Safety Instructions

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 mainsoperated (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 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.

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 operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce  personal injuries.
• 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 energising 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 jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery 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 dust collection can reduce dust-related hazards.
• 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. 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 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.
• 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 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.
• 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.
• 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.

Battery tool use and care

• 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.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• 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.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C may cause explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may  damage the battery and increase the risk of fire.

Service

• 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.
• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety information for multi-cutters

• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

• 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.

• Only use the power tool for dry sanding. Water entering a power tool will increase the risk of electric shock.

• Warning: Danger of fire! Avoid overheating the workpiece and the sander. Always empty the dust collector before taking a break from work. Sanding dust in the dust bag, microfilter, paper bag (or in the filter  bag or vacuum cleaner filter) can spontaneously combust under certain conditions, for example if flying sparks are created when sanding metals. This risk is increased if the sanding dust is mixed with paint or  polyurethane residue or with other chemical substances and if the workpiece is hot as a result of prolonged work.

• Keep hands away from the sawing area. Do not reach under the workpiece. Contact with the saw blade can lead to injuries.

• Clean the air vents on your power tool regularly. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.

• Use suitable detectors to determine if there are hidden supply lines or contact the local utility company for assistance. Contact with electric cables can cause fire and electric shock. Damaging gas lines can lead  to explosion. Breaking water pipes causes property damage.

• Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.

• When changing the application tool, wear protective gloves.Application tools can become hot when used for prolonged periods of time.

• Do not scrape any dampened materials (e.g. wallpaper) or on damp surfaces. Water entering a power tool increases the risk of electric shock.

• Do not treat the surface you will be working on with any fluids that contain solvents. Poisonous vapours may develop due to the materials heating up when being scraped.

• Take particular care when handling scrapers and blades. The application tools are very sharp. Danger of injury.

• In case of damage and improper use of the battery, vapours may be emitted. The battery can set alight or explode.
  Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.

• Do not open the battery. There is a risk of short-circuiting. u The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur,  causing the battery to burn, smoke, explode or overheat.

• Only use the battery with products from the manufacturer. This is the only way in which you can protect the battery against dangerous overload.

Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short- circuiting.

Noise/Vibration Information
Noise emission values determined according to EN 62841‑2‑4.
Typically, the A-weighted sound pressure level of the power tool is 80 dB(A). Uncertainty K = 3 dB. The noise level when working can exceed the volume stated. Wear hearing protection!

Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 62841‑2‑4:
Sanding: ah = 3.4 m/s2, K = 1.5 m/s2, Cutting with plunge cut saw blade: ah = 2.9 m/s2, K = 1.5 m/s2, Cutting with segmential saw blade: ah = 3 m/s2, K = 1.5 m/s2.
The vibration level and noise emission value given in these instructions have been measured in accordance with a standardised measuring procedure and may be used to compare power tools. They may also be used  for a preliminary estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained,  the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period.

To estimate vibration and noise emissions accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account. This may significantly reduce  vibration and noise emissions over the total working period.
Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organising workflows correctly.

Rechargeable battery

Bosch sells some cordless power tools without a rechargeable battery. You can tell whether a rechargeable battery is included with the power tool by looking at the packaging.
Charging the battery

• Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your power tool.

Note: Lithium-ion rechargeable batteries are supplied partially charged according to international transport regulations. To ensure full rechargeable battery capacity, fully charge the rechargeable battery before  using your tool for the first time.

Inserting the Battery
Push the charged battery into the battery holder until it clicks into place.
Removing the Battery
To remove the rechargeable battery, press the battery release button and pull the battery out. Do not use force to do this.
The rechargeable battery has two locking levels to prevent the battery from falling out if the battery release button is pressed unintentionally. The rechargeable battery is held in place by a spring when fitted in the  power tool. Battery charge indicator
The green LEDs on the battery charge indicator indicate the state of charge of the battery. For safety reasons, it is only possible to check the state of charge when the power tool is not in operation.
Press the button for the battery charge indicator  or to show the state of charge. This is also possible when the battery is removed.
If no LED lights up after pressing the button for the battery charge indicator, then the battery is defective and must be replaced.

Fitting/changing the application tool
Remove the application tool if one has already been fitted.
To do so, open the SDS lever (7) all the way. The application tool/accessory will be ejected.
Position the required application tool (e.g. plunge cut saw blade (12)) on the tool holder (8) so that the depressed centre is facing downwards (see figure on the graphics page,
text on the application tool should be legible from above).
When doing so, place the application tool/accessory in a position which is convenient for the job at hand. Twelve positions offset by 30° are possible for this.
Press the application tool in the required position firmly onto the clamping jaws of the tool holder until it locks automatically.

Check that the application tool is seated securely. Application tools that are attached incorrectly or are not securely fixed in place may come loose during operation, thereby putting you at risk.
Mounting and adjusting the depth stop The depth stop (11) can be used when working with segment and plunge cut saw blades.
Remove the application tool if one has already been fitted.
Slide the depth stop (11) into the required working position over the tool holder (8) and onto the collar of the power tool as far as it will go. Allow the depth stop to engage.
Twelve positions offset by 30° are possible for this.
Set the depth you wish to work at. Push the clamping lever (10) of the depth stop shut to fix the depth stop in position.

