Figure 14 - Practice
1. Be sure that the paint hose is free of kinks and clear of objects
with sharp cutting edges.
2a. If you are spraying thicker materials, turn the PRIME/SPRAY
knob to MAX SPRAY.
2b. If you are spraying thinner or lighter bodied materials, turn the
PRIME/SPRAY knob to SPRAY (1).
i
The paint hose should stiffen as material begins to flow
through it.
3. Unlock the spray gun.
4. While pointing the gun at a piece of scrap wood or cardboard,
trigger the spray gun to bleed air out of the hose.
5. When material reaches the spray tip, spray a test area to check
the spray pattern.
6. Use the lowest pressure setting necessary to get a good spray
pattern (A). If the pressure is set too high, the spray pattern
will be too light. If the pressure is set too low, tailing will
appear or the paint will spatter out in blobs rather than in a
fine spray (B).
Figure 15 - Unclogging the Spray Tip
If the spray pattern becomes distorted or stops
i
completely while the gun is triggered, follow these
steps.
Do not attempt to unclog or clean the tip with your
finger. High pressure fluid can cause injection injury.
Danger
1. Release the trigger and lock the gun off. Rotate the reversible
tip arrow 180º so that the point of the arrow is toward the rear
of the gun (see figure 15).
Under pressure, the spray tip may be very difficult to
i
turn. Turn the PRIME/SPRAY knob to PRIME and
trigger the gun. This will relieve pressure and the tip
will turn more easily.
2. Turn the prime/spray knob to spray.
3. Unlock the gun and squeeze the trigger, pointing the gun at
a scrap piece of wood or cardboard. This allows pressure in
the spray hose to blow out the obstruction. When the nozzle
is clean, material will come out in a straight, high pressure
stream.
4. Release the trigger and lock the gun off. Reverse the tip so
the arrow points forward again. Unlock the gun and resume
spraying.
Cleanup
If you are using water-soluble materials, use warm suds
i
to clean the spray device. If you are using solvent-
based spray, use a suitable solvent for cleaning, with a
flash point of over 21°C.
Do not use solvents for water-soluble materials, as the
i
mixture will turn into a gel-type substance which is
difficult to remove.

Figure 16 - Short Term Cleanup
i Only follow these instructions when using water-
soluble materials. If you are using solvent-based spray,
follow the Cleanup and Long-Term Storage steps.
A) Shutdown
1. Perform the Pressure Relief Procedure (see figure 7) and
unplug the sprayer.
2. Pour 1/2 cup water slowly on the top of the paint to prevent
the paint from drying.
3. Wrap the spray gun assembly in a damp cloth and place it in
a plastic bag. Seal the bag shut. Place the sprayer in a safe
place out of the sun for short-term storage.
B) Startup
1. Remove the gun from the plastic bag. Stir the water into the
paint.
2. Turn the PRIME/SPRAY knob to PRIME.
3. Plug sprayer in.
4. Turn the switch to ON (I).
5. Turn the PRIME/SPRAY knob to MAX SPRAY. Test the sprayer
on a practice piece and begin spraying.
Figure 17 - Flushing the System
1. Perform Pressure Relief Procedure (see figure 7).
2. Empty the hopper of spraying material (see figure 8).
3. While removed, rinse the hopper with the appropriate
cleaning solution until clean.
4. Lock the gun and remove spray tip assembly. Replace the
hopper and return tube. Fill the hopper with appropriate
cleaning solution.
5. Place a waste container (a) next to the original material
container (b). The containers should be touching. Aim the
spray gun into the side of the original material container (b)
and hold the trigger.
6. While pulling the gun trigger, turn the pump ON (l), and
turn the PRIME/ SPRAY knob to SPRAY (1) to purge material
from the hose back into the original container. Keep holding
trigger through next steps.
7. When cleaning solution flows from the spray gun, keep
holding the trigger and aim the spray gun into the side of the
waste container (ground gun with a metal container if flushing
with flammable solvent).
8. Trigger the gun until the fluid flowing out of the gun is clear.
You may need to dispose and obtain new cleaning solution.
9. Turn the PRIME/SPRAY knob to PRIME and trigger gun to
relieve pressure.
10. If hopper is empty of all cleaning solution, refill with new
cleaning solution.
11. Turn the PRIME/SPRAY knob to PRIME, and turn the pump ON.
12. Let the pump circulate the cleaning solution out the return
tube for 2-3 minutes. Turn the pump OFF.
13. Remove and thoroughly rinse the hopper once more.
14. Replace the hopper for storage.
