2.2.3 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.
Belt arm

2.3.1
Fitting the belt arm
If the grinder is fitted with a grinding
screen this must be completely removed
before the belt arm is fitted.
When fitting the belt arm, first fit the link
(H). The belt arm can then be fitted onto
the link and you can secure it with the bolt
(I). Then you can put the spacer (G) on the
shaft, followed by the contact wheel (F)
and finally the nut (E). Then put the
grinding belt (D) onto the belt arm, and
finally secure the outer shield (C) to the
wheel (B) and nut (A).
