Maintenance

Lubrication

The air valve is lubricated at the factory and designed to op-
erate without additional lubrication.

If added 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 exhausted
through the muffler, which could contaminate your fluid sup-
ply or other equipment.

Tightening Threaded Connections

Before each use, check all hoses for wear or damage, and
replace as necessary. Be sure all threaded connections are
tight and free of leaks.

Check fasteners. Tighten or retorque as necessary. Although
pump use varies, a general guideline is to retorque fasteners
every two months. See

Service

for torque specifications. See

Torque Sequence,

page 17, for torque sequence.

Flushing and Storage

Flush the pump to prevent the fluid from drying or freezing in
the pump and damaging it. Always flush the pump and

re-

lieve the pressure

before storing 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 7.

If you are flushing

, run the pump long enough to thoroughly

clean the pump and hoses, close the air regulator, and re-
move the suction hose from the solvent and place it in the
fluid to be pumped.

If you are shutting down the pump

, remove the suction hose

from the fluid container, run the pump until the fluid is forced
out of the system, and shut off the air supply immediately.
