3.23 Operation
Precautions on slopes
If the engine stops when the machine is on a slope, never use
the left work equipment control lever to carry out swing opera-
tions. The upper structure will swing under its own weight.
Do not open or close the door on the cab if the machine is on a
slope. This may cause a sudden change in the door opening/
closing force. Always keep the door locked.
WARNING
If it becomes necessary to tow the machine the operator
must not operate the travel system when the transmission
disengagement pin is rotated.
Failure to comply with this notice will result in severe dam-
age to the transmission unit.
If you are uncertain about how to tow the machine, please
contact your local KOMATSU distributor for advice.
3.23.20 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.
NOTE
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.
