7. Be sure chuck key is removed from the chuck before
connecting to power source or turning power ON.
8. Adjust the table or depth stop to avoid drilling into the
table. Shut off the power, remove the drill bit, and clean
the table before leaving machine.
9. Do not connect tool to power source or operate until it is
completely assembled and installed according to the
instructions. If any part of your drill press malfunctions
or has been damaged or broken, do not operate until
the part is properly repaired or replaced.
SPECIFIC SAFETY RULES FOR DRILL PRESSES
10. Never place your fingers in a position where they could
contact the drill or other cutting tool if the workpiece
should unexpectedly shift.
11. Never use your hand to hold the object while drilling.
Always clamp the object tight on the work table or use a
drill vise to prevent accidental injury.
12. Never perform anyoperationbymoving the headortable
withrespect toone another. Do notturn themotor switch
ON or start any operation before checking that the head
and table lock handles are clamped tight to column and
head and table support collars are correctly positioned.
13. Before engaging the power switch ON, make sure the
belt guard is down and the chuck is installed properly.
14. Lock the motor switch OFF when leaving the drill press.
Do not perform layout, assembly, or set-up work on the
table while the cutting tool is rotating, switched on or
connected to a power source.

GROUNDING INSTRUCTIONS
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. 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 electrical shock. The conductor with the
insulationhavinganouter surface thatis greenwith orwithout
yellowstripesis theequipment-groundingconductor. Ifrepair
or replacement of the electric cord or plug is necessary, do
not connect the equipment-grounding conductor to a live
terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
This tool is intended for use on a circuit that has an outlet
like the one shown in Figure 1. It also has a grounding pin
like the one shown.
