with energized conductors. Use caution
when working with any electrical device.
The battery is under the cover on the right side of
the turntable.
❑
Battery Fluid Level
Remove the caps from the battery. Visually check
the battery fluid level. If the level is not within (6 mm)
of the bottom of the filler neck inside each hole, add
distilled water.
Replace the caps on the battery. The caps must be
in place and tight during machine operation.
❑
Battery Terminals
Check the battery terminals and cable ends. They
should be clean and free of corrosion and dirt. 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 6.8). Make sure the cables and wires are
properly routed to avoid sharp edges, pinching,
and scuffing.

■ Hydraulic System
Hydraulic power is supplied from an engine driven
variable displacement piston pump.
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 escaping
hydraulic fluid, seek medical attention at
once.
The hydraulic reservoir is behind the door on the
left side of the turntable.
❑
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 6.9).

Not all hydraulic fluid is suitable to use in the
h y d r a u l i c s y s t e m . S o m e h a v e p o o r
lubricating characteristics 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.
❑ 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
Inspect all hydraulic hoses, tubes, and fittings for
wear, leakage, or damage (refer to Figure 6.10).
Make sure the hoses are properly routed to avoid
sharp edges, kinking, and scuffing. Inspect the
tubes for dents or other damage that may restrict
fluid flow. Make sure all hoses and tubes are held
firmly in their support brackets.
