The vibration level given in these instructions has been measured in accordance with a standardised measuring pro- cedure and may be used to compare power tools. It can also be used for a preliminary estimation of exposure to vibra- tion. Bosch Power Tools 1 609 92A 6PJ | (12.07.2021)18 | English The stated vibration level applies to the main applications of the power tool. However, if the power tool is used for differ- ent applications, with different application tools or poorly maintained, the vibration level may differ. This can signific- antly increase the exposure to vibration over the total work- ing period. To estimate the exposure to vibration accurately, the times when the tool is switched off or when it is running but not ac- tually being used should also be taken into account. This can significantly reduce the exposure to vibration over the total working period. Implement additional safety measures to protect the oper- ator from the effects of vibration, such as servicing the power tool and application tools, keeping the hands warm, and organising workflows correctly. Fitting Battery Charging u Use only the chargers listed in the technical data. 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. u 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 (seefigureA) To remove the battery(4), press the release buttons(5) and pull the battery out of the power tool. Do not use force to do this. Battery charge indicator LED Capacity Continuous lighting 3x green 60–100% Continuous lighting 2x green 30–60% Continuous lighting 1x green 10–30% Slowly flashing light 1 x green 0–10% Fitting Protective Equipment u Remove the battery from the power tool before carry- ing 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 risk of injury from unintentionally pressing the on/off switch. Note: If the grinding disc breaks during operation or the holding fixtures on the protective guard/power tool become damaged, the power tool must be sent to the after-sales ser- vice immediately; see the "After-Sales Service and Applica- tion Service" section for addresses. Protective guard for grinding u Always use the protective guard for grinding (7) when grinding. Protective guard for cutting u Always use the protective guard for cutting (10) when cutting bonded abrasives. u Provide sufficient dust extraction when cutting stone. Fitting the Protective Guard (seefigureB) Insert the protective guard for cutting(10) onto the protect- ive guard for grinding(7) until this engages firmly. Adjusting the Protective Guard (seefigureB) Turn the protective guard to the required position and en- sure the protective guard is engaged. No tool is required for this. Fitting the abrasive tools u Remove the battery from the power tool before carry- ing 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 risk of injury from unintentionally pressing the on/off switch. u Do not touch grinding and cutting discs until they have cooled down. The discs can become very hot while work- ing. Clean the grinding spindle(8) and all parts to be mounted. To tighten or loosen the abrasive tools, push the spindle lock button(2) forwards and simultaneously turn the grinding tool to fix the grinding spindle in place. u Do not press the spindle lock button while the grind- ing spindle is moving. The power tool may become dam- aged if you do this. Grinding/cutting disc Pay attention to the dimensions of the abrasive tools. The diameter of the hole must match that of the mounting flange. Do not use an adapter or reducer. When using diamond cutting discs, make sure that the direc- tion of rotation arrow on the diamond cutting disc corres- ponds to the direction of rotation of the machine (see direc- tion of rotation arrow on the housing). See the graphics page for fitting instructions. To remove the grinding/cutting disc, push the spindle lock button(2) forwards while simultaneously turning on the grinding/cutting disc(12) in order to fix the grinding spindle(8) in place (seefigureC1). Use a hex key(13) to remove the clamping bolt with washer(11) and take off the grinding/cutting disc (12) (seefigureC2). 1 609 92A 6PJ | (12.07.2021) Bosch Power ToolsEnglish | 19 To attach the grinding/cutting disc, screw in the clamping bolt with washer(11). Tighten the bolt using the hex key(13) until the washer of the bolt is flush with the grind- ing/cutting disc(12) (seefigureC3). Then push the spindle lock button(2) back again (seefigureC4). u After fitting the abrasive tool, check that the abrasive tool is fitted correctly and can turn freely before switching on the power tool. Make sure that the abras- ive tool does not brush against the protective guard or other parts. Approved Grinding Tools You can use all the abrasive tools mentioned in these operat- ing instructions. The permissible speed [min

] or the circumferential speed [m/s] of the abrasive tools used must at least match the val- ues given in the table. It is therefore important to observe the permissible rota- tional/circumferential speed on the label of the abrasive tool. max. [mm] [mm] D b d [min
