Operating In Water Or Mud - Hitachi EX1900-5 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 suffi-
cient strength to prevent the machine from sinking past the
upper edge of the upper roller, and only if the water is flow-
ing 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 cen-
ter joint.
If the swing bearing, swing gears and center joint are sub-
merged, remove the cover to drain mud and water. Clean
swing area. Install cover. Lubricate swing internal gear and
swing bearing.
Lubricate swing bearing. (See Maintenance Guide,
