ENGLISH
PUSHING/TOWING THE MACHINE
CAUTION!
The hydraulic pump can be damaged if the machine is towed when the screw is in the normal working position
(locked).
The machine hydraulic pump (45) is equipped with a screw that disengages the traction system. The system prevents damage to
the hydraulic system when the machine is being towed/pushed short distances without using the engine.
1. To access the unlocking screw, open the engine compartment hood (1) by using the unlocking push-button (25) and locate the
hydraulic pump (45) in the front part of the engine (44).
2. Remove the supplied wrench (A, Fig. 1) on the pump lever.
3. With the wrench, turn the socket head screw (B) 1/4 of a turn counter-clockwise (C) to disengage the hydrostatic lock between
the engine and pump.
4. Tow or push the machine no faster than a normal walking pace [2-3,5 mi/h (3-4.5 km/h)] and for short distances only.
NOTE
If the machine is to be moved long distances the driving wheels need to be raised off the floor and placed on a suitable
transport dolly.
5. After pushing/towing the machine, turn the socket head screw 1/4 of a turn clockwise (D) to reset the hydrostatic lock and
hydraulic functions.
NOTE
If the screw is left in unlocking position (C), the hydraulic pump cannot drive the machine.
