Operation
ATTENTION
Dry running of more than 2 minutes leads to damage of
the high-pressure pump. If the appliance does not build
up pressure within 2 minutes, switch the appliance off
and proceed in accordance with the instructions in
Chapter "Troubleshooting".
High pressure operation
CAUTION
Keep a distance of at least 30 cm when using the jet for

Car tyres, paint or sensitive surfaces such as wood
should not be cleaned with the dirt blaster, as there is a
risk of damage.
