(triax vector sum) and uncertainty K determined according toENIEC62841-2-3: Surface grinding and abrasive cutting: Bosch Power Tools 1 609 92A 7AL | (30.03.2022)24 | English GWS 11-125 P GWS 11-125 P GWS 15-125 CIEP

Grinding thin metal sheets or other materials that tend to easily vibrate with a large surface area can cause the noise emission value to increase by up to 15dB. Suitable, heavy damping mats can reduce the increased noise emissions. Increased noise emissions must be taken into consideration, both for the risk assessment of the noise output and for selecting suitable hearing protection. 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 com- pare power tools. They may also be used for a preliminary estimation of vibration and noise emissions. The stated vibration level and noise emission value repres- ent the main applications of the power tool. However, if the power tool is used for other applications, with different ap- plication 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 oper- ator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organising workflows correctly. Kickback stop (GWS15-125CIEP) If there is a sudden kickback in the power tool, e.g. jamming in a separating cut, the power supply to the motor will be interrupted elec- tronically. To restart the tool, set the On/Off switch (3) to the "off" po- sition and then switch the power tool on again. Restart protection (GWS15-125CIEP) The restart protection feature prevents the power tool from uncontrolled starting after the power supply to it has been interrupted. To restart the tool, set the on/off switch (3) to the "off" posi- tion and then switch the power tool on again. Soft start (GWS15-125CIEP) The electronic soft start limits the torque when the power tool is switched on and enables a smooth start-up. Note: If the power tool runs at full speed immediately after being switched on, this means that the soft start and restart protection mechanisms have failed. The power tool must be sent to the after-sales service immediately; see the "After- Sales Service and Application Service" section for ad- dresses. Constant Electronic control (GWS15-125CIEP) The Constant Electronic keeps the speed at no load and un- der load virtually consistent, guaranteeing uniform perform- ance. Speed preselection (GWS 15-125 CIEP) You can preselect the required speed using the speed preselection thumbwheel (4), even during operation. The information in the table below describes the recommended values.

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 Place the protective guard (8) onto the holder on the power tool until the coding cams of the protective guard are aligned with the holder. When doing so, press and hold the unlocking lever (1). Press the protective guard (8) onto the spindle collar un- til the shoulder of the pro- tective guard is sitting on the flange of the power tool and rotate the protective guard until it audibly clicks into place. Adjust the position of the protective guard (8) to meet the requirements of the operation. To do this, push the unlock- ing lever (1) upward and rotate the protective guard (8) into the required position. u Always position the protective guard(8) such that the two cams on the unlocking lever(1) engage in the corresponding openings on the protective guard(8). u Adjust the protective guard (8) such that sparking in the direction of the operator is prevented. u The protective guard (8) must only be adjustable while the unlocking lever (1) is actuated. Otherwise, the power tool must not be used any more under any circumstances and must be sent to the after-sales ser- vice. Note: The coding cams on the protective guard (8) ensure that only a protective guard that is suitable for the power tool can be fitted. Extraction guard for sanding For low-dust grinding of paints, lacquers and plastics in con- junction with carbide grinding heads(11), you can use the extraction guard(7). The extraction guard(7) is not suitable for machining metal. A suitable Bosch dust extractor can be connected to the ex- traction guard(7). To do so, insert the vacuum hose with dust extraction adapter into the provided receiving connec- tion of the extraction guard. Protective guard for cutting u For cutting, always use the protective guard for cutting(9) or the protective guard for grinding (8) to- gether with the cover for cutting(27). u Provide sufficient dust extraction when cutting stone. The protective guard for cutting(9) is fitted in the same way as the protective guard for grinding(8). Metal cover for cutting Fit the metal cover for cutting(27) on the protective guard for grinding(8) (see figureA): Swivel