the unit running until the water exits with no air
bubbles.

on.
Operating with high pressure

switch. The motor only starts up when the lever
on the handgun is pressed.

adjusted by means of the pressure control on
the spray lance.
• Always direct high-pressure jet at object being
cleaned from a greater distance first of all, in
order to prevent damage if pressure is too high
Dirt blaster: For stubborn dirt.
The jet rotates at high speed and achieves a
very high impact pressure so that it has a very
good cleaning effect. (Suction of cleaning agent
is not possible when using the dirt blaster.)

-lance. No detergent can be drawn in with a
high working pressure.

required position.
• Suspend the detergent hose in the detergent
container (not included).

recommend that you use detergents sparingly.

gents and other cleaning products, which gua-
rantee trouble-free operation of your cleaner.
Please ask for advice or send for our catalogue
