Spindle speeds (Fig. 10)
This drill press offers 5 spindle speeds from 620 to 3100 RPM. The highest speed is obtained when the
belt is positioned on the largest motor pulley step and the smallest spindle pulley stop.
WARNING: Disconnect the drill press from the power source before making any speed adjustments.
Adjust speeds and tension the belt (Fig. 11)
1. Open the drill press pulley cover (1).
2. Loosen the belt tension knob (2).
3. Pull the motor (3) toward the drill press head.
4. Set the belt on the desired steps of the motor and spindle
pulleys according to the belt positions on the spindle
speed chart (Fig. 10).
5. Pull the motor away from the drill press head to increase
the belt tension. Tighten the tension knobs (2).
6. The belt (4) should be tight enough to prevent slippage.
Correct tension is set if the belt flexes about 1/2" (13 mm)
when thumb pressure is applied at the midpoint of the belt between the pulleys.
