WARNING! To avoid injury or accident by
the chuck key ejecting forcibly from the
chuck when the power is turned “ON,” use
only the self-ejecting chuck key supplied
with this drill press. ALWAYS recheck and
remove the chuck key before turning the
power “ON.”
3. Make sure that the drill is centered in the
chuck.
4. Turn the chuck key clockwise to tighten
the jaws.
NOTE: To prevent the workpiece or backup
material from being torn from your hands
while drilling, you MUST position the
workpiece against the LEFT side of the
column. If the workpiece or the backup
material is not long enough to reach the
column, clamp them to the table. Failure
to secure the workpiece could result in
personal injury.
DRILLING TO A SPECIFIC DEPTH
(FIG. 22)
Drilling a blind hole (not all the way through
workpiece) to a given depth can be done
two ways:
Workpiece method
1. Mark the depth of the hole (1) on the
side of the workpiece.
2. Turn the switch to “OFF,” bring the drill
bit down until the tip is even with the
mark.
3. Hold the feed handle (2) at this position.
4. Depress the spring-loaded button (3)
and move the stop nut (4) until the
bottom of the nut contacts the stop (5).
5. Connect the machine to the power
source and drill a test hole to check the
adjustment. The drill bit will now stop
after traveling the distance marked on
the workpiece.
NOTE: Readjust, if necessary, by
rotating the stop nut (4) for ne
adjustment. You do not have to depress
the button (3) to rotate the stop nut (4).
Depth scale method
NOTE: With the chuck quill assembly fully
retracted the tip of the drill bit, the drill bit
must be just slightly above the top of the
workpiece.
1. Turn the switch to “OFF,” rotate the feed
handle (2) until stop (5) points to the
desired depth on the depth scale (6) and
hold the feed handle (2) in that position.
2. Depress the spring-loaded button (3)
and move the stop nut (4) until the
bottom of the nut contacts the stop (5).
3. Connect the machine to the power
source and drill a test hole to check the
adjustment. The drill bit will stop after
traveling the distance selected on THE
DEPTH SCALE.
NOTE: Readjust, if necessary, by
rotating the stop nut (4) for ne
adjustment. You do not have to depress
the button (3) to rotate the stop nut (4).
LOCKING THE CHUCK AT THE DESIRED
DEPTH (FIG. 23)
1. Turn the switch to “OFF,” turn the feed
handles until the chuck (1) is at the
desired depth. Hold the feed handles at
this position.
2. Turn the stop nut (2), located under the
stop (3), counterclockwise and upwards,
until it is against the stop (3).
3. The chuck will now be held at this
position when the feed handles are
released.
REMOVING CHUCK AND ARBOR
(FIG. 24)
1. With the switch “OFF” and the unit
unplugged, adjust the depth stop nut (1)
to hold the drill at a depth of 3 in. (7.6
cm). (See instructions for “LOCKING
CHUCK AT DESIRED DEPTH”).
2. Align the key holes in the spindle (2) and
quill (3) by rotating the chuck by hand.
3. Insert the key wedge (4) into the key
holes (2 & 3).
