4.1 Towing the machine Troubleshooting

WA80M-7, WA100M-7 – VENAM03001
NOTICE
When the engine is not running, the power steering is inactive.
Steering the machine requires a significantly higher effort in this
case.
If lifting the rear axle of the machine with a crane lorry, the
machine can be towed over longer distances at speeds higher
than 2 km/h. However, remove the cardan shaft of the front axle
first. Furthermore, secure the articulated steering with the safety
bar as during the transport of the machine on a trailer or a railway
carriage.
Towing a machine with defective brakes
WARNING
If the machine to be towed has defective brakes, it may collide
with the towing machine! Always use two machines to tow a
machine with defective brakes. Connect the three machines with
appropriate towing devices.
If you intend to tow a machine with defective brakes or the
machine has to be towed downhill, you need two machines for the
towing process.
Connect the machine to be towed to a larger machine that has
sufficient traction power and braking power. Connect a second
machine to the end of the machine to be towed. This avoids that
the machine to be towed gets out of control.
The towing process can be performed under various circum-
stances, so that it is not possible to define the necessary require-
ments in advance.
Towing on even, level surfaces requires a low traction power
while towing on slopes and on uneven surface requires high trac-
tion power.

a machine.
