A clean state is the best method of ensuring operation wi-
thout 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
coating material used.
• Secure the spray gun
, refer to the operating manual of
the spray gun.
Remove and clean the tip.
• Unit with suction system
1. Open relief valve
valve position (circulation) and switch on unit
2. Remove suction tube from the material container, the re-
turn tube remains over the material container.
3. Immerse the suction system into a container filled with a
suitable cleaning agent
4. Turn the pressure control valve back in order to set a mini-
mal spraying pressure.
5. Close relief valve,
valve position (spraying)
6. Pull the trigger guard 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 con-
tainer (if appropriate, increase the pressure at the pressu-
re control valve slowly in order to obtain a higher material
flow).
The container must be earthed in case of
coating materials which contain solvents.
Caution! Do not pump or spray in container
with small opening (bunghole)!
See safty regulations.
7. Open relief valve
valve position (circulation)
8. Pump suitable cleaning agent in the circuit for several mi-
nutes.
with inflexible suction system (tube) step 9 up to 17
9. Screw the spray gun to the suction tube with both enclo-
sed 22 mm wrenches.
10. Pump a suitable cleaning agent in the circuit for about
1 minute.
11. Pull the trigger guard of the spray gun and lock it with a
clamp.
12. Close relief valve,
valve position (spraying)
13. Clean the suction tube about 3 minutes long.
14. Rinse in the circuit – Open relief valve
valve position (circulation).
15. Close the spry gun.
16. When cleaning with water repeat the procedure about 3
minutes long with clear water.
17. Remove spray gun from suction tube, close spray gun
connection at suction tube with closure nut.
The cleaning effect is increased by alterna-
tively opening and closing the spray gun.
18. Close relief valve,
valve position (spraying)
19. Pump the remaining cleaning agent into an open contai-
ner until the pump is empty.
20. Switch off the unit
Warm water improves the cleaning effect in
the case of water-dilutable coating materials.
• Unit with upper hopper
1. Open relief valve
valve position (circulation) and switch on unit
2. Turn the pressure control valve back in order to set a mini-
mal spraying pressure.
3. Close relief valve,
valve position (spraying)
4. Pull the trigger guard of the spray gun in order to pump
the remaining coating material from the hopper, 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).
