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 mains-operated (corded) power tool or battery-operated (cord-less) power tool.

Work area safety

  • Keep the 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 that may ignite 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 the 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 carry-ing, 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. The 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. The use of an RCD reduces the risk of electric shock.

Personal safety

  • u 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 a 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.
  • 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 and clothing 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. The 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 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. The 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 the 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 behavior 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 an 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 Warnings for Sander

  • 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.
  • 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.
  • Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
  • Always wait until the power tool has come to a complete stop before placing it down.
  • In case of damage and improper use of the battery, vapors may be emitted. Ensure the area is well-ventilated and seek medical attention should you experience any adverse effects. The vapors may irritate the respiratory system.
  • Do not open the battery. There is a risk of short-circuit-ing.
  • 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, water, and moisture. There is a risk of explosion.

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 75 dB(A). Uncertainty K=4 dB. The noise level when working can exceed 80 dB(A).

Wear hearing protection

Total vibration values ah (triax vector sum) and uncertainty K are determined according to EN 62841-2-4: ah=7 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 standardized measuring procedure detailed in EN 62841 and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions. The given 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 the hands warm, and organizing workflows correctly.

Assembly

  • 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 the risk of injury from unintentionally pressing the on/off switch.

Charging the Battery

  • Use only the chargers listed on the accessories page. Only these chargers are matched to the lithium-ion battery of your power tool.

Note

The battery is supplied partially charged. To ensure full battery capacity, fully charge the battery in the charger before using your power tool for the first time. The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging process does not damage the battery. The lithium-ion battery is protected against deep discharge by the “Electronic Cell Protection (ECP)”. When the battery is discharged, the power tool is switched off by means of a protective circuit: The application tool no longer rotates.

  • Do not continue to press the On/Off switch after the power tool has automatically switched off. The battery can be damaged.

Follow the instructions on correct disposal.
Removing the Battery (see figure A)To remove the battery (2), press the release button (1) and pull the battery back and out of the power tool. Do not use force to do this.

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 dust, 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.

Self-generated dust extraction with dust box (see figures B1–B4)
Place the dust box (3) onto the extraction outlet (10) until it clicks into place. To empty the dust box (3), pull the dust box downwards. Before opening the dust box (3), knock the dust box against a firm surface as shown in the figure to loosen the dust from the filter element. Holding the dust box (3) firmly, flap the filter element (11) upwards out of the way and empty the dust box. Use a soft brush to clean the flaps of the filter element (11).

External dust extraction (see figure C)
Attach the dust extraction adapter (12) to the extraction outlet (10). A dust extraction hose with a diameter of 19 mm can be connected to the dust extraction adapter (12).
You will find an overview of connecting to various dust ex-tractors 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.

Changing the sanding sheet (see figure D)
Remove dirt and dust from the sanding plate (5), e.g. with a brush, before attaching a new sanding sheet. 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. The sanding plate (5) is fitted with a hook-and-loop fastening, allowing sanding sheets with a similar backing to be secured quickly and easily. Tap the hook-and-loop fastening of the sanding plate (5) before fitting the sanding sheet (4) to facilitate maximum adhesion. The power tool is equipped with two sanding sheets. Depending on their state of wear, these can also be changed individually.

  • Only use the power tool when both sanding sheets are fitted.
  • Only use sanding sheets with the same grit.

Position the sanding sheet (4) so that it is flush with one side of the sanding plate (5), then place the sanding sheet on the sanding plate and press it on firmly. To remove the sanding sheet (4), take hold of it by an edge and pull it away from the sanding plate (5). You can use the Bosch delta sander sanding sheets. Sanding accessories such as fleece/polishing felt are attached to the sanding plate in the same way.

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

Application  Grit

  • For working all materials such as wood, paint, filler, varnish, hard and softwood, and chip-board 40–180
  • For pre-sanding, e.g. of rough and un-even beams and boards Coarse 40
  • For surface sanding and leveling of slight irregularities Medium 80, 120
  • For finishing and fine sanding of hardwoods Fine 180

For any finishing work, such as polishing (metal and stone in particular), use fleece/polishing felt. Different types of fleece and polishing felts should be used depending on the surface finish required on the workpiece.
Changing the sanding plate (see figure E)

  1. Push the SDS slider for sanding plate release (6) all the way to the right.
  2. Remove the sanding plate (5).
  3. Move the sanding plate (5) against the sanding plate holder from below and press it firmly into place.
  4. Push the SDS slider for sanding plate release (6) all the way to the left.

If the front tip of the sanding sheet has worn down, the entire sanding plate can be removed, rotated 120°, and put back on again for reuse.

  • Special Sanding Plates
    You can replace the standard supplied sanding plate (5) with one of the special sanding plates that are available as accessories. Special sanding plates are fitted in exactly the same way as the standard supplied sanding plate. Likewise, each sanding sheet is attached and removed in exactly the same way as the original sanding sheet.
  • Louvre Sanding Attachment (see figure F)The louver sanding attachment (14) allows you to work on areas that are particularly difficult to reach, such as slats on windows, cupboards, and doors.
  • Sanding Finger, Flat (see figure G)The flat sanding finger (15) allows you to work on narrow slits and tight gaps.
  • Sanding Finger, Oval (see figure H)
    The oval sanding finger (17) allows you to work on curves, hollow parts, and concave surfaces, such as those found on items of furniture, handrails, and radiators.

Operation

Starting Operation Inserting the battery

  • Use only original Bosch lithium-ion batteries with the voltage stated on the type plate of your power tool. Using other batteries can lead to injuries and pose a fire hazard.

Switching on/off

  • 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 (8) forward so that “1” appears on the switch. To switch off the power tool, slide the on/off switch (8) backward so that “0” appears on the switch.

Battery Charge Indicator

The battery charge indicator (7) indicates the battery’s state of charge when the power tool is switched on. It consists of three green LEDs.

LED Capacity

  • Continuous light 3 x green > 66%
  • Continuous light 2 x green 33–66%
  • Continuous light 1 x green 11–33%
  • Slowly flashing light 1 x green <11%

If no LED lights up after pressing the button then the battery is defective and must be replaced.

Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-loaded. If the power tool is overloaded or the permitted battery temperature is exceeded, the electronics of the power tool will switch off until the temperature returns to within the optimum operating temperature range. The 3 LEDs in the battery charge indicator flash quickly when the temperature of the battery is outside of the operating temperature range and/or the overload protection has been triggered.

Practical 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 a 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.

The material removal rate when sanding is primarily determined by the choice of sanding sheet. 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. Do not use a sanding sheet for other materials after it has been used to work on metal. Use only original Bosch sanding accessories.

Recommendations for Optimal Handling of the Battery

Protect the battery against moisture and water. Only store the battery within a temperature range of −20 to 50 °C. Do not leave the battery in your car in the summer, for example. Occasionally clean the ventilation slots on the battery using a soft brush that is clean and dry. A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced. Follow the instructions on correct disposal.

Maintenance and Servicing

Maintenance and Cleaning

  • 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 re-moved for transport and storage. There is the 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.
