DeWalt DWS771 - Electrical Safety

9
ENGLISH
• 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.

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 unprotected saw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 increases the risk of breathingproblems:
• No dust extractor connected when sawing wood
• Insufficient dust extraction caused by uncleaned exhaust filters
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
EN60745; 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 by a specially prepared
cord available through the
DeWALT
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.
