REFILLING AND USING DETERGENT
When using detergent, the adjustable nozzle
must be set on "−". Fill the tank with highly
degradable detergent.
RECOMMENDED CLEANING PROCEDURE
Dissolve dirt by applying the detergent mixed
with water to the surface while still dry.
When dealing with vertical surfaces work from
the bottom upwards. Leave the detergent to
act for 1-2 minutes but do not allow the sur-
face to dry. Starting from the bottom, use the
high pressure jet at a minimum distance of 30
cm. Do not allow the rinse water to run onto
unwashed surfaces.

CLEANING THE NOZZLE
Disconnect the lance from

dirt deposits from the
nozzle hole using the tool.
