OPERATION

ESCAPE FROM MUD

Always operate carefully to avoid getting affixed in mud. If the machine does get affixed in mud, do as follows to
get the machine out.

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.
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 affixed in mud, use the bucket to raise
the track, then lay boards or logs and drive the machine out.

Stuck Both Sides Of Tracks

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.
