STARTING THE MACHINE
First, follow the directions in chapter Safety Devices and Safety Instructions. Next, pull the emergency stop (12) to ensure that the
machine is in working condition. Check the potentiometer (8) and ensure that it is set at the working speed. If working wet, add
water to the floor surface. If working dry, omit this step, and instead, switch on the vacuum unit. Finally, hold the machine firmly
and push the start button (11).
OPERATING THE MACHINE
Guide the machine in straight lines across the floor, and with each new line overlap a little bit of the previously completed surface.
Work at a constant speed allowing the tools time to work at a speed appropriate for the tools’ grit size. Avoid vibrations. Do not stop
the Lavina® S machine in one spot while the tools are still working because they will leave marks on the floor surface. When working
wet, preliminary chose with the water tap(Fig4.2) the position for water feed and periodically start the pump to release water onto
the floor surface(Fig.4.6 Pos.5). When working dry, check the floor surface periodically to ensure that dust is not accumulating on
the surface, also check regularly that your vacuum works properly.
STOPPING THE MACHINE
The stopping of the machine must be done gradually until the motor stops. Do not stop moving the machine before arresting the
Motor, as the tools could damage the surface. To stop, push the off button (10). Use the Emergency button (13) only in emergency
or use it to switch the power totally off. Remember not to hold the machine in one spot before turning off the motor.
ALARM
The Alarm light (4) will light incase inverter goes in alarm mode. The most common failure is motor in overload. To reset the mode
push reset button (9).
