Traveling On Soft Ground - Hitachi ZAXIS 17U-5N Owner'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 its
own propelling power. Towing the machine may become
necessary. Do not drive the machine to a deeper location
than towing the machine is possible.
• In case it becomes impossible for the machine to travel
by its 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, the arm, and the 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 each 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 caught rocks and/or mud from the track.
• Tow the machine with another machine if the machine
becomes stuck in soft ground and impossible to evacuate
by its own propelling power. Refer to the descriptions for
TOWING MACHINE for the correct usage of wire ropes.
