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 residual current
device (RCD) protected supply. Use of an RCD 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 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 jewellery. 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.
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) 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.
Safety Instructions for Table Saws
1) Guarding Related Warnings
a ) Keep guards in place. Guards must be in working order and be properly mounted. A
guard that is loose, damaged, or is not functioning correctly must be repaired or replaced.
b ) Always use saw blade guard, riving knife and anti-kickback pawls for every
through-cutting operation. For through-cutting operations where the saw blade cuts
completely through the thickness of the workpiece, the guard and other safety devices help
reduce the risk of injury.
c ) Immediately reattach the guarding system after completing an operation (such
as rabbeting cuts) which requires removal of the guard, riving knife and/or anti-
kickback device. The guard, riving knife, and anti-kickback device help to reduce the risk
of injury.
d ) Make sure the saw blade is not contacting the guard, riving knife or the workpiece
before the switch is turned on. Inadvertent contact of these items with the saw blade
could cause a hazardous condition.
e ) Adjust the riving knife as described in this instruction manual. Incorrect spacing,
positioning and alignment can make the riving knife ineffective in reducing the likelihood
of kickback.
f ) For the riving knife and anti-kickback pawls to work, they must be engaged in the
workpiece. The riving knife and anti-kickback pawls are ineffective when cutting workpieces
that are too short to be engaged with the riving knife and anti-kickback pawls. Under these
conditions a kickback cannot be prevented by the riving knife and anti-kickback pawls.
g ) Use the appropriate saw blade for the riving knife. For the riving knife to function
properly, the saw blade diameter must match the appropriate riving knife and the body of
the saw blade must be thinner than the thickness of the riving knife and the cutting width of
the saw blade must be wider than the thickness of the riving knife.
2) Cutting Procedures Warnings
a ) DANGER: Never place your fingers or hands in the vicinity or in line with the
saw blade. A moment of inattention or a slip could direct your hand towards the
saw blade and result in serious personal injury.
b ) Feed the workpiece into the saw blade or cutter only against the direction of
rotation. Feeding the workpiece in the same direction that the saw blade is rotating above
the table may result in the workpiece, and your hand, being pulled into the saw blade.
c ) Never use the miter gauge to feed the workpiece when ripping and do not use the
rip fence as a length stop when cross cutting with the miter gauge. Guiding the
workpiece with the rip fence and the miter gauge at the same time increases the likelihood of
saw blade binding and kickback.
d ) When ripping, always apply the workpiece feeding force between the fence and the
saw blade. Use a push stick when the distance between the fence and the saw blade
is less than 5.9" (150 mm), and use a push block when this distance is less than 2"
(50 mm). "Work helping" devices will keep your hand at a safe distance from the saw blade.
e ) Use only the push stick provided by the manufacturer or constructed in accordance
with the instructions. This push stick provides sufficient distance of the hand from the
saw blade.
f ) Never use a damaged or cut push stick. A damaged push stick may break causing your
hand to slip into the saw blade.
g ) Do not perform any operation "freehand". Always use either the rip fence or the
miter gauge to position and guide the workpiece. "Freehand" means using your
hands to support or guide the workpiece, in lieu of a rip fence or miter gauge.
Freehand sawing leads to misalignment, binding and kickback.
h ) Never reach around or over a rotating saw blade. Reaching for a workpiece may lead to
accidental contact with the moving saw blade.
i ) Provide auxiliary workpiece support to the rear and/or sides of the saw table
for long and/or wide workpieces to keep them level. A long and/or wide workpiece
has a tendency to pivot on the table's edge, causing loss of control, saw blade binding
and kickback.
j ) Feed workpiece at an even pace. Do not bend or twist the workpiece. If jamming
occurs, turn the tool off immediately, unplug the tool then clear the jam. Jamming
the saw blade by the workpiece can cause kickback or stall the motor.
