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 personal 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 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.
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 adaptor 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. Applicable only to Class I
(grounded) tools. The DW274W and DW286G units are grounded.
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
the need for the three wire grounded power cord and grounded power supply system.
Applicable only to Class II (double insulated) tools. The DW251, DW252,
DW255,DW257, DW260, DW262, DW263, DW265, DW266, DW267, DW268, DW269,
DW272, DW274, DW276, DW281, DW282 and DW284 units are double insulated.
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.
Don't expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tools or pull the 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.
When operating a power tool outside, use an outdoor extension cord marked
"W-A" or "W." These cords are rated for outdoor use and reduce the risk of electric
shock. When using an extension cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. The following table shows the correct size
to use depending on cord length and nameplate ampere rating. If in doubt, use the next
heavier gage. The smaller the gage number, the heavier the cord.

WALT PERSONAL SAFETY
Stay alert, watch what you are doing and use common sense when operating 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,
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from moving parts. Loose clothing, jewelry, or long
hair can be caught in moving parts. Air vents often cover moving parts and should also
be avoided.
Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools that have the switch on invites accidents.
Remove adjusting keys or switches before turning the tool on. A wrench or key
that is left attached to a rotating part of the 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 tool in unexpected situations.
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
Use clamps or other practical way to secure and support the workpiece to a sta-
ble platform. Holding the work by hand or against your body is unstable and may lead
to a loss of control.
Do not force tool. Use the correct tool for your application. The correct tool will do the
job better and safer and the rate for which it is designed.
Do not use tool if switch does not turn it on or off. Any tool that cannot be con-
trolled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source before making any adjustments,
changing accessories, or storing the tool. Such preventative 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 maintained
tools, with sharp cutting edges are less likely to bind and are easier to control.
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 serv-
iced 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
maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instructions in
the Maintenance section of this manual. Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of electric shock or injury.
Additional Safety Rules
Hold tool by insulated gripping surfaces when performing an operation 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.
Keep handles dry, clean, free from oil and grease. It is recommended to use rubber
gloves. This will enable better control
KEEP TOOL DRY FROM SWEAT DURING USE. Reduce risk of electric shock by pre-
venting perspiration or other liquids from entering the tool during use in hot/humid con-
ditions. Use wristbands, gloves, drying towels or cloths as necessary.
