– Avoid interruptions within the spray surface.
Guiding the spray gun evenly will provide uniform surface
quality.
Non-uniform clearance and spray angle lead to heavy forma-
tion of paint mist and thus to an uneven surface.
– End the spraying procedure outside the target area.
Never completely empty the container for the spray material
by spraying. If the suction tube is no longer immersed in the
spray material, the spray jet will be interrupted and this will
result in an inconsistent surface.
When coating material builds up on the nozzle and air cap,
clean both parts with the corresponding solvent.

Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull the mains
plug.
Cleaning (see figures I–K)
Proper cleaning is the requirement for flawless operation of
the spray gun. Improper or lack of cleaning voids warranty
claims.
Always clean the spray gun and the container with the respec-
tive diluting agent (paint thinner or water) for the spray mate-
rial being used.
Never immerse the complete spray gun into the cleaning
agent.
Never clean the nozzle and air holes of the spray gun with
pointed metal objects.
Do not pour diluted spray material back into the original spray
material drum/tin for storage.
Clean the spray gun thoroughly after having sprayed material
hazardous to one's health.
– Switch the base unit off and pull the trigger switch
9
of the
spray gun so that the spray material can flow back into the
container.
– Unscrew the container

and empty the remaining spray
material back into the original spray material.
