GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep work area clean and well lit. Cluttered benches and dark areas invite ac-
cidents.
Do not operate power tools in explosive atmospheres, such as in the pres-
ence of flammable 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.
Distractions 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 with
a qualified 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 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 with grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
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 immediately. Dam-
aged 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 influence
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 finger 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 personal injury.

Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, nonskid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions. Al-
ways wear ANSI-approved safety goggles and a dust mask/respirator when using
or performing maintenance on this tool.
TOOL USE AND CARE
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 force the
tool and do not use the tool for a purpose for which it is not intended.
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
replaced.
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. Always unplug the tool
from its electrical outlet before performing any inspection, maintenance, or
cleaning procedures.
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 repaired.
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 qualified repair personnel. Service or main-
tenance performed by unqualified personnel could result in a risk of injury.

GROUNDING
WARNING!
A 220 volt plug is not provided with this tool. Have a proper 220 V plug installed
by a qualified electrician. Improperly connecting the grounding wire can result
in the risk of electric shock. Check with a qualified electrician if you are in doubt
as to whether the outlet is properly grounded. Never remove the grounding
prong from the plug. Do not use the tool if the power cord or plug is damaged.
If damaged, have it repaired by a service facility before use.
Extension Cords
Grounded tools require a three wire extension cord. Double Insulated tools can
use either a two or three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a seri-
ous drop in voltage, resulting in loss of power and possible tool damage.
(See Table A.)
The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
When using more than one extension cord to make up the total length, make sure
each cord contains at least the minimum wire size required. (See Table A.)
If you are using one extension cord for more than one tool, add the nameplate am-
peres and use the sum to determine the required minimum cord size.
If you are using an extension cord outdoors, make sure it is marked with the suffix
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified electri-
cian before using it.
Protect your extension cords from sharp objects, excessive heat, and damp or wet
areas.
