4.6 STARTING THE MACHINE
First, follow the directions in the chapter on Safety Devices and Safety Instructions. Next, release the
emergency stop (4),
turn the
Ready switch (10)
to the ON position to put the machine in standby mode. Check the
potentiometer (12)
, and ensure that it is set
to the working speed. If you are working wet, add water to the floor surface by starting the
pump (7)
. If you are working dry make
sure your machine is connected to the vacuum unit. Finally, hold the machine firmly and push the
RUN button (13)
.
4.7 OPERATING THE MACHINE
Guide the machine in straight lines across the floor, slightly overlapping the previously completed surface with each
new line. 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 machine while tools are still running as they will mark the surface of the floor. When
working wet, select the destination of the water feed with the water tap (fig. 4.2) and periodically run the pump to
release water onto the floor surface. Starting the pump is possible only if the machine motor is on. When working dry,
check the floor surface periodically for dust accumulation. Check regularly to see if you’re vacuum works properly.
4.8 STOPPING THE MACHINE
The stopping of the machine must be done gradually until the motor stops. Do not stop moving the machine before the motor
comes to rest, as the tools could damage the surface.
To stop the machine:
1.Push the STOP button (3) .
2.Turn the
ON/OFF
(10) switch
in position
OFF, this will cut the voltage to the invertor and the green light will turn off.
