Note: Do not overtighten the drawbar. Overtightening makes arbor removal difficult and will damage the arbor and threads.

Model G0704 (Mfg. Since 08/11)

NOTICE

The Model G0704 drawbar will extract the arbor from the spindle. Once the arbor or collet has broken free from the spindle taper, be sure to properly support it while continuing to loosen the drawbar. Failure to properly support the arbor or collet while loosening the drawbar will result in the arbor or collet falling out of the spindle, causing damage to machine components.

To remove the chuck and arbor from the spindle:

1.DISCONNECT MILL/DRILL FROM POWER!

2.Remove the drawbar cap.

3.Lock the quill in place with the quill lock lever.

4.Use the included spindle pin to prevent the spindle from turning while you use an 8mm wrench to loosen the drawbar 2–3 turns. DO NOT continue loosening the drawbar without supporting the drill chuck or it will fall from the spindle.

5.Hold the chuck with one hand and finish loos- ening the drawbar until the chuck falls out of the spindle.

Note: The chuck is attached to the arbor using a B-16 taper. This attachment is con- sidered to be semi-permanent. There should be no need to remove the chuck from the arbor.
