special note of the accompanying booklet
"Safety Instructions for High-Pressure Clean-
ers" No. 5.951-949.
Use of the cleaner
Use this appliance exclusively
– for cleaning operations with low-pressure
jet and detergent (e.g. cleaning of ma-
chines, vehicles, buildings, tools),
– cleaning with high-pressure jet without
detergent (e.g. cleaning facades, terraces,
gardening equipment).
For stubborn dirt we recommend the dirt
blaster as an optional accessory (for HD ...
Plus included in the delivery).
Safety features
Overflow valve with pressure
switch
On reducing the flow rate with the pressure
