MACHINE OPERATIONS AND CONTROLS

ESCAPE FROM MUD

When operating, be careful not to get stuck in mud. If the machine gets stuck in mud, do as follows to get the
machine out.
If machine push-up switch (1) is turned ON, the pushing force of
the boom is increased and it becomes easier to escape.
Stuck One Side of Track
NOTICE
When using the boom or arm to raise the machine, always have the bottom of the bucket in contact with the ground. (Never push
with the teeth). The angle between the boom and arm should be 90° to 110°.
The same applies when using the inverting bucket.
When only one side is stuck in mud, use the bucket to raise the
track, then lay boards or logs and drive the machine out. If
necessary, put a board under the bucket also.
Stuck Both Sides of Tracks
If the track on both sides are in mud and the machine slips and
cannot move, use the procedure given above to lay logs or timber.
dig the bucket into the ground at the front, operate the arm in the
same way as when digging, and set the travel lever to FORWARD
to pull the machine out.
