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. 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.

Low Energy Module. Charging the Battery u Use only the chargers listed on the accessories page. Only these chargers are matched to the lithium-ion bat- tery 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 The battery (8) is equipped with two locking levels to pre- vent the battery from falling out when pushing the battery re- lease button (9) unintentionally. As long as the battery is in- serted in the power tool, it is held in position by means of a spring.

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 advice on using products" section for addresses. Protective guard for grinding Place the protective guard (11) 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 unlock- ing lever (1). Press the protective guard (11) onto the spindle collar until the shoulder of the protective guard is sitting on the flange of the power tool and rotate the protect- ive guard until it audibly clicks into place. Adjust the position of the protective guard (11) to meet the requirements of the operation. To do this, push the unlock- ing lever (1) upward and rotate the protective guard (11) into the required position. u Always position the protective guard (11) such that all three red cams on the unlocking lever (1) engage in the corresponding openings on the protective guard (11). u Adjust the protective guard (11) such that sparking in the direction of the operator is prevented. u The protective guard (11) 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 (11) ensure that only a protective guard that is suitable for the power tool can be fitted. Protective guard for cutting u Always use the protective guard for cutting (16) when cutting bonded abrasives. u Provide sufficient dust extraction when cutting stone. The protective guard for cutting (16) is fitted in the same way as the protective guard for grinding (11).Extraction guard for cutting with a guide block The extraction guard for cutting with a guide block (30) is fit- ted in the same way as the protective guard for grinding (11). Side handle u Do not operate your power tool without the side handle (10). Screw the side handle (10) on the left or right of the ma- chine head depending on how your are working. Low-vibration auxiliary handle The low-vibration auxiliary handle reduces vibration, enabling the tool to be used safely and more comfort- ably. u Do not make any alterations of any kind to the auxili- ary handle. Do not continue to use a damaged auxiliary handle. Hand guard u Always fit the hand guard (20) when working with the rubber sanding pad (21) or with the cup brush/disc brush/flap disc. Attach the hand guard (20) to the side handle (10). 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 (19) and all the parts to be fitted. Lock the grinding spindle with the spindle lock button (3) 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 hub flange. Do not use an adapter or reducer. When using diamond cutting discs, ensure that the arrow in- dicating the direction of rotation on the diamond cutting disc matches the direction of rotation of the power tool (see the direction of rotation arrow on the machine head). See the graphics page for fitting instructions. Use the quick-clamping nut (14) to secure the grinding/cut- ting disc without the need for additional tools. Only use the quick-clamping nut (14) for grinding/cutting discs up to a maximum diameter of 150mm. u The quick-clamping nut (14) may be used only for grinding or cutting discs. u Only use quick-clamping nuts (14) that are in good working order and not damaged. u When screwing on, make sure that the printed side of the quick-clamping nut (14) is not facing the grinding disc. u Always secure a grinding/cutting disc using only the quick-clamping nut (14) supplied. Press the spindle lock but- ton (3) to lock the grinding spindle. To tighten the quick-clamping nut (14), fold up the bar and turn the quick-clamping nut firmly clockwise. Then fold down the bar to secure the quick- clamping nut. It is not suf- ficient to tighten the disc along the edge. Quick-clamping nuts (14) that are properly secured and not damaged can be re- moved by hand. To do this, fold up the bar and turn the quick-clamping nut firmly anticlockwise. If the quick- clamping nut is stuck, do not attempt to loosen it with a tool – always use a two- pin spanner. After fitting the hub flange and the grinding/cutting disc, the free thread length of the grinding spindle must be at least 4mm. Ensure that the abrasive tool is firmly seated, so that it does not twist away from the spindle in the runout of the power tool. A plastic part (O-ring) is fitted around the cent- ring collar in the hub flange (12). If the O-ring is missing or damaged, the hub flange (12) must be replaced before operation can re- sume. 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.

