CLEANING THE UNIT
A clean state is the best method of ensuring operation with-
out problems. After you have finished spraying, clean the unit.
Under no circumstances may coating material rests dry and
harden in the unit. The cleaning agent used for cleaning (only
with a flash point above 21 °C) must be suitable for the coat-
ing material used.
Warm water improves the cleaning effect in
the case of water-dilutable coating materials.
•
Secure the spray gun, refer to the operating manual of
the spray gun.
Remove and clean the tip and tip holder.

Unit with suction system
1. Set pressure relief valve to
2. Switch the device on (Pos. I) using the ON/OFF switch.
3. Remove the suction system from the material container.
The return pipe hose remains over the material container
until barely any coating material comes out.
4. Immerse the suction system into a container filled with a
suitable cleaning agent
5. Turn the pressure control valve back in order to set a mini-
mal spraying pressure.
6. Set pressure relief valve to
7. Pull the trigger of the spray gun in order to pump the
remaining coating material from the suction hose, high-
pressure hose and the spray gun into an open container (if
appropriate, increase the pressure at the pressure control
valve slowly in order to obtain a higher material flow).
The container must be earthed in case of
coating materials which contain solvents (e.g.
by using a metal container).
Caution! Do not pump or spray in container
with small opening (bunghole)!
See safety regulations.
8. Set pressure relief valve to
9. Pump suitable cleaning agent in the circuit for several
minutes.
The cleaning effect is increased by alterna-
tively opening and closing the spray gun.
10. Set pressure relief valve to
11. Pump the remaining cleaning agent into an open contain-
er until the pump is empty.
12. Set pressure relief valve to
13. Switch the unit off using the ON/OFF switch (Pos. 0).

Unit with upper hopper
1. Set pressure relief valve to
2. Switch the device on (Pos. I) using the ON/OFF switch.
3. Turn the pressure control valve back in order to set a mini-
mal spraying pressure.
4. Set pressure relief valve to
5. Pull the trigger of the spray gun in order to pump the re-
maining coating material from the hopper, high-pressure
hose and the spray gun into an open container (if appro-
priate, increase the pressure at the pressure control valve
slowly in order to obtain a higher material flow).
The container must be earthed in case of
coating materials which contain solvents (e.g.
by using a metal container).
Caution! Do not pump or spray in container
with small opening (bunghole)!
See safety regulations.
6. Fill up hopper with suitable cleaning agent.
7. Set pressure relief valve to
8. Pump suitable cleaning agent in the circuit for several
minutes.
9. Set pressure relief valve to
10. Pump the remaining cleaning agent from the hopper,
high-pressure hose and the spray gun into an open con-
tainer
11. Set pressure relief valve to
12. Switch the unit off using the ON/OFF switch (Pos. 0).
