Hydraulic System
Hydraulic power is supplied from an engine driven vari-
able displacement piston pump.
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 behind the door on the right side
of the turntable. The pump is mounted on the engine.
Fluid Level
To inspect the fluid level:
1. Place the aerial platform on a level surface with the
platform fully stowed.
2. Open the door on the right side of the chassis to ac-
cess the hydraulic fluid level gauge (refer to Figure
7.8).
Figure 7.8 – Hydraulic Fluid Gauge
3. Make sure the fluid level is between the minimum
and maximum lines.
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.

Caution
Even with low voltage electrical systems, severe
arcing can occur. Electrical shock or component
damage may result from contact with energized
conductors. Use caution when working with any
electrical device.
The battery is automatically charged when the engine is
running. Include the battery when inspecting and servicing
the electrical system.
For optimal battery performance the battery fluid level
must be maintained and the battery connections must
be kept clean.
Battery Fluid Level
To inspect the battery fluid level:
1. Remove the caps from the battery (refer to Figure
7.7).
2. Visually check the battery fluid level making sure the
level is within ¼″ (6 mm) of the bottom of the filler
neck inside each hole.
3. If necessary, add distilled water.
Note
Use only distilled water when refilling the battery. Tap
water may contain metallic solids such as iron which can
reduce the life of the battery.
4. Replace the caps on the battery. The caps must be
in place and tight during machine operation.
Battery Terminals
To inspect the battery terminals:
1. Check the top of the battery, the terminals, and cable
ends (refer to Figure 7.7). They should be clean and
free of corrosion.
2. If necessary, clean the top of the battery. Clean the
terminals and cable ends with a wire brush or terminal
cleaning tool.
3. Make sure all cable ends are securely fastened to
the terminals.
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.
