3.3.11 GETTING THE MACHINE OUT OF MUD
Always proceed carefully to avoid getting stuck in mud. However, if the machine gets stuck in mud, proceed as in-
dicated below.
WHEN ONE SIDE ONLY GETS STUCK
IMPORTANT
q
When using the boom or arm to raise the machine, always
place the bottom of the bucket in contact with the ground.
(Never push with the bucket teeth.) The angle between the
boom and the arm should be included between 90° and
110°.
When only one side gets stuck in mud, use the bucket to raise the
track, then lay boards or logs under the track and drive the ma-
chine out.
BOTH TRACKS STUCK IN MUD
If both tracks are stuck in mud and the machine slips and cannot
move, put logs or wooden blocks under the machine, proceeding
as indicated above. Thrust the bucket into the ground in front of
the machine, operate the arm in the same way as for digging
work, and shift the travel levers forward to drive the machine out.
