Proper use

Use this high pressure cleaner exclusively for
– Cleaning using low pressure jet and de-
tergent (for e.g. for cleaning machines,
cars, buildings, tools),
– For cleaning using high pressure jet
without detergent (for e.g. for cleaning
facades, terraces, garden appliances).
For stubborn dirt, we recommend the use of
the dirt blaster as a special accessory.
DANGER

bottom cleaning therefore only on speci-
fied places with an oil trap.
