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 scuffing.
Hydraulic System
Hydraulic power is supplied from a single stage hydraulic
pump with a four horsepower DC electrical motor.
Danger
Hydraulic fluid escaping under pressure can have
enough force to inject fluid into the flesh. Serious
infection or reaction will result if medical treatment is
not given immediately. In case of injury by escaping
hydraulic fluid, seek medical attention at once.
The hydraulic reservoir is inside the right side of the
chassis.
Fluid Level
To inspect the fluid level:
1. Make sure the aerial platform is fully stowed on a
level surface.
2. Remove the drive control compartment cover at the
rear of the chassis.
3. Visually check to make sure the fluid is visible in the
sight glass (refer to Figures 8.6).
Figure 8.6 – Hydraulic Fluid Gauge
Caution
Not all hydraulic fluid is suitable to use in the hydrau-
lic system. Some have poor lubricating character-
istics and may increase component wear. Only use
hydraulic fluid as recommended.
4. If necessary, remove the filler cap and add fluid of
the proper type. Replace the cap making sure it is
tightly in place.
Note
Refer to Chapter 2 for the proper type and grade of
hydraulic fluid to use. The need to regularly add fluid
indicates a leak that should be corrected.
Fluid Filter
Checking the condition of the hydraulic fluid filter is part
of the machine maintenance schedule and should not be
performed by the operator.
Hoses, Tubes, and Fittings
To inspect the hoses, tubes and fittings:
1. Inspect all hydraulic hoses, tubes, and fittings 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 scuffing.
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. Hy-
draulic fluid leaks are easily visible on the ground.
