Maintenance
Air Valve Lubrication
The air valve is designed to operate unlubricated, how-
ever if lubrication is desired, every 500 hours of opera-
tion (or monthly) remove the hose from the pump air
inlet and add two drops of machine oil to the air inlet.
Flushing
Insert suction tube into cleaning solution. Open air regu-
lator to supply low pressure air to the pump. Run the
pump long enough to thoroughly clean the pump and
hoses. Close the air regulator. Remove the suction tube
from the cleaning solution and drain pump. Place suc-
tion tube in the fluid to be pumped.
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Flushing schedule will be based on what
the pump is being used for. Use a compatible cleaning
solution and always cycle the pump during the entire
flushing process.
Always flush the pump and relieve the pressure before
storing it for any length of time.
Tightening Connections
Before each use, check all hoses for wear or damage,
and replace as necessary. Check to be sure all connec-
tions are tight and leak-free.
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 fail-
ure.
NOTICE
Do not over-lubricate the pump. Oil is exhausted
through the muffler and could contaminate your fluid
supply or other equipment. Excessive lubrication also
can cause the pump to malfunction.
