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 CUT FERROUS METALS OR MASONRY. Either of these can cause
the carbide tips to fly off the blade at high speeds causing serious injury.
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 has been turned
off and the battery packs have been remvoved. 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. Always
use approved respiratory protection appropriate for the dust exposure.

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.
Residual Risks
The following risks are inherent to the use of saws:
Injuries caused by touching the rotating parts.
In spite of the application of the relevant safety regulations and the
implementation of safety devices, certain residual risks cannot be avoided.
These are:
Impairment of hearing.
Risk of accidents caused by the uncovered parts of the rotating saw blade.
Risk of injury when changing the blade.
Risk of squeezing fingers when opening the guards.
Health hazards caused by breathing dust developed when sawing wood,
especially oak, beech and MDF.
The following factors increase the risk of breathing problems:
No dust extractor connected when sawing wood.
Insufficient dust extraction caused by uncleaned exhaust filters.
SAVE THESE INSTRUCTIONS
Chargers
D
WALT chargers require no adjustment and are designed to be as easy as
e
possible to operate.
Electrical Safety
The electric motor has been designed for one voltage only. Always check
that the battery pack voltage corresponds to the voltage on the rating
plate. Also make sure that the voltage of your charger corresponds to that
of your mains.
Your D
WALT charger is double insulated in accordance with
e
EN60335; therefore no earth wire is required.
