Running down of the batteries during work:
To avoid damaging the batteries and shortening their working life, do not continue
using the machine once the batteries are flat.
The meaning of the battery charge control light (fig. A, ref. 5) is given below:
1 flashing red LED: battery voltage under 18 V (ACID batteries) or under 19 V (GEL
batteries), drive is shut down. Recharge the batteries.
1 red LED on steadily: battery voltage between 18 and 20.5 V (ACID batteries) or 19 and
21.5 V (GEL batteries), SUPER-MINIMUM battery charge. Recharge the batteries.
1 red LED + 1 yellow LED on steadily: battery voltage between 20.5 and 21.5 V (ACID
batteries) or 21.5 and 22.5 V (GEL batteries), MINIMUM battery charge.
1 red LED + 1 yellow LED + 1 green LED_1 on steadily: battery voltage between 21.5
and 24 V (ACID batteries) or 22.5 and 25 V (GEL batteries), MEDIUM battery charge.
1 red LED + 1 yellow LED + 1 green LED_1 + 1 green LED_2 on steadily: battery
voltage between 24 and 27.4 V (ACID batteries) or 25 and 28.4 V (GEL batteries),
MAXIMUM battery charge.
Each time you fill the solution tank, always empty the collection tank.
When the collection tank is full, the level indicator comes on (fig. A, ref. 11) and after a few
seconds the suction motor is switched off: stop working and empty the tank.
Emptying the collection tank:
1 Stop the machine by releasing the pedal (fig. B, ref. 7)
2 Turn off all functions using the brush button (fig. A, ref. 8).
3 Take the machine to the disposal area.
4 Empty the collection tank through the hose (fig. B, ref. 10), then rinse the
tank with clean water.
Emptying the solution tank:
5 Proceed as described in points 1 to 3.
6 At the end of work, empty the solution tank by by unscrewing the cap (fig.
E, ref. 4), then rinse the tank with clean water.
before lifting the solution tank, always remove the suction hose fitted to the squeegee.
When washing the collection tank, never remove the suction filter (fig. G, ref. 1) from
its housing and never direct the jet of water against the filter itself.
You are then ready to wash and dry again.
