Safety instructions

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 flammable 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
   Take appropriate measures for the protection of hearing if the sound pressure of 85 dB(A) is exceeded.

10. Secure workpiece
    Use clamps or a vice to hold the workpiece. It is safer and it frees both hands to operate the tool.
11. Do not overreach
    Keep proper footing and balance at all times.
12. Avoid unintentional starting
    Do not carry the plugged-in tool with a finger on the switch. Be sure that the switch is released when plugging in.

    Shut off power and wait for the tool to come to a complete standstill before leaving it unattended. Unplug the tool when not in use, before servicing or changing accessories.
15. Remove adjusting keys and wrenches
    Always check that adjusting keys and wrenches are removed from the tool before operating the tool.
16. Use appropriate tool
    The intended use is described in this instruction manual. Do not force small tools or attachments to do the job of a heavy-duty tool. The tool will do the job better and safer at the rate for which it was intended.
    
    The use of any accessory or attachment or performance of any operation with this tool, other than those recommended in this instruction manual may present a risk of personal injury.
17. Do not abuse cord

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.

Never use a light socket. Never connect the live (L) or neutral (N) wires to the earth pin marked E or .

For 115 V units with a power rating exceeding 1500 W, we recommend to fit a plug to BS4343 standard.

Using an extension cable

If an extension cable is required, use an approved extension cable suitable for the power input of this tool (see technical data). The minimum conductor size is 1.5 mm². When using a cable reel, always unwind the cable completely.
Also refer to the table below.

Assembly and adjustment

Setting the mitre angle (fig. D)
The adjustable shoe (6) allows cutting of LH and RH mitre angles up to 45°. The 0° and 45° positions are preset.

Adjusting the sawdust blower (fig. A)
The sawdust blower conducts an adjustable stream of air to the saw blade to keep the workpiece clear of sawdust during operation.

Mounting the dust extraction adaptor (fig. E)

When appropriate, connect a vacuum cleaner designed in compliance with the applicable directives regarding dust emission. Do not use a vacuum cleaner without proper spark protection when sawing metal.

Mounting and removing the anti-splinter shoe insert (fig. F)
The anti-splinter shoe insert (17) which fits close to the saw blade prevents splintering of the workpiece.

DW321/DW323 - Mounting and removing the plastic anti-scratch shoe cover (fig. G)
The anti-scratch shoe cover (18) prevents damage to the surface of (sensitive) workpieces.

DW321/DW323 - Setting the electronic sawing speed (fig. H)
The sawing speed varies with the pressure exerted on the ON/OFF-switch (1).

After using the tool for an extended period on low speed settings, run it for approx. 3 minutes on maximum no-load speed.

Setting the pendulum stroke (fig. I)
The adjustable pendulum stroke guarantees a perfect cutting speed for different materials.
