General Power Tool Safety Warnings

WARNING

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed

below may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. Work area safety

a. Keep work area clean and well lit. Cluttered or 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.
f. If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of an GFCI 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

General Power Tool Safety Warnings

medication. A moment of inattention while operating power tools may result in serious personal injury.

b. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and / or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing 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 jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry 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 dust collection can reduce dust-related hazards.
h. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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 and/or remove the battery pack, if detachable, 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.
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 and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's 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, 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.
h. Keep handles and grasping surfaces dry, clean and free from oil and grease.

Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

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.

Safety Rules for Jig Saws

a. Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
b. Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control.
c. Do not drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.
d. Never leave the trigger locked "ON". Before plugging the tool in, check that the trigger lock is "OFF". Accidental start-ups could cause injury.
e. Be aware of the location and setting of the switch "Lock-ON" button. If the switch is locked "ON" during the 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.

f. 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.

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

h. Do not use dull or damaged blades. Bent blade can break easily or cause kickback.

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

j. Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications which generate dust.

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

I. 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.

Additional Safety Warnings

GFCI and personal protection devices like electrician's rubber gloves and footwear will further enhance your personal safety.

Do not use AC only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.

Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.

Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted. Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.

Risk of injury to user. The power cord must only be serviced by a Bosch Factory Service Center or Autho rized Bosch Service Station.

WARNING

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.

measures reduce the risk of starting the tool accidentally.

Blade Installation and Removal

This jigsaw is equipped with a Bosch tool-less blade changing system for fast and easy changes of T-shank blades.

Note: This jigsaw does not accept U-shank blades.

If blade is not properly installed, then the blade may unexpectedly dislodge from jigsaw when tool is energized.

1. To remove a previously-used blade, pull blade change lever until blade ejects (Fig. 2).

Blade ejects forcefully when released. Direct away from yourself or bystanders.

1. Pull the blade change lever to the point that the notch on the blade clamp's ring line up with the slot in the center of the clamp (Fig. 2).

2. Insert the saw blade (teeth in cutting direction) until it the "T" part of the blade shank is completely inserted in to the blade clamp. (When inserting the saw blade, the back of the blade must rest in the grooves in double roller guide Fig. 3.)

3. When blade change lever is released, it will spring back to its closed position.

4. Verify that the blade clamp has also returned to its closed position (which is the point where slots were previously).

Note: If the saw blade cannot be inserted into the plunger, the slots of the blade holder are not in the correct position.

Precision Control

The double roller guidance system helps to ensure minimal blade deflection.

Operating Instructions

WARNING

Disconnect the plug from the power source before making any assembly, adjustments or changing accessories. Such preventive safety

measures reduce the risk of starting the tool accidentally.

Plunger Speed

The jigsaw cutting speed or stroke rate required depends on the material being cut, the type of blade being used, and the feed rate preferred by the operator.

The best speed for a particular application is largely determined by experience though as a general rule, slower speeds are for denser materials and faster speeds for softer materials.

Note: that when the jigsaw is used at low speed settings for an extended length of time, the motor temperature will rise due to slower speeds of the internal cooling fan. In such cases, it is necessary to occasionally run the tool at full speed for a few minutes to keep the motor running at high efficiency.

Variable Speed Dial

Your Jigsaw is equipped with a variable speed dial. The blade stroke rate may be adjusted during cutting operation by presetting the dial on or between any one of the six numbers (Fig. 5).

Slide On-Off Switch (Model JS572EB only)

The tool is switched "ON" by the switch button located at the side of the motor housing. The switch locks in the "ON" position, a convenience for continuous operation (Fig. 1).

To turn the tool "ON" slide the switch button forward.

TO UNLOCK THE SWITCH, slide the switch button backward.

Variable Speed Controlled Trigger Switch (Model JS572E only)

Your tool is equipped with a variable speed trigger switch. The tool can be turned "ON" or "OFF" by squeezing or releasing the trigger. The speed can be adjusted from the minimum to maximum SPM as set on the variable speed dial by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed.

Regardless of the pressure applied on the trigger, the tool will not operate any faster than maximum speed setting selected on the variable speed dial.

"Lock-On" Button (Model JS572E only)

The "Lock-ON" button, located in the handle of your tool allows for continuous operation at maximum preset SPM without holding the trigger (Fig. 1).

