CHANGING SPEEDS AND ADJUSTING BELT TENSION
NOTE: A BELT POSITIONING SPEED CHART (E) FIG. 27, IS CONVENIENTLY LOCATED ON THE INSIDE TOP
COVER OF THE DRILL PRESS.
1. Disconnect the drill press from the power source.
2. Lift up the belt and pulley guard (A) Fig. 27.
3. Release belt tension by loosening tension lock knob (B) Fig. 27, and pivoting the motor (D) toward the front of the
drill press.
4. While holding the motor toward the front of the drill press head, position the belt (C) on the desired steps of the
motor and spindle pulleys, as shown in Fig. 27.
5. After the belt is positioned on the desired steps of the motor and spindle pulleys, pivot motor (D) Fig. 27, away from
the drill press head 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 belt (C) can be flexed about 1" out of line midway between the pulleys using light finger pressure.
