Note
Refer to Chapter 2 for the proper type and grade of
hydraulic fl uid to use. The need to regularly add fl uid
indicates a leak that should be corrected.

Fluid Filter

Checking the condition of the hydraulic fl uid fi lter 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 fi ttings:

1. Inspect all hydraulic hoses, tubes, and fi ttings for

wear, leakage, or damage (refer to Figure 7.7).

Figure 7.7 – Hoses, Tubes, and Fittings

2. Make sure the hoses are properly routed to avoid

sharp edges, kinking, and scuffi ng.

3. Inspect the tubes for dents or other damage that may

restrict fl uid fl ow.

4. Make sure all hoses and tubes are held fi rmly in their

support brackets.

5. Check under the chassis for fl uid that has leaked. Hy-

draulic fl uid 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 has air fi lled tires. Air fi lled tires have

a tire pressure decal near the valve stem. The valve stem

also has a valve core like an automobile tire.

Danger

The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tipover 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 fi lled 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.

3. Test the air pressure with a pressure gauge to make

sure the tires are properly infl ated. Check the tires

several times throughout the day to see that they are

properly infl ated.

Lower Control Station

With no personnel or materials in the platform, test the

operation of each control from the lower controls (refer

to Figure 7.9).
