When using Power Tools, always observe the safety regulations applicable in your country to reduce the risk of fire, electric shock and personal injury. Read the following safety instructions before attempting to operate this product.

Keep these instructions in a safe place!

General

1 Keep work area clean Cluttered areas and benches can cause accidents.

2 Consider work area environment

Do not expose Power Tools to humidity. Keep work area well lit. Do not use Power Tools in the presence of inflammable liquids or gases.

3 Guard against electric shock

Prevent body contact with earthed surfaces (e.g. pipes, radiators, cookers and refrigerators). For use under extreme conditions (e.g. high humidity, when metal swarf is being produced, etc.) electric safety can be improved by inserting an isolating transformer or a (FI) earth-leakage circuit-breaker.

4 Keep children away

Do not let children come into contact with the tool or extension cord. Supervision is required for those under 16 years of age.

5 Extension cords for outdoor use

When the tool is used outdoors, always use extension cords intended for outdoor use and marked accordingly.

6 Store idle tools

When not in use, Power Tools must be stored in a dry place and locked up securely, out of reach of children.

7 Dress properly

Do not wear loose clothing or jewellery. They can be caught in moving parts. Preferably wear rubber gloves and non-slip footwear when working outdoors. Wear protective hair covering to keep long hair out of the way.

8 Wear safety goggles

Also use a face or dust mask in case the operations produce dust or flying particles.

9 Beware of maximum sound pressure

Additional safety rules for circular saws

Plugging into the mains, switching ON and OFF

• Always ensure that the Power Tool is switched OFF before plugging into the mains.
• Remove the blade changing spanner from the saw blade locking screw before switching ON.
• Do not switch OFF before the saw blade is running freely.

When sawing

• Remove all nails and metal objects from the workpiece before starting work.
• Do not attempt to saw extremely small workpieces.
• After switching OFF, never attempt to stop the saw blade by pressing against the side of the blade.
• Never put the saw down on a table or work bench unless switched OFF.
• Always use the riving knife, except for inserted cuts.

Operational protection devices

• The circular saw must only be used for cutting wood or plastic.
• Ensure that all devices screening the saw blade are in perfect working order.
• Never jam the saw blade guards.
• Free a jammed saw blade guard immediately and do not use the saw if the guard is jammed.
• Do not remove the riving knife.

- The riving knife should be correctly set; the distance between the toothed rim and the riving knife should be 2 mm and the height difference should be 2 mm or less (fig. E).

Checking and changing the saw blade

• Only saw blades conforming to the specifications contained in these operating instructions may be used.
• Saw blades made of high alloy, high speed steel (HSS steel) should not be used. Good results are achieved using carbide-tipped or CrV saw blades.
• Only sharp saw blades in perfect working condition should be used; cracked or bent saw blades should be discarded and replaced at once.
• Ensure that the saw blade is securely fixed and rotates in the correct direction.

Using in a fixed position

• When using a saw bench ensure that the width of the sawing gap is sufficient to take the saw blade being used.
• When cutting narrow workpieces (width less than 80 mm) longitudinally, use a rip fence guide along the longitudinal edge.
• When sawing with the workpiece clamped tight, devices should be used to prevent the workpiece kicking back.
• When sawing circular sections of wood use a device to hold the workpiece steady on both sides of the saw blade to prevent slipping.
• Ensure that pieces of wood sawn off the workpiece cannot be caught up by the teeth of the saw blade and thrown in the air.

Guard against kickback

• Kickback occurs when the saw begins to stall rapidly and is driven back towards the operator. Release the switch immediately if the blade sticks or the saw stalls.
• Keep the saw blades sharp.
• Support large panels near the cutting area.
• Use a fence or straight edge guide when ripping; do not force the tool.
• Do not remove the saw from the work during a cut while the saw blade is rotating. Release the ON/OFF-switch and wait for the saw blade to come to a halt.

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 EN 50144; therefore no earth wire is required.

Mains plug replacement (U.K. & Ireland only)

- Should your mains plug need replacing and you are competent to do this, proceed as instructed below. If you are in doubt, contact an authorized DEWALT repair agent or a qualified electrician.

- Disconnect the plug from the supply.

- Cut off the plug and dispose of it safely; a plug with bared copper conductors is dangerous if engaged in a live socket outlet.

- Only fit 13 Amperes BS1363A approved plugs fitted with the correctly rated fuse (1).

- The cable wire colours, or a letter, will be marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see below). Brown is for Live (L) (2) and Blue is for Neutral (N) (4).

- Before replacing the top cover of the mains plug ensure that the cable restraint (3) is holding the outer sheath of the cable firmly and that the two leads are correctly fixed at the terminal screws.
