Safety Notesa

General Power Tool Safety

WARNING: Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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.

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 and moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an exten-sion 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 unavoid-able, use a residual current device (RCD) protected supply. Use of an RCD 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. A moment of inattention while op-erating power tools may result in serious personal injury.
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 inju-ries.
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 en-ergising power tools that have the switch on invites acci-dents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a ro-tating part of the power tool may result in personal injury.
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 inju-ries.
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 en-ergising power tools that have the switch on invites acci-dents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a ro-tating part of the power tool may result in personal injury.

Power tool use and care

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.
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.
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. Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or bind-ing 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.
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 ac-cordance 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.

Service

Have your power tool serviced by a qualified repair per-son using only identical replacement parts. This will en-sure that the safety of the power tool is maintained.

Safety Warnings for Jigsaws

Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting ac-cessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Keep hands away from the sawing range. Do not reach under the workpiece. Contact with the saw blade can lead to injuries.
Apply the machine to the workpiece only when switched on. Otherwise there is danger of kickback when the cutting tool jams in the workpiece.
Pay attention that the base plate 5 rests securely on the material while sawing. A jammed saw blade can break or lead to kickback.
When the cut is completed, switch off the machine and then pull the saw blade out of the cut only after it has come to a standstill. In this manner you can avoid kick-back and can place down the machine securely.
Use only undamaged saw blades that are in perfect con-dition. Bent or dull saw blades can break, negatively influ-ence the cut, or lead to kickback.
Do not brake the saw blade to a stop by applying side pressure after switching off. The saw blade can be dam-aged, break or cause kickback.
Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explo-sion. Penetrating a water line causes property damage or may cause an electric shock.
Secure the workpiece. A workpiece clamped with clamp-ing devices or in a vice is held more secure than by hand.
Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.
Products sold in GB only: Your product is fitted with a BS 1363/A approved electric plug with internal fuse
(ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorised customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains socket elsewhere.
Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current of 30 mA or less.

Technical Data

Noise/Vibration Information
Sound emission values determined according to
EN 60745-2-11.
Typically the A-weighted noise levels of the product are: Sound pressure level 88 dB(A); Sound power level 99 dB(A). Uncertainty K =3 dB.

Wear hearing protection

Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-11:
Sawing chipboard: ah=8.6 m/s2, K=1.5 m/s2,
Sawing sheet metal: ah=9.5 m/s2, K=1.5 m/s2.
The vibration level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and may be used to compare one tool with anoth-er. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main ap-plications of the tool. However if the tool is used for different applications, with different accessories or insertion tools or is poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may sig-nificantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work pat-terns.

Assembly

Before any work on the machine itself, pull the mains plug.

Replacing/Inserting the Saw Blade

When mounting the saw blade, wear protective gloves. Danger of injury when touching the saw blade.

Selecting a Saw Blade
An overview of recommended saw blades can be found at the end of these instructions. Use only T-shank saw blades. The saw blade should not be longer than required for the intended cut.
Use a thin saw blade for narrow curve cuts.

Inserting the Saw Blade (see figure A1)
Insert the saw blade 8 (teeth in cutting direction) into the stroke rod 11 until it latches. The SDS lever 12 automatically snaps to the rear and the saw blade is locked. Do not manually press the lever 12 toward the rear, otherwise you could dam-age the machine.
While inserting the saw blade, pay attention that the back of the saw blade is positioned in the groove of the guide roller 7.

Check the tight seating of the saw blade. A loose saw blade can fall out and lead to injuries.

Ejecting the Saw Blade (see figure A2)

When ejecting the saw blade, hold the machine in such a manner that no persons or animals can be injured by the ejected saw blade.

Turn the SDS lever 12 toward the front in the direction of the contact protector 9. The saw blade is released and ejected.

Splinter Guard (see figure B) The splinter guard 13 (accessory) can prevent fraying of the surface while sawing wood. The splinter guard can only be used for certain saw blade types and only for cutting angles of 0°. When sawing with the splinter guard, the base plate 5 must not be moved back for cuts that are close to the edge.

Press the splinter guard 13 from the bottom into the base plate 5.

Dust/Chip Extraction

Dusts from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dusts can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are considered as carcinogenic, especially in connection with wood-treat-ment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
- Provide for good ventilation of the working place.
- It is recommended to wear a P2 filter-class respirator. Observe the relevant regulations in your country for the materials to be worked.
Prevent dust accumulation at the workplace. Dusts can

Operation

Operating Modes

Before any work on the machine itself, pull the mains plug.

