MOUNTING THE GRINDING WHEEL
Insert the wheel shank into the collet. By means
of open end spanner S17 hold spindle 2 and
tighten nut 1 by spanner S17. Use only undam-
aged spanners, otherwise there exists a danger
of injuring the nut. Make sure the wheel shank
diameter corresponds to the collet aperture.
Tighten the grinding tools as deep as possible
into the collet. Dimension l0 should not exceed
a value dependent on grinding tool dimensions
(refer to fig.1 and table 1).

his agent in order to avoid a safety hazard.

ing.
