Maintenance
Lubrication
The air valve is lubricated at the factory to operate
without additional lubrication. If you want to provide
additional lubrication, remove the hose from the pump
air inlet and add two drops of machine oil to the air
inlet every 500 hours of operation or every month.
CAUTION
Do not over-lubricate the pump. Oil is exhausted
through the muffler, which could contaminate your
fluid supply or other equipment. Excessive lubrication
can also cause the pump to malfunction.
Flushing and Storage
Flush the pump 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 you store it for any length of time.
Read Pressure Relief Procedure
on page 10.
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 29.
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.
