A
Caution
Not all hydraulic fl uid is suitable to use in the hydrau-
lic system. Some have poor lubricating character-
istics and may increase component wear. Only use
hydraulic fl uid as recommended.
4. If necessary, add fl uid of the proper type.
Note
Refer to Chapter 2 for the proper type and grade of
hydraulic fl uid to use. The need to regularly add fl uid
indicates a leak that should be corrected.
5. Replace the cap making sure it is tightly in place.
Hoses, Tubes, and Fittings
To inspect the hoses, tubes and fi ttings:
1. Inspect all hydraulic hoses, tubes, and fi ttings for
wear, leakage, or damage (refer to Figure 8.6).
2. Make sure the hoses are properly routed to avoid
sharp edges, kinking, and scuffi ng.
3. Inspect the tubes for dents or other damage that may
restrict fl uid fl ow.
4. Make sure all hoses and tubes are held fi rmly in their
support brackets.
5. Check under the chassis for fl uid that has leaked. Hy-
draulic fl uid leaks are easily visible on the ground.
Tires and Wheels
Visually inspect the tires and wheels (refer to Figure 8.7)
to make sure they are suitable for service.
Figure 8.7 – 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.
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 scuffi ng.
Hydraulic System
Hydraulic power is supplied from a single stage hydraulic
pump with a 4 horsepower DC electric motor.
A
Danger
Hydraulic fl uid escaping under pressure can have
enough force to inject fl uid into the fl esh. Serious
infection or reaction will result if medical treatment is
not given immediately. In case of injury by escaping
hydraulic fl uid, seek medical attention at once.
The hydraulic reservoir is inside the hydraulic tray on the
left side of the chassis.
Fluid Level
To inspect the fl uid level:
1. Make sure the aerial platform is fully stowed on a
level surface.
2. Open the hydraulic tray on the left side of the chas-
sis to access the hydraulic fl uid tank (refer to Figure
8.6).
Figure 8.6 – Hydraulic Tray
3. Remove the fi ller cap and check the fl uid level on the
dipstick. The fl uid should be between the minimum
and maximum lines.
