MACHINE PREPARATION
26. REGULATING THE DETERGENT WITH THE CDS SYSTEM
1.
Regulate the flow of detergent solution to the brushes by rotating the upper knob (1) 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, work autonomy with a full tank (about 85 litres) and the selector (1) on
30 is about 3 hours.
2.
Regulate the percentage of liquid detergent in the solution by rotating the lower knob (2) 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.
ATTENTION: In case of failure of the CDS system, or if you want to work without this device, you can
act on the tap (3) mounted on the brush head near the motor.
ATTENTION: before regulating the solution, check there is detergent in the inner can, and that the side
water tap is turned on. To avoid any tampering with the set regulation, you can remove the two rubber
knobs that command the two switches and cover the two holes with the plastic caps supplied with the
machine.
To resolve any malfunctioning of the CDS system, contact the COMAC assistance centre.
ATTENTION: Placing the tap lever in this way, the FSS dosing system is excluded and the detergent
solution will be expelled and fall on the brushes. Rotate the knobs (2) and (3) anticlockwise, to the “0”
position.
ATTENTION: Placing the tap lever in this way there will be no leakage of detergent solution on the
brushes. Rotate the knobs (2) and (3) anticlockwise, to the “0” position.
ATTENTION: Placing the tap lever in this way the FSS dosing system is active.
27. POTENTIOMETER ADJUSTMENT
Proceed as follows to adjust the forward speed with the potentiometer:
1.
Check that the potentiometer knob is placed on minimum.
2.
Check that the brush head and squeegee are lifted off the ground
3.
Turn the key operated master switch to “ON”.
4.
Engage the dead man's levers on the handlebars, so the machine starts to move
5.
Adjust the desired forward speed by turning the knob gradually clockwise
WARNING! The reverse speed was reduced compared to that of forward
speed in order to comply with existing safety at work standards.
If the potentiometer is adjusted while reversing, the adjustment of the
forward speed will be automatically changed.
