BASIC OPERATION INSTRUCTIONS
To get the best results and minimize the likelihood of personal
injury, follow these instructions for operating the drill press.
WARNING:
For your own safety, always observe the SAFETY IN-
STRUCTIONS listed here and on pages 3, 4 and 5 of
the Operator's Manual.
YOUR PROTECTION
WARNING:
To avoid being pulled into the power tool, do not wear
loose clothing, gloves, neckties, or jewellery. 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. Avoid injury from parts being thrown by the spring tension
of the quill.
4. To prevent the workpiece from being torn from your hands,
thrown, spun by the tool, or shattered, always properly sup-
port your workpiece as follows:
a. Always position backup material (used beneath work-
piece) so that it contacts the left side of the column, and a
clamp to brace a small workpiece.
b. Whenever possible, position the workpiece to contact
the left side of the column. If it is too short or the table is
tilted, or clamp solidly to the table, using the table slots.
c. When using a drill press vice, always fasten it to the
table.
d. Never do any work freehand (hand-holding the work-
piece rather than supporting it on the table).
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 run-
ning.
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 sup-
port.
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 pro-
vided with each accessory.
5. Never stand on the drill press table, it could break or pull
the entire drill press down on you.
6. Turn the motor switch OFF, and put away the switch key
when leaving the drill press.
7. To avoid injury from thrown work or tool contact, do not
perform layout, assembly, or set up work on the table while
the cutting tool is rotating.
