Battery discharge during operation

Until the green warning light (81a) stays on, the batteries allow the machine to work normally.

When the green warning light (81a) turns off, and the yellow warning light (81b) turns on, 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 red warning light (81c) turns on, the autonomy is over. After a few seconds, the brush/pad-holder is automatically tuned off, while the vacuum system and (only for SCRUBTEC 653BL, SCRUBTEC 651BCL, SCRUBTEC 661BL) the drive system stay on, to finish drying the floor and drive the machine to the appointed recharging area.

WARNING!

Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.

TANK EMPTYING

An automatic float shut-off system (36) turns off the vacuum system when the recovery tank (21) is full.

The vacuum system deactivation is signalled by a sudden increase in the vacuum system motor noise frequency, and the floor is not dried.

CAUTION!

If the vacuum system turns off accidentally (for example, when the float is activated because of a sudden machine movement), to resume the operation: turn off the vacuum system by pressing the switch (73), then open the cover (22) and check that the float inside the grid (36) has gone down to the water level. Then close the cover (22) and turn on the vacuum system by pressing the switch (73).

When the recovery tank (21) is full, empty it according to the following procedure.

Recovery tank emptying

1.Stop the machine.

2.Lift the brush/pad-holder deck by pressing the pedal (11).

3.Lift the squeegee (25) with the lever (10).
