GENERAL SAFETY RULES
(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
READ ALL INSTRUCTIONS.
WORK AREA
1. Keep your work area cleanandwell lit. Clutteredbenchesand dark areas invite
accidents.
2. Donotoperatepowertools inexplosiveatmospheres, suchas inthe 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 equippedwithapolarizedplug(onebladeiswider
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 eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoidbody contact with groundedsurfaces such as pipes, radiators, ranges
and refrigerators. There is an increasedrisk of electric shock if your body is
grounded.
6. Don't expose power tools torainor wet conditions. Water entering a power
tool
will increase the risk of electric shock.
7. Donotabuse the cord. Never use the cordtocarry the tools or pullthe plug
from an outlet. Keepcord away from heat,
oil, sharpedges or movingparts.
Replace damaged cords immediately. Damaged cords increase
the risk of
electric shock.
8. Whenoperating a power tool outside, usean outdoor extensioncord 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 youare doingandusecommonsensewhen operating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A momentof inattention whileoperating power tools
may result in serious personal injury.

11. Avoid accidental starting. Be sure switch isoff before plugging in. Carrying
tools with your finger onthe switch
or plugging in tools that havethe switch
on invites accidents.
12. Removeadjusting keys or switchesbefore turning the tool on. A wrench or
a key that is left attachedto a rotating part of the tool may result in personal
injury.
13. Do notoverreach.Keep properfooting andbalanceat alltimes. 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
astable platform. Holdingthe work by handor against your body is unstable
and may lead to
loss of control.
16. Do not force tool. Usethe 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 powersourcebefore 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
maintainedtools,
with sharpcuttingedges are less likelyto bind and are easier
to control.
21. 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 main-
tained tools.
22. Use only accessoriesthat are recommended by the manufacturer for your
model. Accessoriesthat may be suitable for one tool, may become hazardous
when used on another tool.

23. Tool service must be performedonly by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of
injury.
24. When servicing atool, use only identicalreplacement parts. Follow instruc-
tions in the Maintenance section of this manual. Use of unauthorized parts
or failuretofollow Maintenance Instructionsmay createa risk of electric shock
or injury.
