(triax vector sum) and uncertainty K determined according to EN 60745:

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of expo- sure. The declared vibration emission level represents the main ap- plications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly in- crease the exposure level over the total working period. An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may sig- nificantly reduce the exposure level over the total working pe- riod. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep hands warm, organise work patterns. Declaration of Conformity We declare under our sole responsibility that the product de- scribed under “Technical Data” is in conformity with the fol- lowing standards or standardization documents: EN 60745 according to the provisions of the directives 2011/65/EU, 2004/108/EC, 2006/42/EC.

Assembly Inserting a Router Bit (see figure A) f Before any work on the machine itself, pull the mains plug. f It is recommended to wear protective gloves when in- serting or replacing router bits. Depending on the application, router bits are available in the most different designs and qualities. Router bits made of high speed steel (HSS) are suitable for the machining of soft materials, e. g. softwood and plastic. Carbide tipped router bits (HM) are particularly suitable for hard and abrasive materials, e. g. hardwood and aluminium. Original router bits from the extensive Bosch accessories pro- gram are available at your specialist shop. Only use clean router bits that are in perfect condition. – Fold the chip shield 6 down. – Push the spindle lock lever 4 in clockwise direction and hold it in this position (n). If required, turn the motor spin- dle by hand until it is locked. – Loosen the tightening nut 23 with the open-end spanner 25 (size 24 mm) by turning in antclockwise direction (o). – Insert the router bit into the collet. The shank of the router bit must be immersed at least 20 mm into the collet. – Tighten the tightening nut 23 with the open-end spanner 25 (size 24 mm) by turning in clockwise direction. Release the spindle lock lever 4. – Fold the chip shield 6 up again. f Do not insert a router bit with a diameter larger than 50 mm when the guide bushing is not mounted. Such router bits do not fit through the base plate. f Do not tighten the tightening nut of the collet without a router bit inserted. Otherwise the collet can be damaged. Dust/Chip Extraction (see figure B) f Dusts 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 dusts can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dusts, such as oak or beech dust, are considered as carcinogenic, especially in connection with wood-treat- ment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists. – As far as possible, use a dust extraction system suita- ble for the material. – 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 materials to be worked. f Prevent dust accumulation at the workplace. Dusts can easily ignite. Mounting the Extraction Adapter The extraction adapter 27 can be mounted with the hose con- nection to the front or to the rear. When the guide bushing adapter 44 is mounted, it is possible that the guide bushing adapter must be turned by 180° so that the extraction adapt- er 27 does not touch the release lever 46. When mounting with the hose connection in front, the chip shield 6 must be removed first. Fasten the extraction adapter 27 with the 2 knurled screws 28 to the base plate 12. Connecting the Dust Extraction Insert an extraction hose (Ø 35 mm) 26 (accessory) into the mounted extraction adapter. Connect the extraction hose 26 to a vacuum cleaner (accessory).

The vacuum cleaner starts automatically when the ma- chine is switched on. The vacuum cleaner must be suitable for the material being worked. When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a special vacuum cleaner. Mounting the Chip Shield (see figure C) Insert the chip shield 6 from the front into the guide in such a manner that it engages. To remove the chip shield, grasp it by the sides and pull it off toward the front. Operation Starting Operation f Observe correct mains voltage! The voltage of the pow- er source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230 V can also be operated with 220 V. Preselecting the Speed The required speed can be preselected with the thumbwheel 3 (also while running). 1 – 2 low speed 3 – 4 medium speed 5 – 6 high speed The values shown in the chart are standard values. The neces- sary speed depends on the material and the operating condi- tions, and can be determined by practical testing. After longer periods of working at low speed, allow the ma- chine to cool down by running it for approx. 3 minutes at max- imum speed with no load. Switching On and Off Adjust the depth-of-cut before switching on or off; see Sec- tion “Adjusting the Depth-of-cut”. To start the machine, press the On/Off switch 24 and keep it pressed. To lock the pressed On/Off switch 24, press the lock-on but- ton 2. To switch off the machine, release the On/Off switch 24 or when it is locked with the lock-on button 2, briefly press the On/Off switch 24 and then release it. Constant Electronic Control Constant electronic control holds the speed constant at no- load and under load, and ensures uniform working perform- ance. Soft Starting The electronic soft starting feature limits the torque upon switching on and increases the working life of the motor. Adjusting the Depth-of-cut (see figure D) f The adjustment of the depth-of-cut may only be carried out when the router is switched off. For coarse adjustment of the depth-of-cut, proceed as follows: – Place the machine with the router bit mounted on the workpiece to be machined. – Set the fine-adjustment path to the centre position with the adjustment knob 20. For this, turn the adjustment knob 20 until the marks 21 match as shown in the figure. Afterwards, set the scale 19 to “0”. – Set the step buffer 10 to the lowest position; the step buff- er engages noticeably. – Loosen the wing bolt for the depth stop 14 so that the depth stop 15 can be moved freely. – Push the release lever 22 downward and slowly lower the plunge router until the router bit 7 touches the surface of the workpiece. Let go of the release lever 22 again to lock this plunging depth. – Push the depth stop 15 downward until it rests on the step buffer 10. Set the slide with the index mark 16 to the “0” position on the scale for the depth-of-cut adjustment 18. – Set the depth stop 15 to the required depth-of-cut and tighten the wing bolt for the depth stop 14. Pay attention not to misadjust the slide with the index mark 16 again. – Push the release lever 22 and guide the plunge router to the uppermost position. For deep cuts, it is recommended to carry out several cuts, each with little material removal. By using the step buffer 10, the cutting process can be divided into several steps. For this, adjust the desired depth-of-cut with the lowest step of the step buffer and select the higher steps first for the initial cuts. The clearance of the steps can be changed by screwing the adjusting screws 11 further in or out. After a trial cut, the depth-of-cut can be set exactly to the de- sired measure by turning the adjustment knob 20; turn in clockwise direction to increase the cutting depth and in anti- clockwise direction to decrease the cutting depth. The scale 19 can be used for guidance.

