DETERGENT REGULATION (VERSION WITH CDS)
First, fully open the tap in the rear part of the machine by turning the lever (1) anticlockwise. Choose the
required work programme using the I-Drive device; press the accelerator pedal to operate the brushes, the
machine starts to move and the detergent solution starts to come out. During the first few metres make the
following adjustments:
1.
Regulate the flow of detergent solution to the brushes by rotating the left-hand knob (2) clockwise.
The quantity of solution varies from a minimum of 55 litres/hour to a maximum of 230 litres/hour, with
7 set measurement points. The right solution flow should be proportional to the degree of dirt on the
floor. In addition, remember that the time available for continuous working depends on the quantity of
water in the tank: For example, the work autonomy with a full tank (about 280 litres) and the selector
(2) set at 55, is about 4 hours
2.
Regulate the percentage of detergent in the solution by rotating the right-hand knob (3) clockwise.
The lower value is equal to 0.5% (for standard detergents) or 0.1% (for a concentrated detergent,
diluted as indicated on the label supplied with the machine), while the higher value is equal to 3.5% or
0.7%, with 7 set points. Use high detergent percentages to remove very greasy dirt from the floor
To avoid any tampering with the set regulation, you can remove the two switches and cover the two holes
with the plastic caps supplied with the machine.
WARNING: Verify that the tap lever (1) is fully open; the lever is located at
the rear of the steering column.
ATTENTION: before regulating the solution, check there is detergent in the inner can, and that the side
water tap is turned on.
To resolve any malfunctioning of the CDS system, contact the COMAC assistance centre.
WARNING: If the CDS system fails to function, or you want to work without this device, turn the lever of the
tap (4) - on the front right-hand side of the machine - clockwise. Also turn the knobs (2) and (3)
anticlockwise, to the “OFF” position.
