WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, re, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive atmospheres, such as in the presence
of ammable liquids, gases, or dust. Power tools create sparks which may ignite
the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool. Dis-
tractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
ELECTRICAL SAFETY

Grounded tools must be plugged into an outlet properly installed and grounded
in accordance with all codes and ordinances. Never remove the grounding
prong or modify the plug in any way. Do not use any adapter plugs. Check
REV 03/07
with a qualied electrician if you are in doubt as to whether the outlet is
properly grounded. If the tools should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity away from the user.

Double insulated tools are equipped with a polarized plug (one blade is wider
than the other). This plug will t in a polarized outlet only one way. If the
plug does not t fully in the outlet, reverse the plug. If it still does not t,
contact a qualied 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 with grounded surfaces such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of electric shock if your body is ground-
ed.
Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
Do not abuse the Power Cord. Never use the Power Cord to carry the tools
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,
sharp edges, or moving parts. Replace damaged Power Cords immediate-
ly. Damaged Power Cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord marked “W-
A” or “W”. These extension cords are rated for outdoor use, and reduce the risk
of electric shock.

PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when operat-
ing a power tool. Do not use a power tool while tired or under the inuence
of drugs, alcohol, or medication. A moment of inattention while operating
power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts.
Avoid accidental starting. Be sure the Power Switch is off before plugging in.
Carrying power tools with your nger on the Power Switch, or plugging in power
tools with the Power Switch on, invites accidents.
Remove adjusting keys or wrenches before turning the power tool on. A wrench
or a key that is left attached to a rotating part of the power tool may result in per-
sonal injury.
Do not overreach. Keep proper footing and balance at all times. Proper foot-
ing and balance enables better control of the power tool in unexpected situations.

Use safety equipment. Always wear eye protection. Dust mask, nonskid safe-
ty shoes, hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE

4.
5.
6.
Use clamps (not included) or other practical ways to secure and support the
workpiece to a stable platform. Holding the work by hand or against your body is
unstable and may lead to loss of control.
Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed.
Do not use the power tool if the Power Switch does not turn it on or off. Any tool
that cannot be controlled with the Power Switch is dangerous and must be re-
placed.
Disconnect the Power Cord Plug from 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.
Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly main-
tained tools with a sharp cutting edge are less likely to bind and are easier to
control. Do not use a damaged tool. Tag damaged tools “Do not use” until re-
paired.

Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
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
Tool service must be performed only by qualied repair personnel. Service or
maintenance performed by unqualied personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instruc-
tions in the “Inspection, Maintenance, And Cleaning” section of this man-
ual. Use of unauthorized parts or failure to follow maintenance instructions may
create a risk of electric shock or injury.
