Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.

• 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.

• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• 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.

• 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 expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

• 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.

Personal safety

• 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.

• 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.

• 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.

• 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.

• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

• 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.

• Hold tool 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.

• Never leave the trigger locked “ON”. Before plugging the tool in, check that the trigger lock is “OFF”. Accidental start-ups could cause injury.

• Be aware of the location and setting of the switch “Lock-ON” button. If the switch is locked “ON” during use, be ready for emergency situations to switch it “OFF”, by first pulling the trigger then immediately releasing it without pressing the “Lock-ON” button.

• Keep hands away from cutting area. Do not reach under the material being cut. The proximity of the blade to your hand is hidden from your sight.

• Keep hands from between the gear housing and saw blade holder. The reciprocating blade holder can pinch your fingers.

• Do not use dull or damaged blades. A bent blade can break easily or cause kickback.

• Before starting to cut, turn tool “ON” and allow the blade to come to full speed. The tool can chatter or vibrate if the blade speed is too slow at the beginning of the cut and possibly kickback.

• Secure material before cutting. Never hold it in your hand or across your legs. Small or thin material may flex or vibrate with the blade, causing loss of control.

• Make certain all adjusting screws and the blade holder are tight before making a cut. Loose adjusting screws and holders can cause the tool or blade to slip and loss of control may result.

• When removing the blade from the tool, avoid contact with skin and use proper protective gloves when grasping the blade or accessory. Accessories may be hot after prolonged use.

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.

This jigsaw is equipped with the Bosch “One Touch” tool-less blade changing system.

Installation:

1. Insert the saw blade (teeth in cutting direction) until it latches in the plunger.

2. When inserting the saw blade, the back of the blade must rest in the groove of the guide roller.

Note: If the saw blade cannot be inserted into the plunger because the slots of the blade holder are not positioned correctly or the precision control guides are shut, push the blade ejector lever briefly to the front and release.

Removal:

1. Hold the tool so that the blade can be safely ejected.

2. Push the ejector lever to the center stop. This releases the precision control guides and ejects the saw blade.

The precision control guides were designed to improve the vertical cut accuracy of the saw blade. To use this feature, simply press the precision control button to close the guides. The saw blade is then guided laterally by the precision control guides, which enables precision cuts. This feature can be used for all applications, including bevel cuts, and is recommended for cuts in thick wood to maintain the cutting angle and reduce blade run-out.

A vacuum hose adapter tube and dust shroud (optional accessory) can be attached for dust and chip extraction. The adapter tube must only be used with the dust shroud when connected to a vacuum.

1. Attach the vacuum hose adapter tube to the footplate.

2. When inserting the adapter tube, be sure that the plastic post of the adapter tube engages into the corresponding hole on the housing.

3. For vacuuming, a Bosch Air Sweep vacuum hose (optional accessory) can be directly connected to the vacuum hose adapter tube.

4. For maximum vacuum dust pick up, the dust shroud must be attached.

Your tool is equipped with a protective plastic overshoe that protects finer surfaces. To attach it, hook the overshoe over the front of the metal footplate and snap it into place at the rear of the footplate.

To minimize splintering of the top surface of the material being cut, place the anti-splinter insert in the blade opening of the footplate. The insert can be placed in two positions:

• For narrow saw blades, place the insert completely to the front of the opening.

• For wider saw blades, place the insert completely to the rear of the opening.

Note: This insert will only work with blades that have ground sides such as T301CD, T101B, T101D, and T101DP.

Your BOSCH 1590EVS jigsaw can be turned “ON” or “OFF” by squeezing or releasing the trigger. It is also equipped with a “Lock-ON” button located just above the trigger for continuous operation.

TO LOCK SWITCH ON: Squeeze the trigger fully, depress the “Lock-ON” button, and then release the trigger.

TO UNLOCK THE SWITCH: Squeeze the trigger and release it without depressing the “Lock-ON” button.

The internal electronic feedback system on the BOSCH 1590EVS provides a “soft start,” which reduces the stresses from a high torque start. The system also maintains the selected speed under load for maximum efficiency.

The BOSCH 1590EVS is equipped with a variable speed dial. The blade stroke rate may be adjusted during cutting by presetting the dial on or between any one of the six numbers.

Setting	SPM rating (strokes per minute)
1	500
2	500-800
3	500-1400
4	500-1900
5	500-2400
6	500-2800

Maximum cutting efficiency can be obtained by adjusting the blade orbit selector lever to suit the material being cut. Test cuts in scrap material should be performed first to determine the best setting.

Setting 0: For hard materials such as metals or thin sheet metals. This setting can be used with knife blades, grit edge blades, rasp work and down cutting blades.

