DeWalt DW712 Original Instructions Manual page 28

EnGLIsh
• 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.
• 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.
• 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.

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.
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 D WALT tool is double insulated in accordance with EN62841; therefore no
e
earth wire is required.

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.
