2. Make sure the hoses are properly routed to avoid
sharp edges, kinking, and scuffing.
3. Inspect the tubes for dents or other damage that may
restrict fluid flow.
4. Make sure all hoses and tubes are held firmly in their
support brackets.
5. Check under the chassis for fluid that has leaked. Hy-
draulic fluid leaks are easily visible on the ground.
Tires and Wheels
Visually inspect the tires and wheels (refer to Figure 7.8)
to make sure they are suitable for service.
Figure 7.8 – Tires and Wheels
The aerial platform may have air or foam filled tires.
Different types of tires have different inspection require-
ments.
Air Filled
Air filled tires have a tire pressure decal near the valve
stem. The valve stem also has a valve core like an au-
tomobile tire.
A
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not operate the aerial platform if a tire is
leaking air or is in poor condition where a blow out
could occur.
To inspect air filled tires and wheels:
1. Check the wheel lug nuts to see that none are miss-
ing, damaged, or loose.
2. Carefully inspect the tires for wear, cuts, punctures,
or imbedded objects.

Caution
Not all hydraulic fluid is suitable to use in the hydrau-
lic system. Some have poor lubricating character-
istics and may increase component wear. Only use
hydraulic fluid as recommended.
4. If necessary, remove the filler cap and add fluid of
the proper type. Replace the cap making sure it is
tightly in place.
Note
Refer to Chapter 2 for the proper type and grade of
hydraulic fluid to use. The need to regularly add fluid
indicates a leak that should be corrected.
Fluid Filter
Checking the condition of the hydraulic fluid filter is part
of the machine maintenance schedule and should not be
performed by the operator.
Hoses, Tubes, and Fittings
To inspect the hoses, tubes, and fittings:
1. Inspect all hydraulic hoses, tubes, and fittings for
wear, leakage, or damage (refer to Figure 7.7).
