Check for Fluid Leakage
During operation, periodically check all openings of the
gun shroud (ZZ) for the presence of fluid. See F
IGURE
12. Fluid in these areas indicates leakage into the
shroud, which could be caused by leaks at the fluid tube
connections or fluid packing leakage.
If fluid is seen in these areas, stop spraying immedi-
ately. Relieve the pressure, then remove the gun for
repair.

NOTICE
Do not use metal tools to clean the air
cap/tip guard or spray tip holes as this
could scratch them, and make sure
the electrode is not damaged.
Scratches in the air cap or spray tip or
a damaged electrode can distort the
spray pattern.
To reduce the risk of fire, explosion, or electric shock,
never operate the gun with a damaged electrode.

If any fluid leakage from the gun is detected, stop
spraying immediately. Fluid leakage into the gun
shroud could cause fire or explosion and result in
serious injury and property damage.
