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.
