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.
1. Keepyour work area cleanandwell lit. Clutteredbenchesand dark areas invite
accidents.
2. Donot operatepowertools in explosive atmospheres,such as in thepresence
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.
4. DoubleInsulatedtoolsare 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, reversethe 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. Don't exposepower tools torainor wet conditions. Water entering a power
tool will increase the risk of electric shock.
7. Donotabuse the cord. Neverusethecord tocarry thetools or pull the plug
from anoutlet. Keepcord away from heat, oil, sharp edgesor movingparts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8. When operating a power tool outside, useanoutdoor extension cordmarked
"W-A" or "W." These cords are rated for outdoor use and reduce the risk
of electric shock.
9. Stay alert, watchwhat youare doingand usecommonsense 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 power tools
may result in serious personal injury.
IO. Dressproperly. Donot wear looseclothing or jewelry. Contain longhair. Keep
your hair, clothing, andglovesawayfrom moving parts. Looseclothes, jewelry
or
long hair can be caught in moving parts.
2

11. Avoid accidental starting. Be sure switchisoff before plugging in. Carrying
tools
with your finger onthe switchor plugging in tools that have the switch
on invites accidents.
12. Removeadjusting 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 inpersonal
injury.
13. Donotoverreach. Keepproperfooting 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.
15. Use clamps or other practical way tosecure 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 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 plugfromthe 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, withsharp cutting edges are less likely to bindandare easier
to control.
21. Check for misalignment or binding of movingparts, breakageof parts, and
any other condition that may affect the tools operation. If damaged, have
the toolservicebeforeusing. Many accidents are caused by poorlymaintained
tools.
22. Use only accessoriesthat are recommended by the manufacturer for your
model. Accessories that may be suitablefor one tool, may become hazardous
when used on another tool.
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 servicingatool, useonly identical replacement parts. Follow instruc-
tions in the Maintenance section of this manual. Use of unauthorized parts
or failure tofollow MaintenanceInstructions maycreate
a riskof electricshock
of injury.
