NOTE
For correct scrubbing/drying of floors at the sides of the
walls, Clarke suggests to go near the walls with the right
side of the machine (A and B, Fig. 19) as shown in the
figure.
CAUTION!
To avoid any damage to the floor surface, turn off the
brushes/pad-holders when the machine stops in one
place, especially when the extra pressure function is
on.
Detergent flow adjustment
(For machines with Chemical Mixing System)
1.
Turn the knob (A, Fig. 20) clockwise or counter-clockwise to
increase or decrease the detergent concentration.
2.
The average detergent concentration values, matching the 4
colored areas of the scale (B), are shown in the figure.
3.
To set the detergent quantity to zero, fully turn the knob (A)
counter-clockwise.
NOTE
The detergent concentration is kept constant even if the
washing water flow is changed with the switches (C) or
(D).
Working with brush/pad-holder extra pressure function
turned on
If the floor proves to be particularly difficult to clean, it is
possible to turn on the brush/pad-holder extra pressure
function by pressing the pedal (E) to position (E3).
CAUTION!
When the cylindrical brush deck (S, Fig. 2 - Page 9) is
installed, the extra pressure function is not enabled.
