OPERATING MANUAL 

5. Set-up

The spray gun is designed specifically for AirCombi spraying, i.e. the Spray gun can be used in Airless mode 

as well as in Mixed Air mode. The atomization is accomplished by the pressure (adjustable from 0 up to 200 

Bar) through a pump. The air is used to improve the atomization quality and to increase or decrease the fan 

size by adjusting the proper fan regulator placed on the spray gun 

WARNING: INJECTION HAZARD POSSIBLE. DO NOT SPRAY WITHOUT TIP IN PLACE.  AL-

WAYS ENGAGE TRIGGER LOCK BEFORE REMOVING, REPLACING OR CLEANING TIP.  NEVER 

TRY TO CLEAN THE TIP WITH YOUR FINGERS.

To prevent hazardous concentration of toxic and/or flammable vapors, spray only in a prop

tive fluid hoses. Ground the spray gun through connection to a properly grounded fluid supply hose and 

pump.

5.2.   Assembling the spray nozzle

Warning: 

the proper nozzle size is essential for a good atomization on which depends the final result. The 

nozzle size is determinated by the coatings used and the type of application. Ask to the coatings’ manufac

turer for the proper tip size. 

1. Place the trigger lock in horizontal position in order to prevent accidental injection

WARNING: Before each nozzle change, assure to release the pressure in the spray gun and disconnect air 

supply.

2. Unscrew the nut

3. Remove the air cap

4. Remove the nozzle into the air cap

5. Place the nozzle into the air cap

6. Place the air cap complete with the nozzle into the spray gun

7. Screw the nut onto the spray gun

5.3   Spray Gun Filter

We suggest always to use a Gun Filter, unless the coatings used do not require it.  The mesh size of the gun 

filter is determinated by the nozzle size. See the table at page 10 for the suggested filter size.
