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
indicated below.
When one side only gets stuck
NOTICE
When the 1st or 2nd boom is used to lift the machine,
always place the lower part of the bucket in contact with
the ground. (Never push with the bucket teeth.) The angle
between the 1st and the 2nd boom must be within 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
machine 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.
