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 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 and clothing
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

3
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
MITRE SAWS
a) Mitre 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 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 100 mm from either side of
the saw blade, to remove wood scraps, or for
any other reason while the blade is spinning.
The proximity of the spinning saw blade to
your hand may not be obvious and you may be
seriously injured.
g) Inspect your workpiece before cutting. If
the workpiece is bowed or warped, clamp
it with the outside bowed face toward the
fence. Always make certain that there
is no gap between the workpiece, fence
and table along the line of the cut. Bent or
warped workpieces can twist or shift and may
cause binding on the spinning saw blade while
cutting. There should be no nails or foreign
objects in the workpiece.
h) Do not use the saw until the table is clear
of all tools, wood scraps, etc., except for
the workpiece. Small debris or loose pieces
of wood or other objects that contact the
revolving blade can be thrown with high speed.
i) Cut only one workpiece at a time. Stacked
multiple workpieces cannot be adequately
clamped or braced and may bind on the blade
or shift during cutting.
j) Ensure the mitre saw is mounted or placed
on a level, firm work surface before use. A
level and firm work surface reduces the risk of
the mitre saw becoming unstable.
k) Plan your work. Every time you change the
bevel or mitre angle setting, make sure the

4
adjustable fence is set correctly to support
the workpiece and will not interfere with
the blade or the guarding system. Without
turning the tool “ON” and with no workpiece
on the table, move the saw blade through a
complete simulated cut to assure there will be
no interference or danger of cutting the fence.
l) Provide adequate support such as table
extensions, saw horses, etc. for a workpiece
that is wider or longer than the table top.
Workpieces longer or wider than the mitre
saw table can tip if not securely supported. If
the cut-off piece or workpiece tips, it can lift
the lower guard or be thrown by the spinning
blade.
m) Do not use another person as a substitute
for a table extension or as additional
support. Unstable support for the workpiece
can cause the blade to bind or the workpiece
to shift during the cutting operation pulling
you and the helper into the spinning blade.
n) The cut-off piece must not be jammed or
pressed by any means against the spinning
saw blade. If confined, i.e. using length stops,
the cut-off piece could get wedged against the
blade and thrown violently.
o) Always use a clamp or a fixture designed
to properly support round material such as
rods or tubing. Rods have a tendency to roll
while being cut, causing the blade to “bite” and
pull the work with your hand into the blade.
p) Let the blade reach full speed before
contacting the workpiece. This will reduce
the risk of the workpiece being thrown.
q) If the workpiece or blade becomes jammed,
turn the mitre saw off. Wait for all moving
parts to stop and disconnect the plug
from the power source and/or remove the
battery pack. Then work to free the jammed
material. Continued sawing with a jammed
workpiece could cause loss of control or
damage to the mitre saw.
r) After finishing the cut, release the switch,
hold the saw head down and wait for the
blade to stop before removing the cut-off
piece. Reaching with your hand near the
coasting blade is dangerous.
s) Hold the handle firmly when making an
incomplete cut or when releasing the switch
before the saw head is completely in the
down position. The braking action of the saw
may cause the saw head to be suddenly pulled
downward, causing a risk of injury.
