4.1.1 Changing the carbon brushes
The Automatic-Stop feature protects the machine from defects due to excessively consumed carbon brushes. The
machine is equipped with two carbon brushes, i.e. one is installed in each handle half.
The carbon brushes must be changed as follows:
• Unscrew four screws and remove the handle halves.
• Lift spring with screwdriver and remove brush.
• Install new brushes.
• Clean carbon brush holders, making absolutely sure not to change the arrangement of the elements of the carbon
brush assembly.
• Fit handle halves and fasten with four screws.
• Repeat this on the opposite side, making absolutely sure to avoid both handle halves from being opened at the same
time.
4.1.2 Replacing the Adapter Spacer
In order to ensure correct operation and extend the service life of the bevel heads, it is essential to ensure that the
surface of the adapter spacer is unblemished, i.e. without pits, deep scratches and\or broken edges. The adapter pin
should also be undamaged and retain its original length. The adapter spacer and/or adapter pin may get damaged
under certain conditions, however both can easily be replaced.
Replacing the spacer:
• Turn the fl ange head until it comes off .
• Unscrew the hex screw (C) on the side of the spacer (A).
• Screw the two M5 bolts (D) in the holes in the top of the spacer until they just touch the spindle shoulder (B).
Continue to screw the two M5 bolts alternately in small increments until the spacer is forced off the spindle.
• Now continue to screw the two bolts alternately in half turns deeper into the spacer. Remove the damaged spacer
when it comes off the spindle. Unscrew the two M5 bolts from the spacer and keep these for later use.
• Install the new spacer, ensuring that it rests securely on the spindle shoulder. Use a rubber mallet if necessary.
• Replace the adapter pin (E), ensuring the top is level with the top of the spindle.
• Retighten the hex screw on the side of the spacer.
