Maintenance
Lubrication
The air valve is designed to operate unlubricated.
If lubrication is desired, every 500 hours of operation
(or monthly), remove the hose from the pump air inlet
and add two drops of machine oil to the air inlet.
CAUTION
Do not over-lubricate the pump. Excess oil is ex-
hausted through the muffler, which could contami-
nate your fluid supply or other equipment.
Flushing and Storage
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Always flush the pump and relieve the
pressure before storing it for any length of time. Use
a compatible solvent.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
Tightening Connections
Before each use, check all hoses for wear or damage,
and replace them as necessary. Check to be sure all
connections are tight and leak free. Check fasteners.
Tighten or retorque as necessary. Although pump use
varies, a general guideline is to retorque fasteners
every two months. See Torque Sequence, page 25.
Preventive Maintenance Schedule
Establish a preventive maintenance schedule, based
on the pump’s service history. This is especially
important for prevention of spills or leakage due to
diaphragm failure.
