Working safely with this ma- chine is possible only when the operating and safety information are read completely and the in- structions contained therein are strictly followed. In addition, the general safety notes in the enclosed booklet must be observed. Before using for the first time, ask for a practical demonstration. ■ Wear protective glasses and hearing protec- tion. ■ Wear additional protection equipment for your safety, such as protective gloves, sturdy shoes, hard hat and apron. ■ The dust that is produced while working can be detrimental to health, inflammable or explo- sive. Suitable safety measures are required. Examples: Some dusts are regarded as carci- nogenic. Use suitable dust/chip extraction and wear a dust protection mask. ■ Dust from light alloys can burn or explode. Al- ways keep the workplace clean, as blends of materials are particularly dangerous. ■ If the mains cable is damaged or cut through while working, do not touch the cable but im- mediately pull the mains plug. Never use the machine with a damaged cable. ■ Connect machines that are used in the open via a residual current device (RCD) with an ac- tuating current of 30 mA maximum. Do not op- erate the machine in rain or moisture. ■ When working with the machine, always hold it firmly with both hands and provide for a secure stance. ■ Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more securely than by hand. ■ Always direct the cable to the rear away from the machine. ■ Always switch the machine off and wait until it has come to a standstill before placing it down. ■ For power outage or when the mains plug is pulled, unlock the On/Off switch immediately and turn it to the Off position. This prevents un- controlled restarting. ■ The machine must be used only for dry cutting/ grinding. ■ For all work with the machine, the auxiliary handle must be mounted. Noise/Vibration Information Machine Elements For Your Safety 2 609 000 397.book Seite 2 Donnerstag, 26. August 2004 1:27 13 15 • 2 609 000 397 • TMS • 20.08.04
English - 3 ■ When performing an operation where the tool insert can run into concealed electric lines, hold the machine by the insulated handles only. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the op- erator. ■ Use suitable detectors to determine if util- ity lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock. ■ For work with grinding or cutting discs, the pro- tection guard 6 must be mounted. For work with the rubber sanding plate 13 or with the cup brush 16/disc brush/flap disc, the hand guard 12 (accessory) is to be mounted. ■ Use dust extraction when working with stone. The vacuum cleaner must be approved for ma- sonry dust. When cutting stone, use the cutting guide. ■ Do not work with materials containing asbes- tos. ■ Use only grinding tools with a permissible speed at least as high as the no-load speed of the machine. ■ Check grinding tools before use. The grinding tool must be properly mounted and turn freely. Perform a test run for at least 30 seconds with- out load. Do not use damaged, out-of-round or vibrating grinding tools. ■ Protect the grinding tool from impact, shock and grease. ■ Apply the machine to the workpiece only when switched on. ■ Keep hands away from rotating grinding tools. ■ Pay attention to the direction of rotation. Al- ways hold the machine so that sparks and grinding dust fly away from the body. ■ When grinding metal, flying sparks are pro- duced. Take care that no persons are endan- gered. Due to danger of fire, no combustible materials should be located in the vicinity (spark flight zone). ■ Be careful when cutting grooves, e. g. in struc- tural walls: See Information on Structures. ■ Blocking the cutting disc leads to jerking reac- tion forces on the machine. In this case switch off the machine immediately. ■ Observe the dimensions of the grinding discs. The hole diameter must fit mounting flange 8 (M 14), 19 (M 10). Do not use any re- ducers or adapters. ■ Never use cutting discs for rough grinding. Do not exert any lateral pressure on the cutting discs. ■ Observe the manufacturer’s instructions for mounting and using grinding tools. ■ Caution! The grinding tool runs on after the machine is switched off. ■ Do not clamp the machine in a vice. ■ Never allow children to use the machine. ■ Bosch is only able to ensure perfect operation of the machine if the original accessories in- tended for it are used. Slots in structural walls are subject to the Stand- ard DIN 1053, Part 1 or country-specific regula- tions. These regulations are to be observed under all circumstances. Before beginning work, consult the responsible structural engineer, architect or the construction supervisor. Information on Structures 2 609 000 397.book Seite 3 Donnerstag, 26.

