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
Foam filled tires do not have a pressure decal or a valve
core.
To inspect foam filled tires and wheels:
1. Check the wheel lug nuts to see that none are miss-
ing, damaged, or loose.
2. Carefully inspect for large holes or cuts where foam
is coming out of the tire.
3. Look for large embedded objects, such as angle iron,
that can rip a tire open.
Note
Punctures caused by bolts, screws, or nails are not a
problem for foam filled tires.

With no personnel in the platform, test the operation of
each control from the lower controls (refer to Figure 7.7).

2. At the lower controls, pull the emergency stop button
outward. Place the control selector switch in the lower

An alarm sounds when the switch is turned on to warn
others that the machine engine is being started.
• Before starting the engine, check the Diagnostic
Center LCD display window. WAIT TO START will be
displayed if the engine is cold and the engine heater
is on. The message may appear for 1 to 12 seconds,
depending on the engine and ambient air temperature.
• Do not start the engine until the wait message is no
longer displayed.
• If the engine turns over but does not start while the
WAIT TO START message is displayed, turn the
control selector switch to the middle/off position and
back to the lower controls position. Do not start the
engine until the wait message is no longer displayed.
• Hold the switch downward until the engine starts, then
release it to on.
• If the engine dies, the controls switch must be turned
to off before the engine can be restarted.
