Figure 7.8 – Hoses, Tubes, and Fittings
Hydraulic fl uid leaks are easily visible on the ground.
Check under the chassis for fl uid that has leaked.
Tires and Wheels
Visually inspect the tires and wheels (refer to Figure
7.9) to make sure they are suitable for service. Check
the wheel lug nuts to see that none are missing, dam-
aged or loose.
Figure 7.9 – Tires and Wheels
The aerial platform has foam fi lled tires. Foam fi lled tires
do not have a pressure decal or a valve core.
Inspect for large holes or cuts where foam is coming
out of the tire. Look for large imbedded objects, such
as angle iron, that can rip a tire open.
Punctures caused by bolts, screws or nails are not a
problem for foam fi lled tires.
Axle/Boom Interlock
Test for proper operation of the axle/boom interlock
system from the lower controls with no material or per-
sonnel in the platform.
With the axles retracted and the pin properly locked in
position in the top hole (refer to Figure 7.10), operate
the boom up and extend functions. The boom should
only raise to a few degrees above horizontal, at which
point it will stop. After resetting it to the original position,
extend the boom, it should only extend approximately
1 m (3 ′).
Figure 7.10 – Rear Axles Retracted
Following the instructions in Chapter 8 — Operation,
extend the rear axles but do not install the pin lock.
