THE CONTROL BOARD
1. Emergency button used in Emergency situations for stopping the motor
2. Inverter alarm led lights up if inverter is in alarm mode (see Paragraph
Alarm)
3. Power loss led Lights by power connection loss (see Paragraph Power
loss)
4. Forward/Reverse switch choose forward for clockwise rotation of the grinding plates
or reverse for anti- clockwise rotation of the grinding plates
5. ON/ OFF switch-Power led starts/stops the motor, lights green when the power is on
6. Potentiometer changes the RPM of the grinding plates,from 300-1100
rpm
STARTING THE MACHINE
First, follow the directions in chapter Safety Devices and Safety Instructions. Next, pull the
emergency stop (1) to ensure that the machine is in working condition. Check the
potentiometer (6) 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 turn the start switch (5).
Figure 4.5
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 16-S machine in one spot while the tools are still working
because they will leave marks on the floor surface. When working wet, open the water tank periodically to release
water onto the floor surface. When working dry, check the floor surface periodically to ensure that dust is not
accumulating on the surface, also check regularly if 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 (5). Use the
Emergency button (1) 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 led (2) will light incase and stays lighted the inverter is in alarm mode. The most common failure is
motor in overload. To reset the alarm mode, disconnect the machine from the power supply.
POWER LOSS LED
When the machine stops working and the power loss led (3) flashes means that the power connection is
disconnected.
