DRILL PRESS SAFETY
22. USE RECOMMENDED SPEED for drill accessory and
workpiece material. SEE INSTRUCTIONS that come with the
accessory.
23. WHEN DRILLING large diameter holes, clamp the work-
piece firmly to the table. Otherwise, the bit may grab and spin
the workpiece at high speed. DO NOT USE fly cutters or mul-
tiple-part hole cutters, as they can come apart or become un-
balanced in use.
24. MAKE SURE the spindle has come to a complete stop
before touching the workpiece.

ELECTRICAL REQUIREMENTS AND SAFETY

IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides a path of least resistance for electric cur-
rents and reduces the risk ofelectric shock. This tool is equipped
with an electrical cord that has an equipment-grounding con-
ductor and a grounding plug. The plug must be plugged into a
matching receptacle 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
receptacle, have the proper receptacle installed by a qualified
electrician.
IMPROPER CONNECTION of the equipment grounding con-
ductor can result in risk of electric shock. The conductor with
the green insulation (with or without yellow stripes) is the
equipment grounding conductor. If repair or replacement of
the electrical cord or plug is necessary, DO NOT connect the
equipment grounding conductor to a live terminal.
CHECK with a qualified electrician or service person if you do
not completely understand the grounding instructions, or if you
are not certain the tool is properly grounded.
USE ONLY THREE-WIRE ExTENSION CORDS THAT HAVE
THREEPRONGED GROUNDING PLUGS WITH THREE-POLE
RECEPTACLES THAT ACCEPT THE TOOL'S PLUG. REPAIR OR
REPLACE DAMAGED OR WORN CORDS IMMEDIATELY.
GUIDELINES FOR ExTENSION CORDS
Make sure your extension cord is in good condition. Use an
extension cord heavy enough to carry the current your product
will draw. An undersized cord will cause a drop in line volt-
age resulting in loss of power, overheating and burning out of
the motor. The table on the right shows the correct size to use
depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge num-
ber, the heavier the cord.
Be sure your extension cord is properly wired and in good
condition. Always replace a damaged extension cord or have
it repaired by a qualified person before using it. Protect exten-
sion cords from sharp objects, excessive heat and damp or wet
areas.
25. TO AVOID INJURY from accidental starting, always turn
the switch OFF and unplug the drill press before installing or
removing any accessory or attachment or making any adjust-
ment.
26. KEEP GUARDS IN PLACE and in working order.
27. USE ONLY SELF-EJECTING TYPE CHUCK KEY as pro-
vided with the drill press.
Use a separate electrical circuit for your tools. This circuit must
not be less than #12 wire and should be protected with a 15
Amp time lag fuse. Before connecting the motor to the power
line, make sure the switch is in the OFF position and electric
current is rated the same as the current stamped on the motor
nameplate. Running at a lower voltage will damage the motor.
This drill press is intended for use on a circuit that has a re-
ceptacle like the one illustrated below. This shows a 3-prong
electrical plug and receptacle that has a grounding conductor.
The Canadian Electrical Code prohibits the use of adapters.
CAUTION In all cases, make certain the receptacle
is properly grounded. If you are not sure, have a
qualified electrician check the receptacle.
WARNING
This drill press is for indoor use only. Do not expose
to rain or use in damp locations.
