Maintenance
Lubrication
The air valve is lubricated at the factory to operate without
additional lubrication. If you want to provide additional lubri-
cation, remove the hose from the pump air inlet and add two
drops of machine oil to the air inlet every 500 hours of opera-
tion 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 com-
patible 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 connec-
tions are tight and leak-free.
Check fasteners. Tighten or retorque as necessary. Al-
though pump use varies, a general guideline is to retorque
fasteners every two months. See Torque Sequence, page
30.
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.
