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
Only follow these instructions when using water-
i
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.
Figure 18 - Cleaning the Spray Gun
1. Make sure the pump is switched OFF (O). Make sure the
PRIME/SPRAY knob is turned to PRIME. Unplug the sprayer.
2. Remove spray gun from the paint hose using adjustable
wrenches.
3. Unclip the trigger guard (a) from the filter housing (b) by
pulling outward from the filter housing. Unscrew the filter
housing.
4. Remove the filter (c) from the spray gun housing and clean
with the appropriate cleaning solution (warm suds for water-
soluble materials, solvents with a flash point of over 21°C for
solvent-based substances).
5. Remove spray tip (d) from spray guard assembly. Clean spray
tip with a soft-bristled brush and the appropriate cleaning
solution. Be sure to remove and clean the washer (e) and
saddle seat (f) located in the rear of the spray tip assembly.
6. Replace the cleaned filter, tapered end first, into the gun
housing. The tapered end (g) of the filter must be loaded
properly into the gun. Improper assembly will result in a
plugged tip or no flow from the gun.
7. Install spray tip (d), saddle seat (f) and washer (e), and replace
spray guard assembly.
8. Thread the spray gun back onto the paint hose. Tighten with
a wrench.
Figure 19 - Long-Term Storage
1. Remove hopper. Pour approximately two ounces of light
household oil into the inlet valve (a).
2. Remove hose from spray hose port. Place a rag over the spray
hose port, and turn the switch ON (l). Let the unit run for five
seconds. Turn the pump OFF (O).
3. Replace the hopper.
4. Wipe entire unit, hose and gun with a damp cloth to remove
accumulated paint. Replace the spray hose.
5. Push handle lock to collapse the handle.
