- In the first 2 seconds after machine start-up, the display (51) indicates the machine working hours (51-A) and the type of batteries installed (51-B).
NOTE Check the battery charge level. When the display shows at least one segment of the battery symbol (51-C) which is on but not flashing, the machine is ready for use. When the battery symbol (51-C) shows just one segment flashing, the batteries have to be charged (see the procedure in Maintenance chapter).
- Drive the machine to the working place, by starting it with both hands on the steering wheel (1) and by pressing the drive pedal (2). The drive speed can be adjusted from zero to maximum speed according to the pressure on the drive pedal (2).
- The forward/reverse gear is selected with the relevant lever (49) which is at the right of the steering wheel.
NOTE The driver’s seat (12) is equipped with a safety sensor, which allows the machine to be driven by pressing the pedal (2) only when the operator is on the driver’s seat.
NOTE The machine is equipped with an anti-skid safety system (display icon (51-J)) that reduces the speed when turning and when the machine tilts laterally, irrespectively of the pressure on the pedal. In this case, the reduction of speed is not a malfunction but a characteristic that improves the machine stability and safety in every condition.
Stopping the machine
- Stop the machine by releasing the drive paddle (2). It is not necessary to lock the machine during stopping or parking, because the electromagnetic brake on the wheels turn on automatically when the drive pedal is not pressed.
- Turn off the machine by pressing the push-button (42), then removing the user key (52).
NOTE The machine is running without the user key (52) in the key reader (41), it automatically switches off after 10 seconds of complete idle.
NOTE If the machine is on but not working, it automatically turns off after 5 minutes.
Machine operation (scrubbing/drying)
- Start the machine as shown in the previous paragraph.
- Press the One-Touch push-button (43) to lower the brush deck (7) and the squeegee (13) and start scrubbing and drying.
- Start scrubbing, by starting it with both hands on the steering wheel (1) and by pressing the drive pedal (2) as necessary.
NOTE The machine is equipped with a safety system that turns on the brush and vacuum system only when the machine is moving.
- Adjust the solution flow by pressing the push-button (47) as necessary, depending on the type of cleaning to be performed.
NOTE For the first 3 flow levels (Fig. 4), the amount of solution dispensed is automatically adjusted according to the machine speed, in order to obtain a constant amount of solution per linear meter of cleaning. Level 4 (when enabled) supplies the maximum possible quantity of detergent solution, regardless of the machine speed (to enable or disable this, see the Supervisor key section in the Maintenance chapter). The level 0 closes the solution flow completely.
Solution flow levels shown in Fig. 4:
- Level 1: 0.077 fl oz/ft (0.75 cl/m)
- Level 2: 0.15 fl oz/ft (1.5 cl/m)
- Level 3: 0.31 fl oz/ft (3.0 cl/m)
- Level 4: 0.74 gal/min (2.8 l/min)
- Level 0: OFF
- If necessary, to reduce the noise, turn on the vacuum system mute function by pressing the push-button (44).
NOTE For correct scrubbing/drying of floors at the sides of the walls, Advance suggests to go near the walls with the right side of the machine as shown in figure 5.
- To stop scrubbing/drying, press the One-Touch push-button (43) and wait for the brush deck (7) to lift. After 10 seconds, the vacuum system turns off too and the squeegee (13) lifts.
Adjusting of detergent concentration in the washing water
(For machines with EcoFlex system)
The system for mixing the detergent in the washing water is automatically activated when the brush is running. The percentage of detergent added to the washing water is set to level 1 (Fig. 6). By pressing the push-button (46), it is possible to set the percentage level to 2, or reset it to level 0. The set percentages are shown on the display (51-G).
As printed on the Fig. 6 screens: Level 1 shows 0.25% and 1:500, Level 2 shows 0.80% and 1:125, Level 0 is OFF. (The factory setting for level 1 in the parameter table on page 22 is printed as 0.25 % (1:400).)
EcoFlex system
Use the EcoFlex lever (50) when a temporary stronger washing power is needed. With the EcoFlex system activated, increased solution flow, activation of the extra pressure of the brush and an increase in the solution detergent concentration (level 2 if the level was set to 1 - level 1 if the level was set to 0) is obtained. By using the EcoFlex lever (50) again, the original settings are restored.
NOTE If the lever (D) is not used once again, the original settings are restored automatically after 60 seconds.
NOTE All of the above solution flow and detergent concentration values are factory settings. To change these settings, see the Supervisor key section in the Maintenance chapter.
Working with brush extra pressure function turned on
If the floor proves to be particularly difficult to clean, it is possible to turn on the brush extra pressure function, according to the following procedure:
- Press the One-Touch push-button (43) to lower the brush deck as shown in “Starting The Machine” paragraph.
- Press and hold the One-Touch push-button (43) for more than 1 second. The extra pressure function activation is shown by LED which turns from green to red, and by the icon shown below on the display (51).
- To return to normal pressure, press and hold the One-Touch push-button (43) for more than 1 second.
- To lift the brush deck without returning to the normal pressure, press the One-Touch push-button (43) and release it immediately.
Battery discharge during operation
When there is only one segment turned on and flashing on the battery symbol (51-C), it is advisable to charge the batteries, because the residual autonomy will last for a few minutes (depending on battery characteristics and work to be performed). When the battery symbol (51-C) is flashing and no segment is turned on, the battery autonomy is over. After a few seconds, the brush is automatically tuned off, while the vacuum system and the drive system stay on, to finish drying the floor and drive the machine to the appointed recharging area.
NOTE In case the machine drive system cannot be used in order to move the machine, see Pushing/Towing The Machine paragraph.
Tank emptying
An automatic float shut-off system (28) turns off the vacuum system when the recovery tank (17) is full. The vacuum system deactivation is signalled by a sudden increase in the vacuum system motor noise, and the floor is not dried.
When the recovery tank (17) is full, empty it according to the following procedure.
Recovery tank emptying
- Lift the brush deck and the squeegee by pressing the One-Touch push-button (43).
- Drive the machine to the appointed disposal area.
- Turn off the machine with the push-button (42) and remove the user key (52).
