WARNING: Turn off the electrostatic voltage and ground the
gun electrode before performing the following tasks. Failure to
observe this warning could result in a severe shock.
NOTE: Depending on your system’s operation, you may not need to
perform this procedure every day. If you regularly perform color changes
with a powder feed center, the spray gun will be purged internally each
time a color change is performed. If this is the case, perform this
procedure every 2–3 days.
See Figure 4-2.
1. Disconnect the powder feed hose from the powder pump. Blow the
powder out of the powder feed hose and gun with an OSHA-approved
low-pressure air gun. Never blow air through the powder feed hose
from the gun into the powder pump.
2. Unscrew the nozzle nut (5).
3. Pull the nozzle (4) off the spray gun with a slight twisting motion.
4. Pull the electrode support (3) straight out of the spray gun (1). The
powder feed tube (2) will come out with the electrode support.
5. Clean all parts with a low-pressure air gun. Wipe the parts with a
clean, dry cloth.
6. Carefully remove fused powder from the parts with a wooden or
plastic dowel or similar tool. Do not use tools that will scratch the
plastic. Powder will build up and impact-fuse on scratches.
NOTE: If necessary, use a cloth dampened with isopropyl or ethyl
alcohol to clean the powder path parts. Remove the O-rings before
cleaning the gun parts with alcohol. Do not immerse the spray gun in
alcohol. Do not use any other solvents.
7. Inspect the powder path parts for wear. Replace worn parts.
CAUTION: Do not overtighten any threaded parts.
Overtightening threaded parts may result in stripped threads or
cracked parts.
