• Check for damage to the tool, parts or accessories which may have
occurred duringtransport.
• Take the time to thoroughly read and understand this manual prior
tooperation.
Electrical Safety
The electric motor has been designed for one voltage only. Always check
that the power supply corresponds to the voltage on the rating plate.
Your
DeWALT
tool is double insulated in accordance
with EN62841; therefore no earth wire is required.

WARNING: 115 V units have to be operated via a fail-safe isolating
transformer with an earth screen between the primary and secondary
winding.
If the supply cord is damaged, it must be replaced only by
DeWALT
or an
authorised serviceorganisation.
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the oldplug.
• Connect the brown lead to the live terminal in theplug.
• Connect the blue lead to the neutralterminal.

WARNING: No connection is to be made to the earthterminal.
Follow the fitting instructions supplied with good quality plugs.
Recommended fuse: 13A.
Using an Extension Cable
If an extension cable is required, use an approved 3–core extension cable
suitable for the power input of this tool (see Technical Data).The minimum
conductor size is 1.5 mm
2
; the maximum length is 30 m.
When using a cable reel, always unwind the cablecompletely.

WARNING: We recommend the use of a residual current device with a
residual current rating of 30mA orless.
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
• 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.
