CAUTION
Bearing overload hazard.
Setting the preload on the intermediate
shaft too tight will cause bearing overload.
Setting the preload too loose will allow
shaft to not be parallel.
Use caution when adjusting. Start with the
preload too loose, and gradually increase
the preload until the correct resistance
to rotation is achieved. Increase the
preload by turning the adjusting screw by
a maximum of 1/6 rotation (60 degrees),
and striking the housing with a hammer
to make sure the bearing is sliding.
Check resistance to rotation after each
adjustment.