English - 4 ■ Before any work on the machine itself, pull the mains plug. Protection Guard ■ For work with grinding or cutting discs, the pro- tection guard 6 must be mounted. Open the clamping lever 7. Place the protection guard 6 onto the spindle col- lar of the machine head as shown in the illustra- tion. The encoding keys of the protection guard must match with the respective recesses on the spindle collar. Press the protection guard onto the spindle collar until the collar of the protection guard faces against the flange of the machine and the encod- ing keys engage in the circular groove at the spin- dle collar. Rotate the protection guard 6 in clockwise direc- tion to the required position (working position). Adjust the protection guard 6 in such a man- ner that sparks are not emitted in the direc- tion of the operator. Note: Encoding keys on the protection guard 6 ensure that only a protection guard that fits the machine type can be mounted. Disassemble in the reverse sequence. Auxiliary Handle ■ For all work with the machine, the auxiliary handle must be mounted. Screw the auxiliary handle 4 on the right or left of the machine head depending on the working method. Vibration-dampening Auxiliary Handle The vibration-dampening auxiliary handle re- duces the vibrations, making operation more comfortable and secure. Do not make any alterations to the aux- iliary handle. Do not continue to use an auxiliary handle if it is damaged. Hand Guard For work with the rubber sanding plate 13 or with the cup brush 16/disc brush/flap disc, the hand guard 12 (accessory) is to be mounted. The hand guard 12 is fastened with the auxiliary handle 4. ■ Before any work on the machine itself, pull the mains plug. Use only grinding tools with a permissi- ble speed at least as high as the no-load speed of the machine. Grinding and cutting discs become very hot while working; do not touch until they have cooled. ■ Clean the grinder spindle and all parts to be mounted. For clamping and loosening the grinding tools, lock the grinder spindle 5 with the spindle lock button 3. Actuate the spindle lock button 3 only when the grinder spindle is at a standstill!

English - 5 Grinding-/Cutting Disc Observe the dimensions of the grinding discs. The hole diameter must fit mounting flange 8 (M 14), 19 (M 10). Do not use any re- ducers or adapters. When using a diamond cutting disc, take care that the direction-of-rotation arrow on the dia- mond cutting disc and the direction of rotation of the machine (direction-of-rotation arrow on the machine head) agree. For mounting, see the illustration page. Screw on the clamping nut 10 and tighten with the two-pin spanner (see Section “Quick Clamp- ing Nut”). Mounting flange for grinding spindle M 14 An O-ring (plastic part) is inserted in the mounting flange 8 around the centring collar. If the O-ring is missing or is damaged, it must in all cases be replaced (Order No. 1 600 210 039) before the mounting flange 8 is mounted. Mounting flange for grinding spindle M 10 The mounting flange 19 can be used on both sides. For diamond cutting discs it must be posi- tioned on the grind- ing spindle 5 and turned through 180°. The bore of the diamond cutting disc (Ø 20 mm) must fit the spigot of the mounting flange 19 with- out any play. Do not use any reducers or adapters. ☞ After mounting the grinding tool and be- fore switching on, check that the grind- ing tool is correctly mounted and that it can turn freely. Flap Disc (for M 14 grinder spindle) Depending on the application, remove the protec- tion guard 6 and mount the hand guard 12. Place the special mounting flange 8 (accessory, Order No. 2 605 703 028) and the flap disc on the grinder spindle 5. Screw on the clamping nut 10 and tighten with the two-pin spanner. Rubber Sanding Plate 13 Depending on the application, remove the protec- tion guard 6 and mount the hand guard 12. For mounting, see the illustration page. Screw on the round nut 15 and tighten with the two-pin spanner. Cup Brush 16/Disc Brush (for M 14 grinder spindle) Depending on the application, remove the protec- tion guard 6 and mount the hand guard 12. The grinding tool must be able to be screwed onto the grinding spindle 5 until it rests firmly against the grinder spindle flange at the end of the grinder spindle threads. Tighten with an open-end spanner. (for M 14 grinder spindle) Instead of the clamping nut 10, the quick-clamp- ing nut 11 (accessory) can be used. Grinding tools can then be mounted without using tools. The quick-clamping nut 11 may be used only for grinding and cutting discs. Use only a flawless, undamaged quick-clamp- ing nut 11. When screwing on, take care that the side with printing does not point to the grinding disc. The arrow must point to the index mark 20. Lock the grinder spindle with the spin- dle lock button 3. Tighten the quick- clamping nut by forcefully turning the grinding disc in the clockwise direction. 8 19 Quick Clamping Nut 3 20 11 2 609 000 397.book Seite 5 Donnerstag, 26. August 2004 1:27 13 18 • 2 609 000 397 • TMS • 20.08.04
