General Power Tool Safety Warnings
WARNING! Read all safety warnings and all instructions. Failure to follow the
warnings and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging
the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric
shock.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power tools
may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have
the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench
or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
g) If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection can
reduce dust-related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool
that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the power tool
accidentally.

d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool's
operation. If damaged, have the power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits, etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could
result in a hazardous situation.
5) SERVICE
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Cut-Off Machine Safety Warnings
a) The guard provided with the tool must be securely attached to the power tool and
positioned for maximum safety, so the least amount of wheel is exposed towards
the operator. Position yourself and bystanders away from the plane of the rotating
wheel. The guard helps to protect operator from broken wheel fragments and accidental
contact with wheel.
b) Use only continuous rim diamond cut-off wheels for your power tool. Just because
an accessory can be attached to your power tool, it does not assure safe operation.
c) The rated speed of the accessory must be at least equal to the maximum speed
marked on the power tool. Accessories running faster than their rated speed can break
and fly apart.
d) Wheels must be used only for recommended applications. For example: do not
grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral
grinding, side forces applied to these wheels may cause them to shatter.
e) Always use undamaged wheel flanges that are of correct diameter for your
selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of
wheel breakage.
f) The outside diameter and the thickness of your accessory must be within the
capacity rating of your power tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
g) The arbor size of wheels and flanges must properly fit the spindle of the power tool.
Wheels and flanges with arbor holes that do not match the mounting hardware of the power
tool, will run out of balance, vibrate excessively and may cause loss of control.
h) Do not use damaged wheels. Before each use, inspect the wheels for chips
and cracks. If power tool or wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing the wheel, position yourself and
bystanders away from the plane of the rotating wheel and run the power tool at
maximum no load speed for one minute. Damaged wheels will normally break apart
during this test time.
i) Wear personal protective equipment. Depending on application, use face shield,
safety goggles or safety glasses. As appropriate, wear dust mask, hearing
protectors, gloves and shop apron capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of stopping flying debris generated by
various operations. The dust mask or respirator must be capable of filtrating particles
generated by your operation. Prolonged exposure to high intensity noise may cause hearing
loss.
j) Keep bystanders a safe distance away from work area. Anyone entering the work
area must wear personal protective equipment. Fragments of workpiece or of a broken
wheel may fly away and cause injury beyond immediate area of operation.

k) Hold the power tool by insulated gripping surfaces only, when performing an
operation where the cutting accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool
"live" and could give the operator an electric shock.
l) Position the cord clear of the spinning accessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be pulled into the spinning wheel.
m) Never lay the power tool down until the accessory has come to a complete stop.
The spinning wheel may grab the surface and pull the power tool out of your control.
n) Do not run the power tool while carrying it at your side. Accidental contact with the
spinning accessory could snag your clothing, pulling the accessory into your body.
o) Regularly clean the power tool's air vents. The motor's fan will draw the dust inside the
housing and excessive accumulation of powdered metal may cause electrical hazards.
p) Do not operate the power tool near flammable materials. Sparks could ignite these
materials.
q) The saw is intended to use 4-3/8" (111 mm) diameter continuous rim diamond
blades, 1/16" (1.6 mm) thick with a 7/8" (22.2 mm) center hole diameter. Refer to the
Accessories section for more information.
Further Safety Instructions For Abrasive Cutting-Off
Operations
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging
causes rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to
be forced in the direction opposite of the wheel's rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the
wheel that is entering into the pinch point can dig into the surface of the material causing the
wheel to climb out or kick out. The wheel may either jump toward or away from the operator,
depending on direction of the wheel's movement at the point of pinching. Abrasive wheels may
also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions
and can be avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position your body and arm to allow you
to resist kickback forces. Always use auxiliary handle, if provided, for maximum
control over kickback or torque reaction during start-up. The operator can control
torque reactions or kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory. Accessory may kickback over your
hand.
c) Do not position your body in line with the rotating wheel. Kickback will propel the tool
in direction opposite to the wheel's movement at the point of snagging.
d) Use special care when working corners, sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the
rotating accessory and cause loss of control or kickback.
e) Do not attach a saw chain, woodcarving blade, segmented diamond wheel, or
toothed saw blade. Such blades create frequent kickback and loss of control.
f) Do not jam the wheel or apply excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to
twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.
g) When wheel is binding or when interrupting a cut for any reason, switch off the
power tool and hold the power tool motionless until the wheel comes to a complete
stop. Never attempt to remove the wheel from the cut while the wheel is in motion
otherwise kickback may occur. Investigate and take corrective action to eliminate the
cause of wheel binding.
h) Do not restart the cutting operation in the workpiece. Let the wheel reach full
speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
i) Support panels or any oversized workpiece to minimize the risk of wheel pinching
and kickback. Large workpieces tend to sag under their own weight. Supports must be
placed under the workpiece near the line of cut and near the edge of the workpiece on both
sides of the wheel.
j) Use extra caution when making a "pocket cut" into existing walls or other blind
areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can
cause kickback.
Additional Specifi c Safety Instructions for Masonry Saws
• Never hold piece being cut in your hands or across your leg. Secure the workpiece
to a stable platform. It is important to support the work properly to minimize body
exposure, blade binding, or loss of control.
• Don't unplug if plug or receptacle is wet. Disconnect the fuse or circuit breaker that
supplies power to the tool. Then unplug and examine for presence of water in the receptacle.
• Wait for the saw to come to a complete stop. An unprotected, coasting blade will cause
the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for
the blade to stop after switch is released.
• Do not use to cut wood or metal.
DANGER: Keep hands away from cutting area and blade. Personal injury may result.
WARNING: Always plug extension cord into a GFCI protected outlet.
WARNING: To reduce the risk of electrocution, keep all connections dry and off the
ground. Do not touch plug with wet hands.
WARNING: A Ground Fault Circuit Interrupter (GFCI) is provided on the cord set. Receptacles
are available having built in GFCI protection and may be used for an added measure of safety.
When using an extension cord, always plug into a GFCI protected receptacle or outlet.
WARNING: Test GFCI before each use:
1. Plug GFCI into power outlet. Indicator should turn red.
2. Press test button. Red indicator should disappear.
3. Press reset button for use. Do not use if above test fails.
WARNING: Do not use bonded abrasive wheels with this saw. Personal injury may result.
WARNING: Never use saw with salt water or a conductive fluid.
