CAUTION
Do not cross-thread the locking nut. Make certain it is
threaded correctly before tightening. Make certain that the
pump housing is pushed far enough into the sprayer and
the locking nut is screwed on tightly.
6. Insert the swirl valve into the front end of the pump housing.
7. Place the spray tip onto the pump housing and turn it
clockwise until it is tightened securely.
LUBRICATING THE SPRAYER
NOTE: Lubricating your sprayer prior to storage is
important to prolong the life of the pump
housing components.
1. Turn the sprayer upside-down while the fluid container is
removed.
2. Pour a small amount of standard houshold oil into both the
intake and return openings on the pump housing.

3. Plug in the sprayer.
4. Squeeze the trigger of the sprayer for 2 to 3 seconds while
sprayer is still inverted as shown above. This works the
household oil onto the piston and swirl valve. The oil
protects the sprayer by keeping any extra material from
drying and seizing the piston.
5. Replace the suction set and thread the fluid container onto
the sprayer.

MAINTENANCE
Parts of your sprayer wear out with use and require regular
replacement. They include the swirl valve, piston and spring.
These parts are not covered by your sprayer warranty.
More abrasive materials such as latex paints and stains cause
these parts to wear out faster than less abrasive materials such
as oil-based paints and stains, thin stains and sealers.
REPLACING THE SWIRL VALVE
The swirl valve is shaped to cause the material to spin as it
comes out of the sprayer. The spinning breaks the material up
into a fine spray. As more material goes through the swirl valve,
it wears out the valve and the shape of the valve changes.
When it changes too much to produce a good spray pattern, the
valve needs to be replaced.

NOTE: The swirl valve that comes with your sprayer
has a clear base. It is to be used with latex
and oil-based paints only.
If you will be spraying lacquers, make sure to
use the optional swirl valve designed for
lacquers, available for purchase by calling our
toll free number. It has a grey base.
1. Make certain that the sprayer is unplugged.
2. Turn the spray tip counterclockwise and remove.

3. Pull the old swirl valve out of the pump housing and insert a
new one.
4. Place the spray tip over the new swirl valve and tighten it
securely by hand.
NOTE: Make sure to tighten all spray tips firmly by
hand. If the spray tip is not tightened firmly
enough, the sprayer could leak or the tip could
be damaged. Do not use a tool to tighten the
spray tip. If the tip is too tight, it may be
damaged.