Selecting a sanding sheet
Different sanding sheets are available, depending on the material you are working with and the required surface removal rate:

Attaching/changing the sanding sheet on the sanding plate
The sanding plate (14) is fitted with a hook-and-loop fastening, allowing sanding sheets with a hook-and-loop backing to be secured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate (14) before fitting the sanding sheet (15) to facilitate maximum adhesion.
Position the sanding sheet (15) so that it is flush with one side of the sanding plate (14), then place the sanding sheet on the sanding plate and press it on firmly.
To ensure optimum dust extraction, make sure that the punched holes in the sanding sheet are aligned with the drilled holes in the sanding plate.
To remove the sanding sheet (15), take hold of it by an edge and pull it away from the sanding plate (14).
You can use all sanding sheets, polishing and cleaning fleeces from the Delta 93 mm series in the Bosch range of accessories.
Sanding accessories such as fleece/polishing felt are attached to the sanding plate in the same way.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reactions and/or cause respiratory illnesses in the user or in people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as carcinogenic, especially in conjunction with wood treatment additives (chromate, wood preservative). Materials containing asbestos may only be machined by specialists.

• Use a dust extraction system that is suitable for the material wherever possible.

• Provide good ventilation at the workplace.

• It is advisable to wear a P2 filter class breathing mask.
  The regulations on the material being machined that apply in the country of use must be observed.

• Avoid dust accumulation at the workplace. Dust can easily ignite.

Operation

Starting Operation
Switching on/off

• Make sure that you are able to press the On/Off switch without releasing the handle.

To switch on the work light, slide the on/off switch (1) forwards so that appears on the switch. The work light improves visibility in the immediate work area.

• Do not look directly into the work light; it can blind you.
  To switch on the power tool, slide the on/off switch (1) further forwards so that “I” appears on the switch.
  To switch off the power tool and the work light, slide the on/off switch (1) backwards so that “0” appears on the switch.
  Note: If the power tool shuts down automatically because the battery is flat or overheated, switch the power tool off using the on/off switch (1).
  Charge the battery or let it cool down before switching the power tool on again. Failure to do so can damage the battery.

Preselecting the orbital stroke rate
You can even preselect the required orbital stroke rate during operation using the orbital stroke rate preselection thumbwheel (5).
The required orbital stroke rate is dependent on the material and the work conditions and can be determined using practical tests.
Orbital stroke rate level “6” is recommended for sawing, cutting and sanding harder materials, such as wood or metal; orbital stroke rate level “4” is recommended for softer materials, such as plastic.
Note: For certain application tools (e.g. sanding and RIFF application tools) the orbital stroke rate should be limited to a maximum of 2/3. If the orbital stroke rate is too high, this will considerably increase the wear  on the application tool and can also lead to premature breakdown. Please take note of the information on the application tools or on the packaging of the application tool.

Working Advice

• Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
• Always wait until the power tool has come to a complete stop before placing it down.
  Note: Do not keep the ventilation slots (4) on the power tool closed when working as this will reduce the service life of the power tool.

Operating principle
The oscillating drive causes the application tool to oscillate back and forth up to 20000 times per minute. This enables precise work in the tightest of spaces.
Use a consistent, low contact pressure when performing work; otherwise, the performance will be impaired and the application tool may jam.
While working, move the power tool back and forth to prevent the application tool overheating and jamming.

Sawing

• Use only undamaged saw blades that are in perfect condition. Bent or dull saw blades can break, negatively influence the cut, or lead to kickback.
• When sawing lightweight materials, take into account the statutory provisions and recommendations of the material manufacturers.
• Plunge cuts may only be applied to soft materials, such as wood, gypsum board, etc.
  Before using HCS saw blades to saw into wood, chipboard, building materials, etc., check these saw blades for foreign objects, such as nails, screws, etc. Remove the foreign objects as required or use bi-metal saw blades.

Cutting
Note: When cutting wall tiles, please bear in mind that the application tools are subject to high wear if used for extended periods.
Sanding
The material removal rate and sanding result are primarily determined by the choice of sanding sheet, the preselected orbital stroke rate level and the contact pressure.
Only immaculate sanding sheets achieve good sanding performance and make the power tool last longer.
Be sure to apply consistent contact pressure in order to increase the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to increased sanding performance, rather it will cause more severe wear of the power tool and of the sanding sheet.
To sand corners, edges and hard-to-reach areas accurately, you can also work with the tips alone or with an edge of the sanding plate.
The sanding sheet may heat up significantly when used to sand specific points rather than entire surfaces. Reduce the orbital stroke rate and contact pressure and allow the sanding sheet to cool down at regular intervals.
Do not use a sanding sheet for other materials after it has been used to work on metal.
Use only original Bosch-sanding accessories.
Always connect a dust extraction system for sanding. Scraping
Select a high orbital stroke rate level for scraping.
Work on a soft surface (e.g. wood) at a flat angle and with low contact pressure. Failure to do so may cause the scraper to cut into the surface underneath.

Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be overloaded. If the power tool is overloaded or not kept within the permitted battery temperature range, the speed is reduced or the power tool switches off. At  reduced speed, the power tool will run again at full speed once the permitted battery temperature is reached or the load is reduced.
