Check the Hydraulic Oil Level
Maintaining the hydraulic oil at the proper level is
essential to machine operation. Improper hydraulic
oil levels can damage hydraulic components. Daily
checks allow the inspector to identify changes in oil
level that might indicate the presence of hydraulic
system problems.
1 Be sure the boom is in the stowed position and
the outriggers are raised.
2 Open the cover on the side of the machine
opposite the ground controls.
3 Use the marks on the side of the hydraulic tank
to determine the level of hydraulic oil.
Result: The hydraulic oil level should be
between the
ADD
and
FULL
marks.
4 Add hydraulic oil if necessary.

MAINTENANCE
Check the Tires and Wheels
Bodily injury hazard. An over-
inflated tire can explode and may
cause death or serious injury.
Collision hazard. An excessively
worn tire can cause poor handling
and continued use could result in
tire failure.
Tip-over hazard. Do not use
temporary flat tire repair products.
Maintaining the tires and wheels in good condition
is essential to safe operation and good
performance. Tire and/or wheel failure could result
in a machine tip-over. Component damage may
also result if problems are not discovered and
repaired in a timely fashion.
1 Check the tire surface and sidewalls for cuts,
cracks, punctures and uneven or excessive
tread wear.
Result: Replace the tire if uneven or excessive
tread wear is found.
Tires and wheels must be replaced
with tires and wheels of the
specifications listed.
2 Check each wheel for damage, bends and
cracks.
Result: Replace the wheel if any damage is
found.
3 Check each tire with an air pressure gauge and
add air as needed.
4 Check the torque of each lug nut.
