GENERAL SAFETY RULES
(For All Tools)
WARNING! Read and understand all instructions. Failure
to
follow all instructionslistedbelow, may result in electric
shock, fire
and/or serious personal injury.
SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS.
WORK AREA
1. Keep your work area clean andwell lit. Cluttered benches and dark areas invite
accidents.
2. Donot operate power tools 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 loose control.
E LECT R I CA L 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.rAvoid body contact with grounded surfaces such as pipes, radiators, ranges
and refrigerators.There
is an increased risk of electric shock if your body is
grounded.
6. Don't expose power tools torain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
7. Donot abuse the cord. Never use the cord tocarry the tools or pull the plug
from an outlet. Keepcordaway from heat,
oil, sharp edges or movingparts.
Replace damaged cords immediately. Damaged cords increase the
risk of
electric shock.
8. Whenoperating a power tool outside, useanoutdoor 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 you are doing andusecommonsensewhenoperating
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.
IO. Dressproperly. Donotwear loose clothingorjewelry. Containlonghair. Keep
your hair, clothing, andgloves away from moving parts. Loose clothes, jewelry
or long hair can be caught in moving parts.

11. Avoid accidental starting. Be sure switch is off before plugging in. Carrying
tools
with your finger ontheswitchor plugging in tools that have the switch
on invites accidents.
12. Remove adjusting keys or switches 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.
13. Donotoverreach. Keep proper footing and balanceatalltimes. 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 hand or against your body is unstable
and may lead to
loss of control.
16. Donotforce 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 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. Disconnect the plugfrom the power source beforemakingany 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
maintainedtools,
with sharp cutting edges are less likely to bindand are easier
to control.
21. 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.
22. 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.
S ERVl CE
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 instruc-
tions in the Maintenance section of this manual. Use
of unauthorized parts
or failure tofollow MaintenanceInstructionsmay create a risk of electric shock
or injury.

apart and cause injury.
3. Holdtool by insulated gripping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its own cord. Contact
with a
"live" wire