TO LOCK TRIGGER "ON": squeeze trigger, depress button and release trigger.

TO UNLOCK THE TRIGGER: squeeze trigger and release it without depressing the "Lock-ON" button.

WARNING

If the "Lock-ON" button is continuously being

depressed, the trigger can not be released.

Work Light

Your tool is equipped with a work light for better visibility during operation. The tool power cord must be plugged into a power source before you activate the light. To turn light ON depress the work light ON/OFF switch. To turn light off depress the ON/OFF switch again (Fig. 1).

Operating Instructions

Constant Response Circuitry

The internal electronic feedback system provides a "soft start", which will reduce the stresses that occur from a high torque start. The system also maintains the selected speed under load for maximum efficiency.

Blade Orbit Selector Lever

Maximum cutting efficiency can be obtained by adjusting the blade orbit selector lever to suit the material being cut.

The following chart will help you determine which setting to use for your application. This chart is intended as a guideline only, and test cuts in scrap material should be performed first to determine the best setting.

Setting O

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 I

Soft materials where cleaner cutting or delicate scrolling work is performed.

Setting II

Medium density materials such as harder woods or particle board.

Setting III

Soft materials such as wood, plastics, etc. and when fast cutting is more important than a clean cut.

Chip Blower

Your jig saw is equipped with 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 may be altered as follows;

BLOWER SWITCHED ON

For working with wood, plastic and similar materials that produce large amounts of sawdust.

BLOWER SWITCHED OFF

For working with metals and when cooling agents are used, or with dust collection accessory.

Footplate Angle Adjustment

The footplate may be tilted to allow angle cuts up to 45^ in either direction (Fig. 8).

Note: before adjusting the footplate, remove dust shroud and anti-splinter if used.

Open the lock lever to unlock footplate. Push and hold the footplate firmly towards the back of tool as shown. While holding the footplate backwards tilt footplate to desired angle on bevel scale, then release pressure on footplate so it engages into detent at desired angle (Fig. 8).

FOOTPLATE 1 2 LOCK LEVER

FIG. 8

BEVEL SCALE

Operating Instructions

Your tool has detent slots the footplate will engage at 0^ & 45^ , and there are additional position marks for 15^ , 22.5^ and 30^ angles.

Close the lock lever slowly to assure that footplate is locked at the desired angle.

Tool Tips

WARNING Always hold the saw by the insulated

gripping surfaces on the front of the tool and the switch handle. Failure to hold the tool by the insulated gripping surface may result in electric shock or electrocution if sawing into a blind area where live wiring exits.

Always be certain that smaller workpieces are securely fastened to a bench or other support. Larger panels may be held in place by clamps on a bench or sawhorses.

To begin a cut, clearly mark the cutting line, and rest the front of the footplate on the work. Engage the switch, and move the blade into the work using only enough forward pressure to keep the blade cutting steadily. Do not force, as this will not make the saw cut faster; let the blade do the work.

Choose blades carefully, as the ability of the jigsaw to follow curves, provide smoother finishes, or faster cutting is directly related to the type of blade used (See your Bosch Dealer).

For tight curves it is best to use a narrow or scroll blade.

When sawing metal or similar materials, shut off chip blower and apply coolant/lubricant alongside the cutting line. Don't use extraction.

Use of reverse-tooth blade such as the Bosch T101BR requires the orbital setting to be "0" and that downward pressure be applied to the top of the saw.

Plunge cutting

Plunge cutting is useful and time-saving in making rough openings in softer materials. It is not necessary to drill a hole for an inside or pocket cut. The longest blade to be used for plunge cutting is 3-1/8" (80 mm). Footplate must be set 0° setting. (Fig. 9).

FIG. 9 max. 80 mm

Draw lines for the opening, hold the saw firmly, tilt it forward so that the toe of the saw foot rests on the work, but with the blade well clear of the work. Turn the tool on and run at top speed, and then very gradually lower the blade (Fig. 10).

FIG. 10 ① ②

When it touches, 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. Then saw ahead on the cutting line. We do not recommend plunge cutting with a scroll blade. Do not try to plunge cut into hard materials such as steel.

