Battery Fluid Level
Remove the caps from each battery. Visually check the
battery fluid level. If the level is not within 6 mm ( 1 /
4
″) of
the bottom of the filler neck inside each hole, add dis-
tilled 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. 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 7.7). 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 7.8).

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.
If necessary, remove the filler cap and add fluid of the
proper type. 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.
The sight glass on the reservoir has an internal thermom-
eter to measure the fluid temperature. The temperature
should be less than 93°C (200°F).
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.
