General Safety Rules – For All Tools
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.
• 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. Applicable only to Class II (double insulated) tools.
• 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

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 wrenches 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.
• 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 stable
platform. Holding the work by hand or against your body is unstable and may lead to loss of
control.
• Do not force 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 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.
• 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 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
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 Specific Safety Instructions for Grinders
• Always use proper guard with grinding wheel. A guard protects operator from broken
wheel fragments and wheel contact.
• Accessories must be rated for at least the speed recom mended on the tool warning
label. Wheels and other accessories running over rated speed can fly apart and cause
injury. Accessory ratings must be above listed minimum wheel speed as shown on tool
nameplate.
• 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.
• Always use eye protection. All users and bystanders must wear eye protection that
conforms to ANSI Z87.1.
• Use of accessories not specified in this manual is not recommended and may be
hazardous. Use of power boosters that would cause the tool to be driven at speeds greater
than its rated speed constitutes misuse.
• Do not use circular saw blades or any other toothed blades with this tool. Serious injury
may result.
• When starting the tool with a new or replacement wheel, or a new or replacement wire
brush installed, hold the tool in a well protected area and let it run for one minute. If
the wheel has an undetected crack or flaw, it should burst in less than one minute. If the wire
WALT TOOL,
E
brush has loose wires, they will be detected. Never start the tool with a person in line with
the wheel. This includes the operator.
• Avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and
inspect the wheel for cracks or flaws.
• Direct sparks away from operator, bystanders or flammable materials. Sparks may be
produced while cutting and/or grinding. Sparks may cause burns or start fires.
• Never cut into area that may contain electrical wiring or piping. Serious injury may
result.
• Clean out your tool often, especially after heavy use. Dust and grit containing metal
particles often accumulate on interior surfaces and could create an electric shock hazard.
• Do not operate this tool for long periods of time. Vibration caused by the operating action
of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide
extra cushion, take frequent rest periods, and limit daily time of use.
Causes and Operator Prevention
of Kickback
• Kickback is a sudden reaction to a pinched, bound or misaligned wheel, wire brush or
flap disc causing an uncontrolled cut-off tool to lift up and out of the workpiece toward the
operator.
• When the wheel is pinched or bound tightly by the workpiece, the wheel stalls and the motor
reaction drives the unit rapidly back toward or away from the operator.
• Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and
can be avoided by taking proper precautions as given below:
• Maintain a firm grip with both hands on the unit and position your body and arm to
allow you to resist kickback forces. Kickback forces can be controlled by the operator,
if proper precautions are taken.
• When wheel is binding, or when interrupting a cut for any reason, release the trigger
and hold the unit motionless in the material until the wheel comes to a complete
stop. Never attempt to remove the unit from the work or pull the unit backward while
the wheel is in motion or kickback may occur. Investigate and take corrective actions
to eliminate the cause of wheel binding.
• When restarting a cut-off accessory in the workpiece, check that the wheel is not
engaged into the material. If wheel is binding, it may walk up or kickback from the
workpiece as the tool is restarted.
• Support large panels to minimize the risk of wheel pinching and kickback. Large
panels tend to sag under their own weight. Support must be placed under the panel on
both sides, near the line of cut and near the edge of the panel.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also
use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY
