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.
Hydraulic fluid leaks are easily visible on the ground.
Free-Wheeling Valve
The free-wheeling valve is on the hydraulic manifold in the
control valve tray. On some manifolds the valve is on the
side and on others it is on the back (refer to Figure 8.7).
Check the free-wheeling valve to make sure it is in its
normal operation position.
Diagnostic Center Display
To test the diagnostic center display in the con-
trol valve tray (refer to Figure 8.7), from the lower
controls:
1. Turn the battery disconnect switch to the on posi-
tion.
2. Pull the emergency stop button outward to the on
position.
3. The display on the LCD screen should indicate:
y
The accumulated aerial platform operating
time.
y
The available battery power to operate the ma-
chine.
Tires and Wheels
Visually inspect the tires and wheels (refer to Figure 8.8)
to make sure they are suitable for service.
Figure 8.8 – Tires and Wheels
To inspect the tires and wheels:
1. Visually inspect the tires. They should be smooth
without any cuts, gouges, or missing rubber that
might affect aerial platform stability.
2. Check the wheels to see that the fasteners are in
place and are not damaged or loose.
Ground Strap
Make certain the ground strap (refer to Figure 8.9) is se
-
curely fastened to the chassis. It should be long enough
to contact the ground surface to eliminate static electricity
from the machine.
