– Fit the ribbed V-belt on the belt
pulley of the bearing, mount the
guard and loosely turn in the
fastening screws.
:
Turn the hexagon on the
tensioner clockwise.
:
The tensioner is engaged by the
force of the spring after roughly 1/
8 of a turn. The hexagon is now
turned on by the spring tension
until the belt is tight.

Note:
The hexagon must not be forced, as
the belt tension is obtained through
the spring tension.
– Tighten down all three fastening
screws, starting with the one at
the back.
– Tightening torques,
Since the radial truth of running of
the abrasive wheel changes if the
shaft diameter changes (due to
scoring, etc.), it is sufficient to
carefully inspect the shaft around
the mount for the abrasive wheel.
The axial truth of running, on the
other hand, depends on the
condition of several parts and
should therefore be determined by
measurement.
– Undo the screw and remove the
thrust washer,

:
Secure a dial gauge holder (1)
with fitted dial gauge (2) on the
guard so that the axial truth of
running can be determined for a
