Setting the water quantity

Adjust the water quantity using the regulating button according to the dirt on the floor covering.

Note:
Carry out initial cleaning attempts with low water volume. Increase water volume step-by-step until the desired cleaning result is achieved.

Setting the Vacuum Bar

Oblique position

To improve the vacuuming result on tiled floors the vacuum bar can be turned to an oblique position of up to 5°.

Loosen the wing nuts.
Turn the vacuum bar.
Tighten the wing screws.
Inclination
If the vacuum result is unsatisfactory the in-clination of the straight vacuum bar can be modified.
Adjust the rotary handle to incline the suction bar.
Height
The bend of the suction lips upon contact with the floor is influenced with the height adjustment.
Try adjusting the twist handles of the height adjustment until the best vacu-uming result is achieved.

Cleaning

ATTENTION
Risk of damage to the floor covering. Do not operate the appliance on the spot.

Insert the end of the extension cable as a loop in the strain relief clamp.
