Preparing to Paint
Before painting, it is important to make sure that the fluid in the
system is compatible with the paint that is going to be used.
NOTE: Incompatible fluids and paint may cause the valves
to become stuck closed, which would require
disassembly and cleaning of the sprayer's fluid
section.
ImPOrTaNT: always keep the trigger lock on the spray gun in
the locked position while preparing the system.
1. Place the siphon tube into a container of the appropriate
solvent. Examples of the appropriate solvent are water for
latex paint or mineral spirits for oil-based paints.
2. Place the return hose into a metal
waste container.
3. Set the pressure to minimum by
turning the pressure control knob
to the "MIN" setting.
4. Move the PRIME/SPRAY valve
down to the 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.
5. Turn on the sprayer by moving the ON/OFF switch to the ON
position.
6. Allow the sprayer to run for 15–30 seconds to flush the old
solvent out through the return hose and into the metal waste
container.
7. Turn off the sprayer by moving the ON/OFF switch to the OFF
position.
NOTE: make sure that the spray gun does not have a tip or
tip guard installed.
8. Move the PRIME/SPRAY valve up to
the SPRAY position.
9. Turn on the sprayer.
10. Unlock the gun by pushing the gun
trigger lock to the unlocked position.
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.
11. Trigger the gun into the metal waste container until the old
solvent is gone and fresh solvent is coming out of the gun.
12. Lock the gun by pushing the gun trigger lock to the locked
position.
13. Set down the gun and increase the pressure by turning the
pressure control knob slowly clockwise.
14. Check the entire system for leaks. If leaks occur, follow the
"Pressure Relief Procedure" in this manual before tightening
any fittings or hoses.
15. Follow the "Pressure Relief Procedure" in this manual before
changing from solvent to paint.
Be sure to follow the pressure relief procedure when
shutting down the sprayer for any purpose, including
servicing or adjusting any part of the spray system,
changing or cleaning spray tips, or preparing for
cleanup.
