INTERNAL ROTATION CONTROL SYSTEM TROUBLESHOOTING

GUIDE

if equipped

The information contained in this guide provides for troubleshooting the Internal Rotation Control System only.

Any references to the attachment or the base machine will be made only to give some guidance as to where

a problem may exist. Any specifi c maintenance or troubleshooting information for the attachment or base
machine will need to be obtained from its respective maintenance manual.

To properly troubleshoot the Hydraulic Rotation Circuit the following tools and equipment are needed:

•

Hydraulic pressure gauge 0 - 5000 PSI range

•

Accumulator charge and test unit 0 - 1000 PSI range

•

Volt-Ohm meter

•

Standard blade screwdriver

•

Crescent wrench or similar tools for cover removal

•

3/16" Allen wrench

•

Test llght (optional)

SYMPTOM

PROBABLE CAUSE

REMEDY

1. Will not rotate

a. Faulty rotation motor

b. No fl ow to rotation motor - no fl uid in
accumulator

c. Faulty unloading valve

d. Operating pressure is too low

i. Check motor per manual

i. Check for fl ow out of ports A & B
ii. Check accumulator precharge pres-
sure; should be 650 PSI.

i. Check electrical power to the unloading
valve.
ii. Remove cartridge and check for con-

tamination.

i. Check pressure at the gauge “G” port,
which should be 2000-2500 PSI; adjust
pressure reducing valve if necessary.
