Maintenance
Lubrication
Flushing and Storage
Flush the pump often enough to prevent the fluid you
are pumping from curing, drying, or freezing in the pump
and damaging it. Follow the Pressure Relief Procedure
on page 10 before storing it for any length of time. Use a
compatible flushing fluid.
Tightening Threaded
Connections
1. Before each use, check all hoses for wear or dam-
age, and replace as necessary.
2. Check to be sure all threaded connections are tight
and leak-free.
3. Check and re-torque all screws and fasteners at
least every two months.
Preventive Maintenance
Schedule
• Establish a preventive maintenance schedule,
based on the service history of the pump. This is
especially important for prevention of spills or leak-
age due to diaphragm failure.
CAUTION
Lubrication of the pump is not required. Oil is
exhausted through the muffler, which could contami-
nate the fluid supply or other equipment. Excessive
lubrication can also cause the pump to malfunction.
