ELECTRICAL INFORMATION
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance
for an electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has an
equipment grounding conductor and a grounding plug. The plug MUST be plugged into a matching outlet that is
properly installed and grounded in accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by a
licensed electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The conduc-
tor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or
replacement of the electric cord or plug is necessary, DO NOT connect the equipment grounding conductor to a
live terminal.
CHECK with a licensed electrician or service personnel if you do not completely understand the grounding instruc-
tions or whether the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have three-pronged plugs and outlets that accept the
tool’s plug as shown in Fig. A. Repair or replace a damaged or worn cord immediately.
CAUTION: In all cases, make certain the outlet in question is properly ground-
ed. If you are not sure, have a licensed electrician check the outlet.
WARNING: This tool is for indoor use only. Do not expose to rain or use in
damp locations.
FIGURE A

GUIDELINES FOR USING EXTENSION CORDS
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting
in loss of power and overheating. The table below shows the correct size to be used according to cord length and
nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord
or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected
with a 15 A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF
position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a
lower voltage will damage the motor.

ASSEMBLY
1. Position the base on the floor. Attach the column to the base
using four M10X30 hex head bolts (Fig. 1).
2. Loosen the set screw and remove the column collar and gear
rack from the column. With the help of a friend, place the rack
inside the table bracket before sliding the table assembly with
the rack down onto the column (Fig. 2). Place the column collar
down over the rack after positioning the rack and the table in
place. Tighten the collar’s set screw with a hex wrench to hold
the rack into position.
3. Install the table adjustment crank (Fig. 3 - 1). Secure it in
place by tightening the set screw (Fig. 3 - 2). This handle will
control the height of the drill press table.
4. Screw the table locking handle into position (Fig. 4 - 1). Tight-
ening this handle prevents the table from swivelling and having
its height adjusted.
5. Install the head assembly with the help of a friend by care-
fully lifting the head above the column. Slide it onto the column,
making sure the neck goes down as far as possible (Fig. 5).
6. Align the head with the base so they are parallel with one an-
other and facing the same direction. Tighten the set screw (Fig.
6 - 1).
7. Install the feed handles (Fig. 7 - 1) into place using three
M8X12mm socket head screws (Fig. 7 - 2).

1. Turn the feed handles to lower the chuck to the lowest position.
2. Slide the wedge into the opening in the quill. Tap on the wedge using a hammer (not included). The chuck and
arbor will drop out.
Note: To avoid possible damage to the drill or chuck, be prepared to catch the chuck as it falls. As a safeguard,
the table can be raised to its maximum height as a backup in case you miss the falling chuck.
MOUNT THE DRILL PRESS (Fig. 14)
The drill press must be securely fastened through the mounting holes to a stand or workbench with heavy-duty
fasteners. This will prevent the drill press from tipping over, sliding, or walking during operation.
IMPORTANT: If the stand or workbench has a tendency to move during operation, fasten the workbench se-
curely to the floor.
ADJUSTMENTS
To adjust the height of the drill press table, loosen the table locking handle (Fig. 15 - 2) and turn the table adjust-
ment crank (Fig. 15 - 1).
To bevel the table in either direction, loosen the hex bolt located underneath the table (Fig. 16 - 1). Bevel the
table in either direction (Fig. 17). Once the desired position has been achieved, retighten the hex bolt (Fig. 16 - 1).
To swing the table around the column, loosen the locking handle (Fig. 15 - 2) and swing the table and the rack
into the desired position (Fig. 18). Retighten the table locking handle once the desired position has been reached.

scale ring in place with the depth knob (Fig. 19 - 2). The spindle will
now stop after traveling the selected distance.
SPEED ADJUSTMENT (FIG. 20 & 21)
This drill press has 12 speeds. The speeds can be changed by chang-
ing the belt locations on the motor pulleys as shown in Fig. 21.
To change the locations on the pulleys, open the belt cover. Loosen
the wing screw and the two nuts on the motor support plate (Fig. 20 -
3). Turn the belt tension adjustment handle (Fig. 20 - 2) to loosen the
belt tension. Then change the belt’s location to the desired speed.
QUILL SPEED ADJUSTMENT
The quill return spring may need adjustment if the quill starts re-
turning too slowly or rapidly. Make sure to wear gloves during quill
spindle adjustments to help prevent injuries from sudden and rapid
disengagement of the spring housing.
1. Loosen the screw and nut (Fig. 22 - 1 and 2), making sure that the
spring housing (Fig. 22 - 3) remains engaged with the head casting.
2. While firmly holding the spring housing, pull out the housing and
rotate it (counterclockwise to increase or clockwise to decrease the
spring tension) until the set screw (Fig. 22 - 4) becomes engaged with
the next notch on the spring housing. Turn the nut (Fig. 22 - 2) until
it contacts the spring housing. Tighten the screw (Fig. 22 - 1) against
the nut to hold the housing in place.

