Hoses, Tubes, and Fittings
Inspect all hydraulic hoses, tubes, and fittings for wear,
leakage, or damage (refer to Figure 7.9). Make sure the
hoses are properly routed to avoid sharp edges, kinking,
and scuffing. Inspect the tubes for dents or other damage
that may restrict fluid flow. Make sure all hoses and tubes
are held firmly in their support brackets.
Figure 7.9 – Hoses, Tubes, and Fittings
Hydraulic fluid leaks are easily visible on the ground.
Check under the chassis for fluid that has leaked.
Tires and Wheels
Visually inspect the tires and wheels (refer to Figure 7.10)
to make sure they are suitable for service. Check the
wheel lug nuts to see that none are missing, damaged,
or loose.
Figure 7.10 – Tires and Wheels
The aerial platform has foam filled tires. Foam filled 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 filled tires.
Axle/Boom Interlock
Test for proper operation of the axle/boom interlock sys-
tem from the lower controls with no material or personnel
in the platform.
With the axles retracted and the pin properly locked in
position in the top hole (refer to Figure 7.11), operate the
boom up and extend functions. The boom should only
raise to a few degrees above horizontal and it should only
extend approximately 30 cm (1 ′).
Figure 7.11 – Rear Axles Retracted
Following the instructions in Chapter 8 — Operation, ex-
tend the rear axles but do not install the pin lock.
With the axles extended and the pin out, (refer to Figure
7.12), operate the boom up and extend functions. The
boom should only raise to a few degrees above horizon-
tal and it should only extend approximately 30 cm (1 ′).
Figure 7.12 – Rear Axles Extended
Lock the pin in position in the bottom hole (refer to Figure
7.13) and extend the boom 3 m to 6 m (10 to 20 feet).
