Regulating The Detergent In Models With Fss; Potentiometer Adjustment - Fimap Mx Series Use And Maintenance Manual

30. REGULATING THE DETERGENT IN MODELS WITH FSS

Adjust the maximum amount of water emission through the side tap (1).
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 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 (2) on 30 is
about 3 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.
ATTENTION: If the FSS system does not work, or you want to clean without using this device, you can
intervene on the tap (4) on the brush head near the motor, rotating the lever by 180° as shown in the
figure. Rotate the knobs (2) and (3) anticlockwise, to "OFF".
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 anomalies in the FSS system contact the FIMAP assistance service
ATTENTION: By positioning the tap lever in this way, the FSS dosing system is excluded and the
detergent solution is expelled onto the brushes. Rotate the knobs (2) and (3) anticlockwise, to the "0"
position.
ATTENTION: By positioning the tap lever in this way the detergent is not expelled onto the brushes.
Rotate the knobs (2) and (3) anticlockwise, to the "0" position.
ATTENTION: By positioning the tap lever in this way the FSS dosing system is on.

31. 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 "man present" 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.
