MACHINE PREPARATION
For example, the work autonomy with a full tank (about 60 litres) and the selector (1) set at 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: if the CDS system does not work, or you want to clean without using this device, you
can intervene on the tap (3) on the brush base near the motor, rotating the lever by 180° as shown in
the figure. Rotate the knobs (1) and (2) anticlockwise, to the “0” position.
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 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.
25. FORWARD SPEED ADJUSTMENT (FOR VERSIONS WITH TRACTION ONLY)
Adjust the forward speed, turning the knob (1) clockwise will increase the speed, turning it counter-
clockwise will decrease the speed.
Warning, any adjustment of the potentiometer will increase/decrease the speed in both directions.
If the speed is inadequate, the speed adjustment knob can be turned with the machine running; by
pressing the dead man's lever (2) the machine starts to move, check that the speed is adequate during
26. REVERSE FUNCTION (FOR VERSIONS WITH TRACTION ONLY)
To activate the reverse direction, just push the command levers (1) downwards.
With the base lowered, the brush continues turning but the solution supply is interrupted.
ATTENTION: when making even brief reverse movements, check the squeegee
is raised. For long stops, raise the base to avoid ruining the brushes
