2. Close the high pressure filter relief valve.
3. Immerse the spray material pump or the suction system in the spray material to be used for
working.
4. Place the high pressure filter return pipe in the tank. Then open the high pressure filter relief
valve.
5. Open the ball valve for the compressed air supply and use the pressure regulator to set the
compressed air supply to 1 bar. The material spray pump will now draw in the spray material.
The spray material flows back into the tank through the high pressure filter, the high pressure
filter relief valve and the return pipe.
6. Point the airless gun into the tank. Unlock the safety lever on the airless gun. Operate the air-
less gun take-off and close the high pressure relief valve. The spray material will now flow
through the high pressure filter, the spray material line and the airless gun, back into the tank.
7. Release the airless gun take-off and set the working pressure at the pressure control valve of
the pressure reducer.3
Before carrying out any coating work, we recommend a test spray (e.g. on to paper or wood). Only
if the test gives you the desired result should you start to coat the actual object.
Make sure that the edges and the fringe areas of the object to be coated are also given an even
coating.
5.6 WORK STOPPAGES
• If working with 2-K spray material, you must note the given pot life and follow it pre-
cisely. Within this time, the unit must be carefully cleaned and rinsed with the rec-
ommended solvent. There must be no residue left in the spray material pump, the
high pressure filters or the airless gun.
• When work is stopped, the safety lever of the airless gun must be locked.
For work stoppages of between 10 and 30 minutes, please proceed as follows:
Wear eye protection
1. Lock the safety lever on the airless gun.
2. Shut off the compressed air supply by closing the ball valve.
3. Briefly open the high pressure relief valve, taking care that the return pipe is not pointed at other
people or at yourself, until the pressure has reduced. Then close the high pressure relief valve
again.
4. Clean the outside of the airless nozzle from spray material residue.
