Maintenance
Lubrication
Flushing and Storage
Flush the pump with a compatible solvent often enough
to prevent the fluid you are pumping from drying in the
pump and damaging it. Follow the
on page 10 before storing it for any length of
time.
Tighten 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. Re-torque the fluid cover
screws first, followed by the manifold screws.
NOTE:
Before using pump, loosen fluid cover
screws (31) 1-2 turns and then re-torque to 20 N•m
(15 ft-lb).
Preventive Maintenance
Schedule
Establish a preventive maintenance schedule, based on
the service history of the pump. This is especially impor-
tant for prevention of spills or leakage 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.
