Mounting the Grinding Tools
Before any work on the machine itself, pull
the mains plug.
Use only grinding tools with a permissi-
ble speed at least as high as the no-load
speed of the machine.
Grinding and cutting discs become very
hot while working; do not touch until
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 lock button 2.
Actuate the spindle lock button 2 only when
the grinder spindle is at a standstill!
Grinding/Cutting Disc
Pay attention to the dimensions of the grinding
disc. The mounting hole diameter must fit the
mounting flange 9 without play. Do not use re-
ducers or adapters.
When using a diamond cutting disc, take care
that the direction-of-rotation arrow on the dia-
mond cutting disc and the direction of rotation of
the machine (direction-of-rotation arrow on the
machine head) agree.
For mounting, see the illustration page.
Screw on the clamping nut 11 and tighten with
the two-pin spanner (see Section "Quick Clamp-
ing Nut").

fore switching on, check that the grind-
ing tool is correctly mounted and that it
can turn freely.
