Use different sprayheads for different part shapes. Select the
appropriate nozzle for the parts being coated.
S
Pinpoint nozzles for penetration
S
8-orifice nozzles for flat surfaces
S
Cylindrical nozzles for general purpose coating
Angle the nozzles to meet and follow the parts as they move through the
booth. Typical nozzle-to-part distance is 20 − 25 cm (8 − 10 in.). Coat the
inside surfaces and recessed areas first, then coat the outside surfaces
and open areas.
Perform the following maintenance procedures daily.
WARNING: Make sure the gun is grounded before spraying
powder or cleaning the gun with compressed air. Without a
ground connection the gun will become electrostatically
charged. Personnel touching the gun could receive a shock.
1. Remove the powder feed hose from the pump and the air tubing from
the pump and diffuser. Use an OSHA-approved air gun to clean the
hose, diffuser, and charge module with compressed air.
2. Remove the diffuser from the gun body. Disassemble the diffuser and
clean the parts with compressed air and a clean, soft cloth. Check
the powder contact parts for wear and replace worn parts.
NOTE:
Never use a knife or other sharp objects to clean plastic
parts. Powder will build up on scratches on the powder contact
surfaces. The powder particles can fuse on impact and clog the gun.
3. Blow out the charge module and sprayheads. Disassemble and
clean the charge module. Check the powder contact parts for wear
and replace worn parts.
NOTE: Never blow powder through the feed hose back into the
pump. Turn on the booth exhaust fan, disconnect the hose from the
pump, and blow out the hose from the pump end into the booth.
WARNING: All electrically conductive equipment in the spray
area must be grounded. Ungrounded or poorly grounded
equipment can store an electrostatic charge which can give
personnel a severe shock or arc and cause a fire or explosion.
4. Make sure all conductive equipment in the spray area, including the
guns, are connected to a true earth ground. The resistance from part
to ground, through the hangers and conveyor, must not exceed one
megohm. For best results, the resistance should be less than 500
