press, position the belts (F) on the desired steps of the
motor and spindle pulleys, as shown in Figs. 27 & 28.
4. After the belts are positioned on the desired steps of
the motor and spindle pulleys, move motor (D) Fig. 28,
to the rear until the belt is properly tensioned and tighten
tension lock knob (B). The belt should be just tight
enough to prevent slipping. Excessive tension will
reduce the life of the belt, pulleys and bearings. Correct
tension is obtained when the belts (F) can be flexed
about 1" out of line midway between the pulleys.
