cleaning your Spray Gun
It is very important to clean your HVLP spray gun thoroughly
after each use.
1. Empty the spray material from the cup.
2. Pour a small amount of the appropriate solvent in the cup
and attach the cup to the spray gun.
3. Shake and spray the gun in a well ventilated area.
NOTE: Do not restrict the nozzle when cleaning. Back
flushing of the system is not necessary.
4. Repeat the steps above until the solvent appears clear.
5. Wipe the interior/exterior of the cup and the spray gun with
the appropriate solvent until it is clean.
6. Remove the needle, fluid nozzle, and air cap and clean
them thoroughly. Make sure that the air holes and
material passages are completely clean. Never use metal
tools or picks to clean the air cap or nozzle.
IMPORTaNT: any attempt to remove the fluid inlet fitting
will result in damage to the gun body and void the warranty.
NOTE: Remove the needle packing only when replacing
with a new needle packing. Do not remove the
needle packing for cleaning.
7. Disassemble, clean, and dry the check valve and air tubes
after each use.
IMPORTaNT: DO NOT clean the air tubes with hot solvents
such as lacquer thinner. hot solvents will damage the air tubes.
NOTE: Lubricate all of the threaded parts on the spray
gun with petroleum jelly when you put them
back together. This will help keep them working
properly.
IMPORTaNT: Do not use any lubricants containing silicone.
Silicone can cause problems when used with some paints.

4. Loosen the packing nut slowly
until the needle moves freely
back into position in the
nozzle.
Once you have adjusted the nut,
reconnect the air hose and the cup
assembly. Squeeze the trigger to see
if the leaking has stopped. If it has
not, make sure the packing nut is as
tight as possible, while allowing the
needle to move freely. If adjusting
the packing nut does not stop the
leak, replace the packing.
