PREVENTIVE MAINTENANCE
Internal Cleaning and Flushing
Preventive maintenance on the RWA-EMF spray guns
is basically limited to the cleaning and flushing of the
guns. Cleaning includes wiping the excess paint from
the exterior of the gun and the spray head. Flushing
the gun will keep the fluid passages clear. Flushing
may be accomplished through the spray nozzles or
dump valve. In any method, after using a solvent
to flush the gun, the fluid passages should then be
flushed with heated DI-water [130 °F to 140°F (54°C
to 60 °C)] and amine mixture.
> Solvents used for equipment flushing must
have flash point ratings equal to or greater than
the flash point rating of the coating material.
Solvents used for general cleaning must have
flash point ratings higher than 100 °F (37.8°C).

!
> An electrical discharge or spark may create an
electrical and/or fire hazard during maintenance.
Do not clean or service the spray gun with the
power supply on. Verify that the power supply
has been turned OFF to ground.
> Unexpected robot movement can be hazard-
ous. Do not adjust or repair the spray gun when
the robot is operating or waiting to start. The
robot must be taken out of service.
> Follow all Lockout/Tagout procedures prior
to entering to service the applicator. OSHA 29
C CFR 1910.147.

!
> Due to the design of this applicator, if
spraying with solvent based materials, use
the appropriate solvent recommended by
the material supplier.
NOTE
DI-water should only be used with waterbase ma-
terials.
External Cleaning
> Solvents used for external cleaning
should be non-polar. Non-polar solvents
leave the surface being cleaned non-con-
ductive and will not cause voltage tracking
to ground along cleaned surfaces.