To make sharp corners, cut up to the corner, then back up slightly before rounding the corner. After the opening is complete, go back to each corner and cut it from the opposite direction to square it off.

Operating Instructions

JA1010 Circle and Parallel Cutting Guide

(Sold separately)

The JA1010 is used for fast and accurate straight and circle cutting. It includes the guide, two clamps A for attaching it to the jig saw, and a center pin B for guiding circle cuts. The clamps and the centering pin can be stored on the guide (Fig. 11).

One end of the clamp is used to attach the guide's bar to jig saws that have narrow tops on their footplate mounting slots (C) and the other end is used to attach the guide's bar to jig saws that have wide tops on their footplate mounting slots (D) (Fig. 12).

When possible, attach the bar to the jig saw using both clamps for enhanced grip and precision.

ATTACHING GUIDE TO JIG SAW

1. Orient the blade clamp so that the proper end is placed on the jig saw foot from either side of the tool.
2. Insert guide's bar through a clamp, then through the slots provided in foot, with the guide's fence orientated correctly for the intended application, parallel cutting or circle cutting. (If possible, place second clamp on bar from opposite side of jig saw.)
3. Place lock knob(s) on proper side of clamp(s) and securely tighten lock knob(s) on the clamp(s) (Fig. 13).

PARALLEL CUTTING

Parallel cuts can be made from 5/8" to 6" in from the edge of the workpiece.

1. The guide fence surface needs to be positioned ALONGSIDE the workpiece (Fig. 14).
2. Hook clamp(s) onto footplate, adjust fence to desired width and place lock knob(s) on proper side of clamp(s)
3. Securely tighten lock knob(s) on the clamp(s) (Fig. 13).

Operating Instructions

CIRCLE CUTTING

Circle cuts can be made from 5" to 16-1/2" in diameter

1. Determine the center point of the desired circle.

2. Drill a 3/16" (5 mm) center hole 7/8" (23 mm) deep in workpiece. (For enhanced precision, drill the hole using a drill press, if possible).

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

4. Insert guide bar through a clamp, then through the slots provided in foot, from either side of foot (Fig. 15). (If possible, place second clamp on bar from opposite side of jig saw).

5. Remove guide pin B from end of guide, push pin through proper hole provided in guide, then into center hole of workpiece. (When used with a Bosch JS572 jig saw – or the JSH180 cordless jig saw – the holes labeled for the JS572 should be used.) For other jig saws, one of the other holes should be used.

6. Measure the distance from the center of the hole to the desired circle radius. Adjust that measurement as necessary to account for the width of the blade:

7. When cutting a hole, cut from inside the intended radius.

8. When cutting wheels or discs, cut from the outside the intended radius.

9. Hook clamp(s) onto footplate, and position the guide to that adjusted radius measurement.

10. Place lock knob(s) on proper side of clamp(s) and securely tighten lock knob(s) on the clamp(s) (Fig. 13).

11. Insert jig saw's plug into power source, hold the saw firmly, squeeze trigger and slowly push the saw forward.

Fig. 15 A B

Fig. 16 W W

CIRCLE-CUTTING TIPS:

• Place small wedges W in the cut as shown in Fig. 16, to keep the inner circle from spreading when near the end of the cut.
• Use a thick jig saw blade, such as the Bosh T101TP or T144DP whenever possible.
• Make sure that the jig saw's orbital setting is at 0 (zero)
• Cut slowly so the blade will stay straight in the cut.

Maintenance

WARNING

To avoid accidents, always disconnect the battery pack from tool before servicing or cleaning.

Service

WARNING

Preventive maintenance performed by un au - thorized personnel may result in misplacing of internal wires and components which could cause serious

hazard. We recommend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station. SERVICE MEN: Disconnect tool and/or charger from power source before servicing.

Tool Lubrication

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

Carbon Brushes

The brushes and commutator in your tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend every two to six months the brush es be examined. Only genuine Bosch replace ment brushes specially designed for your tool should be used.

Bearings

Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating and motor failure.

Cleaning

CAUTION

Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through opening.

Cleaning Blade Holder

Clean the saw blade holder regularly. For this, remove the saw blade from the tool and lightly tap footplate on a level surface.

Regularly spray penetrating oil onto the saw blade holder (Fig. 17).
