the resistance from the hydraulic drive components.
Warning:
Never do so if the machine is situated on an incline. The weight may mean that
the machine would move down the slope at an uncontrollable speed.
9.7.7
Machine deviates from its track
It may happen that when driving straight ahead (joystick vertical position) the machine
deviates from its track. The machine is equipped with a differential, this implies that at the
slightest resistance difference ont he tracks, the differential gives more torque on the track
with the least resistance. Following problems may be the reason:
• Tension tracks not equal. For more information, read § 11.4.3.7
• Malfunctioning of one of the hydraulic brakes. Check the brake discs.
• Guide wheel bearings on the tracks of the driving shaft are dirty or worn. Clean, lubricate
or replace if necessary.
