Safety Instructions

General Power Tool Safety Warnings

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 multifunction tools

• Hold the 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.
• 
  Danger of fire! Avoid overheating the workpiece and the sander. Always empty the dust container before taking a break from work. Sanding dust in the filter bag or vacuum cleaner filter can spontaneously ignite under unfavourable conditions, such as when sparks are created when grinding metal. 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 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 accessories 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 modify or open the battery. There is a risk of short-circuiting.
• 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 in the manufacturer's products. 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.

Wear hearing protection!
Working without the Auxiliary Handle
Vibration total values a_h (triax vector sum) and uncertainty K determined according to EN 62841‑2‑4 (sanding), EN 62841‑2‑11 (sawing):
Sanding: a_h=6 m/s², K = 1.5 m/s²,
Cutting with plunge cut saw blade: a_h = 16 m/s², K = 1.5 m/ s²,
Cutting with segment saw blade: a_h = 14 m/s², K = 1.5 m/s².

Working with the auxiliary handle
Vibration total values a_h (triax vector sum) and uncertainty K determined according to EN 62841‑2‑4 (sanding), EN 62841‑2‑11 (sawing):
Sanding: a_h = 6 m/s², K = 1.5 m/s²,
Cutting with plunge cut saw blade: a_h = 20 m/s², K = 2.5 m/ s²,
Cutting with segment saw blade: a_h = 16 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 accessories 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 accessories, keeping their hands warm, and organising workflows correctly.

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. Oscillation speed level "4" is the maximum level that should be used when working with sanding accessories such as sanding sheets and sanding plates. If the oscillation speed is too high, this will considerably increase the wear of the accessory and can also lead to premature breakdown. Please take note of the information on the accessory or on the packaging of the accessory.

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.

Connecting the Dust Extraction System (see figure C)

The dust extraction system (20) is only designed for use with the sanding plate (13); it serves no purpose when used together with other accessories.
Always connect a dust extraction system for sanding.
Remove the accessory and the depth stop (15) for fitting the dust extraction system (20).

Insert the dust extraction adapter (22) into an extraction hose (18) until you hear it click into place. Connect the dust extraction adapter (22) to the extraction outlet (19) and the extraction hose (18) to a dust extractor (accessory).
You will find an overview of how to connect various dust extractors at the end of these operating instructions.
The dust extractor must be suitable for the material being worked.
When extracting dry dust that is especially detrimental to health or carcinogenic, use a special dust extractor.

Operation

Starting Operation
Switching On/Off u Make sure that you are able to press the On/Off switch without releasing the handle.
To switch on the power tool, slide the on/off switch (2) forward so that "I" appears on the switch.
The electronic soft start limits the torque when the power tool is switched on and increases the service life of the motor.
The Constant Electronic keeps the oscillation speed at no load and under load virtually consistent, guaranteeing uniform performance.
To switch off the power tool, slide the on/off switch (2) 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 (2).
Charge the battery or let it cool down before switching the power tool on again. Failure to do so can damage the battery.
The 180° light band (11) improves visibility in the immediate work area. It is automatically switched on and off with the power tool.

• Do not look directly into the worklight; it can blind you.

Preselecting the oscillation speed
You can even preselect the required oscillation speed during operation using the oscillation speed preselection thumbwheel (6).
The required oscillation speed is dependent on the material and the work conditions and can be determined using practical tests.

• A maximum oscillation speed rate level of"6" is recommended for sawing wood.
• "4" is the maximum oscillation speed rate level suitable for sanding.
• "4" is the maximum oscillation speed rate level suitable for sawing plastic and metal.

Please take note of the information concerning the maximum oscillation speed rate on the accessories or on the packaging of the accessories. Oscillation speed rate level "4" is the maximum level that should be used when working with accessories such as sanding and RIFF accessories.
Note: If the oscillation speed rate is too high, this will considerably increase the wear on the accessories and can also lead to their premature breakdown.

Working Advice

• Before carrying out any work on the power tool (e.g. maintenance, tool change etc.), remove the battery from the power tool. 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 (7) 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 accessory to oscillate back and forth by 2.8° 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 accessory may jam.

While working, move the power tool back and forth to prevent the accessory 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.
• Make sure that there are no power lines behind the workpiece to be cut.

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 accessories 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 oscillation speed 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 premature failure of the sanding plate.
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 oscillation speed 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 oscillation speed 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. In the event of excessive load or temperatures outside of the permitted battery temperature range, the power tool switches off. Switch the power tool off, allow the battery to cool down, then switch the power tool back on.

Maintenance and Service

Maintenance and Cleaning

• Before carrying out any work on the power tool (e.g. maintenance, tool change etc.), remove the battery from the power tool. There is risk of injury from unintentionally pressing the on/off switch.
• To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean. Regularly clean Riff accessories using a wire brush.
