PRIMING WITH THE SUCTION EXTENSION
• The time needed to prime will vary from 30 seconds
to 3 minutes depending upon the thickness of the
material you are spraying.
• Thinning the material will speed up the prime time
and will also increase the material flow rate.
However, never exceed the thinning
recommendations as listed on the container for the
material you are using.
• Using the suction extension will decrease the
material flow, so it will take longer to apply the same
amount of material to the surface being sprayed.
• If your sprayer is properly cleaned and oiled and it
takes longer than three minutes to prime, your
piston and/or pump housing may be worn and will
need to be replaced before using your suction set.
If you are using the suction extension, you will need to prime the
sprayer by removing air from the system. To prime:
1. Turn the flow knob fully counterclockwise to maximum.
2. Make certain the sprayer is plugged in.
3. Hold the sprayer below the level of the paint. This will
speed up the priming.
4. Squeeze the trigger and hold until all air is out of the
system and material is flowing freely out of the sprayer tip.
This should take about two minutes.
CAUTION
The suction set must remain completely submerged in the
material. If it is not completely submerged and air is
sucked into the system, the piston could seize. If the
piston seizes, the sound the gun makes will change to a
low hum and the gun will quickly become hot to the touch.
Never run the sprayer when the piston is seized. Should
this happen, clean the piston and the piston housing
thoroughly using the cleanup procedures found in this
manual.
SPRAYING
CAUTION
If material is leaking from the threads between the spray tip
and the locking nut, turn off the sprayer immediately or the
sprayer could be damaged.
The sprayer will leak from behind the spray tip if the swirl valve
is not seated properly. If you notice material leaking from this
area:
1. Unplug the sprayer immediately.

2. Remove the spray tip by turning it counterclockwise.

3. Remove the swirl valve and see if it needs to be cleaned or
replaced (see page 8). Also check the pump housing opening
for any dirt or other obstruction and clean if necessary.
4. Put the swirl valve
back in place, making
sure it can seat
properly without any
obstruction.
5. Thread on the spray
tip by turning it
clockwise and tighten
firmly by hand.
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.
NOTE: 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 (look in
ACCESSORIES for part number).
NOTE: When spraying, make sure your fluid container
is at least half-filled with material. A container
low on fluid will cause the sprayer to spit and
will spray a poor pattern.
HOW TO SPRAY
Once you have acheived a good spray pattern on your test
piece of wood or cardboard, it is time to begin spraying your
work. The key to a good job is an even coating over the entire
surface. This is done by using even strokes (follow the TIPS,
below).
TIP: Keep your arm moving at constant speed and
keep the sprayer at a constant distance from
the surface. The best spraying distance is 10
to 14 inches between spray tip and the
surface.
Even coat throughout
Keep stroke smooth and at an even speed.
