7. The spray gun should be triggered (turned off and on)
on each stroke. This will save paint and avoid paint
buildup at the end of the stroke. However, do not trigger
during the middle of a stroke. This will result in an
uneven spray and splotchy work. See Figure 10 for
proper triggering on a left-to-right stroke. Reverse for
a right-to-left stroke.
8. Move the spray gun at a rate of speed that is comfort-
able for you. If you have to move your arm too fast in
order to prevent excessive paint buildup, either (1)
lower the pressure by turning the pressure control knob
counterclockwise, or (2) use a spray tip with a smaller
hole. If you have to move your arm too slow in order to
get a good coating, either (1) raise the pressure by
turning the pressure control knob clockwise, or (2) use
a spray tip with a larger orfice. You should always keep
the spray gun moving when making a stroke. Slowing
down in one place will cause sags or runs.
CLEAN-UP
1. Turn power switch to OFF.
2. Bleed off any pressure remaining in the pump by
opening the dump valve.
3. Remove gun tip and clean with solution compatible
with material applied.
4. Remove paint container from its position directly below
siphon hose and paint strainer. Replace with a con-
tainer of solvent compatible with material being ap-
plied.
5. Turn the pressure control knob counter-clockwise to
the lowest pressure setting.
6. Turn power switch to ON.
7. Trigger spray gun(s) into container to flush pump, hose
and gun(s) clean.
8. Turn power switch to OFF.
9. Bleed off solvent.
10. Unplug unit and store in a clean dry area.
For long-term storage, be sure to flush unit with appropriate
oil before storing.
The pump, hose and gun should be
cleaned thoroughly after daily use.
CAUTION
Failure to do so permits material to cake, seriously affecting
the performance of the unit.
Figure 10. - Proper way to trigger spray gun.
9. Overlap each stroke by about 40% to 50%. The
overlap will assure a paint coating that is uniform
across the work. One way to get good overlap is to
point the spray gun at the edge of the last stroke.

WARNING
When cleaning the pump, hose
and gun with mineral spirits or any
other solvent, ALWAYS spray at minimum pressure with
the gun nozzle tip removed. Static electricity build-up may
result in a fire or explosion in the presence of flammable
vapors.
After daily use, paint should be flushed from the unit with
solvent compatible with the material applied, and then re-
flushed with mineral spirits.
