HOW TO ESCAPE FROM MUD

Always operate carefully to avoid getting stuck in mud. If the ma-
chine does get stuck in mud, use the following procedures to get
the machine out.
WHEN ONE SIDE IS STUCK
When only one side is stuck in mud, use the bucket to raise the
wheels then lay boards or logs and drive the machine out. If nec-
essary, put a board under the bucket also.
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 BOTH SIDES ARE STUCK
When all wheels are stuck in mud and the machine will not move,
lay boards as explained above, and dig the bucket into the ground
in front. Then pull in the arm as in normal digging operations and
drive machine in required direction to free it from the mud.
