Determine All The Facts – It is important that all

talk to the equipment operator. Ask for a complete
description of the malfunction. The following
guidelines can then be used as a starting point to
begin troubleshooting procedures:
Sideshift Circuit

WARNING: Before servicing any
hydraulic component, relieve pressure in
the system. Turn the truck off and move
the truck auxiliary control valves several
times in both directions.
After completing any service procedure, 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.
