MAINTENANCE AND INSPECTION
It is important to establish a preventive maintenance and inspection program. Maintenance must be performed
at regular intervals to ensure efficient, dependable performance of the pump.
Maintenance should be performed in a dust-free area by a qualified technician. Any electrical work MUST be
performed by a qualified electrician.
DANGER
To prevent personal injury, ALWAYS depress the DUMP switch to release the pressure from the system, then DISCONNECT
the pump from the power supply before performing any maintenance or inspection procedure.
Keep the outer surfaces of the pump as free from dirt as possible.
Keep all hose connections free of dirt and grime.
Keep the breather hole of the oil filler cap clean and unobstructed at all times.
Keep all accessories that are connected to the pump clean.
Make sure that all unused quick-disconnect couplers are sealed with a protector cap.
NOTE
If applicable, check that the seals of the quick-disconnect couplers are not broken or worn. If seals are broken or worn, replace
them according to section 0.
Inspect the hydraulic hose and power cord for signs of wear after every eight hours of use. If
necessary, replace the hose.
If the power cord is damaged or wiring is exposed, replace or repair the power cord immediately.
Make sure that all voltages are wired for clockwise rotation.
A preventive maintenance and inspection program should include all of the procedures in sections 6.1 through
6.5.
