Faults and trouble shooting

The machine will not run
• Check the power supply and the power cables and make
sure that they are not damaged.
• Check that the emergency stop button is not pressed by
turning it clockwise.
Machine is hard to hold onto
• Not enough diamonds under the machine (if grinding thick
glue or soft floors, too few diamonds under the machine
will greatly increase the load on grinder and operator).
Usually also accompanied by high current draw by motor.
Increase number of diamonds under machine to reduce
load on grinder and operator.

• Rubber shock absorber pads in grinding unit may be worn
out or damaged. Check and change if necessary.
• Diamonds may not be fitted correctly or have different
heights. Check to ensure all diamonds are fitted correctly
and are the same height.

• The machine is overloaded and the overload protection
has been released. Reduce load. The machine will reboot
after about a minute when the motor has cooled off.
The machine stops during start-up
• The electric motor has been overloaded or a phase is
missing. Allow the machine one or two minues to reset
and try again. When this does not help, contact an
authorised service workshop.