the tool retainer back (➊). Attach the cover(27) to the protective guard for grinding(8) (➋). Press the tool retainer firmly into place on the protective guard(8) (➌). To remove the cover (see figureB), press the button on the tool retainer (➊) and swivel it back (➋). Remove the cover(27) from the protective guard(8) (➌). Plastic cover for cutting Attach the plastic cover for cutting(27) to the protective guard for grinding(8) (see figureC). The cover(27) audibly and visually engages on the protective guard(8). To remove the cover (see figureD), unlock the cover(27) on the left- or right-hand side of the protective guard(8) (➊) and remove the cover (➋). Extraction guard for cutting with a guide block The extraction guard for cutting with a cutting guide(19) is fitted in the same way as the protective guard for grinding. By securing the auxiliary handle(6)/(32) with the clip through the extraction guard on the gearbox housing, the power tool is firmly attached to the extraction guard. A suit- able Bosch dust extractor can be connected to the extraction guard with a cutting guide(19). To do so, insert the vacuum hose with dust extraction adapter into the provided receiv- ing connection of the extraction guard. Note: The friction generated by the dust in the vacuum hose and accessory during extraction causes an electrostatic charge that the user may experience as static discharge (de- pending on environmental factors and their physiological state). Bosch generally recommends using an anti-static va- cuum hose (accessory) to vacuum up fine dust and dry ma- terials. Bosch Power Tools 1 609 92A 7AL | (30.03.2022)26 | English Hand guard u Always fit the hand guard (21) when working with the rubber sanding pad (22) or with the cup brush/conical brush/diamond annular cutter. Attach the hand guard(21) to the auxiliary handle(6)/(32). Standard auxiliary handle/low-vibration auxiliary handle Screw the auxiliary handle (6)/(32) on the right or left of the machine head depending on the working method. u Do not operate your power tool without the auxiliary handle(6)/(32). u Do not continue to use the power tool if the auxiliary handle (6)/(32) is damaged. Do not make any altera- tions to the auxiliary handle (6)/(32). The low-vibration auxiliary handle (32) reduces vibra- tion, enabling the tool to be used safely and more com- fortably. Fitting the Abrasive Tools u Pull the plug out of the socket before carrying out any work on the power tool. 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 (18) and all the parts to be fitted. Lock the grinding spindle with the spindle lock button (2) before clamping and releasing the abrasive tools. 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. Note: When assembling bonded grinding or cutting discs us- ing the supplied mounting flange(10) and the clamping nut(15) or quick-clamping nut(16), the use of intermediate layers is not necessary. To secure the grinding/cutting disc, place the mounting flange with O-ring(10) on the grinding spindle(18) and screw on the clamping nut(15). Pay attention to the align- ment of the clamping nut(15) depending on the grinding/ cutting disc that is being used (see figures at the beginning of the.operating manual), and tighten it with the two-pin spanner (see " Quick-clamping nut ", page26). 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. A plastic part (O-ring) is fitted around the cent- ring collar in the mounting flange (10). If the O-ring is missing or damaged, the mounting flange (10) must be replaced before operation can resume. Quick-clamping nut To change the abrasive tool easily without having to use any additional tools, you can use the quick-clamping nut (16) in- stead of the clamping nut (15). u The quick-clamping nut (16) may be used only for grinding or cutting discs. Only use quick-clamping nuts (16) that are in good work- ing order and not damaged. When screwing on, make sure that the printed side of the quick-clamping nut (16) is not facing the grinding disc; the arrow must be pointing towards the index mark (33). (33) Press the spindle lock but- ton (2) to lock the grinding spindle. To tighten the quick-clamping nut, turn the grinding disc firmly clockwise. If the quick-clamping nut has been attached correctly and is not damaged, you can loosen it by hand by turning the knurled ring an- ticlockwise. If the quick- clamping nut is stuck, do not attempt to loosen it with pliers – always use the two-pin spanner. Posi- tion the two‑pin spanner as shown in the figure. Approved abrasive 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. 1 609 92A 7AL | (30.03.2022) Bosch Power ToolsEnglish | 27 Max.
