by pushing in and twisting until it stops (fig 25).
Using detergent feature
• Maximum cleaning is achieved 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 surface to dry.
Starting from the bottom, use the high pressure jet
at a minimum distance of 30cm. Do not allow the
rinse water to run onto unwashed surfaces.
• After use, return the detergent tank to its storage
location (fig 21).
