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.

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,

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.
