INSTALLING THE CHUCK
1. Unplug your drill press before you begin installing the chuck. Lower the drill press table and place
a cloth on it to protect the chuck if it is dropped.
2. Wipe the chuck and spindle with a clean rag. Do not use solvents yet, these will be used when you
are ready to set it into place.
3. Completely remove any burrs found on the inner mating surface of the chuck with a diamond
coated tool or a fine file. Use a grade 000 steel wool pad to lightly go over the chuck and spindle.
This removes oxidation and dirt that you cannot see.
NOTE:
Do steps 1-3 even if your chuck is new. New
chucks can still have burrs, oxidation, and dirt.
WARNING:
Before any assembly of the chuck to the drill
press spindle, clean all mating surfaces with a non-petro-
leum based product, such as acetone or lacquer thinner.
Any oil or grease used in the packing of these parts must
be removed; otherwise the chuck may come loose during
operation.
4. Use lacquer thinner or acetone on a lint free rag to clean the chuck. Do not touch these surfaces
with your hands after cleaning. Rubbing alcohol does not work well, as it contains oil. Let the chuck
dry before continuing.
5. Retract the jaws of the chuck all the way into the body. Slide the chuck’s socket onto the spindle.
See Fig. 7.
CAUTION:
To avoid damaging the chuck, make sure the jaws are completely recessed into its
body and only tap the chuck one time, with a firm tap. Do not use excessive force. Do not use a metal
hammer to drive the chuck into the spindle.
6. Using hand force, firmly push the chuck up onto the spindle. Using a rubber mallet or dead blow
hammer, tap the chuck upwards once to lock the tapers together. You can also use a piece of wood
between the chuck and a standard hammer. Test the fit by gently pulling downward on the chuck. If
the chuck pulls off, go back to step one and try again, making sure to thoroughly clean the mating
sur- faces. Your chuck is now set into your drill press and should stay in place until you need to
remove it.
REMOVING THE CHUCK
1.Turn the feed handles to lower the chuck to the lowest position, making it close to the table.
2.Place a ball joint separator above the chuck and tap it lightly with a hammer to cause the chuck to
drop from the spindle. You should hold the chuck and be ready to catch it when it is released.
Alternate Method:
Place the chuck key into the opening on the side of the chuck. Open the drill press cover and hold the
spindle pulley stationary. Using the chuck key for leverage, rotate the entire chuck clockwise while
gently pulling downwards. Remove the chuck from the spindle.
