Check For Fluid Leakage; Clean The Cabinet - Graco 333013B Instructions - Parts Manual

Maintenance
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 dam-
aged. Scratches in the air cap or
spray tip or a damaged electrode
can distort the spray pattern.
7. Wipe off the parts with a dry cloth. Be careful not to
damage the electrode.
To reduce the risk of fire, explosion, or electric
shock, never operate the gun with a damaged
electrode.
8. Check the electrode (25a). Replace if damaged.
9. Check the condition of the spray tip gasket and
install the spray tip in the aircap, page 23.
10. Install the spray tip and air cap/tip guard, shroud,
and retaining ring, page 23. Be sure the electrode
(25a) is in place.
11. Test Gun Resistance, page 29.

Check for Fluid Leakage

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.
To reduce the risk of an injury, follow the Pressure
Relief Procedure when you stop spraying and
whenever you are instructed to relieve the pressure.
During operation, periodically check all openings of the
gun shroud (ZZ) for the presence of fluid. See F
19. 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. Discharge the system voltage, relieve the pres-
sure, then remove the gun for repair.

Clean the cabinet

• Inspect the cabinet and clean up any spilled paint.
Conductive paint residue allowed to contact
grounded parts may short out the electrostatics.
• Keep the inside of the cabinet clean, for proper
operation.
• Inspect the door T-handle locking screw regularly,
to ensure the threads are well greased. Apply sili-
cone-free grease to the threads when necessary.
• Visually inspect the ground strip (240) for damage.
Replace if needed. Measure the resistance weekly.
See Test Ground Strip Resistance, page 30.