OBJ_BUCH-203-004.book Page 18 Wednesday, November 23, 2011 9:50 AMEnglish | 19 Bosch Power Tools 1 619 929 J79 | (23.11.11) setting range of 2.0 mm; a graduation mark on the top edge of the scale 19 corresponds with a 0.1 mm change of the setting range. The maximum setting range is ± 8mm. Example: The desired depth-of-cut is to be 10.0 mm; the trial cut resulted in a cutting depth of 9.6 mm. – Lift up the router and place e. g. a piece of scrap wood un- der the guide plate 9 so that the router bit 7 cannot touch the workpiece when lowering it. Push the release lever 22 down and slowly lower the plunge router until the depth stop 15 faces on the step buffer 10. –Turn the scale 19 to “0” and loosen wing bolt 14. – Turn the adjustment knob 20 by 0.4 mm/4 graduation marks (difference from set to actual value) in clockwise di- rection and tighten the wing bolt 14. – Check the selected depth-of-cut by carrying out another trial cut. After adjusting the depth-of-cut, do not change the position of the slide 16 on the depth stop 15 any more, so that the actual cutting depth can be read on the scale 18. Working Advice f Protect router bits against shock and impact. Direction of Feed and Routing Process (see figure E) f The routing process must always be carried out against the rotation direction of the router bit 7 (up-cutting motion). When routing in the direction with the rota- tion of the router (down-cutting), the machine can break loose, eliminating control by the user. – Adjust the required depth-of-cut; see Section “Adjusting the Depth-of-cut”. – Place the machine with the router bit mounted on the workpiece to be machined and switch the power tool on. – Push the release lever 22 down and slowly lower the plunge router until the adjusted depth-of-cut is reached. Let go of the release lever 22 again to lock this cutting depth. – Carry out the routing process applying uniform feed. – After finishing the cutting process, guide the plunge router upward again to the uppermost position. – Switch the power tool off. Routing with Auxiliary Guide (see figure F) For working large workpieces, e. g. when routing grooves, a board or wood strip can be fastened to the workpiece as an auxiliary guide alongside which the router can be guided. Guide the router with the flattened side of the guide plate along the auxiliary guide. Shaping or Molding Applications For shaping or molding applications without the use of a par- allel guide, the router bit must be equipped with a pilot or a ball bearing. – Guide the switched on power tool from the side toward the workpiece until the pilot or the ball bearing of the router bit faces against the workpiece edge to be machined. – Guide the power tool alongside the workpiece edge with both hands, paying attention that the router is positioned rectangular. Too much pressure can damage the edge of the workpiece. Routing with Parallel Guide (see figure G) Slide the parallel guide 29 with the guide rods 30 into the base plate 12 and tighten as required with the wing bolts 5. Additionally, the parallel guide can be adjusted lengthwise with the wing bolts 31 and 32. Fine adjustment of the length is possible with the fine-adjust- ment knob 33 after loosening both wing bolts 31. One revolu- tion corresponds with a setting range of 2.0 mm. One gradu- ation mark on the fine-adjustment knob 33 changes the setting range by 0.1 mm. The effective contact surface of the parallel guide can be ad- justed with the edge guide 34. Guide the switched on power tool with uniform feed and later- al pressure on the parallel guide alongside the workpiece edge. When routing with the parallel guide 29, the dust/chip extrac- tion should take place via the special extraction adapter for the parallel guide 35. The extraction adapter 27 can remain mounted. Routing with the Router Compass (see figure H) The router compass/guide-rail adapter 36 can be used for cir- cular routing jobs. Mount the router compass as shown in the figure. Screw the centring screw 41 into the thread on the router compass. Insert the point of the centring screw into the cen- tre of the circular arc to be routed, paying attention that point of the screw engages into the workpiece surface. Coarsely adjust the required radius by moving the router com- pass and tighten the wing bolts 38 and 39. The length can be fine adjusted with the fine-adjustment knob 40 after loosening the wing bolt 39. One revolution corre- sponds with a setting range of 2.0 mm. One graduation mark on the fine-adjustment knob 40 changes the setting range by

Guide the switched on power tool over the workpiece with the right handle 1 and the router compass handle 37. Routing with Guide Rail (see figure I) Straight routing cuts can be carried out with help of the guide rail 43. The base spacer 42 must be mounted in order to compensate the height difference. Mount the router compass/guide-rail adapter 36 as shown in the figure. Fasten the guide rail 43 to the workpiece with suitable clamp- ing devices, e. g. screw clamps. Place the machine with the guide-rail adapter 36 mounted onto the guide rail. Routing with Guide Bushing (see figures K–N) The guide bushing 47 enables template and pattern routing on workpieces. In order to use the guide bushing 47, the guide bushing adapt- er 44 must be inserted into the guide plate 9 first. Place the guide bushing adapter 44 from above onto the guide plate 9 and tighten it firmly with the 2 fastening screws

45. Pay attention that the release lever for the guide bushing
