This Allied work tool is not self-powered and its
performance level will be impaired by a hydraulic
system that is not operating properly or set outside
the accepted specifications.
If the carrier machine is equipped with an adjustable
work mode switch, verify its proper setting for Skid-
Pac operation.
Use a flow meter to measure oil delivery and to verify
the cracking pressure of the relief valve. When
troubleshooting, include all parts associated with the
auxiliary circuit, including the hoses to exclude
possibility of a collapsed hose.
Tools required for testing include a flow meter and
pressure gages. Test procedures, along with a form
to record the results of the flow test, can be found in
the Technical Data section of this manual.
