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.
• Secure the spray gun, refer to the operating manual of
the spray gun.
Remove and clean the tip and tip guard.
1. Open relief valve
valve position (circulation) and switch on unit
2. Remove suction system from the material container.
The return 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
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 container
(if appropriate, increase the pressure at the pressure con-
trol valve slowly in order to obtain a higher material flow).
When using multiple-gun operation the trigger guards
must be pulled in succession, in order to increase the
cleaning performance.
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 safety regulations.
