Handling the high-pressure hose

Cleaning the unit (shutting down)

Avoid sharp bending or kinking of the high-pressure hose. The 

smallest bending radius amounts to about 20 cm.

Do not drive over the high-pressure hose. Protect against sharp 

objects and edges.

The unit is equipped with a high-pressure hose specially suited 

for piston pumps.

  1.  Open the relief valve, valve position PRIME

 (k circulation).

  2.  Switch the unit OFF.

  3.  Turn the pressure control knob counterclockwise to 

minimum pressure.

  4.  Pull the trigger of the spray gun in order to release the 

pressure from the high-pressure hose and spray gun.

  5.  Secure the spray gun, refer to the operating manual of the 

spray gun.

  6.  If a standard tip is to be cleaned, see Page 17, Section 

12.2.

 

  If a non-standard tip is installed, proceed according to the 

relevant operating manual.

  7.  Depending on the model, leave the suction tube or the 

suction hose and return hose immersed in the coating 

material or swivel or immerse it into a corresponding
