2.1.2 - Mounting

Mount the unit directly on the driven shaft of the machine,
then secure it axially by tightening two pointed grub screws
provided, (Pbh series) or by one screw and washer at the end
of the shaft.
In order to make easier the mounting and later a possible
removal, it is strongly recommended to coat the driven shaft
and the hollow shaft with molybdenum disulfur grease.
Only parallel keys.
