Shut off air supply to paint tank and release pressure in the tank.
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 tightly over the air cap
opening(s) and pull the trigger. Air will back up through 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.
When blowing out the hose, the open end should be aimed away
from any person to avoid blowing solvent into the eyes or on the skin
causing possible injury.
To prevent damage to the fluid tip of fluid needle, be sure to either:
1) pull the trigger and hold while tightening or loosening the fluid tip,
or 2) remove fluid needle adjusting screw to relieve spring pressure
against needle collar.
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.
1) Remove the fluid control assembly.
2) Pull the needle assembly out approximately 1-1/4”
3) Loosen the needle cap.
4) Screw the needle assembly locknut out for more trigger movement, in for less trigger
movement.
5) 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.
6) Tighten the needle cap.
Over tightening may damage the threads, which will make future
adjustments difficult.
7) Reassemble.
1) Check and replace any damaged O-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.
1) When not in use, turn the fluid adjustment knob counterclockwise to open and reduce the
spring tension on the needle fluid tip.
2) Spray gun must be cleaned and lightly lubricated prior to storage.
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.
Never use lubricants containing silicone as these lubricants can
cause finish defects.
Apply light machine oil to: fluid needle packing, air valve packing, side port control packing and
trigger point. Coat fluid control spring and all threaded connections with petroleum jelly prior to
storage.
