ENGLISH
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.
• CLEAN THE BLADE AND BLADE CLAMPS prior to operation. Cleaning
the blade and blade clamps allows you to check for any damage to the
blade or blade clamps. A cracked or damaged blade or blade clamp
can come apart and pieces can be thrown at high speeds, causing
seriousinjury.
• THE MAXIMUM SPEED OF THE SAW BLADE shall always be greater
than or at least equal to the speed marked on the rating plate of the tool.
• THE SAW BLADE DIAMETER must be in accordance with the markings
on rating plate of the tool.
• DO NOT USE WARPED BLADES. Check to see if the blade runs true and
is free from vibration. A vibrating blade can cause damage to the machine
and/or seriousinjury.
• DO NOT use lubricants or cleaners (particularly spray or aerosol) in the
vicinity of the plastic guard. The polycarbonate material used in the guard
is subject to attack by certainchemicals.
• KEEP GUARD IN PLACE and in workingorder.
• ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN
DAMAGED. Small chip accumulation under the saw may interfere with
the saw blade or may cause instability of workpiece whencutting.
• USE ONLY BLADE CLAMPS SPECIFIED FOR THIS TOOL to prevent
damage to the machine and/or seriousinjury.
• MAKE SURE to use the correct saw blade for the material to becut.
• CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor
air slots can cause the machine to overheat, damaging the machine and
possibly causing a short which could cause seriousinjury.
• NEVER LOCK THE SWITCH IN THE “ON” POSITION. Severe personal
injury mayresult.
• NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or
if the cutting tool is unintentionallycontacted.

WARNING: Cutting plastics, sap coated wood, and other materials
may cause melted material to accumulate on the blade tips and the
body of the saw blade, increasing the risk of blade overheating and
binding whilecutting.

WARNING: Always wear proper personal hearing protection.
Under some conditions and duration of use, noise from this product
may contribute to hearing loss. Be aware of the following factors
influencing exposure to noise:
• Use saw blades designed to reduce the emitted noise,
• Use only well sharpened saw blades, and
• Use specifically designed noise-reduction sawblades.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT
safety glasses. Also use face or dust mask if cutting operation isdusty.

WARNING: Use of this tool can generate and/or disperse dust, which
may cause serious and permanent respiratory or otherinjury.

WARNING: 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:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treatedlumber.
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.
• Avoid prolonged contact with dust from power sanding, 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.

WARNING: Use of this tool can generate and/or disperse dust, which
may cause serious and permanent respiratory or other injury. Always
use approved respiratory protection appropriate for the dustexposure.
