• Truck hydraulic flow should be within the volume range
shown in Specifications, Section 5.1 .
• Hydraulic fluid supplied to the Sideshifter must meet
the requirements shown in Specifications, Section 5.1.

Tools Required

In addition to a normal selection of hand tools, the
following are required:
• 20 GPM (80 L/min) inline flow meter.
(Cascade Flow Meter Kit, part no. 671477).

Troubleshooting Chart

3.1-3
Determine All The Facts – It is important to gather all the
facts about the problem before beginning any service
procedures. The first step is to talk to the equipment
operator. Ask for a complete description of the malfunc-
tion. Guidelines below can then be used as a starting
point to begin troubleshooting.
Sideshift Circuit
• Attachment will not sideshift.
• Attachment sideshifts slowly.
To correct these problems, see Section 3.3.

WARNING: Before servicing any hydraulic
component, relieve pressure in the Attach-
ment system. Turn the truck off and move
the truck auxiliary control handle several
times in both directions.
After completing any service procedure, always test
the Attachment through several cycles. First test the
Attachment empty to bleed any air trapped in the
system to the truck tank. Then test the Attachment
with a load to be sure it operates correctly before
returning to the job.
Stay clear of the load while testing. Do not raise the
load more than 4 in. (10 cm) off the floor while testing.
