DRIVING THE MACHINE
4-7
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 posi-
tion often. Reposition the machine if necessary.
Avoid submerging the swing bearing, swing gears and center
joint.
If the swing bearing, swing gears and center joint are sub-
merged, remove the drain plug to drain mud and water. Clean
swing area. Install plug. Lubricate swing internal gear and
swing bearing.
