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, always test
the Clamp through several cycles. First test the
Clamp empty to bleed any air trapped in the system to
the truck tank. Then test the Clamp 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.
