A
Caution
Even with low voltage electrical systems, severe
arcing can occur. Electrical shock or component
damage can result from contact with energized con-
ductors. Use caution when working with any elec-
trical device.
The batteries are behind the door on the right side of the
turntable.

Emergency Power Battery

The emergency power battery (refer to Figure 7.7) is be-
hind the door on the right side of the chassis. The battery
is automatically charged when the engine is running.
Include the emergency power battery when inspecting
and servicing the electrical system.

Battery Fluid Level

Remove the caps from each battery (refer to Figure 7.7).
Visually check the battery fluid level. If the level is not
" (6 mm) of the bottom of the filler neck inside

each hole, add distilled water.
Replace the caps on the batteries. The caps must be in
place and tight during machine operation.

Battery Terminals

Check the top of the batteries, the terminals, and cable
ends (refer to Figure 7.7). They should be clean and free
of corrosion. Clean the top of the batteries if necessary.
Clean the terminals and cable ends with a wire brush or
terminal cleaning tool. All cable ends must be securely
fastened to the terminals.

Cables and Wiring Harness

Inspect all cables and wiring for wear and/or physical
damage such as loose connections, broken wires, and
frayed insulation. Check the wiring in areas where a change
in routing direction may cause them to become pinched
(refer to Figure 7.8). Make sure the cables and wires are
properly routed to avoid sharp edges, pinching, and scuff-
ing.

Hydraulic System

Hydraulic power is supplied from an engine driven vari-
able displacement piston pump.
A
Danger
Hydraulic fluid escaping under pressure can have
enough force to inject fluid into the flesh. Serious
infection or reaction can result if medical treatment
is not given immediately. In case of injury by escap-
ing hydraulic fluid, seek medical attention at once.
The hydraulic reservoir is behind the door on the left side
of the turntable. The pump is mounted on the engine.

Fluid Level

Check the hydraulic reservoir fluid level with the aerial
platform stowed on a level surface. The fluid level must
be between the full and add marks as viewed on the sight
glass (refer to Figure 7.9).

A
Caution
Not all hydraulic fluid is suitable to use in the hy-
draulic system. Some have poor lubricating char-
acteristics and can increase component wear. Only
use hydraulic fluid as recommended.
