Filter Cleaning/Checks – Vario Nozzle Cleaning
Unscrew the adapter on the water supply connection and
pull out the filter sieve by narrow, flat pliers. Rinse the filter
sieve with water and insert it back in. A damaged sieve
needs to be replaced.
ATTENTION! Under no circumstances put the high-
pressure cleaner into operation if the filter sieve is
damaged or missing.
Use a thin wire to clean the Vario nozzle or to remove
potential obstructions. See below.
