CHANGING SPEEDS AND ADJUSTING BELT TENSION
NOTE: A BELT POSITIONING SPEED CHART (E) FIG. 28, IS LOCATED ON THE INSIDE TOP COVER OF THE DRILL PRESS.
DISCONNECT MACHINE FROM POWER SOURCE.
1.Lift up the belt and pulley guard (A) Fig. 28.
2.Release belt tension by loosening tension lock knob
(B) Fig. 28, and the tension knob located on the other side of the head casting and moving tension lever (C) forward.pivoting the motor (D) toward the front of the drill press.
3.While holding the motor toward the front of the drill 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.
