Maintenance
Lubrication
The air valve is designed to operate unlubricated,
however 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. Oil is exhausted
through the muffler, which could contaminate your
fluid supply or other equipment. Excessive lubrica-
tion can also cause the pump to malfunction.
Flushing and Storage
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 11.
Flush the pump when necessary to prevent the fluid
you are pumping from drying or freezing in the pump
and damaging it. Use a compatible solvent.
Before storing the pump, always flush the pump and
relieve the pressure.
Tightening Threaded Connections
Before each use, check all hoses for wear or damage,
and replace as necessary. Check to be sure all
threaded 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 32.
Tightening the Clamps
When tightening the clamps (111), apply thread lubri-
cant to the bolts and be sure to torque the nuts (113)
to 50 to 60 in-lb (5.6 to 6.8 NSm). See Fig. 9. See
Torque Sequence, page 32.

(5.6 to 6.8 NSm). See Torque Sequence, page 32.

Preventive Maintenance Schedule
Establish a preventive maintenance schedule, based
on the pump’s service history. This is especially impor-
tant for prevention of spills or leakage due to dia-
phragm failure.
