Operating in Water
• Do not drive the machine into water where the water
depth is above the center of the final drive sprocket (1).
• Grease the parts that have been submerged until the old
grease has been displaced from the bearing (especially
from the bucket pin).
• Make sure that the job site surface is hard enough for
the machine.
• Continuously monitor the condition of the machine
when operating in water. Move the machine to a
different location if necessary.
• Make sure that the swing bearing, swing drive gear,
and swivel do not become submerged in water.
NOTE: If the swing bearing, swing drive gear, or
swivel have been submerged in water, they
must be cleaned. Lubricate the swing drive
gear and swing bearing.
NOTICE!
• Operate the machine slowly when traveling through water. Check the depth of the water
with the bucket.
• Do not operate the machine in a marine environment. Salt in seawater can damage the
track cores.
• When driving the machine out of water on a grade steeper than 15°, the rear of the upper
structure may be submerged in water. The radiator fan may sustain water damage that can
result in damage to the machine or cause the equipment to operate improperly.
