USING THE ON-BOARD BATTERY CHARGER

WARNING: batteries give off hydrogen gas. Keep the battery well away from sparks and open flames when recharging.

When the battery on the machine is discharged, the red Led lights up on the control panel and all machine functions will automatically stop working: the operator must now switch off the machine and recharge the battery by plugging the battery charger cable into an a.c. mains power socket ( the yellow Led remains alight on the control panel as long as the battery is recharging). Once the battery is fully charged, the green Led lights up on the control panel, at which point the charger can be unplugged from the power socket and the machine is ready for operation.

IMPORTANT NOTE: USING THE MACHINE BEFORE THE BATTERY IS FULLY CHARGED (GREEN LED ALIGHT) WILL REDUCE THE LIFE AND CHARGING CAPACITY OF THE BATTERY AND INVALIDATE THE WARRANTY.

The charger on this machine is designed and built specifically for use with GEL batteries.

NOTE: plugging the battery charger into the mains power supply while the sweeper is in operation, all machine functions will shut off automatically. Never connect the battery charger when the machine is in use.

STARTING THE MACHINE

WARNING: the machine must be used only by authorized personnel.
DO NOT leave the machine unattended when switched on;
DO NOT use the machine to sweep up liquids; ALWAYS switch the machine off before leaving it unattended.

To start the machine, proceed as follows:

• Press the ON/OFF button to power up the electrical system.
• Check that the green Led (battery charge level indicator) is alight.

Select the appropriate work program:

• Press work program button 1 for smooth surfaces and light soiling.
• Press work program button 2 for concrete and asphalt surfaces, carpet and heavy soiling.

NOTE: using work program 2, the battery will discharge at a faster rate and need recharging sooner.

ENERGY SAVING FUNCTION: after 10-15 seconds of inactivity (no function in use) the machine switches off automatically. Press the ON/OFF button again to resume operation.

INSTRUCTIONS FOR CORRECT OPERATION

Having followed all the steps required for initial preparation and start-up of the machine, it is now ready to sweep floors. To ensure the sweeper always gives maximum performance, take care to follow the directions in this manual, which are designed to maximize the levels of efficiency delivered by the machine, while minimizing the risk of damage.

Important:

• Do not use the machine to pick up wires, string, straps etc., or to sweep up water or other liquids.
• For large localized volumes of material (waste paper, leaves, etc.), elevate the front of the machine by pulling back and down on the handle for as long as necessary to pick up the debris. On finishing work, operate the filter shaker.

WARNING: the sweeper must not be used on wet surfaces. Should the area being cleaned happen to be slightly damp (with residual moisture on the floor), the suction motor must be switched off in order to avoid the risk of damaging the filter. Damage to the machine caused as a result of picking up wet debris is not covered by the warranty.

WARNING: if the sweeper is not used for a period of longer than one month, detach the RED and BLACK battery connectors.
If the sweeper remains idle for more than a week, leave it connected to the a.c. mains.
