Operating In Water Or Mud - Hitachi ZAXIS 30U-5N Operator's Manual

Operating in Water or Mud

The machine can be operated in water up to the upper edge of
the upper rollers only if worksite footing has sufficient strength
to prevent the machine from sinking past the upper edge of
the upper roller, and only if the water is flowing slowly.
When operating in such conditions, check the machine's
position often. Reposition the machine if necessary.
Avoid submerging the swing bearing, swing gears and center
joint.
IMPORTANT: If the swing bearing, swing gears and center
joint are submerged in water or mud by mistake,
premature wearing on parts such as the swing bearing
may result. Grease must be changed or overhauling
will be required immediately. Stop operating the
machine as soon as possible, and contact your
authorized dealer.
