GENERAL SAFETY RULES USA0021
(For All Tools)
WARNING! Read and understand all instructions. Failure
tofollow all instructions listed below, may result
in electric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keep your work area cleanand well lit. Clutteredbenches and dark areas invite
accidents.
2. Donotoperate powertools in explosiveatmospheres, 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.
Electrical Safety
4. DoubleInsulatedtools are equipped with a polarized plug (oneblade iswider
than the other.) This plug will
fit in a polarized outlet only one way. If the
plug does not fit fully in the outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install a polarized outlet. Do not change
the plug
in any way. Double insulation El eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoid body contact withgrounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if
your body is
grounded.
6. Donotexpose powertoolstorainor wetconditions. Water entering a power
tool will increase the risk of electric shock.
7. Do notabuse the cord. Never use the cordtocarry thetoolsor pullthe plug
from anoutlet. Keepcordaway fromheat, oil, sharp edges or movingparts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8. When operating apower tooloutside, usean outdoor extension cord marked
"W-A' or "W." These cords are rated for outdoor use and reduce the risk
of electric shock.
Personal Safety
9. Stay alert, watchwhat youaredoing and usecommon sense whenoperating
a power tool.
Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A moment of inattention while operating powertools
may result
in serious personal injury.
IO. Dressproperly. Do notwear loose clothing orjewelry. Contain long hair. Keep
your hair, clothing, andglovesawayfrom movingparts. Looseclothes, jewelry
or long hair can be caught
in moving parts.

11. Avoid accidental starting. Be sure switch is off before plugging in. Carrying
tools withyour finger onthe switchor plugging in tools that havetheswitch
on invites accidents.
12. Remove adjusting keys or wrenches before turning the tool on. A wrench
or a key thatisleftattachedtoa rotatingpartofthetool may result
in personal
injury.
13. Do notoverreach. Keepproper footingand balance atalltimes. Properfooting
and balance enables better control of the tool
in unexpected situations.
14. Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
Tool Use and Care
15. Use clamps or other practical way to secure and support the workpiece to
a stable platform. Holdingthe work by handor against your body is unstable
and may lead to loss of control.
16. Do notforce tool. Use the correct toolfor your application. The correct tool
will do the job better and safer at the rate for which it is designed.
17. 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.
18. Disconnectthe plugfromthe 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 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.
21. Check for misalignment or binding of moving parts, breakageof 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.
22. Use only accessories that are recommended by the manufacturer for your
model. Accessories that maybe suitablefor one tool, may becomehazardous
when used on another tool.
S E RVlC E
23. Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of
injury.
24. When servicing a tool, use only identical replacement parts. Follow
instructionsinthe Maintenancesectionof this manual. Use of unauthorized
partsor failure
to follow MaintenanceInstructionsmaycreate a risk of electric
shock or injury.
