Mark V 520 Summary Manual
SM - 11
10. To install the drill chuck, mount the chuck on
the spindle and align the chuck's set screw
with the spindle knob's set screw, as shown in
Figure B-52. This allows the chuck's set screw
to set on the flat part of the spindle. Use a 5/
32" Allen wrench to securely tighten the drill
chuck's set screw.
13. Set the combination square against the bit and
table, as shown in Figure B-55. The square
should contact the bit along its entire length.
When the table is exactly perpendicular to the
drill bit, lock the table, as seen in Figure B-56.

11. Install a 3/8" to 1/2" straight drill bit in the
drill chuck and use the chuck key to lock it
place. See Figure B-53.
NOTE
Check the straightness of the drill bit by rolling it on
a flat surface. You can also hand-rotate the drill
chuck while holding the combination square against
the drill bit and the table. If the bit is not straight
DO NOT use it for these alignment instructions.
12. With the drill bit above the table opening, use
the quill feed to extend the bit 1/2" into the
table opening, as in Figure B-54.

14. Both 90° stops (shown in Figs. B-57 and B-58)
should contact the underside of the table. If
they don't, use a 1/2" wrench to adjust the
stops.
15. Recheck the setting by loosening the tilt lock,
moving the table, and then repeating Steps 13
and 14. (Rechecking the settings is very im-
portant!)
