Maintenance
Lubrication
If your system includes an automatic air line lubricator,
adjust the lubricator as instructed in the separate
instruction manual.
For manual lubrication, each day, remove the air inlet
hose and place 12 to 15 drops of high quality, light
motor oil in the inlet. Reattach the hose and turn on the
air to blow the oil into the motor.
Throat Packing Adjustment
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Once a week, or after each 40 hours of operation,
check the tightness of the throat packing nut. It should
be tight enough to stop leakage, but no tighter.
To check, first relieve the pressure. Then, remove the
identification plate (M) from the motor. Using a spanner
wrench or a 0.22 in (5.6 mm) diameter rod, adjust the
nut. Reinstall the identification plate before operating
the pump. See Fig. 3.
Flushing
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
To reduce the risk of injection injury, static sparking, or
splashing in the eyes or on the skin, relieve the pres-
sure. Then, remove the spray tip (spray guns or spray
valves only) before flushing. Hold a metal part of the
gun/valve firmly to the side of a grounded metal pail
and use the lowest possible fluid pressure during
flushing.

Corrosion Protection
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
CAUTION
Water, or even moist air, can cause your pump to
corrode. To help prevent corrosion, never leave the
pump filled with water-based fluid or air. After normal
flushing, flush the pump again with mineral spirits or
oil-based solvent, and relieve the pressure. This
leaves the mineral spirits in the pump.
