CLEANING THE UNIT
A clean state is the best method of ensuring operation wi-
thout problems. After you have fi nished 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 fl ash 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 fi lled 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 
fl ow).
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 infl exible 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 eff ect 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 eff ect 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 fl ow).
