Disconnect the drill press from the power
source before replacing the belt.
Belt tension and drill press speed is controlled by automatic

function of this drill press.
1. Plug in the drill press and turn it ON. Adjust the speed to
the highest setting, then turn the drill press OFF and
unplug it.
2. Open the belt cover (remove the Phillips-head screw from
the right side, then open the lid.

4. Place the new belt on the motor pulley, then press down
on the bottom side of the pulley as before and get the belt
as close to the motor shaft as possible. Make sure
the bottom side of the pulley is pushed fully downward.
