Flushing:
1. Have two pails ready; one for flushing fluid and one for waste.
2. If you are using latex paint, fill the flushing pail with approximately 1 gallon of warm soapy
water. For oil based paints, use approximately 1 gallon of mineral spirits.
3. Place the siphon hose in the “flushing” pail and the bleed tube in the “waste” pail.
4. Flip open prime valve lever (Ref # 60) to fully opened position, Or on older models turn
knob counter-clockwise to fully open position
5. Lower the pressure setting by turning the pressure control knob (Ref # 78) all the way
counter-clockwise.
6. Plug unit in outlet.
7. Turn unit on and slowly increase the pressure until the unit starts to run and “flushing” fluid
begins to exit the bleed hose.
8. Turn off unit and close the prime valve by flipping lever to closed position, or on older
models turn knob clockwise to fully closed position.
9. Place bleed hose back onto the siphon hose assembly.
10. Disengage gun trigger lock and trigger gun into waste container.
11. Start unit and trigger gun into the waste container until “flushing” fluid appears.
12. Move gun to “flushing” pail and resume triggering gun into pail. Re-circulate fluid for
approximately one to two minutes. Turn unit off.
13. Re-open the prime valve. Turn unit on and allow the “flushing” fluid to re-circulate through
bleed valve for approximately one minute. Turn unit off.
14. When spraying latex paint, repeat the “flushing” procedures with clear water. When
spraying oil based paints continue with “Priming” instructions.

4. Flip open prime valve lever (Ref # 60) to fully opened position. Or on older models turn
counter-clockwise fully to open position.
5. Lower the pressure setting by turning the pressure control knob (Ref # 78) all the way
counter-clockwise
6. Turn unit on and slowly increase the pressure until the unit starts to run and paint begins
to exit the bleed hose.
7. Close the prime valve by flipping back to closed position, or on older models turn knob
clockwise to fully closed position .
8. Place bleed hose back onto the siphon hose assembly.
9. Disengage gun trigger lock and trigger gun into waste container.
10. Start unit and trigger gun into the waste container until paint appears. Stop.
11. Move gun to the paint pail and resume triggering gun into pail. Re-circulate fluid for
approximately one to two minutes.
