1) All nozzles and needles are precision made and should be handled with care.

2) Except as described in “Fluid Needle Adjustment”, do not make any alterations in 

the gun. To do so will cause finishing difficulties.

3) To clean nozzles, soak them in solvent to dissolve any dried material, then blow 

them clean with compressed air.

4) Do not probe any of the holes in the nozzles with metal instruments. If probing is 

necessary, use only a tool that is softer than brass.

FLUID NEEDLE ADJUSTMENT

1) Loosen the needle cap.

2) Screw the needle assembly locknut out for more trigger movement, in for less 

trigger movement.

3) Adjust the needle assembly so that when the trigger moves, the air valve assembly 

moves 1/16” to 3/32” before the needle assembly moves.

4) Tighten the needle cap.

O-RINGS, SEALS, AND PACKING NUTS

1) Check and replace any damaged 0-rings and seals. O-rings and seals can be wiped 

clean but not soaked in solvent.

2) Unscrew packing nuts and replace the packing ONLY if a leak will not stop when 

the nut is tightened. Do not over tighten a packing nut as this will restrict 

movement of the needle.

3) Reassemble in reverse order of above and use light machine oil to lubricate 

moving parts.

STORAGE

1) When not in use, turn the fluid adjustment knob counter-clockwise to open to 

reduce the spring tension on the needle fluid tip.

2) Spray gun m

4) Clean gaskets with solvent soaked rag. To prevent damage, do not immerse gas-

kets or spray gun in solvents as this is detrimental to the lubricants and packings.

5) After using water to clean out water based paints or materials, spray mineral spirits 

through the gun to prevent corrosion.

6) Lubricate gun after cleaning using light machine oil.

1) Open the vent on the paint tank. If using an external mix cap, loosen cap slightly.

2) Reduce air pressure to 10 to 20 PSI. Hold a wadded piece of cloth over the tightly 

around the air cap opening(s) and pull the trigger. Air will back up thorough the 

fluid nozzle and force fluid out of the hose and back into the tank.

3) Pour paint from the tank and clean tank with solvent and rags.

4) Pour enough thinner into the tank to clean the hose and gun thoroughly. Close the 

tank and spray from the gun until the solvent comes out clean.

5) Remove fluid hose and blow it out thoroughly to remove all traces of solvent in the 

hose.
