WORK AREA SAFETY

• Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

• Do not operate power tools in explosive atmo-

spheres, such as in the presence of ammable liquids, gases 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.

ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodied plugs and matching outlets will

reduce risk of electric shock.

• Avoid body contact with earthed or grounded

surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric

shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the

risk of electric shock.

• 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.

• 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.

• If operating a power tool in a damp location is

unavoidable, use a ground fault circuit interrupter

(GFCI) protected supply. Use of an GFCI reduces

the risk of electric shock.

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 inuence of drugs, alcohol or medication. A moment of inattention while operating power tools

may result in serious personal injury.

• Use personal protective equipment. Always

wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions

will reduce personal injuries.

• 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 nger on

the switch or energizing power tools that have the

switch on invites accidents.

• 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.

• Do not overreach. Keep proper footing and

balance at all times. This enables better control

of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair

can be caught in moving parts.

• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

• Do not let familiarity gained from frequent use of tools allow you to become complacent and

ignore tool safety principles. A careless action can

cause severe injury within a fraction of a second.

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct power tool

will do the job better and safer at the rate for which it was designed.

•

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.

• Disconnect the plug from the power source and/

or remove the battery pack, if detachable, from the power tool before making any adjustments,

changing accessories, or storing power tools.

Such preventive safety measures reduce the risk of

starting the power tool accidentally.

• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands

of untrained users.

• Maintain power tools and accessories. 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 ac-

cidents are caused by poorly maintained power tools.

• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

• 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.

• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and

grasping surfaces do not allow for safe handling and

control of the tool in unexpected situations.

SERVICE

• Have your power tool serviced by a qualied

repair person using only identical replacement parts. This will ensure that the safety of the power

tool is maintained.

SPECIFIC SAFETY RULES FOR

IMPACT WRENCH

• Hold the power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring or its own cord. Fasteners contacting a “live” wire may make

exposed metal parts of the power tool “live” and could

give the operator an electric shock.

• Wear ear protectors when impact drilling. Expo-

WARNING

sure to noise can cause hearing loss.

• Use only sockets and other accessories speci

cally designed for use on impact wrenches and drivers. Other sockets and accessories might shatter

or break causing injury.

• Maintain labels and nameplates. These carry

important information. If unreadable or missing,

contact a MILWAUKEE service facility for a free

replacement.

•

construction activities contains chemicals known to cause cancer, birth defects or other reproductive

harm. Some examples of these chemicals are:

• lead from lead-based paint

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated

lumber.

Your risk from these exposures varies, 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

lter out microscopic particles.

Some dust created by power sanding, sawing, grinding, drilling, and other

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. Refer to the table shown to determine the required minimum wire size.

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.

When using more than one extension cord to make up the total length, be sure each cord contains at

least the minimum wire size required. 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 wire size.

Guidelines for Using Extension Cords

• If you are using an extension cord outdoors, be sure

it is marked with the sufx “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.

• Be sure your extension cord is properly wired

and in good electrical condition. Always replace a

damaged extension cord or have it repaired by a

qualied person before using it.

• Protect your extension cords from sharp objects,

excessive heat and damp or wet areas.

GROUNDING

electric shock. Check with a qualied electrician if you are in doubt as to whether the outlet is

properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it

repaired by a MILWAUKEE service facility before use. If the plug will not t the outlet, have a proper outlet installed by a qualied electrician.

Grounded Tools (Three-Prong Plugs)

Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug

must be connected to a properly grounded outlet (See Figure A). 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 of electric shock.

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.

Your 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 Figure A.

Double Insulated Tools (Two-Prong Plugs)

Tools marked “Double Insulated” do not require

grounding. They have a special double insulation system which satises OSHA requirements and

complies with the applicable standards

of Underwriters Laboratories, Inc., the

Canadian Standard Association and

the National Electrical Code. Double

Insulated tools may be used in either

of the 120 volt outlets shown in Figures B and C.

Improperly connecting the grounding wire can result in the risk of
