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.
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 30.
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 10.
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Use a compatible solvent.
Always flush the pump and relieve the pressure before
storing it for any length of time.
