Parking brake, mechanical release
In case of no servo pressure or a defective travel motor, a manual
release of the parking brake is necessary in order to enable to tow
the machine.
Max. towing speed is 10 km/h (6 mph) and the max. towing
distance is 5 km (3 miles). Exceeding the given limitations will lead
to a damage of the gearbox due to lack of lubrication in the
gearbox. In case of longer distance, the machine needs to be
transported on a trailer.
