ESCAPE FROM MUD 3
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.
q
If the machine push-up switch (1) is set to position (b), the
pushing force of the boom is increased to make it easier for
the machine to escape from mud.
Track on One Side Stuck 3
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 inverted 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.
Tracks on Both Sides Stuck 3
When the tracks on both sides are stuck in mud and they slip,
making it impossible for the machine to move, lay boards or
logs as explained above, and dig the bucket into the ground in
front. Then pull in the arm as in normal digging operations and
put the travel levers in the FORWARD position to pull the
machine out.
