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 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
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 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.

Additional Safety Rules for Mitre Saws


WARNING: Do not connect to the mains power supply into the unit until complete
instructions are read and understood.
DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according
to the instructions. A machine incorrectly assembled can cause serious injury.
OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not
thoroughly familiar with the operation of this machine. Knowledge is safety.
MAKE CERTAIN the blade rotates in the correct direction. The teeth on the blade should point
in the direction of rotation as marked on the saw.
TIGHTEN ALL CLAMP HANDLES, knobs and levers prior to operation. Loose clamps can
cause parts or the workpiece to be thrown at high speeds.
BE SURE all blade and blade clamps are clean, recessed sides of blade clamps are against
blade and arbour screw is tightened securely. Loose or improper blade clamping may result in
damage to the saw and possible personal injury.
DO NOT OPERATE ON ANYTHING OTHER THAN THE DESIGNATED VOLTAGE for the
saw. Overheating, damage to the tool and personal injury may occur.
DO NOT WEDGE ANYTHING AGAINST THE FAN to hold the motor shaft. Damage to tool
and possible personal injury may occur.
NEVER HAVE ANY PART OF YOUR BODY IN LINE WITH THE PATH OF THE SAW
BLADE. Personal injury will occur.
NEVER APPLY BLADE LUBRICANT TO A RUNNING BLADE. Applying lubricant could
cause your hand to move into the blade resulting in serious injury.
DO NOT place either hand in the blade area when the saw is connected to the power source.
Inadvertent blade activation may result in serious injury.
NEVER REACH AROUND OR BEHIND THE SAW BLADE. A blade can cause serious injury.
DO NOT REACH UNDERNEATH THE SAW unless it is unplugged and turned off. Contact
with saw blade may cause personal injury.
SECURE THE MACHINE TO A STABLE SUPPORTING SURFACE. Vibration can possibly
cause the machine to slide, walk, or tip over, causing serious injury.
USE ONLY CROSSCUT SAW BLADES recommended for mitre saws. For best results, do not
use carbide tipped blades with hook angles in excess of 7 degrees. Do not use blades with deep
gullets. These can deflect and contact the guard, and can cause damage to the machine and/
or serious injury.
USE ONLY BLADES OF THE CORRECT SIZE AND TYPE specified for this tool to prevent
damage to the machine and/or serious injury (complying with EN847-1).
INSPECT BLADE FOR CRACKS or other damage prior to operation. A cracked or damaged
blade can come apart and pieces can be thrown at high speeds, causing serious injury.
Replace cracked or damaged blades immediately. Observe the maximum speed marked on
the saw blade.
