GENERAL POWER TOOL SAFETY WARNINGS
Read all safety warnings and 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 flam-
mable 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 per-
sonal 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 connect-
ing to power source and/or battery pack, picking up or carrying the tool. Carrying power
tools with your finger on the switch or energising 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, jewellery 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 pre-
ventive 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 dan-
gerous 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 replace-
ment parts. This will ensure that the safety of the power tool is maintained.
ADDITIONAL SPECIFIC SAFETY RULES
SAFETY WARNINGS COMMON FOR GRINDING, SANDING, WIRE BRUSHING, POLISHING OR
ABRASIVE CUTTING-OFF OPERATIONS:
a) This power tool is intended to function as sander or polisher. Read all safety warnings,
instructions, illustrations and specifications provided with this power tool. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious injury.
b) Operations such as grinding, wire brushing or cutting-off are not recommended to be
performed with this power tool. Operations for which the power tool was not designed may
create a hazard and cause personal injury.
c) Do not use accessories which are not specifically designed and recommended by the
tool manufacturer. Just because the accessory can be attached to your power tool, it does not
assure safe operation.
d) 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.
e) 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 con-
trolled.
f) The arbor size of wheels, flanges, backing pads or any other accessory must properly fit
the spindle of the power tool. Accessories 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.
g) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose
or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undam-
aged accessory. After inspecting and installing an accessory, position yourself and bystanders
away from the plane of the rotating accessory and run the power tool at maximum no-load speed
for one minute. Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Depending on application, use face shield, safety gog-
gles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop
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.
i) 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 accessory may fly
away and cause injury beyond immediate area of operation.
j) Hold 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 contact-
ing a "live" wire may make exposed metal parts of the power tool "live" and shock the operator.
k) 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 accessory.
l) Never lay the power tool down until the accessory has come to a complete stop. The spin-
ning accessory may grab the surface and pull the power tool out of your control.
m) 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.
n) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the hous-
ing and excessive accumulation of powdered metal may cause electrical hazards.
o) Do not operate the power tool near flammable materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may
result in electrocution or shock.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other
accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes
the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the
point of the binding.
For example, if a backing pad is snagged or pinched by the workpiece, the edge of the pad 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.
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 the area where power tool will move if kickback occurs. 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 or toothed saw blade. Such blades create
frequent kickback and loss of control.
SAFETY WARNINGS SPECIFIC FOR SANDING OPERATIONS:
a) Do not use excessively oversized sanding disc paper. Follow manufacturer’s recommenda-
tions when selecting sanding paper. Larger sanding paper extending beyond the sanding pad
presents a laceration hazard and may cause snagging, tearing of the disc or kickback.
SAFETY WARNINGS SPECIFIC FOR POLISHING OPERATIONS:
a) Do not allow any loose portion of the polishing bonnet or its attachment strings to spin
freely. Tuck away or trim any loose attachment strings. Loose and spinning attachment
strings can entangle your fingers or snag on the workpiece.
EXTENSION CORD
An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety.
The smaller the gauge number of the wire, the greater the capacity of the cable, that is 16 gauge
has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in
loss of power and overheating. When using more than one extension to make up the total length, be
sure each individual extension contains at least the minimum wire size. The following table shows
the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the
next heavier gauge. The smaller the gauge number, the heavier the cord.

Always use eye protection. All users and bystanders must wear eye protection that
conforms to ANSI Z87.1.
Always wear proper personal hearing protection that conforms to ANSI S12.6
(S3.19) during use. Under some conditions and duration of use, noise from this product may
contribute to hearing loss.
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 EQUIPMENT:
• ANSIZ87.1eyeprotection(CAN/CSAZ94.3),
• ANSIS12.6(S3.19)hearingprotection,
• NIOSH/OSHA/MSHArespiratoryprotection.
Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• leadfromlead-basedpaints,
• crystallinesilicafrombricksandcementandothermasonryproducts,and
• arsenicandchromiumfromchemically-treatedlumber(CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with approved
safety equipment, such as those dust masks that are specially designed to filter out microscopic
particles.
• Avoidprolongedcontactwithdustfrompowersanding, sawing,grinding,drilling, and
other construction activities. Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption
of harmful chemicals.
Use of this tool can generate and/or disburse dust, which may cause serious and perma-
nentrespiratoryorotherinjury.AlwaysuseNIOSH/OSHAapprovedrespiratoryprotectionappropriatefor

ADDITIONAL SAFETY RULES FOR PAINT REMOVAL
1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the con-
taminated dust. The greatest danger of lead poisoning is to children and pregnant women.
2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis, we
recommend the following precautions when sanding any paint:
PERSONAL SAFETY
1. No children or pregnant women should enter the work area where the paint sanding is being
done until all clean up is completed.
2. A dust mask or respirator should be worn by all persons entering the work area. The filter should
be replaced daily or whenever the wearer has difficulty breathing. See your local hardware store
fortheproperNIOSHapproveddustmask.
3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingesting
contaminated paint particles. Workers should wash and clean up BEFORE eating, drinking or
smoking. Articles of food, drink, or smoking should not be left in the work area where dust would
settle on them.