Setting 1: For soft materials where cleaner cutting or delicate scrolling work is performed.

Setting 2: For medium density materials such as harder woods or particle board.

Setting 3: For soft materials such as wood, plastics, etc., and when fast cutting is more important than a clean cut.

The BOSCH 1590EVS jigsaw has a two-position chip blower to help keep the cutting line clear of chips. By adjusting the chip blower lever, the force of the discharge air can be altered.

• BLOWER SWITCHED ON: For working with wood, plastic, and similar materials that produce large amounts of sawdust.

• BLOWER SWITCHED OFF: For working with metals, when cooling agents are used, or with the dust collection accessory.

The footplate may be tilted up to 45° in either direction to allow for angle cuts.

1. Remove the dust shroud if used.

2. Open the footplate lock lever.

3. Slide the footplate slightly forward towards the front of the tool, then rotate to the desired angle.

4. The detent slots will hold the footplate firmly at 45°, with additional position marks for 15°, 22.5°, and 30° angles. Intermediate angles can be set with a protractor.

5. After positioning the footplate, close the footplate lock lever to securely tighten the adjustment.

Note: If the footplate cannot be adjusted or you have difficulty after the lock lever has been released, rotate the tension wheel in the “-” direction. If the lock lever does not securely tighten the footplate after being closed, open the lock lever and rotate the tension wheel in the “+” direction until the desired tension is achieved.

To allow the saw to make a perpendicular cut close to a vertical surface, the footplate can be repositioned. Note that when the footplate is retracted, only 90° cuts are possible, and the optional cutting guide and anti-splinter insert guide may not be used.

1. To adjust the footplate, remove the dust shroud and anti-splinter insert.

2. Open the footplate lock lever.

3. Move the footplate back in the 0° alignment slot.

4. Close the footplate lock lever to secure the adjustment.

Plunge cutting is useful for making rough openings in softer materials without drilling a pilot hole. Do not attempt to plunge cut into hard materials such as steel.

1. Draw the lines for the opening on the workpiece.

2. Hold the saw firmly and tilt it forward so that the toe of the saw foot rests on the work, but with the blade well clear of the work.

3. Start the motor, and then very gradually lower the blade.

4. When the blade touches the work, continue pressing down on the toe of the saw foot, slowly pivoting the saw like a hinge until the blade cuts through and the foot rests flat on the work.

5. Saw ahead on the cutting line.

The Circle and Parallel Cutting Guide accessory (not included) is used for fast and accurate straight cutting.

1. Insert the bar of the guide through the lock knob clamp, then through the slots provided in the foot, from either side, with the edge guide facing DOWN.

2. Hook the lock knob clamp onto the edge of the footplate, adjust the fence to the desired width, and securely tighten the lock knob clamp.

The Circle and Parallel Cutting Guide accessory (not included) is used for fast and accurate circle cutting.

1. Before attaching the guide, draw a circle and predrill a 13/64” center hole in the workpiece.

2. Drill or plunge cut near the circle’s edge, turn the saw off, and disconnect the plug from the power source.

3. Attach the guide to the saw with the edge guide facing UP.

4. Remove the guide pin from the end of the guide, push the pin through the hole provided in the guide, and then into the center hole of the workpiece.

5. Measure the distance from the selected hole to the blade to be equal to the circle radius.

6. Insert the plug into the power source, hold the saw firmly, squeeze the trigger, and slowly push the saw forward. To make a hole, cut from inside the circle; to make wheels or discs, cut from the outside.

Cutting Tip: Cut slowly so the blade will stay straight in the cut. Place small wedges in the cut to keep the inner circle from spreading when near the end of the cut.

To avoid accidents, always disconnect the tool from the power supply before cleaning. The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air. Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings. Certain cleaning agents and solvents like gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia, and household detergents that contain ammonia can damage plastic parts.

TOOL LUBRICATION: Your Bosch tool has been properly lubricated and is ready to use. It is recommended that tools with gears be regreased with a special gear lubricant at every brush change.

CARBON BRUSHES: To maintain peak efficiency of the motor, we recommend every two to six months the brushes be examined. Only genuine Bosch replacement brushes specially designed for your tool should be used.

BEARINGS: After about 300-400 hours of operation, or at every second brush change, the bearings should be replaced. Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating or motor failure.

If an extension cord is necessary, a cord with adequate size conductors that is capable of carrying the current necessary for your tool must be used. This will prevent excessive voltage drop, loss of power or overheating. Grounded tools must use 3-wire extension cords that have 3-prong plugs and receptacles. NOTE: The smaller the gauge number, the heavier the cord.
