from the outrigger controls (refer to Figure 7.7).
Figure 7.7 – Outrigger Controls

Inspect for hydraulic oil leaks and make sure the legs
and shoes are free of deformation and damage.

Make sure that each outrigger leg will fully extend
and retract.
Bubble Levels
Visually inspect the bubble levels. Make sure they are
properly attached to the chassis and are not damaged.
Lower Control Station
With no personnel or materials in the platform, test the
operation of each control from the lower controls (refer
to Figure 7.8).

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 7.6)
to make sure they are suitable for service.
Figure 7.6 – Tires and Wheels
The aerial platform has foam filled tires. Foam filled tires
do not have a pressure decal or a valve core.
To inspect the tires and wheels:
1. Check the wheel lug nuts to see that none are miss-
ing, damaged, or loose.
2. Inspect for large holes or cuts where foam is coming
out of the tire. Look for large embedded objects, such
as angle iron, that can rip a tire open.
