OPERATION
FOR YOUR PROTECTION
To avoid being pulled into the power
W A R N I N G
tool, do not wear loose clothing, gloves,
neckties, or jewelry. Always tie back long hair.
1. If any part of your drill press is missing, malfunctioning,
damaged or broken, stop operation immediately until that
part is properly repaired or replaced.
2. Never place your fingers in a position where they could
contact the drill bit or other cutting tool. The workpiece
may unexpectedly shift, or your hand could slip.
3. To prevent the workpiece from being torn from your hands,
thrown, spun by the tool, or shattered, always properly
support your workpiece as follows:
a. Always position BACKUP MATERIAL (used beneath
workpiece) so that it contacts the left side of the
column, or use the fence provided and a clamp to brace
the workpieces.
b. Whenever possible, position the workpiece to contact
the left side of the column. If it is too short or the table is
tilted, use the fence provided or clamp solidly to the
table, using the table slots.
c. When using a drill press vise, always fasten it to the table.
d. Never do any work freehand (hand-holding the
workpiece rather than supporting it on the table), except
when polishing.
e. Securely lock the head and support to the column, the
table arm to the support, and the table to the table arm,
before operating the drill press.
f. Never move the head or the table while the tool is
running.
g. Before starting an operation, jog the motor switch to
make sure the drill or other cutting tool does not wobble
or cause vibration.
h. If a workpiece overhangs the table so it will fall or tip if
not held, clamp it to the table or provide auxiliary support.
i. Use fixtures for unusual operations to adequately hold,
guide, and position workpiece.
j. Use the SPINDLE SPEED recommended for the specific
operation and workpiece material. Check the panel on
the inside pulley cover or the chart below for drilling
speed information. For accessories, refer to the
instructions provided with each accessory.
4. Never climb on the drill press table, it could break or pull
the entire drill press down on you.
5. Turn the power switch "OFF", and put away the switch key
when leaving the drill press.
6. To avoid injury from thrown work or tool contact, do not
perform layout, assembly, or setup work on the table while
the cutting tool is rotating.

POSITIONING THE TABLE AND WORKPIECE
(FIG. AA AND BB)
1. Lock the table (1) to the column (2) at a position so the tip
of the drill bit (3) is just above the top of the workpiece (4).
2. ALWAYS place a BACK-UP MATERIAL (scrap wood) on
the table beneath the workpiece. This will prevent
splintering or heavy burring on the underside of the
workpiece. To keep the back-up material from spinning, it
MUST be positioned against the LEFT side of the column.
3. For a small piece that cannot be clamped to the table, use
a drill press vise (optional accessory).
To prevent the workpiece or backup
W A R N I N G
material from being thrown 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,
or use the fence provided with the drill press to brace the
workpiece. Failure to secure the workpiece could result in
personal injury.

A drill press vise MUST be clamped or
W A R N I N G
bolted to the table to avoid injury from a
spinning workpiece, or damaged vise or bit parts.
Remove the drill press fence when it interferes with other
drill press accessories.
