To assemble the drill chuck and mount it to the spindle:
1.Use mineral spirits to thoroughly clean the drill chuck and arbor, and dry all surfaces before assembly. Follow all safety warnings on the container of mineral spirits. Failure to clean the mating surfaces may cause the tapered fit to loosen during operation, resulting in separation, which could lead to serious injury.
2.
3.Place the drill chuck face down on a workbench. The arbor has a short taper and a long taper. Place the short taper into the socket in the back of the drill chuck and tap it with a rubber or wooden mallet, as shown in Figure 15. If the chuck fails to remain secure on the arbor, repeat Steps 1 & 2.

4.Slide the arbor into the spindle while slowly rotating the drill chuck. The flattened end of the arbor (the tang, shown in Figure 15) will engage with a rectangular slot inside the spindle.
5.Once the arbor has seated into the spindle completely, tap the chuck with a rubber mallet, as shown in Figure 16.
DO NOT use a steel hammer on the drill chuck to seat the arbor into the spindle. You will damage the chuck or spindle, which may make them unusable or unsafe.
