•Follow any warning s ckers and instruc onal s ckers on the HPU, as well as reading the manual.
•Ensure the HPU has a flow of 8-52GPM (30-196LPM) @ 2300-3500
PSI (158-241 Bar) and make sure the
system opera ng pressure is set between 1500 PSI to 3000PSI (103-206 Bar.) The normal pressure for most
applica ons is 2800 PSI.
•Ensure that the system opera ng pressure does not exceed 3300 PSI (227 Bar)
•Check pump inlets, make sure there is no debris inside.
•Always disconnect hydraulic lines before servicing pump
Make sure you follow any addi onal direc ons found in the manual for the power unit. Failure to do so
may result in equipment failure or injury. These instruc ons may not be applicable to non-FFP Power
Units.
