at a very high speed in the direc­tion of rotation. This Can Cause
Serious Injury. To reduce the pos­sibility of injury from thrown work:

- Clamp the workpiece firmly to the
table whenever possible.

- Buffing or sanding wheels or
drums should be contacted on the
side moving away from you, not
the side moving toward you.

- Use only recommended accesso­ries and follow the instructions
supplied with the accessory.

Think Safety

WARNING: Do not allow famil-

iarity (gained from frequent use of
your drill press) to become com­monplace. Always remember that a
careless fraction of a second is suf­ficient to inflict severe injury.

Plan Your Work

• Don’t force the tool. It will do the job
better and safer at the rate for which
it was designed.

• Use the right tool. Don’t force tool or
attachment to do a job it was not
designed to do.

• If any part of your drill press is miss­ing, malfunctioning, has been dam­aged or broken...such as the motor
switch, or other operating control, a
safety device or the power cord, turn
the drill press off and unplug it until
the particular part is properly
repaired or replaced.

• Never place your fingers in a posi­tion where they could contact the
drill or other cutting tool if the work­piece should unexpectedly shift or
your hand should slip.

• Keep guards in place and in working
order.

• To reduce the risk of injury from
parts thrown by the spring, follow
instructions exactly as given and

shown in adjusting spring tension of
quill.

• To prevent the workpiece from being
torn from your hands, spinning of
the tool, shattering the tool or being
thrown, always properly support
your work so it won’t shift or bind on
the tool:

- Always position backup material

(use beneath the workpiece) to
contact the left side of the column.

- Whenever possible, position the

workpiece to contact the left side of
the column - If it is too short or the
table is tilted, clamp solidly to the
table. Use table slots or clamping
ledge around the outside edge of
the table.

- When using a drill press vise,

always fasten it to a table.

- Never do any work “Freehand”

(hand holding workpiece rather
than supporting it on the table),
except when polishing.

- Securely lock head to column,

table support to column and table
to table support before operating
drill press.

- Never move the head or table

while the tool is running.

- Before starting the operation, jog

the motor switch to make sure the
drill or other cutting tool does not
wobble or cause vibration.

- If a workpiece overhangs the table

such that it will fall or tip if not held,
clamp it to the table or provide aux­iliary support.

- Use fixtures for unusual operations

to adequately hold, guide and posi­tion workpiece.

110-120 Volt, 60 Hz. Tool
Information

NOTE: The plug supplied on your tool

may not fit into the outlet you are planning
to use. Your local electrical code may
require slightly different power cord plug
connections. If these differences exist
refer to and make the proper adjustments
per your local code before your tool is
plugged in and turned on.

In the event of a malfunction or break­down, grounding provides a path of least
resistance for electric current to reduce
the risk of electric shock. This tool is
equipped with an electric cord having an
equipment grounding conductor and a
grounding plug, as shown. 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 qualified electrician.

Improper connection of the equipment
grounding conductor can result in a risk of
electric shock. The conductor with insula­tion having an outer surface that is green
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 equipment­grounding conductor to a live terminal.

If the grounding instructions are not com­pletely understood, or if you are in doubt
as to whether the tool is properly
grounded check with a qualified electri­cian or service personnel.

WARNING: If not properly
grounded, this tool can cause an
electrical shock, particularly when
used in damp locations, in proximity
to plumbing, or outdoors. If an elec­trical shock occurs there is the
potential of a secondary hazard,
such as your hands to hit the cut­ting tool.

a. Motor Is Overloaded - Overloading

can occur if you feed too rapidly or
make too many start/stops in a short
time.

b. Line voltages should not be more than

10% above or below the nameplate
voltage. For heavy loads, however, the
voltage at motor terminals must equal
the voltage specified for your model.

c. Improper or dull drill bit is used.

4. Most motor troubles may be traced to
loose or incorrect connections, overload,
low voltage (such as small size wire in
