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.
Cleaning the Filter
Clean the filter with a brush dipped in solvent. Never poke the
filter with a sharp instrument.

applied as shown below.
Cleaning the Hopper Screen
The screen at the bottom of the paint hopper may need
cleaning periodically. Check it every time you add paint.
Remove the screen by pulling it out of the hopper with a pliers.
Clean the screen with water or solvent and a soft-bristle brush,
if necessary.
Tightening the PRIME/SPRAY Knob
Sometimes the two allen screws holding the PRIME/SPRAY
knob outer cover will vibrate loose. This allows the cover to
turn without changing the valve setting. If this happens,
loosen the screw with a 1/16 allen wrench, turn the knob to
SPRAY and tighten the screw.
