3.7.3 REMOVING THE MACHINE
WARNING
q
When removing the machine, use a metal cable suitable for

When the machine is stuck in mud and cannot get out with its own
power, or in case of failure, before removing it pass wire cables
around the central part of the undercarriage, as shown in the dia-

Position wooden blocks between the wire cables and the machine

self.
