FRAME BLOCKING (U-JOINT]
The relation between the working head and the trolley is
the frame (U-joint), which allows rotation about two
perpendicular axes to better follow the profile of the floor.
The movement round one of axis can be blocked with
two screws to the plank, mounted on the front of the
frame(Fig.4.6). Unscrew the bolts and turn the plank so
it fixes the frame to the carrier with its tooth and then
tighten the bolts(Fig.4.6). Thus the lateral movement of
the machine is blocked.
THE CONTROL BOARD
1 Emergency button
used in Emergency situations for
stopping the motor
2 Digital RPM indicator
indicates the revolution per
minute of the grinding plates (not the revolution per minute of the
entire unit).
3 Potentiometer
changes the RPM of the grinding plates.
4 Inverter alarm led
Lights blue when the inverter goes into
alarm mode
5 Reset button
resets the alarm of the inverter
6 ON/OFF switch
starts/stops
the
motor
Power led (integrated in some models) lights green when the
power is on
7 Polishing/Grinding switch
In “grinding” position, the
operator has the possibility to control the rpm from 300 until
maximum 700 rpm. In “Polishing” position from 300-1100 rpm
maximum.
8
Water pump switch
Lights orange when the water pump is working.
STARTING THE MACHINE
First, follow the directions in chapter Safety Devices and Safety Instructions. Next, pull the emergency stop (Fig.4.8 1)
to ensure that the machine is in working condition. Check the potentiometer (Fig.4.8 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.4.8 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-S-E 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 (Fig.4.2-1) the
position for water feed and periodically start the pump (Fig 4.8-8) 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.4.8 6). Use the Emergency
button (Fig.4.8 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.4.8 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.4.8 5).
