1.Work area safety
a.Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b.Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c.Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2.Electrical safety
a.Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with grounded power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b.Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
c.Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d.Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e.When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f.If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of
a GFCI reduces the risk of electric shock.
3.Personal safety
a.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.
b.Use personal protective equipment. Always wear eye protection. Safety equipment such as dust mask,
c.Prevent unintentional starting. Ensure the switch is in the off- position before connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
d.Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e.Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.

Double Insulated Tools: Tools
with Two Prong Plugs
Outlets for
1.Tools marked ???Double Insulated??? do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters
Laboratories, Inc., the Canadian
Standard Association, and the
National Electrical Code. (See
Outlets for
2.Double insulated tools may be used in either of the 120 volt outlets shown
in the preceding illustration. (See
Outlets for
Extension Cords
1.Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.
2.As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage.
(See Table A.)
3.The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Table A.)
4.When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required.
(See Table A.)
5.If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.)
6.If you are using an extension cord outdoors, make sure it is marked with the suffix
7.Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged
extension cord or have it repaired by a qualified electrician before using it.
8.Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.

Work Piece and Work Area Set Up
1.Designate a work area that is clean and
2.Route the power cord along a safe route to reach the work area without creating a tripping hazard or exposing the power cord to possible damage. The power cord must reach the work area with enough extra length to allow free movement while working.
3.Secure loose work pieces using a vise or clamps (not included) to prevent movement while working.
4.There must not be objects, such as utility lines, nearby that will present a hazard while working.
General Operating Instructions
1.Make sure the trigger is released and not locked on, then plug the
Power Cord into a suitable outlet.
2.Press the Direction Switch of the
Trigger to determine the rotation direction. Press to the left side for clockwise rotation. Press to the right side for counterclockwise rotation.
5.Use only
6.Use firm pressure when drilling, but do not press too hard. Too much pressure will cause the bit to overheat, may cause the bit to bend or break, cause undue strain on the tool, and may damage the work
piece. Pressing too hard may stall the motor.
7.If the motor stalls, release the Trigger immediately to prevent damage to the tool.
8.Only drill in a straight line. Bending or twisting the bit while drilling may cause the bit to bend or break and may damage the work piece.
9.Back off your pressure if you are about to penetrate the other side of the work piece.
10.Keep the motor running when pulling the bit out of a completed hole to prevent the bit from jamming.
Metal Drilling
1.Use high speed steel, carbide, TiN coated, or specialty bits for metal drilling.
2.Secure the work piece to keep it from moving during the drilling operation.
3.To make starting the hole easier, use a punch to create a dimple at the hole center.
4.Unless drilling into cast iron or brass use a cutting lubricant.
5.Start by drilling slowly to keep the bit from moving away from your starting point.
6.As the hole is established, increase tool speed. Do not go so fast or use so much pressure that the bit heats up. This can damage the bit and create an irregular hole. For hard metal, use cutting oil to keep the bit cool.
7.Since drilling in metal is a slow operation, you may lock the Trigger in the ON position to maintain a constant speed and reduce fatigue.
8.When drilling large holes in metal, start by drilling a smaller pilot hole, then using a larger bit for the final size hole.
Wood Drilling
1.Use high speed bits or bits specially designed for wood drilling, such as brad point, spade bits, forstner bits, etc.
2.Secure the work piece to keep it from moving during the drilling operation.
3.Start by drilling slowly to keep the bit from moving away from your starting point. Increase speed as the hole is established.
4.To prevent or reduce ???break out??? when the bit penetrates the work piece, clamp a piece of scrap material to the back of the work piece.
5.Do not lock the Trigger in the ON position, as the bit can easily jam in wood and the motor must be stopped quickly.
