ble speed at least as high as the no-load

very hot while working; do not touch un-
til they have cooled.
Clean the grinder spindle and all parts to be
mounted. For clamping and loosening the
grinding tools, lock the grinder spindle 5 with
the spindle locking button 2.
Actuate the spindle locking button 2 only
when the grinder spindle is at a standstill!

disc. The mounting hole diameter must fit the
mounting flange 9 without play. Do not use re-
ducer pieces or adapters.
When using a diamond cutting disk, take care
that the direction of rotation arrow on the dia-
mond cutting disk and the direction of rotation of
the machine (direction of rotation arrow on the
machine head) agree.
