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 to make sure
they are suitable for service. Check the wheel lug
nuts to see that none are missing, damaged, or
loose.The aerial platform has foam filled tires.
Foam filled tires do not have a pressure decal or a
valve stem. Different types of tires have different
inspection requirements.
❑ Foam Filled
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.
■ Ground Control Station
With no personnel in the platform, test the
operation of each control from the ground controls
(refer to Figure 6.11).
