Proper way to trigger the spray gun
Keep stroke
even
Start stroke Pull trigger
Overlap each stroke by about 30%. This will ensure an even
coating.
When you stop painting, lock the gun trigger lock, turn the
pressure control knob counterclockwise to its lowest setting and
set the PRIME/SPRAY valve to PRIME. Turn the ON/OFF switch
to the OFF position and unplug the sprayer.

Practice

1. Be sure that the paint hose is free of kinks and clear of
objects with sharp cutting edges.
2. Turn the pressure control knob counterclockwise to its to
its lowest setting.
3. Move the PRIME/SPRAY valve to the SPRAY position.
4. Turn the pressure control knob clockwise to its highest
setting. The paint hose should stiffen as paint begins to
flow through it.
5. Unlock the gun trigger lock.
6. Trigger the spray gun to bleed air out of the hose.
7. When paint reaches the spray tip, spray a test area to
check the spray pattern.
8. Use the lowest pressure setting
necessary to get a good spray
pattern. 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 gobs rather than in a fine
spray.

cleanup

Special cleanup instructions for use with
flammable solvents:
• Always flush spray gun preferably outside and at least one
hose length from spray pump.
• If collecting flushed solvents in a one gallon metal
container, place it into an empty five gallon container, then
flush solvents.
• Area must be free of flammable vapors.
• Follow all cleanup instructions.
IMPoRtant: the sprayer, hose, and gun should be cleaned
thoroughly after daily use. Failure to do so permits material
to build up, seriously affecting the performance of the unit.
always spray at minimum pressure with the gun
nozzle tip removed when using mineral spirits or
any other solvent to clean the sprayer, hose, or
gun. Static electricity buildup may result in a fire
or explosion in the presence of flammable vapors.
1. Follow the "Pressure Relief Procedure" found in the
Operation section of this manual.
2. Remove the gun tip and tip guard and clean with a brush
using the appropriate solvent.

3. Place the siphon tube into a container of the appropriate
solvent (refer to recommendations of the material
manufacturer). An example of the appropriate solvent is
water for latex paint.
4. Place the return hose into a metal waste container.
5. Move the PRIME/SPRAY valve to its
PRIME position.
note: hold the return hose in the waste
container when moving the PRIMe/
SPRay valve to PRIMe in case the
sprayer is pressurized.
6. Move the engine ON/OFF switch to the ON position and
start the engine.
7. Turn on the sprayer by
moving the sprayer ON/OFF
switch to the ON position.
8. Slowly turn the pressure
control knob clockwise to
increase the pressure until
fluid starts to come out of the
return hose.
9. Allow the solvent to circulate
through the sprayer and flush
the paint out of the return
hose into the metal waste container.
10. Turn the pressure control knob fully counterclockwise to its
lowest setting.
11. Turn off the sprayer by moving the ON/OFF switch to the
OFF position.
12. Move the PRIME/SPRAY valve to its
SPRAY position.
13. Turn on the sprayer.
14. Turn the pressure control knob slowly
clockwise to increase pressure.
Ground the gun by holding it
against the edge of the metal
container while flushing. Failure to
do so may lead to a static electric
discharge, which may cause a fire.
15. Trigger the gun into the metal waste container until the
paint is flushed out of the hose and solvent is coming out
of the gun.
16. Continue to trigger the spray gun into the waste container
until the solvent coming out of the gun is clean.
note: For long-term or cold weather storage, pump
mineral sprits through the entire system.
17. Follow the "Pressure Relief Procedure" found in the
Operation section of this manual.
18. Store the sprayer in a clean, dry area.
IMPoRtant: Do not store the unit under pressure.

cleaning the Spray tip

1. Flush the gun with solvent immediately after the work is
completed.
2. Oil the sliding pins to prevent them from seizing up.
Should the spray tip become clogged, reverse the
spray tip with the lever and pull the trigger. Once
the obstruction comes out of the spray tip, release
the trigger, reverse the spray tip back to the spray
pattern setting, and resume spraying.
Do not attempt to clean the tip with
your finger.
Do not use a needle or other sharp pointed
instrument to clean the tip. the hard tungsten
carbide is brittle and can be chipped.
