Fluid Level

Check the hydraulic reservoir fl uid level with the aerial

platform stowed on a level surface. The fl uid level must

be between the full and add marks as viewed on the

sight glass (refer to Figure 7.7).

Figure 7.7 – Fluid Level Indicator

Caution

Not all hydraulic fl uid is suitable to use in the hy-

draulic system. Some have poor lubricating char-

acteristics and can increase component wear. Only

use hydraulic fl uid as recommended.

If necessary, remove the fi ller cap and add fl uid of the

proper type. 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.

The sight glass on the reservoir has an internal thermom-

eter to measure the fl uid temperature. The temperature

should be less than 93°C (200°F).

Fluid Filter

Checking the condition of the hydraulic fl uid fi lter 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 fi ttings for wear,

leakage or damage (refer to Figure 7.8). Make sure the

hoses are properly routed to avoid sharp edges, kinking

and scuffi ng. Inspect the tubes for dents or other dam-

age that may restrict fl uid fl ow. Make sure all hoses and

tubes are held fi rmly in their support brackets.

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 7.6). Make sure the cables and

wires are properly routed to avoid sharp edges, pinching

and scuffi ng.

Hydraulic System

Hydraulic power is supplied from an engine driven vari-

able displacement piston pump.

Danger

Hydraulic fl uid escaping under pressure can have

enough force to inject fl uid into the fl esh. Serious

infection or reaction can result if medical treatment

is not given immediately. In case of injury by escap-

ing hydraulic fl uid, 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.
