Before each use, squirt one drop of oil onto the lower
pivot point (J) of the pump (33). See Fig 5.
For very short shutoff periods, relieve pressure, leave
the suction tube in the paint and clean the front of the
spray tip.
Check the packing nut/wet cup (38) before each use
and periodically when in use. Follow the Pressure Relief
Procedure Warning before checking or tightening. The
packing nut should only be tight enough to stop
leakage. Do not over tighten. Overtightening may cause
binding and excessive wear on the packings.
Clean the outlet filter often and whenever the sprayer is
stored. On the last workday of the week, flush all the
paint out of the sprayer. See “Flushing Guidelines,’ on
page 9. If you are using a paint that will dry overnight,
flush the sprayer daily at shutdow’h.
Always push the suction tube onto the clip (13) on the
side of the frame (6) and wrap the hose around the
sprayer when storing it, even if only overnight, to help
protect the hose from damage.
Do not store the sprayer with water in it. Even for over-
night storage, you should fill the sprayer with mineral
spirits. This prevents rust and greatly extends the life of
the sprayer.
CAUTION
Do not let water freeze in the pressure control or
pump in cold weather. Freezing could cause a
change in the pressure control calibration or strip-
ping of gears, resulting in loss of pressure or
stallina.

Once a month, lubricate the needle bearing (36) in the
displacement rod (34); use a grease gun to apply the
grease to the grease fitting (35). See Fig 5.
Periodically, or if the motor overheats, unplug the
power supply cord, follow the Pressure Relief Pro-
cedure Warning on page 10, and clean all paint and dirt
off the motor. Change the gearcase oil at least once a
year, using Grace Gear Oil no. 206-230. The gearcase
holds 3 pints (1.4 liters). Don’t use hypoid grease.
