MACHINE PREPARATION
24. DETERGENT REGULATION (VERSION WITHOUT 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. In the first few metres, check that
the quantity of solution is sufficient to wet the floor, but not so much that it goes beyond the splash guard.
The amount of detergent released can be adjusted by turning the lever (1): turn it clockwise to reduce the
flow and anticlockwise to increase it. If turned fully to the right the flow of detergent is stopped. Bear in
mind that the correct amount of solution is always depends on the nature of the floor, the degree of dirt
and the forward speed.
25. 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 upper knob (2) clockwise. The
quantity of solution varies from a minimum of 30 litres/hour to a maximum of 75 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, working endurance with a full tank (about 48 litres) and the selector
(2) on 30 is about 1.5 hours.
2.
Regulate the percentage of liquid detergent in the solution by rotating the lower 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.
WARNING: If the CDS system fails to work, or you want to clean without using this device, operate the tap
(4) fitted to the brush head near the motor, turning the lever 180° as shown in the figure. Also turn the
knobs (2) and (3) anticlockwise, to the “OFF” position.
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.
26. RECOVERY
TANK
Make sure the recovery tank is empty, otherwise empty it completely.
Check the cap of the drainage tube (1) (on the rear of the machine) is correctly closed.
Check that the drain pipe cap (2) at the rear of the machine is correctly closed.
