16.2.5 Replacing the Grinding Wheel

Do not install a brush in the grinding wheel housing or vice versa.
Always replace a disc with a model of the same mass and size.
Replace the grinding wheel as soon as its diameter is 140 mm or less. Do not mount
or use discs with a diameter less than 140 mm. Do not use damaged discs.
Only use "glazed" grinding wheels with an indicated speed equal to or greater than
that indicated on the type plate of the tool (see imprint on the grinding wheel).
Integrity check of a new disk:
Before mounting a new disc, sound test it to check its general condition. To perform this test, the
disc must be dry and clean, otherwise the radiated sound may be attenuated.
To verify identity, lightly tap the side of the disc with a non-metallic object (wooden handle of a
screwdriver, rubber hammer).
An undamaged grinding wheel produces a clear sound, a damaged one a dull or rattling sound.
Disc Exchange procedure:
8. Replace the used grinding wheel (5) with a new one. (Make sure that the flanges and the

than ten millimetres.
