The water from the lance comes in
squirts. The HP hose vibrates.

Unscrew all 6 valves, one after the other
(hexagonal brass screws, 3 in a row,
vertically and horizontally)
Take out valve body (with green or red
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.

under running water.
Do not forget the O-ring during
reassembly!
