INSTALL THE CHUCK (FIG. 11)
1. Inspect and clean the taper hole in the chuck and the
spindle. Remove all grease, coatings, and particles from the
chuck and chuck arbor surfaces with a clean cloth.
2. Open the chuck jaws by manually turning the chuck barrel
clockwise. Make sure the jaws are completely recessed
inside the chuck.
3. Seat the chuck on the chuck arbor by placing a block of
wood (not included) under the chuck and tapping the wood
with a hammer (not included). Alternatively, tap the chuck
with a rubber mallet (not included). Pull firmly down on the
chuck to ensure it is properly seated on the spindle. If it
comes loose, clean the tapers and repeat steps 1-3 until the
chuck is properly seated.
CAUTION: To avoid damaging the chuck, make sure the jaws
are completely recessed into the chuck. Do not use a metal
hammer to drive the chuck into the spindle.
REMOVE THE CHUCK
1. Turn the feed handles to lower the chuck to the lowest
position.
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. Alternately, you may use a set of #6 Jacobs wedges (sold serperately).
NOTE: Be prepared to catch chuck as it falls, or place a cloth on the table to avoid damage to the table or
chuck.
RAISE AND LOWER THE TABLE (FIG. 12)
1. Loosen the support lock handle (Fig. 12 - 1) and turn the crank handle (Fig. 12 - 2) until the table is at the
desired height.
2. Tighten the support lock handle before drilling.
ROTATE THE TABLE (FIG. 12)
1. Loosen the support lock handle (Fig. 12 - 1) and turn the table around the column to the desired position.
NOTE: The rack should rotate around the column with the table support bracket. If the rack binds and does
not rotate, slightly loosen the set screw in the rack collar.
