General safety rules

Warning! Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term „power tool“ in all of the warnings listed below refers to your mains operated (cored) power tool or battery operated (cordless) power tool. SAVE THESE INSTRUCTIONS.

1 Work area

a Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2 Electrical safety

a Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

3 Personal safety

a Stay alert, watch what you are doing and use common sense when operating a power tool.

Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

b Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c Avoid accidental starting. Ensure the switch is in the off position before plugging in.

Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

d Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust related hazards.

4 Power tool use and care

a Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
b Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

d Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

e Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5 Service

a Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Additional safety rules for cutsaws

Switching on and off

• After switching off, never attempt to stop the saw blade with your fingers.
• Never put the saw down on a table or work bench unless switched off. The saw blade will keep running briefly after the tool has been switched off.

When sawing

• When using saw blades specially designed for cutting wood remove all nails and metal objects from the workpiece before starting work.
• Wherever possible, use clamps and vices to fasten the workpiece securely.
• Do not attempt to saw extremely small workpieces.
• Do not bend too far forward. Make sure that you always stand firmly, particularly on scaffolding and ladders.

• Always hold the saw with both hands.

• For cutting curves and pockets, use an adapted saw blade.

Checking and changing the saw blade

• Only use saw blades conforming to the specifications contained in these operating instructions.
• 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.

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 60745; 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 1三

For 115V units with a power rating exceeding 1500W , 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 machine (see technical data). The minimum conductor size is 1.5mm^2 . The cable has to have a rubber jacket and a grounding conductor.

When using a cable reel, always unwind the cable completely.

Also refer to the table below.

Saw blades

material	recommended saw blade
ferrous metal	fine-toothed
non ferrous metal	coarse-toothed
wood	coarse-toothed
plastic	fine-toothed
masonry carbide-tipped

A wide variety of dedicated saw blades is available as an option.

Always select your saw blade with great care.

Setting the adjustable saw shoe (fig. C)

The saw shoe can be adjusted to limit the depth of cut and prolong the life of your saw blade.

• Push the release lever (6) down.
• Slide the saw shoe (5) into the desired position.
• Push the lever up to secure the shoe in place.

DW311K - Setting the pendulum stroke (fig. D)

The adjustable pendulum stroke guarantees a perfect cutting stroke for different materials. The tool can be used in the following operating modes:

Straight reciprocating motion: for cutting metal and tubes and for finishing wood.

Orbital motion: for fast cutting of wood.

• Turn the selector (3) into the required position aligning the mark (9) with the arrow (10).

Instructions for use

• Always observe the safety instructions and applicable regulations.
• Ensure the material to be sawn is secured in place.
• Apply only a gentle pressure to the tool and do not exert side pressure on the saw blade. If possible, work with the saw shoe pressed against the workpiece. This prevents damage to the blade and stops the tool from jerking and vibrating.
• When sawing in walls or floors be aware of the location of pipework and wiring. Always hold the tool by its handle.
• Avoid overloading.
• Let the blade run freely for a few seconds before starting the cut. Never switch on the tool when the saw blade is jammed in the workpiece or in contact with the material.

Prior to operation:

• Mount the appropriate type of saw blade.

Use narrow saw blades for cutting curves.

Use flexible bimetal saw blades for hard-to-reach positions (e.g. close to walls, etc.).

Switching on and off (fig. A)

• To run the tool, press the variable speed switch (1). The pressure exerted on the variable speed switch determines the tool speed.
• To stop the tool, release the switch. Always switch off the tool when work is finished and before unplugging.

DW311K - Setting the electronic sawing speed (fig. A)

The speed control dial (2) can be used for advance setting of the required range of speed.

• Turn the electronic speed control dial to the required level. The required setting depends on the thickness and kind of material.
• Use high speeds for sawing soft materials such as wood. Use low speeds for sawing metal.

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

Cutting wood

• Clamp the workpiece securely and remove all nails and metal objects.
• Holding the tool with both hands, work with the saw shoe pressed against the workpiece.

Plunge cutting in wood (fig. E)

• Rest the saw shoe on the workpiece in such a position that the blade forms an appropriate angle for the plunge cut.
• Switch the tool on and slowly feed in the blade.
  Make sure that the saw shoe remains in contact with the workpiece at all times.

Pocket cuts

• Measure and mark the required pocket cut.

• Using a narrow saw blade rest the bottom of the saw shoe on the workpiece and make sure that the blade is positioned on the cutting line. If necessary, e.g. in confined spaces, use the outer edge of the saw shoe as your guideline.

• Switch on the tool and feed the blade into the material at full speed, holding the tool firmly against the workpiece.

Dust extraction

• When the tool is used indoor for extended periods of time, use a suitable dust extractor designed in compliance with the applicable Directives regarding dust emission.

Cutting metal

• When cutting thin metal always stabilize the workpiece with wood on both sides. This guarantees clean cuts and prevents damaging of the material.
• For long, straight cuts draw a line on the workpiece.
• Apply a thin film of lubricant along the cutting line, switch on the tool and follow the cutting line.

Cutting plastics

• Always work at reduced speed. Carry out a test cut to check whether the material is sensitive to heat.

Cutting masonry

When sawing asbestos cement hazardous dust may be produced. Follow the statutory guidelines and observe the recommendations issued by the asbestos cement manufacturers.

Sawing up to a projecting edge (fig. F)

• Using a conventional blade installed upside down, cut up to the projected edge.

Consult your dealer for further information on the appropriate accessories.

Maintenance

Your DeWALT power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.

Lubrication

• If the tool will not be used for a long period of time, coat the saw blade with a little oil (e.g. machine oil).

Cleaning

Keep the ventilation slots clear and regularly clean the housing with a soft cloth.
