9. When operating a power tool outside, use an outdoor extension cord marked “W-
A” or “W”. These extension cords are rated for outdoor use, and reduce the risk of
electric shock.
Personal Safety
10. Stay alert. Watch what you are doing, and use common sense when operating 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 operating power tools may result
in serious personal injury.
11. 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.
12. Avoid accidental starting. Be sure the Power Switch is off before plugging in.
Carrying power tools with your finger on the Power Switch, or plugging in power tools
with the Power Switch on, invites accidents.
13. Remove adjusting keys or wrenches before turning the power tool on. A wrench
or a key that is left attached to a rotating part of the power tool may result in personal
injury.
14. Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control in unexpected situations.
Tool Use and Care
15. Use clamps (not included) or other practical ways 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.
16. 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.
17. Do not use the power tool if the Power Switch does not turn it on or off. Any tool
that cannot be controlled with the Power Switch is dangerous and must be replaced.
18. Disconnect the Power Cord 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.
19. Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
20. Maintain with care. Keep cutting tools sharp and clean. Properly maintained tools
with a sharp cutting edge are less likely to bind and are easier to control. Do not use a
damaged tool. Tag damaged tools “Do not use” until repaired.
