Tank Emptying - Nilfisk BR 652 Instructions D'utilisation

ENGLISH
Working with brush extra pressure function turned on (only for BR 652, BR 752)
1. If the floor proves to be particularly difficult to clean, it is possible to turn on the brush/pad-holder extra pressure function by
pressing the push-button (65).
2. To return to normal pressure, press the push-button (65) again.
The push-button (65) is enabled only when the deck (10) is lowered and the LED (68) of the One-Touch push-button (67) is on.
CAUTION!
In case of brush motor overload, due to foreign bodies which prevent the brushes from turning or to excessively
aggressive floors/brushes, the safety system stops the brushes after about a minute of continuous overload.
The overload is shown by the three battery warning lights (62) flashing simultaneously.
If the overload takes place when the extra pressure function is on, the system automatically reduces the
pressure on the brushes, thus turning the extra pressure function off. If the overload persists, the brushes stop.
To start scrubbing again after a brush stop due to overload, stop the machine by turning the ignition key (58) to
"0". Turn on the machine by turning the ignition key (58) to "I".
Battery discharge during operation
1. Until the green warning light (62) stays on, the batteries allow the machine to work normally.
When the green warning light turns off and first the yellow warning light then the red warning light turn on, the batteries must
be charged.
• When the yellow warning light turns on the machine residual autonomy will last for a few minutes (depending on the
characteristics of the battery).
• When the red warning light turns on the machine autonomy is over: after a few seconds the brushes are automatically
stopped and the deck is automatically lifted. Only vacuum and drive systems still operate, just to dry the wet floor and move
the machine to the appointed charging area.
CAUTION!
Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.
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 (27) turns off the vacuum system when the recovery tank (19) 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 push-button (63),
then open the cover (20) and check that the float inside the grid (27) has gone down to the water level. Then
close the cover (20) and turn on the vacuum system by pressing the push-button (63).
When the recovery tank (19) is full, empty it according to the following procedure.
Recovery tank emptying
1. Stop the machine by releasing the pedal (4).
2. Lift the brush deck and the squeegee by pressing the One-Touch push-button (67).
3. Drive the machine to the appointed disposal area.
4. Empty the recovery water tank with the hose (24).
5. Remove the container with debris collection grid (26), empty it and clean it with clean water. Then install it on the suction hose
in the tank.
6. Then, rinse the tank with clean water.
