TROUBLESHOOTING

RR0545.eps

3.5

Rotation Function

There are six potential problems that could affect the

ROTATE function:
• Incorrect load handling. Refer to the

Operator's Guide

(part no. 6892529)

for suggested procedures.

• Incorrect hydraulic pressure or flow from the lift truck.
• External leaks.

• Solenoid equipped –

Electrical circuit faults, defective

solenoid coil or valve.

• Worn/defective hydraulic rotator motor.
• Worn/defective drive box or rotation bearing assembly.

3.5-1

Supply Circuit Test

Check the pressure supplied by the truck at the carriage

hose terminal. Pressure must be within the range

shown in Specifications, Section 5.1.

PRESSURE TO

THE ATTACHMENT MUST NOT EXCEED 3500 psi

(250 bar).

Check the flow volume at the carriage hose terminal.

Flow must be within the range shown in Specifications,

Section 5.1.

Rotate clockwise (CW) or counterclockwise (CCW) to

the stops. Hold the lever in the ROTATE position for a

few seconds. Release the lever and check for external

leaks at fittings, hoses, revolving connection and valve.

Flow Meter

WARNING

: Before removing any hoses,

relieve pressure in the hydraulic system.

With the truck off, open the truck auxiliary

control valve(s) several times in both

directions.

3.5-2

Rotation Circuit Test without

Load

Solenoid equipped –

Press the solenoid button and

listen for a 'click' at the solenoid valve. If no sound

is heard, first check the fuse, wiring and coil. Make

sure that the solenoid valve is not jammed. Repair as

necessary, refer to Section 4.11.

IMPORTANT:

Solenoid operated valves must be

plumbed so that the solenoid is

not energized

during

the ROTATE function.

Turn the truck off. Connect a 5000 psi (345 bar) pressure

gauge to each rotator drive control valve fitting, as

shown.

Rotate the attachment without a load and note pressure

readings of both gauges.
• If the attachment rotates in one direction faster

than the other or rotates in one direction only, the

rotator drive control valve may need repair. Refer to

Section 4.7.

• If the lower gauge reading

exceeds

500 psi (35 bar),

there is excessive back pressure in the supply circuit.

Check for restrictions such as numerous fittings,

90 degree fittings or hose sizes less than No. 8.
