general Power tool Safety

Warnings

WARNINg Read all safety warnings and instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term ″power tool″ in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

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

For technical questions, please call 1-800-444-3353. Page 2

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 suit-

able 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 equip-

ment. Always wear eye protection.

SKU 45338 For technical questions, please call 1-800-444-3353.

Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c. Prevent unintentional starting.

Ensure the switch is in the off-position before connecting to power source and/or battery pack, pick-

ing up or carrying the tool. Carry- ing 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.

f. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away

from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

g. If devices are provided for the connection of dust extraction and collection facilities, ensure these are

connected and properly used. Use of these devices can reduce dust- related hazards.

h. Only use safety equipment that has been approved by an appropri-

ate standards agency. Unapproved safety equipment may not provide adequate protection. Eye protection must be ANSI-approved and breathing protection must be NIOSH-ap-

Page 3

proved for the specific hazards in the work area.

4. Power tool use and care a. Do not force the power tool. use the correct power tool for your ap-

plication. The correct power tool will do the job better and safer at the rate for which it was designed.

b. Do not use the power tool if the switch does not turn it on and off.

Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power

tools. Such preventive safety mea- sures reduce the risk of starting the power tool accidentally.

d. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to oper-

ate the power tool. Power tools are dangerous in the hands of untrained users.

e. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired

before use. Many accidents are caused by poorly maintained power tools.

f. Keep cutting tools sharp and

clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g. use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions

and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5. Service a. Have your power tool serviced by a qualified repair person using only identical replacement parts.

This will ensure that the safety of the power tool is maintained.

This product is not a toy. Keep it out of reach of children.

10. People with pacemakers should consult their physician(s) before use.

Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure. In addition, people with pacemakers should:

• Avoid operating alone.

• Do not use with power switch locked on.

• Properly maintain and inspect to avoid electrical shock.

• Any power cord must be properly grounded. Ground Fault Circuit Interrupter (GFCI) should also be implemented – it prevents sustained electrical shock.

11. Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contains chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints

• Crystalline silica from bricks and cement or other masonry products

• Arsenic and chromium from chemically treated lumber

Your risk from these exposures var-

12. ies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. (California Health & Safety

Code § 25249.5, et seq.)

WARNING: Handling the cord on this product will expose you to lead, a chemical known to the State of

California to cause cancer, and birth defects or other reproductive harm.

WIRE CONNECtION:

Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

grounded tools: tools with three

Prong Plugs

SKU 45338

1. Tools marked with “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk

For technical questions, please call 1-800-444-3353. Page 6

3. of electric shock. (See 3-Prong Plug and Outlet.)

The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically

“live” terminal. (See 3-Prong Plug and Outlet.)

The tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the preceding illustration. (See 3-Prong

Plug and Outlet.)

Double Insulated tools: tools with two Prong Plugs

3.

4.

5.

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-Prong

Plug.)

6.

7.

Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration. (See

Outlets for 2-Prong Plug.)

Extension Cords

Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.

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.)

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.)

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.)

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.)

If you are using an extension cord outdoors, make sure it is marked with the suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.

Make sure the extension cord is properly wired and in good electrical con-

dition. 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.
