Traveling On Soft Ground - Hitachi ZAXIS 30U-5N Operator's Manual

Traveling on Soft Ground

Avoid traveling on soft ground as much as possible. If traveling
on a soft ground is unavoidable, carefully operate the machine
while observing the following points.
• Drive the machine as far as the machine can move by
own propelling power. Towing the machine may become
necessary. Do not drive the machine to a deeper location
than towing machine is possible.
• In case it becomes impossible for the machine to travel by
own propelling power, lower the bucket to the ground.
While supporting the machine weight with the boom and
the arm, slowly pull the arm to evacuate the machine.
Operate the boom, arm, and travel levers simultaneously
at this time to prevent the machine from being loaded
abnormally.
• If the track frame bottom comes in contact with the
ground, or if mud and/or grabbles are tightly packed into
the undercarriage, the machine may become impossible
to travel. Raise one side track above the ground with the
boom and arm extended, remove mud and/or grabbles
from the track. Then, evacuate the machine. Rotate the
raised track in forward or reverse directions alternately to
remove the packed rocks and/or mud from the track.
• Tow the machine with other machine if the machine
becomes stuck in soft ground and impossible to evacuate
by own propelling power. Refer to the descriptions for
TOWING MACHINE for the correct rope attaching method.
