Caution
Not all hydraulic uid is suitable to use in the hy-
draulic system. Some have poor lubricating char-
acteristics and may increase component wear. Only
use hydraulic uid as recommended.
3. If necessary, add uid of the proper type.
Note
Refer to Chapter 2 for the proper type and grade of
hydraulic uid to use. The need to regularly add uid
indicates a leak that should be corrected.
4. Replace the cap making sure it is tightly in place.
Hoses, Tubes, and Fittings
To inspect the hoses, tubes and ttings:
1. Inspect all hydraulic hoses, tubes, and ttings for
wear, leakage, or damage (refer to Figure 8.7).
Figure 8.7 – Hoses, Tubes, and Fittings
2. Make sure the hoses are properly routed to avoid
sharp edges, kinking, and scufng.
3. Inspect the tubes for dents or other damage that may
restrict uid ow.
4. Make sure all hoses and tubes are held rmly in their
support brackets.
5. Check under the chassis for uid that has leaked. Hy-
draulic uid leaks are easily visible on the ground.
Free-Wheeling Valve
The free-wheeling valve is located on the hydraulic mani-
fold in the hydraulic tray. Check the free-wheeling valve
to make sure it is fully closed (clockwise).
3. Using the lower controls completely lower the plat-
form.
Cables and Wiring Harness
To inspect the cables and wiring harness:
1. Visually inspect all cables and wiring for wear and/or
physical damage such as loose connections, broken
wires, and frayed insulation.
2. Check the wiring in areas where a change in routing
direction may cause them to become pinched.
3. Make sure the cables and wires are properly routed
to avoid sharp edges, pinching, and scufng.
Hydraulic System
Hydraulic power is supplied from a single stage hydraulic
pump with a 4.25 horsepower DC electric motor.
Danger
Hydraulic uid escaping under pressure can have
enough force to inject uid into the esh. Serious
infection or reaction will result if medical treatment is
not given immediately. In case of injury by escaping
hydraulic uid, seek medical attention at once.
The hydraulic reservoir, pump, lter, and control valve
are located in the hydraulic tray on the right side of the
chassis.
Fluid Level
To inspect the uid level:
1. Make sure the aerial platform is fully stowed on a
level surface.
2. The uid level must be between the add and full
marks (refer to Figure 8.6).
