Small repairs - do it yourself!
The water from the lance comes in
squirts. The HP hose vibrates.
Proceeding:
Unscrew all 6 valves, one after the other
(hexagonal brass screws, 3 in a row,
vertically and horizontally)

plastic coating) and O-ring by means
of needle nose pliers. Check O-ring for
damage. In case of a damage the O-ring
has to be replaced.
Take a wire (paper clip) and clean valves
under running water.
Do not forget the O-ring during
reassembly!

Irregular jet from nozzle.
