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 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.
CAUTION
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.
CAUTION
DO NOT clean the air tubes with hot solvents such as
lacquer thinner. Hot solvents will damage the air tubes.

working properly.

Do not use any lubricants containing silicone. Silicone
can cause problems when used with some paints.

Maintenance

Perform the following maintenance procedures to keep your
HVLP spray gun working properly.

Adjusting the Packing Nut

If material leaks from around or through the packing nut,
readjust the packing nut.
1. Disconnect the air hose from the air inlet and remove the
cup assembly.
2. Pull the trigger all the way back and hold.
3. Tighten the packing nut using a 3/8 inch wrench until the
needle remains retracted inside the nozzle when you
release the trigger.
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.
Replacing the Needle Packing and Air
Valve Seals
NOTE: Remove the needle packing only when
replacing with a new needle packing. Do not
remove the needle packing for cleaning.
The needle packing and the air valve seals can
be replaced separately. If you are replacing
only one of them, use the appropriate steps
from the following procedures.
