If engine stops
If the engine stops when traveling uphill, lower the bucket to the
ground, stop the machine, then start the engine again.
Precautions on slopes
If the engine stops when the machine is on a slope, never use
G
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
G
a slope. This may cause a sudden change in the operating
force. Always keep the door locked.

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.
