5. 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.
PERSONAL SAFETY
1. 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.
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.
3. 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.
4. 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.
5. Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the tool in unexpected situations.
6. Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
7. Use certified safety equipment. Eye protection equipment should comply
with ANSI Z87.1 standards, hearing equipment should comply with ANSI S3.19
standards, and dust mask protection should comply with MSHA/NIOSH certified
respirator standards.
8. Never touch wheel immediately after use. It may be extremely hot.
TOOLS USE AND CARE
1. 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 unstable
and may lead to loss of control.
2. 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.
3. 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.
4. Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive
safety measures reduce the risk of starting the tool accidentally.
5. Store idle tools out of reach of children and other untrained persons.
Tools are dangerous in the hands of untrained users.
6. Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools, with sharp cutting edges are less likely to bind and are easier to
control.
7. 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
maintained tools.
8. Use only accessories that are recommended by the manufacturer for
your model. Accessories that may be suitable for one tool may become
hazardous when used on another tool.
SERVICE
1. Tool service must be performed only by qualified repair personnel.
Service 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 Maintenance Section of this manual. Use of unauthorized
parts or failure to follow Maintenance Instructions may create a risk of electric
shock or injury.
