– 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.

Adjusting the Spray Pattern (see figure F)



Never actuate the trigger switch 9 while adjusting the 
air cap 2.

– Loosen the union nut

.

– Turn  the  air  cap 

2

 to the requested position.

– Firmly retighten the union nut.

Adjusting the Spraying Capacity (see figure G)

– To adjust the requested spraying capacity, turn the thumb-

wheel 

5

:

I

: Min. spraying capacity,

IIII

: Max. spraying capacity.

Adjusting the Air Flow (see figure H)

– Turn control knob 

16

 to adjust the air flow and the pres-

sure for the spray material being used. 

It is recommended to start with the maximum air flow.

Transport

The filled spray gun or a closed container with spray material 
can be placed in the set-down port 

17

 for transport. The hold-

ing fixture retains the spray gun firmly in the set-down port.

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 

8

 and empty the remaining spray 

material back into the original spray material.
