STARTING THE MACHINE
First, follow the directions in the chapter on Safety Devices and Safety Instructions. Next, release the emergency stop (12), turn the
Ready switch (Fig. 4.6 9) to the ON position to put the machine in standby mode. Check the potentiometer (8), and ensure that it is set to
the working speed. If working wet, add water to the floor surface. If working dry instead switch on the vacuum unit. Finally, hold the
machine firmly and push the RUN button (11).
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. 4.2‐1) and periodically run the pump (fig. 4.10‐11) 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 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 the motor comes to
rest, as the tools could damage the surface. To stop the machine:
1.Push the STOP button (10) .
2.Turn the OFF/ON (9) switch in position OFF, this will cut the voltage to the invertor and the green light will turn off
While working do not turn off directly from the switch READY OFF / ON or from the Emergency Stop, but follow the above
mentioned steps 1 and 2.
Use the Emergency button (12) only in emergency.
Remember not to hold the machine in one spot before turning off the motor.
ALARM
The Reset button (4) will light when the inverter goes into alarm mode. The most common failure is motor overload. To exit alarm mode,
push the reset button (4). A code on the inverter's display indicates the type of the alarm. When the same alarm is repeated several times,
it is imperative to find and eliminate the cause of it, less the inverter become damaged.
