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. Refer to "Recommended sizes of Extension Cords" in
the Accessory section of this manual.
Personal Safety
Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use tool while 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 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. Keep handles
dry, clean and free from oil and grease.
Avoid accidental starting. Be sure switch is "OFF" before plugging in.
Carrying tools with your finger on the switch or plugging in tools that have the
switch "ON" invites accidents.
Remove adjusting keys or wrenches before turning the tool "ON". A
wrench or a key that is left attached to a rotating part of the tool may result in
personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the tool in unexpected situa-
tions.
Use safety equipment. Operators and bystanders must always wear eye
protection meeting the requirements of ANSI Z87.1. Appropriate respira-
tory protection, non-skid safety shoes, hard hat, or hearing protection must
be used as conditions warrant.
Tool Use and Care
Use clamps or other practical way to secure and support the workpiece
to a stable platform. Holding the work by hand or against your body is unsta-
ble and may lead to loss of control.
Do not force 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.
Do not use tool if switch does not turn it "ON" or "OFF". Any tool that
cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source before making any adjust-
ments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
Store idle tools out of reach of children and other untrained persons.
Tools are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools, with sharp cutting edges are less likely to bind and are eas-
ier to control. Any alteration or modification is a misuse and may result in a
dangerous condition.
Check for misalignment or binding of moving parts, breakage of parts,
and any other condition that may affect the tools operation. If damaged,
have the tool serviced before using. Many accidents are caused by poorly
maintained tools. Develop a periodic maintenance schedule for your tool.
Use only accessories that are recommended by the manufacturer for
your model. Accessories that may be suitable for one tool, may become haz-
ardous when used on another tool.
Service
Tool service must be performed only by qualified repair personnel. Ser-
vice or maintenance performed by unqualified personnel could result in a risk
of injury. For example: internal wires may be misplaced or pinched, safety
guard return springs may be improperly mounted.
When servicing a tool, use only identical replacement parts. Follow
instructions in the Maintenance section of this manual. Use of unautho-
rized parts or failure to follow Maintenance Instructions may create a risk of
electric shock or injury. Certain cleaning agents such as gasoline, carbon
tetrachloride, ammonia, etc. may damage plastic parts.
Angle Grinder Safety Rules
Always use proper guard with grinding wheel. A guard helps protects oper-
ator from broken wheel fragments. When using grinding wheel attachments,
the guard must always be securely attached to the tool and positioned for
maximum safety, so the least amount of wheel is exposed toward the operator.
Accessories must be rated for at least the speed listed on the tool warn-
ing label. Wheels and other accessories running over rated speed can fly
apart and cause injury. Grinding wheels or any other accessory must have a
