TO TURN THE DRILL PRESS OFF: With the switch
key inserted into the switch, push the switch
down to turn OFF ( O ).
TO LOCK THE DRILL PRESS: Place the switch in
the OFF ( O ) position. Remove the switch key
from the switch and store in a secure location.
IMPORTANT: ALWAYS remove the switch key
when the tool is not in use and keep it in a safe
place. In the event of a power failure, turn the
switch OFF ( O ) and remove the key. This action
will prevent the tool from accidentally starting
when power returns.
Always make sure the workpiece is not in con-
tact with the bit before operating the switch to
start the tool. Failure to heed this warning may
cause the workpiece to be kicked back toward
the operator and result in serious personal in-
jury.
SELF-EJECTING CHUCK KEY
The self-ejecting chuck
key ensures the chuck
key is removed from
the chuck before the
drill press is turned on.
In order to loosen or
tighten the chuck using
the chuck key, push the
key into the key hole located on the chuck. Ro-
tate the key clockwise to tighten the chuck or
counter clockwise to loosen the chuck.
WARNING: use only the self-ejecting chuck
key provided. Always remove chuck key. Failure
to heed this warning could result in serious per-
sonal injury.
TABLE ROTATION
The table can be rotat-
ed out of the way when
drilling large objects.
1. Loosen the table lock
handle.
2. Rotate the table to
the desired position.
3. Retighten the table
lock handle.
INSTALLING AND REMOVING BITS
1. Unplug the drill press.
2. Open or close the chuck jaws to a point where
the opening is slightly larger than the bit size
you intend to use.
3. Insert drill bit into the chuck the full length
of the jaws.
4. Tighten chuck jaws securely using chuck key

provided. Do not use a wrench to tighten or
loosen chuck jaws.
5. Remove chuck key.
6. To remove the drill
bit, reverse the steps
listed above.
Do not insert drill bit
into chuck jaws and
tighten as shown in
figure 13.
This could cause drill bit to be thrown from the
drill press, resulting in possible serious personal
injury or damage to the chuck.
OPERATION
1. Using a clamping de-
vice, secure the work-
piece to the worktable.
To protect the top sur-
face of the workpiece,
use a piece of scrap
wood between the vise
and the workpiece.
2. Select the proper drill bit based on the hole
size desired. For large holes, drill a pilot hole
first, using a smaller diameter bit.
3. Select and set the recommended spindle
speed. Refer to "Changing Speeds" in the Ad-
justments section of this manual.
4. Set table assembly to desired height. Refer
to "Adjusting Table" Height in the Adjustments
section.
5. If desired, set feed shaft at desired spindle
depth. Refer to "Adjusting Depth Gauge" in the
Adjustments section.
6. Make sure the work table is free of all loose
objects and the bit is not in contact with the
workpiece.
7. Plug electrical cord into power supply and
turn switch ON. Make sure spindle rotates freely.
8. Slowly lower drill bit into workpiece. Do not
force the bit; let the drill press do the work.
9. Once the hole is completed, allow the spindle
to return to its normal position. This will auto-
matically raise the chuck and bit.
DRILLING TIPS
1. If a large hole is needed, it's a good idea to
drill a smaller pilot hole before drilling the final
one. Your hole will be more accurately posi-
tioned, rounder, and the bits will last longer.
2. If the hole is deeper than it is wide, back off
occasionally to clear the chips.
3. When drilling metal, lubricate the bit with oil
to improve drilling action and increase bit life.
4. As you increase the drill size, you may need to
reduce the spindle speed.