Tighten the cup brush/disc brush with an open-ended spanner. Carbide Grinding Head u A grinding head may be used only with a suitable pro- tective guard. Approved abrasive tools You can use all the abrasive tools mentioned in these operat- ing instructions. The permissible speed [rpm] 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 [rpm] [m/s]

82 – M 14 9000 80 Rotating the Machine Head (GWS 18V-10 C) 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. The machine head can be rotated in 90° increments. In this way, the on/off switch can be brought into a more favourable handling position for particular ap- plications, e.g. for left- handed tool users. Completely unscrew the four screws. Rotate the ma- chine head carefully, without removing it from the hous- ing, into the new position. Screw in and retighten the four screws. Dust/Chip Extraction Dust from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dust, such as oak or beech dust, is considered carci- nogenic, especially in connection with wood-treatment ad- ditives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists. – Provide for good ventilation of the working place. – It is recommended to wear a P2 filter-class respirator. Observe the relevant regulations in your country for the ma- terials to be worked. u Avoid dust accumulation at the workplace. Dust can easily ignite.

Switching on/off To start the power tool, push the on/off switch (6) forward.To lock the on/off switch (6) in position, push the on/off switch (6) forward and down until it clicks into place. To switch off the power tool, release the on/off switch (6); or, if the switch is locked, briefly push the on/off switch (6) backward and down and then release it. u Always check abrasive tools before using them. The abrasive tool must be fitted properly and be able to move freely. Carry out a test run for at least one minute with no load. Do not use abrasive tools that are damaged, run untrue or vibrate during use. Damaged abrasive tools can burst apart and cause injuries. Kickback stop 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. The LED work light (4) then flashes white and the status indicator (35) flashes red. To restart the tool, set the on/off switch (6) to the off posi- tion and then switch the power tool on again. Restart protection The restart protection feature prevents the power tool from uncontrolled starting after the power supply to it has been interrupted. When restart protection is activated, the status indicator (35) flashes red. To restart the tool, set the on/off switch (6) to the off posi- tion and then switch the power tool on again. Impact shutdown The integrated impact shutdown switches the power tool off as soon as it hits the floor. The status indicator (35) then flashes red. To restart the tool, set the on/off switch (6) to the off position and then switch the power tool on again. User interface (see figure D) The user interface (5) is used to preselect the speed and to indicate the status of the power tool. Speed Preselection (GWS 18V-10 SC) You can use the button for speed preselection (34) to preselect the required speed, even during operation.

Low Energy Module. Practical advice u With the GCY 30-4 Bluetooth

Low Energy Module, the power tool is equipped with a radio interface. Local operating restrictions, e.g. in aircraft or hospitals, must be observed. u Exercise caution when cutting slots in structural walls; see the "Information on structures" section. u Clamp the workpiece if it is not secure under its own weight. u Do not load the power tool so heavily that it comes to a stop. u If the power tool has been subjected to a heavy load, continue to run it at no-load for several minutes to cool down the accessory. u Do not use the power tool with a cut-off stand. u Do not touch grinding and cutting discs until they have cooled down. The discs can become very hot while work- ing. If the power tool becomes electrostatically charged, the built-in electronics will switch the power tool off. Press the on/off switch (6) again to restart the power tool. Rough grinding u Never use cutting discs for rough grinding. The best rough grinding results are achieved with a set angle of 30° to 40°. Move the power tool back and forth with mod- erate pressure. This will ensure that the workpiece does not become too hot or discolour and that grooves are not formed. Flap disc The flap disc (accessory) enables you to machine curved surfaces and profiles. Flap discs have a considerably longer service life, lower noise levels and lower sanding temperatures than conven- tional grinding discs. Cutting metal u Always use the protective guard for cutting (16) when cutting bonded abrasives. When carrying out abrasive cutting, use a moderate feed that is suited to the material being machined. Do not exert pressure on the cutting disc and do not tilt or swing the power tool. Do not attempt to reduce the speed of a cutting disc coming to a stop by applying pressure from the side. The power tool must always work in an up-grinding mo- tion. Otherwise there is a risk that it will be pushed uncontrolled out of the cut. For best results when cut- ting profiles and rectangular tubing, start at the smallest cross section. Cutting Stone (see figure