Orbital Action Settings
The four orbital action settings allow for optimal adaptation of cutting speed, cutting capacity and cutting pattern to the ma-terial being sawed.
The orbital action can be adjusted with the adjusting lever 6, even during operation.

Setting: 0 No orbital action
Setting: I Small orbital action
Setting: II Medium orbital action
Setting: III Large orbital action

The optimal orbital action setting for the respective application can be determined through practical testing. The following recommendations apply:

Select a lower orbital action setting (or switch it off) for a finer and cleaner cutting edge.
For thin materials such as sheet metal, switch the orbital action off.
For hard materials such as steel, work with low orbital action.
For soft materials and when sawing in the direction of the grain, work with maximum orbital action.

Adjusting the Cutting Angle (see figure C)

Loosen the screw 15 and lightly slide the base plate 5 in the direction of the mains cable.
For adjustment of precise mitre angles, the base plate has adjustment notches on the left and right at 0° and 45°. Swivel the base plate 5 to the desired position according to the scale 14. Other mitre angles can be adjusted using a protractor.

Afterwards, push the base plate 5 to the stop in the direction of the saw blade 8.
Tighten the screw 15 again.
The splinter guard 13 can not be inserted for mitre cuts

Offsetting the Base Plate (see figure C)

For sawing close to edges, the base plate 5 can be offset to the rear.
Loosen the screw 15 and slide the base plate 5 to the stop toward the mains cable.
Tighten the screw 15 again.
Sawing with the base plate 13 offset is possible only with a mitre angle of 0°. The splinter guard 13 may not be used.

Starting Operation
Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230 V can also be operated with 220 V.

Switching On and Off

To start the machine, press the On/Off switch 3.
To lock the On/Off switch 3, keep it depressed and push the lock-on button 1 to the right or left.
To switch off the machine, release the On/Off switch 3. When the On/Off switch 3 is locked, press it first and then release it.
To save energy, only switch the power tool on when using it.
Controlling/Presetting the Stroke Rate
Increasing or reducing the pressure on the On/Off switch 3 enables stepless stroke-rate control of the switched-on machine. Light pressure on the On/Off switch 3 results in a low stroke rate. Increasing the pressure also increases the stroke rate.
When the On/Off switch 3 is locked, it is not possible to reduce the stroke rate.
With the thumbwheel for stroke rate preselection 2, the stroke rate can be preset and changed during operation.
The required stroke rate is dependent on the material and the working conditions and can be determined by a practical trial. Reducing the stroke rate is recommended when the saw blade engages in the material as well as when sawing plastic and aluminium.
After longer periods of work at low stroke rate, the machine can heat up considerably. Remove the saw blade from the machine and allow the machine to cool down by running it for approx. 3minutes at maximum stroke rate.

Working Advice

Before any work on the machine itself, pull the mains plug.
When working small or thin work pieces, always use a sturdy support or a saw table (accessory).

Check wood, press boards, building materials, etc. for foreign objects such as nails, screws or similar, and remove them, if required.

Contact Protector
The contact protector 9 attached to the casing prevents acci-dental touching of the saw blade during the working proce-dure and may not be removed.

Plunge Cutting (see figure D)

The plunge cutting procedure is only suitable for treat-ing soft materials such as wood, plaster board or simi-lar! Do not work metal materials with the plunge cut-ting procedure!

Use only short saw blades for plunge cutting. Plunge cutting is possible only with the mitre angle set at 0°.
Place the machine with the front edge of the base plate 5 on to the workpiece without the saw blade 8 touching the work-piece and switch on. For machines with stroke rate control, select the maximum stroke rate. Firmly hold the machine against the workpiece and by tilting the machine, slowly plunge the saw blade into the workpiece.
When the base plate 5 fully lays on the workpiece, continue sawing along the desired cutting line.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied alongside cutting line because of the material heating up.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull the mains plug.
For safe and proper working, always keep the machine and ventilation slots clean.

If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in or-der to avoid a safety hazard.
Clean the saw blade holder regularly. For this, remove the saw blade from the machine and lightly tap out the machine on a level surface.
Heavy contamination of the machine can lead to malfunc-tions. Therefore, do not saw materials that produce a lot of dust from below or overhead.

In extreme conditions, always use dust extraction as far as possible. Blow out ventilation slots frequently and install a portable residual current device (PRCD). When working metals, conductive dust can settle in the in-terior of the power tool. The total insulation of the power tool can be impaired.
Lubricate the guide roller 7 occasionally with a drop of oil.
Check the guide roller 7 regularly. If worn, it must be replaced through an authorised Bosch after-sales service agent.
