ENGLISH
• 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.
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.
Chargers
DeWALT chargers require no adjustment and are designed to be as easy as
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 DeWALT charger is double insulated in accordance with
IEC60335; therefore no earth wire isrequired.
If the supply cord is damaged, it must be replaced only by DeWALT or an
authorised serviceorganisation.
Using an Extension Cable
An extension cord should not be used unless absolutely necessary. Use an
approved extension cable suitable for the power input of your charger (see
Technical Data). The minimum conductor size is 1mm
2
; the maximum
length is30m.
When using a cable reel, always unwind the cablecompletely.
Important Safety Instructions for All Battery
Chargers
SAVE THESE INSTRUCTIONS: This manual contains important safety
and operating instructions for compatible battery chargers (refer to
TechnicalData).
• Before using charger, read all instructions and cautionary markings on
charger, battery pack, and product using batterypack.

WARNING: Shock hazard. Do not allow any liquid to get inside
charger. Electric shock mayresult.

WARNING: We recommend the use of a residual current device with a
residual current rating of 30mA orless.

CAUTION: Burn hazard. To reduce the risk of injury, charge only
DeWALT rechargeable batteries. Other types of batteries may burst
causing personal injury anddamage.
