Maintenance
The grinder/polisher must be kept in a dry place, so the grinding and polishing wheels
are not made damp by steam or rain.
The grinding wheel often becomes uneven with use, so it is recommended that you
level it up at suitable intervals. When the grinding wheel is over 25% worn it is
advisable to replace it. An uneven grinding wheel leads to vibrations, which will
eventually ruin the bearings of the machine.
Damaged grinding units, eye guards and shields should be replaced to prevent
personal injury.
When the grinding wheel is to be replaced, remove the outer shield first. Unscrew the
nut so you can remove the outer flange and grinding wheel. The new grinding wheel
must not exceed the dimensions specified on the motor plate on the machine; it is
important that the hole dimensions are correct.
The grinding wheels are equipped with labels (plates made of a compressible
material), which are positioned around the hole on either side of the grinding wheel. If
these labels are missing or become damaged, they must be replaced by new labels
of the same size.
Fit the new grinding wheel and screw on and tighten the nut. Tighten the nut to the
extent that it can hold the grinding wheel firmly, but it must not be tightened so much
that the grinding wheel is put under considerable stress, as this can lead to unwanted
stresses in the grinding wheel.
