WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS

Failure to follow all instructions listed below may result in

electric shock, fire, and/or serious injury.

SAVE THESE INSTRUCTIONS

WORK AREA

1. Keep your work area clean and well lit. Cluttered benches and dark areas

invite accidents.

2. 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.

3. Keep bystanders, children, and visitors away while operating a power tool.

Distractions can cause you to lose control. Provide barriers or shields as needed. Children should never be in the work area.

PERSONAL SAFETY

1. Stay alert. Watch what you are doing, and use common sense when oper-

ating a power tool. Do not use a power tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operat-

ing power tools may result in serious personal injury.

2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair.

Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

before performing any

4. Remove adjusting keys or wrenches before turning the Impact Wrench on.

A wrench or a key that is left attached to a rotating part of the machine may result in personal injury.

5. Do not overreach. Keep proper footing and balance at all times. Proper

footing and balance enables better control of the power tool in unexpected situations.

TOOL USE AND CARE

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

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

2. Do not use the Impact Wrench if the Stop Button (103) does not turn it on

or off. Any tool that cannot be controlled with its Stop Button is dangerous and must be replaced.

3. Store idle tools out of reach of children and other untrained persons. Tools

are dangerous in the hands of untrained users.

4. Maintain tools with care. Properly maintained tools are less likely to malfunc-

tion and are easier to control. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.

5. Check for misalignment or binding of moving parts, breakage of parts, and

any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly main-

tained tools.

or maintenance performed by unqualified personnel could result in a risk of injury.

2. When servicing a tool, use only identical replacement parts. Follow

instructions in the manual. Use of unauthorized parts or failure to follow maintenance instructions

may create a risk of electric shock or injury.
