GENERAL SAFETY RULES
WARNING! Read and understand all instructions. Failure to follow all instructions listed below may result
in electric shock, fire and/or serious injury.
WARNING! The warnings, cautions, and instructions discussed in this instruction manual cannot
cover all possible conditions or situations that could occur. It must be understood by the operator
that common sense and caution are factors which cannot be built into this product, but must be
supplied by the operator.
SAVE THESE INSTRUCTIONS
WORK AREA
• Keep work area clean, free of clutter and well lit. Cluttered and dark work areas can cause accidents.
• Do not use your tool where there is a risk of causing a fire or an explosion; e.g. in the presence of
flammable liquids, gasses, or dust. Power tools create sparks, which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control, so visitors should remain at a safe distance from the work area.

2
• Be aware of all power lines, electrical circuits, water pipes and other mechanical hazards in your work
area, particularly those hazards below the work surface hidden from the operator's view that may be
unintentionally contacted and may cause personal harm or property damage.
• Be alert of your surroundings. Using power tools in confined work areas may put you dangerously close to
cutting tools and rotating parts.
ELECTRICAL SAFETY
WARNING! Always check to ensure the power supply corresponds to the voltage on the rating plate.
• Do not abuse the cord. Never carry a portable tool by its power cord, or yank tool or extension cords from
the receptacle. Keep power and extension cords away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords may cause a fire and increase the risk of electric shock.
• Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes
and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded.
• Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will
fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still doesn't
fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an
increase risk of electric shock if your body is grounded.
• When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.” These cords
are rated for outdoor use and reduce the risk of electric shock.
• Extension Cord Use:
A. Use only 'Listed' extension cords. If used outdoors, they must be marked “For Outdoor Use.” Those
cords having 3-prong grounding type plugs and mating receptacles are to be used with grounded tools.
B. Replace damaged or worn cords immediately.
C. Check the name plate rating of your tool. Use of improper size or gauge of extension cord may cause
unsafe or inefficient operation of your tool. Be sure your extension cord is rated to allow sufficient current
flow to the motor. For the proper wire gauge for your tool, see chart.
CHART FOR MINIMUM WIRE SIZE OF EXTENSION CORD:
If in doubt, use larger cord. Be sure to check voltage requirements of the tool to your incoming power source.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
• Do not let your fingers touch the terminals of plug when installing to or removing from the outlet.
• Ground fault circuit interrupters. If work area is not equipped with a permanently installed Ground Fault
Circuit Interrupter outlet (GFCI), use a plug-in GFCI between power tool or extension cord and power receptacle.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a
power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention
while operating power tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. Air vents often
cover moving parts and should be avoided.
• Use safety apparel and equipment. Use safety goggles or safety glasses with side shields which comply
with current national standards, or when needed, a face shield. Use as dust mask in dusty work conditions.
This applies to all persons in the work area. Also use non-skid safety shoes, hardhat, gloves, dust collection
systems, and hearing protection when appropriate.

3
• Avoid accidental starting. Do not carry the power tool with your finger on the switch. Ensure the switch is in
the off position before plugging tool into power outlet. In the event of a power failure, while a tool is being
used, turn the switch off to prevent surprise starting when power is restored.
• Do not overreach. Keep proper footing and balance at all times.
• Remove adjusting keys or wrenches before connecting to the power supply or turning on the tool. A
wrench or key that is left attached to a rotating part of the tool may result in personal injury.
• 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.
• 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 climb on or allow others to climb on the drill press table; it could break or pull the entire drill
press down.
• Turn the motor Switch OFF and put away the Switch Key when leaving the drill press.
• 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.
TOOL USE AND CARE
• Do not force the tool. Tools do a better and safer job when used in the manner for which they are designed.
Plan your work, and use the correct tool for the job.
• Never use a tool with a malfunctioning switch. Any power tool that cannot be controlled with the switch is
dangerous and must be repaired by an authorized service representative before using.
• Disconnect power from tool and place the switch in the locked or off position before servicing, adjusting,
installing accessories or attachments, or storing. Such preventive safety measures reduce the risk of starting
the power tool accidentally.
• Secure work with clamps or a vise instead of your hand to hold work when practical. This safety precaution
allows for proper tool operation using both hands.
• Store idle tools. When tools are not is use, store them in a dry, secure place out of the reach of children.
Inspect tools for good working condition prior to storage and before re-use.
• Use only accessories that are recommended by the manufacturer for your model. Accessories that may be
suitable for one tool may create a risk of injury when used on another tool.
• Keep guards in place and in working order.