must be clamped or bolted to the table to avoid injury.
GENERAL DRILLING GUIDELINES - DRILLING A HOLE
WARNING: To prevent the workpiece and the backup material from slipping from your hand while drilling, po-
sition the workpiece and backup material to the left side of the column. If the workpiece and the backup material
are not long enough to reach the column, clamp the workpiece and backup material to the table. Failure to do this
could result in personal injury.
1. Mark where you want to drill the workpiece by using a center punch or a sharp nail. Turn ON the laser to mark
your drilling point also.
2. Before turning the drill press ON, turn the feed handles to bring the drill bit down. Line the drill bit tip up with
the mark. Clamp the workpiece in place.
3. Turn ON the drill press and pull down on the feed handles with the appropriate force needed to allow the drill
bit to drill the material.
4. It is good practice to touch the bit to the surface before fully committing to the cut to mark the surface of your
work piece. This helps ensure a straighter cut/hole while maximizing accuracy.
5. Make sure to routinely retract the bit to remove shavings and wood chips from the hole in order to prevent the
drill bit from binding.
Note: Feeding too slowly might cause the drill bit to turn in the chuck. Feeding too rapidly might stop the motor,
cause the belt to slip, force the workpiece loose, or break the drill bit. Practice with scrap material to get the feel of
the machine before attempting to do any drilling operation.
OPERATION
13
INSTALLING A DRILL BIT
1. With the switch OFF, open the chuck jaws (Fig. 23 - 1) using the chuck
key (Fig. 23 - 2). Turn the chuck key counterclockwise to open the jaws.
2. Insert the drill bit (Fig. 23 - 3) into the chuck far enough to obtain the
maximum gripping by the jaws, but not far enough to touch the spiral grooves
of the drill bit when the jaws are tightened.
3. Make sure the drill is centered in the chuck. Turn the chuck key (Fig. 23 -
2) clockwise to tighten the jaws.
POSITION THE TABLE AND WORKPIECE
Always place a piece of backup material (wood, plywood, etc.) on the table
underneath the workpiece . This will prevent splintering or blowout on the
underside of the workpiece as the drill bit breaks through. To keep the mate-
rial from spinning out of control, it must contact the left side of the column,
or be clamped (not included) to the table.
To prevent the workpiece or back-up material from spinning or rotating, you
MUST position it against the left side of the column (Fig. 24). Fig. 24

ASSEMBLY AND ADJUSTMENTS
USING THE LASER GUIDE
The laser guide should be adjusted prior to operation. To adjust the laser guide:
1. Mark an “X” on a piece of scrap wood.
2. Insert a small drill bit into the chuck and align its tip to the intersection of the lines of the “X.”
3. Secure the board to the table.
4. Turn on the laser switch and verify that the laser lines align with the “X” on the workpiece.
5. If the laser lines don’t align, loosen the set screws (Fig. 25 - 1) on each side of the head and rotate the laser
guides (Fig. 25 - 2) until the lines meet in the center of the “X.” Retighten the lock knobs to secure it in place.
ANGULAR “PLAY” OF THE SPINDLE (Fig. 27)
Move the spindle to the lowest downward position and
hold in place. Try to make the spindle revolve around its
axis while also moving it with a side motion. If there is too
much “play”, proceed as follows:
1. Loosen the lock nut.
2. Without obstructing the upward and downward motion
of the spindle, turn the screw clockwise to eliminate the
“play.” Note: A little bit of “play” is normal.
3. Tighten the lock nut.
Fig. 27
WARNING: Do not stare directly at the laser beam. Please observe all safety rules.
• Never aim the beam at a person or an object other than the workpiece.
• Do not project the laser beam into the eyes of others.
• Always make sure the laser beam is aimed at a workpiece that does not possess re-
ective surfaces, as the laser beam could project into your eyes or the eyes of others.

OPERATION
DRILLING SPEEDS
There are a few important factors to keep in mind when determining the best drilling speed: material type, hole
size, drill bit or cutter type, and desired quality level. Smaller drill bits require greater speed than larger drill bits.
Softer materials require greater speed than harder materials. See page 12 for recommended speeds for particular
materials.
DRILLING METAL
• Use metal-piercing twist drill bits.
• It is always necessary to lubricate the tip of the drill with oil to prevent overheating of the drill bit.
• All metal workpieces should be clamped down securely. Any tilting, twisting, or shifting causes a rough drill
hole, and increases the potential of drill bit breakage.
• Never hold a metal workpiece with your bare hands. The cutting edge of the drill bit may seize the workpiece
and throw it, causing serious injury. The drill bit will break if the metal piece suddenly hits the column.
• If the metal is flat, clamp a piece of wood under it to prevent turning. If it cannot be laid flat on the table, then it
should be blocked and clamped.
DRILLING WOOD
• Brad point bits are preferred. Metal piercing twist bits may be used on wood.
• Do not use auger bits. Auger bits turn so rapidly that they can lift the workpiece off of the table and whirl it
around.
• Always protect the drill bit by positioning the table so that the drill bit will enter the center hole when drilling
through the workpiece.
• To prevent splintering, feed the drill bit slowly right as the bit is about to cut through to the backside of the
workpiece.
• To reduce splintering and protect the point of the bit, use scrap wood as a backing or a base block under the
workpiece.
FEEDING THE DRILL BIT
• Pull down on the feed handles with only enough force to allow the drill bit to cut.
• Feeding too rapidly might stall the motor, cause the belt to slip, damage the workpiece, or break the drill bit.
• Feeding too slowly will cause the drill bit to heat up and burn the workpiece.
WARNING: For your safety, turn the switch off and remove the plug from the power supply before maintaining
or lubricating the drill press.
Vacuum sawdust or metal shavings that accumulate in and on the motor, pulley housing, table, and work surface.
Apply a light coat of paste wax to the column and table to help keep these surfaces clean and rust-free.
The ball bearings in the spindle and the V-belt pulley assembly are greased and permanently sealed. Pull the
spindle down and oil the spindle sleeve moderately every three months.
Lubricate the table bracket and locking knobs if they become difficult to use.
CAUTION: All servicing of the drill press should be performed by a qualified service technician.