English - 6 A properly tightened undamaged, quick- clamping nut can be loosened by hand turning the knurled ring by hand in an an- ticlockwise direction. Never loosen a tight quick-clamping nut with pliers but use a two-pin spanner. In- sert the two-pin spanner as shown in the illustration. All grinding tools mentioned in these operating in- structions can be used. The permissible speed [rpm] or the circumferen- tial speed [m/s] of the grinding tools used must at least match the values given in the table. Therefore, always observe the permissible rotational/circumferential speed on the label of the grinding tool. Observe correct mains voltage: The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Equipment marked with 230 V can also be con- nected to 220 V. Switching On and Off To start the machine, press the On/Off switch 1 forward. To lock-on, press the On/Off switch 1 down at the front until it engages. To switch off the machine, release the On/Off switch 1 or, when the switch is locked, briefly press down the On/Off switch 1 at the rear. ☞ Test run! Check the grinding tool before use. The grinding tool must be properly mounted and rotate freely. Perform a test run of at least 30 seconds without load. Do not use damaged, out-of-round or vibrating grind- ing tools. Constant Electronic Control (PWS 9-125 CE) Constant electronic control holds the speed con- stant at no-load and under load, and ensures uni- form working performance. Overload Protection (PWS 9-125 CE) When overloaded, the motor comes to a stop. Relieve the load on the machine immediately and allow to cool for approx. 30 seconds at the high- est no-load speed. Preselect the required speed using the thumb wheel 2 according to the table following the sec- tion “Tool Specifications” (reference values). ■ Clamp the workpiece if it does not remain sta- tionary due to its own weight. ■ Do not strain the machine so heavily that it comes to a standstill. ■ Grinding and cutting discs become very hot while working; do not touch until they have cooled. Rough Grinding The best roughing results are achieved when setting the machine at an angle of 30° to 40°. Move the machine back and forth with mod- erate pressure. In this manner, the workpiece will not become too hot, does not discolour and no grooves are formed. Never use a cutting disc for roughing. Approved Grinding Tools max.

English - 7 Flap Disc With the flap disc (accessory), curved surfaces and profiles (contour sanding) can be worked. Flap discs have a considerably higher service life than sanding sheets, lower noise level and lower sanding temperatures. Cutting When cutting, do not press, tilt or oscillate the machine. Work with moderate feed, adapted to the ma- terial being cut. Do not reduce the speed of running down cutting discs by applying sideward pressure. The direction in which the cutting is performed is impor- tant. The machine must always work in an up-grinding motion. Therefore, never move the machine in the other direction! Otherwise, the dan- ger exists of it being pushed uncon- trolled out of the cut. When cutting profiles and square pipes, it is best to start with the smallest cross section. Cutting Stone ■ The machine must be used only for dry cutting/grinding. It is best to use a diamond cutting disc. As a safety measure against jamming, use the cutting guide 17 with the special dust extraction protec- tion guard. Operate the machine with dust extraction only. In addition, wear a dust mask. The vacuum cleaner must be approved for the extraction of ma- sonry dust. Bosch provides suit- able vacuum clean- ers. Switch on the ma- chine and place the front part of the cut- ting guide on the workpiece. Slide the machine with moderate feed, adapted to the material to be worked (Figure). For cutting especially hard material, e. g., con- crete with high pebble content, the diamond cut- ting disc can overheat and become damaged as a result. This is clearly indicated by circular sparking, rotating with the diamond cutting disc. In this case, interrupt the cutting process and al- low the diamond cutting disc to cool by running freely at no-load speed for a short time. Noticeable decreasing work progress and circu- lar sparking are indications of a diamond cutting disc that has become dull. Briefly cutting into abrasive material (e. g., lime-sand brick) can re- sharpen the disc. ■ Before any work on the machine itself, pull the mains plug. ■ For safe and proper working, always keep the machine and the ventilation slots clean. In extreme working conditions, conductive dust can accumulate in the interior of the machine when working with metal. The protective insulation of the machine can be degraded. The use of a stationary extrac- tion system is recommended in such cases as well as frequently blowing out the venti- lation slots and installing a residual current device (RCD). If the machine should fail despite the care taken in manufacturing and testing procedures, repair should be carried out by an authorized after-sales service centre for Bosch power tools. In all correspondence and spare parts orders, please always include the 10-digit article number given on the nameplate of the machine. WARNING! Important instructions for con- necting a new 3-pin plug to the 2-wire cable. The wires in the cable are coloured according to the following code: Do not connect the blue or brown wire to the earth terminal of the plug.
