Operating breaks, cleaning, maintenance
Wearing parts such as material nozzle (7 to 10), air nozzle (3 to 6), material needle (39 or
40), material needle gaskets (21 and 29), guide ring (24) and other gaskets as well as
fastening components should be checked at appropriate intervals and replaced if necessary
(e.g. if the material needle does not close sufficiently or if there is uncontrolled discharge of
coating substance or air, or displacement of the automatic spray gun on the fastening
device).
Caution
Close the supply of control, circular jet and flat jet air as well as the material feed during
maintenance and repair work.
Notes
The automatic spray gun type RA-2 HV3 is never to be dismantled into its individual parts
except when this is necessary for repair or maintenance purposes. When cleaning and
during material change, the gun should be rinsed through using a detergent recommended
by the supplier of the coating substance until it is discharged clear.
The automatic spray gun RA-2 HV3 should never be completely immersed in detergent!
This could destroy the gaskets and rinse out the lubricant.
