Before returning the BLACK & DECKER JS4000 for any reason please call 1-800-544-6986.

Before you call, have the catalog No. and date code available.

Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.

Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

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.

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.

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.

If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

Always wear eye protection.

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.

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.

Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

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.

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

Use the power tool, accessories and tool bits etc., in accordance with these instructions, 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.

Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

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.

Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

Use clamps or another practical way to secure and support the work piece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

Keep hands away from cutting area. Never reach underneath the material for any reason. Hold front of saw by grasping the contoured gripping area. Do not insert fingers or thumb into the vicinity of the reciprocating blade and blade clamp. Do not stabilize the saw by gripping the shoe.

Keep blades sharp. Dull blades may cause the saw to swerve or stall under pressure.

When cutting pipe or conduit ensure that they are free from water, electrical wiring, etc.

Allow the motor to come to a complete stop before withdrawing the blade from the kerf (the slot created by cutting). A moving blade may impact the workpiece causing a broken blade, workpiece damage or loss of control and possible personal injury.

Never hold work in your hand, lap or against parts of your body when sawing. The saw may slip and the blade could contact the body causing injury.

Keep handles dry, clean, free from oil and grease. This will enable better control of the tool.

Clean out your tool often, especially after heavy use. Dust and grit containing metal particles often accumulate on interior surfaces and could create an electric shock hazard.

Do not operate this tool for long periods of time. Vibration caused by the operating action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide extra cushion, take frequent rest periods, and limit daily time of use.

Make sure the extension cord is in good condition before using. Always use the proper size extension cords with the tool – that is, proper wire size for various lengths of cord and heavy enough to carry the current the tool will draw. Use of an undersized cord will cause a drop in line voltage resulting in loss of power and overheating. For proper size cords see chart below.

Minimum Gage for Cord Sets

Be sure your power supply agrees with nameplate marking. 120 Volts AC only means your tool will operate on standard 60 Hz household power. Do not operate AC tools on DC. A rating of 120 volts AC/DC means that you tool will operate on standard 60 Hz AC or DC power. This information is printed on the nameplate. Lower voltage will cause loss of power and can result in over-heating.

Hold the saw blade (5) as shown, with teeth facing forward.

Push the lever (3) downwards.

Insert the shank of the saw blade into the blade holder (10) as far as it will go.

Release the lever.

Adjust the blade support roller as described below.

Turn the locking knob (7) in direction A.

Slide the blade support roller against the rear of the blade. The blade must locate in the central recess of the roller.

Turn the locking knob (7) in direction B to lock the shoe plate in place.

Align the dust extraction adaptor (9) with the saw shoe as shown.

Insert the ribs (12) into the slots (13).

Rotate the adaptor until it locks into position. Make sure that the ribs (14) are correctly seated.

Connect the vacuum cleaner hose (11)(not supplied) to the adaptor.

Note: Dust extraction is not possible when making bevel cuts.

The shoe plate can be set to a left or right bevel angle of up to 45°.

Turn the locking knob (7) in direction A to release the shoe plate (6).

Pull the shoe plate (6) backwards and set it to the required angle. You can use the scale or a protractor to check the angle.

Turn the locking knob (7) in direction B to lock the shoe plate in place.

Turn the locking knob (7) in direction A to release the shoe plate (6).

Pull the shoe plate backwards and set it to an angle of approximately 0.

Push the shoe plate forward.

Turn the locking knob (7) in direction B to lock the shoe plate in place. Make sure that the shoe plate is supported by the guide ribs.

To switch the tool on, press the variable speed switch (1). The tool speed depends on how far you depress the switch.

For continuous operation, press the lock-on button (2) and release the variable speed switch. This option is available only at full speed.

To switch the tool off, release the variable speed switch. To switch the tool off, when in continuous operation, press the variable speed switch once more and release it.

Use a pencil to mark the cutting line.

Position the jigsaw over the line (15).

Viewing from directly above the jigsaw the line of cut can be easily followed. Should this view be restricted for any reason, the indent (16) can be used as an alternate cutting guide.

Use a high speed for wood, a medium speed for aluminum and PVC and a low speed for metals other then aluminum.

As the saw blade cuts on the upward stroke, splintering may occur on the surface closest to the shoe plate.

Use a fine-tooth saw blade.

Saw from the back surface of the workpiece.

To minimize splintering, clamp a piece of scrap wood or hardboard to both sides of the workpiece and saw through this sandwich.

Be aware that sawing metal takes much more time than sawing wood.

Use a saw blade suitable for sawing metal.

When cutting thin metal, clamp a piece of scrap wood to the back surface of the workpiece and cut through this sandwich.

Spread a film of oil along the intended line of cut.

Do not use vacuum adapter when cutting metal. Metal filings will be hot and may cause a fire.

Insert rip fence into slot on the right side of saw shoe as shown with cross bar facing down.

Place screw (19) into hole in bottom of shoe.

Align clamp bar (20) over screw with lipped edge facing down and pointing towards the rear of the saw.

Using a phillips screwdriver, run the screw into the threaded hole in the bar clamp.

Adjust to width of cut and tighten screw.

Insert rip fence into slot on the right side of saw shoe with cross bar facing up.

Adjust rip fence so that distance from blade to hole in cross bar is the desired radius and tighten screw.

Place saw so that center of hole in cross bar is over center of circle to be cut (make pocket cut, drill hole for blade or cut inward from edge of material to get blade into position).

When saw is properly positioned, drive a small nail through hole in cross bar into exact center of circle to be cut. Using rip fence as a pivot arm, begin cutting circle.

Possible causes include: Cord not plugged in, Circuit fuse is blown, Circuit breaker is tripped, or Cord or switch is damaged.

Have cord or switch replaced at a Black & Decker Service Center or Authorized Servicer.

Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

Repairs, maintenance and adjustment should be performed by authorized service centers or other qualified service personnel, always using identical replacement parts.
