ASSEMBLY
INSTALLING & REMOVING THE CHUCK
It is important that the tapered
hole in the chuck, tapered hole in the spindle and
both tapered ends of the arbor are free of any
grease, oil, lacquer or rust protection.
These tapered surfaces must be absolutely clean
for a precision fitting of the parts, so slipping of
the chuck during use does not occur unless there
is extreme rotational pressure during use. This is
a safety feature of this type of friction fit joint.
IMPORTANT!
NEVER HIT THE CHUCK WITH
A METAL HAMMER. This could damage the chuck
assembly, arbor or drill press spindle.

INSTALLING THE CHUCK
1. Carefully insert the arbor’s short, JT3 tapered end
into the rear tapered hole of the chuck. FIG. 9.
2. Next, take the chuck and insert the long, MT2
tapered end of the arbor into the drill press spindle’s
tapered hole. Make sure to align the flat part of the
arbor with the slot in the spindle. FIG. 10.
3. Open the jaws of the chuck until the 3 jaws are
completely hidden inside of the chuck body.
4. Using a rubber mallet, or hammer with a block
of wood protecting the chuck, tap the chuck with its
arbor into the drill press spindle.
This will securely
seat the chuck in place for drilling. FIG. 11.

REMOVING THE CHUCK
1. Open the chuck jaws as wide as possible to
prevent damage in the following steps.
2. Lower the spindle until the slot in the spindle is ex-
posed, and lock it in place with the lower, Depth Stop
Block/circular nut (#14, on Parts Diagram D). FIG. 12.
3. Turn the chuck until the slots in the spindle (#3D)
and Quill (#6D) align, and a through-hole is exposed.
4. Insert the Key-Drift (#5D), into the slots and hole
above the chuck arbor, with the drift’s flat side up.
5. Gently tap the key-drift with a mallet to release the
chuck.
NOTE:
Be prepared to catch the chuck as it is
released to prevent any damage to it or the arbor.
