MACHINE OPERATION
4-23SY95C Excavator OMM
0003887
Figure 4-52
Never let the machine make contact with power lines or
bridges (2).
Do not drive or swing the machine on broken stones,
rugged surfaces, steel bars, or scrap iron. This could
cause personal injury or damage to the track.
Slow the machine when traveling on uneven ground. A
lower speed reduces the possibility of machine damage.
Do not operate the machine on a surface covered by
small stones that could cause track skidding or damage.
Avoid premature track wear or damage. Do not operate
the machine on new asphalt or other hot surfaces.
Do not allow fuels, oils, salt, or chemical solvents to
make contact with the tracks. These substances will
erode the track links and cause rusting and peeling.
Wash these substances off the tracks immediately with
clean water.
Do not operate the machine in a marine environment.
Salt in seawater can damage the track shoe cores.
Traveling at High Speed
When traveling at high speeds, position the idlers to the
front of the cab. See “Standard Travel Direction” on
page 4-17.
Operating in Water
0003888
Figure 4-53
• 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 shoe 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 and the
radiator fan may sustain water damage.
Failure to follow this notice could damage the
machine or cause it to operate improperly.
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). See “Recommended Lubricants,
Fuel, and Engine Coolant” on page 5-7.
Make sure that the job site surface is hard enough for the
machine.
0003889
Figure 4-54
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, or
swivel area (2) do not become submerged in water.
NOTE: If the swing bearing, swing drive gear, or swivel
area have been submerged in water, they must be
cleaned. Lubricate the swing drive gear and swing
bearing.
