GENERAL POWER TOOL SAFETY WARNINGS


WARNING: 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.
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 a 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.
h ) Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe
injury within a fraction of a second.
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 remove the battery pack,
if detachable, 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 and accessories. 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.
h ) Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and control of the
tool in unexpected situations.
5) Battery Tool Use and Care
a ) Recharge only with the charger specified by the manufacturer. A charger that is
suitable for one type of battery pack may create a risk of fire when used with another
battery pack.
b ) Use power tools only with specifically designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
c ) When battery pack is not in use, keep it away from other metal objects, like paper
clips, coins, keys, nails, screws or other small metal objects, that can make a
connection from one terminal to another. Shorting the battery terminals together
may cause burns or a fire.
d ) Under abusive conditions, liquid may be ejected from the battery; avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the battery may cause irritation
or burns.
e ) Do not use a battery pack or tool that is damaged or modified. Damaged or
modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk
of injury.
f ) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to
fire or temperature above 265 °F (130 °C) may cause explosion.
g ) Follow all charging instructions and do not charge the battery pack or tool
outside the temperature range specified in the instructions. Charging improperly
or at temperatures outside the specified range may damage the battery and increase the
risk of fire.
6) 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.
b ) Never service damaged battery packs. Service of battery packs should only be
performed by the manufacturer or authorized service providers.
Safety Instructions for Miter Saws
a ) Miter saws are intended to cut wood or wood‑like products, they cannot be used
with abrasive cut‑off wheels for cutting ferrous material such as bars, rods, studs,
etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from
abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
b ) Use clamps to support the workpiece whenever possible. If supporting the
workpiece by hand, you must always keep your hand at least 4" (100 mm) from
either side of the saw blade. Do not use this saw to cut pieces that are too small to
be securely clamped or held by hand. If your hand is placed too close to the saw blade,
there is an increased risk of injury from blade contact.
c ) The workpiece must be stationary and clamped or held against both the fence
and the table. Do not feed the workpiece into the blade or cut "freehand" in any
way. Unrestrained or moving workpieces could be thrown at high speeds, causing injury.
d ) Push the saw through the workpiece. Do not pull the saw through the workpiece.
To make a cut, raise the saw head and pull it out over the workpiece without
cutting, start the motor, press the saw head down and push the saw through the
workpiece. Cutting on the pull stroke is likely to cause the saw blade to climb on top of
the workpiece and violently throw the blade assembly towards the operator.
e ) Never cross your hand over the intended line of cutting either in front or behind
the saw blade. Supporting the workpiece "cross handed" i.e. holding the workpiece to the
right of the saw blade with your left hand or vice versa is very dangerous.
f ) Do not reach behind the fence with either hand closer than 4" (100 mm) from
either side of the saw blade, to remove wood scraps, or for any other reason while
