Do not overreach with the high pressure hose or move the
pressure washer by pulling the hose, this could cause the ma-
chine to become unstable and fall over.
Do not kink or drive a motor vehicle over the high pressure
hose. Do not expose the high pressure hose to sharp edges or
corners.
Never use a roto nozzle to clean motor vehicles.
Working advice for cleaning with detergents
 Only use cleaning agents suitable specifically for high
pressure washers.
We recommend that you use detergent sparingly for the sake
of the environment. Observe the recommended dilution on
the detergent label.
Recommended cleaning method
Step 1: Loosening dirt
Remove the nozzle from the lance to give a low pressure flow
and spray on the detergent sparingly.
Step 2: Removing dirt
Spray off the loosened dirt with the high-pressure spray.
Note: When cleaning a vertical surface spray off dirt/deter-
gent from the bottom and work in an upwards direction. Rinse
from the top and work downwards.
