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. Keepyour work area cleanand well lit. Cluttered benches and dark areas invite
accidents.
2. Donotoperate power tools 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.
5.
6.
7.
8.
Double Insulatedtoolsare equipped with apolarizedplug(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.
Avoid body contact withgrounded surfaces suchas pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
Don't expose power tools torain or wet conditions. Water entering a power
tool
will increase the risk of electric shock.
Do notabuse the cord. Never use the cordtocarry the tools or pullthe plug
from an outlet. Keepcordaway from heat, oil, sharp edges or movingparts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
Whenoperating a powertooloutside, use anoutdoorextension cord marked
"W-A' or "W." These cords are rated for outdoor use and reduce the risk
of electric shock.
PERSONAL SAFETY
9.
10.
Stay alert, watch what you aredoing and usecommonsensewhenoperating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A momentof inattention while operating power tools
may result
in serious personal injury.
Dressproperly. Donot wear loose clothing
or jewelry. Containlonghair. Keep
your hair, clothing, and glovesaway from movingparts. Looseclothes, jewelry
or long hair can be caught in moving parts.
2

11. Avoid accidental starting. Be sure switch isoff before plugging in. Carrying
tools with your finger
on the switchor plugging intools that havethe switch
on invites accidents.
12. Remove adjusting keys or switches beforeturning 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. Keepproperfooting and balanceatalltimes. Proper footing
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 practicalway 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. Do notforce tool. Usethe correcttool 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. Disconnectthe plugfrom the powersource before makingany 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, withsharp cutting edges are less likelyto bindandare easier
to control.
21. Check for misalignmentor binding of moving parts, breakage of parts, and
any other condition that may affect the tools operation..lf damaged, have
the tool serviced before using. Many accidents are caused by poorly main-
tained tools.
22. Use only accessories that are recommendedby the manufacturerfor your
model. Accessories that may be suitablefor one tool, may become hazardous
when used on another tool.
SERVl CE
23. Tool service must be performed only by qualified repair personnel. Service
or maintenance performedby unqualified personnel could result in
a risk of
injury.
24. When servicing a tool, use only identicalreplacementparts. Follow instruc-
tions
in the Maintenance sectionof this manual. Use of unauthorized parts
or failuretofollow MaintenanceInstructions may create
a risk of electricshock
or injury.
