Check the grinding wheel or brush before replacement, do not use brushes and wheels with dents,
cracks, excessively worn or otherwise damaged.
Disconnect the power tool from power supply.
Ensure that new grinding wheel or brush is characterized by maximal rotational speed equal to 2850 rpm or
more. Notice that the nut of the left grinding wheel is left-hand threaded and it must be turned clockwise
to unscrew. Nut of the right grinding wheel is right-hand threaded and it must be turned counter-clockwise
to unscrew.

Hold the wheel or brush firmly (wear protective gloves to protect your hands).
Unscrew the nut that fixes the grinding wheel and the outer flange (fig. H and I).
Remove worn out or damaged brushing or grinding wheel (fig. K).
Install new grinding wheel or brush onto the shaft and ensure that there is a washer between the wheel
and flange on each side, and that the wheel or brush is slide fitted, not clearance fitted.
Screw the nut that fixes the wheel back on its place.
Hold brushing or grinding wheels when tightening the nuts.
Be careful not to damage the shaft thread due to applying excessive torque.
Install wheel cover (4) and fix it with three screws.
