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 cleanandwell lit. Cluttered benches and dark areas invite
accidents.
2. Donotoperate powertools inexplosiveatmospheres, suchas 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.
ELECTRICAL SAFETY
4. Double Insulatedtools are equipped witha polarized plug(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 H eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoid body contactwith 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. Do notabuse the cord. Never use the cordtocarry the tools or pullthe plug
from an outlet. Keep cord away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged cords increase the risk
of
electric shock.
8. Whenoperating a powertooloutside, use an outdoor 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, watch whatyou are doing 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 powertools
may result
in serious personal injury.
IO. Dressproperly. Do notwear loose clothing orjewelry. Contain long hair. Keep
your hair, clothing, and glovesaway from movingparts. Looseclothes, jewelry
or long hair can be caught in moving parts.
L

11. Avoid accidental starting. Be sure switchis off before plugging in. Carrying
tools
with your finger onthe switch or 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 attachedto a rotating part of the tool may result in personal
injury.
13. Do notoverreach.Keepproperfooting and balanceat alltimes. 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 practical way to secure and support the workpiece to
a stable platform. Holding the work by handor against your body is unstable
and may lead to
loss of control.
16.
Do notforce tool. Usethe correct tool for your application. The correcttool
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 power source 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
maintained tools, with sharp cuttingedges 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 tools operation.
If damaged, have
the toolservice before using. Many accidents are caused by poorly maintained
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.
SERVICE
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 to follow Maintenance Instructions may create a risk of electric shock
of injury.

Specific Safety Rules
1. Holdtools by insulated gripping surfaceswhen performing anoperation where
the cutting tool may contact hidden wiring or its own cord. Contact
with a
"live" wire
will make exposed metal parts of the tool "live" and shock the
operator.
2. Wear ear protectors when using the tool for extended periods. Prolonged
exposure to high intensity noise can cause hearing
loss.
3. Wear a hard hat (safety helmet), safety glasses and/or face shield. It is also
highly recommended that you wear a dust mask, ear protectors and thickly
padded gloves.
4. Undernormaloperation, the tool isdesignedtoproduce vibration. The screws
can come loose easily, causing a breakdownor accident. Check tightness of
screws carefully before operation.
5. Always be sure you have a firm footing.
Be sure no one is below when using the tool
in high locations.
6. Hold the tool firmly with both hands. Always use the side grip.
7. Keep hands away from rotating parts.
8. Do not leave the tool running. Operate the tool only when hand-held.

ton from the side with
&QQ symbol to use "rotation only" action.
*Drilling inwood
When drilling inwood, best results are obtainedwith wood drillsequippedwith
a guide
screw. The guide screw makesdrilling easier by pulling the bit intothe workpiece.
To prevent the bit from slipping when starting a hole, make an indentation with a
centerpunch and hammer at the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use
a cutting lubricant when drilling metals. The exceptions are iron and brass which
should bedrilled drv.
*Drilling in metal
CAUTION:
*Pressing excessivelyon the
tool will not speed up the drilling. Infact, this excessive pres-
sure will only serve to damage the tip of your bit, decrease the tool performance and
shorten the service life of the tool.
*There is
a tremendous twisting force exerted on the tool/bit at the time of hole break-
through. Hold the tool firmly and exert care when the bit begins to break through the
workpiece.
*A stuck bit can be removed simply by setting the reversing switch to reverse rotation in
order
to back out. However, the tool may back out abruptly if you do not hold it firmly.
