SKU 44836 PAGE 4

10. CAUTION: Some woods contain preservatives such as copper chromium arsenate

(CCA) which can be toxic. When drilling these materials extra care should be taken
to avoid inhalation and minimize skin contact.

11. ALLOW THE DRILL BIT TO SPIN UP TO FULL SPEED BEFORE DRILLING INTO
THE WORKPIECE. When turning off the Drill Press, allow the drill bit to spin down
and stop on its own. Do not press the drill bit against the workpiece to stop it.

12. DO NOT FORCE THE DRILL BIT INTO THE WORKPIECE WHEN DRILLING.
Apply moderate downward pressure, allowing the drill bit to cut without being forced.

13. NEVER ATTEMPT TO REMOVE MATERIAL STUCK IN THE MOVING PARTS OF

THE DRILL PRESS WHILE THE DRILL PRESS IS PLUGGED IN AND RUNNING.

14. THE DRILL BIT WILL BECOME HOT WHILE DRILLING. Allow the drill bit to
completely cool before touching.

workbench capable of supporting the weight of the Drill Press, accessories, and the
material being drilled.

2. The Base (part #4A) of the Drill Press features four 1/2” mounting holes.

(See Assembly Diagram A.)

3. With assistance, set the Drill Press in the desired position on the workbench.

4. Using the mounting holes on the Base (part #4A) as a template, mark the 1/2” holes
to be drilled through the top of the workbench.

5. With assistance, set the Drill Press aside.

6. Use a 1/2” drill bit to drill the four holes through the workbench. Reposition the Drill
Press on the workbench and secure the Drill Press to the workbench, using four 1/2”

Bolts of appropriate length, Washers and Locknuts (not provided).

To Install/Reposition The Drive Belts:

1. The Drill Press features 12 speed selections from which to choose.

2. The two V-Belts (parts #21C, 26C), when positioned on the three Pulleys
(parts #3C, 28C, 19C), will determine the speed at which the Drill Press will run.

(See Assembly Diagram C and Figure B.)

3. To install or reposition the two V-Belts (parts #21C, 26C), release the two Motor
Adjusting Knobs (part #12B) which are located on both sides of the Head Assembly
(part #1B). (See Assembly Diagram B.)

4. Lubricate the Idler Pivot Shaft (part #29C) and Center Pulley (part #28C) with a light
grease, and install the Pivot Shaft in the hole located between the Motor Pulley
(part #3C) and Spindle Pulley (part #19C). Then, insert the Center Pulley onto the
Idler Pivot Shaft. (See Assembly Diagram C.)

5. Consult the
the V-Belts (parts #21C, 26C) in the positions corresponding to the drill speed
desired.

6. Secure the V-Belts (parts #21C, 26C) in position by locking the two Motor Adjusting
Knobs (part #12B). (See Assembly Diagrams B and C.)

To Obtain The Proper Cutting Speeds:

1. Factors which determine the best speed to use in the Drill Press are:

A. The kind of material being drilled.
B. The size of the hole.
C. The quality of cut desired.

2. Generally, in soft material the speed should be higher than for hard materials. The
following guide indicates the proper Drill Press speed (RPM) for a given drill bit size
and the material being drilled. (See Figure C.)

SKU 44836 PAGE 8

To Adjust The Table:

1. The Table (part #9A) may be adjusted in 4 directions.

2.

3.

To raise or lower the Table

Crank (part #6A) clockwise to raise the Table and counterclockwise to lower the
Table. When the desired height of the Table has been reached, secure the Table in
place by locking the Table Clamp.

(See Assembly Diagram A and Figure D.)

To move the Table to the right or left

move the Table left or right to the desired position. Once the desired position
has been set, secure the Table in place by locking the Table Clamp. (See Figure D.)

, release the Table Clamp (part #11A), and turn the

, release the Table Clamp (part #11A) and

To Adjust The Spindle Depth:

1. Located on the Hub Pinion (part #18B) is a Depth Lock Screw (part #14B) and a
Depth Stop Ring w/Scale (part #15B), with depth settings in both inches and metric
units. (See Assembly Diagram B and Figure E.)

2. To set a drilling depth, insert and secure a drill bit in the Chuck (part #8C).

3. Lower the drill bit (with the power OFF) until it contacts the material to be drilled, and
hold in that position.

4. Loosen the Depth Lock Screw (part 14B), and turn the Depth Stop Ring w/Scale
(part #15B) so that the measurement for the depth of hole desired is in line the
Stop Pin (part #19B). Lock the Depth Stop Ring w/Scale in position, using the
Depth Lock Screw (part 14B). (See Figure E.)

SKU 44836 PAGE 9

5. The Drill Press is now set to drill holes to your pre-determined depth, provided the
surface of the workpiece is flat and level. You may also drill a series of holes to the
same depth.

To Operate The Drill Press:

1. Before starting the Drill Press, make
sure all adjustments are properly made
and all of the guards are in place.

2. Insert the drill bit about 1” into the jaws
of the Chuck (part #8C). Make sure the
jaws of the Chuck do not touch the
flutes of the drill bit. Before tightening
the Chuck, make sure the drill bit is
centered within the jaws of the Chuck.

3. Make sure the workpiece is securely
clamped, held in a drill press vise, or
bolted to the Drill Press Table (part #9A).
Never hold the workpiece with bare
hands as personal injury and/or damage
to the Drill Press may occur.

4. When drilling completely through
wooden material, place a piece of scrap
wood between the workpiece and the

Table to prevent splintering on the underside of the workpiece when the drill bit
breaks through. The scrap wood should make contact with the left side of the
Column (part #1A) (See Figure F.)

SKU 44836 PAGE 10

5. Set the depth of drill bit travel so that the drill bit cannot come into contact with
the Table (part #9A), or align the Table so that the hole in its center is in line with the
drill bit.

6.

The Drill Press is now ready to operate.

CLEANING, INSPECTION, AND MAINTENANCE

1.

2. Do not introduce water into the electric motor through the motor vents.

3. Do not use solvents to wipe off the Drill Press, as damage may result.

4. With a brush or soft cloth, remove all the metal shavings/sawdust from the Drill

5. If necessary, wipe with a damp cloth. You may use a mild detergent.

6. Once clean, lubricate all moving parts, including the Column (part #1A) with a light

7. When storing, keep the Drill Press covered with a cloth cover.

Caution:

Press.

oil.

Always disconnect the Drill Press from its electrical power supply source

8. Before each use, inspect the general condition of the Drill Press. Inspect the switch,
power plug and cord assembly, and extension cord (if used) for damage.

9. Check for loose screws, misalignment, binding of moving parts, broken, cracked, or
improper mounting of drill bit, broken parts and any other condition that may affect
its safe operation.

10. Check the V-Belts (parts #21C, 26C) for wear, and replace if frayed or damaged in
any way.

11. Blow out any dust that may have accumulated in the motor fan.

12. If abnormal noise or vibration occurs, turn off the Drill Press immediately.

13. If a problem is apparent refer to Figure G, and if necessary have the problem
corrected by a qualified technician before further use.
Do not use damaged equipment.. (See Figure G on Page 12.)
