MACHINE OPERATIONS AND CONTROLS
OPERATION
3-120
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
Place the machine push-up switch at high-pressure set
position (b). This will increase the pushing power of the
boom and make it easier to escape.
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.
The angle between the boom and arm should be 90° to
110°.
The same applies when using the bucket installed in the
reverse direction.
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.
