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
havethe bottom of the bucket in contact with the ground.
(Never pushwith the teeth). The angle between the boom
and arm should be 90ºt to 110º. 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 nec-
essary, put a board under the bucket also.
STUCK BOTH SIDES OF TRACKS
When the tracks on both sides 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 put the travel levers in the FOR-
WARD position to pull the machine out.
