STARTING THE MACHINE
First, follow the directions in chapter Safety Devices and Safety Instructions. Next, pull the emergency stop (Fig.4.5 1)
to ensure that the machine is in working condition. Check the potentiometer (Fig.4.5 2) 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 button (Fig.4.5 6).
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 32® Pro/32®HV Pro 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 switch the off switch (Fig.4.5 6). Use the Emergency
button (Fig.4.5 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 light ((Fig.4.5 4) will light incase inverter goes in alarm mode. The most common failure is motor in overload.
To reset the mode push reset button ((Fig.4.5 5).
