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. Keep your work area clean andwell lit. Clutteredbenchesand dark areas invite
accidents.
2. Do notoperatepowertools inexplosiveatmospheres, suchas 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. DoubleInsulated tools are equippedwitha polarized plug(one bladeiswider
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
H eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoid 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 to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
7. Donotabusethe cord. Never usethe cordto carry the tools or pullthe plug
from anoutlet. Keep cordaway from heat, oil, sharp edgesor moving parts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8. Whenoperating a power tooloutside, use anoutdoor extension cordmarked
"W-A' or "W." These cords are rated for outdoor use and reduce the risk
of electric shock.
9. Stay alert, watch what youaredoing andusecommonsense whenoperating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A moment of inattentionwhile operating power tools
may result in serious personal injury.
IO. Dress properly. Do not wear looseclothing orjewelry. Contain longhair. Keep
your hair, clothing, andgloves away from movingparts. 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 onthe switch or plugging intools 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. Keepproperfooting and balanceat 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 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. Usethe 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. Disconnect the plugfrom the 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
maintainedtools,
with sharp cutting edges are less likelytobind 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 service before using. Many accidents are caused by poorly maintained
tools.
22. Use only accessories that 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 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 identicalreplacement parts. Follow instruc-
tions
in the Maintenance section of this manual. Use of unauthorized parts
or failure tofollow Maintenance Instructions may create a riskof electric shock
of injury.

Refer to the table at right to select the
proper speed for the workpiece to be cut.
However, the appropriate speed may differ
with the type or thickness of the work-
