It may be used for a preliminary assessment of exposure. 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 insertion tools or is poorly maintained, the vibration emission may differ. This may significantly increase 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 period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work pat- terns. Assembly Before any work on the machine itself, pull the mains plug. Auxiliary Handle Operate your machine only with the auxiliary handle 12. Changing the position of the auxiliary handle (see figure A) The auxiliary handle 12 can be set to any position for a secure and low-fatigue working posture. – Turn the bottom part of the auxiliary handle 12 in counter- clockwise direction and swivel the auxiliary handle 12 to the desired position. Then retighten the bottom part of the auxiliary handle 12 by turning in clockwise direction. Pay attention that the clamping band of the auxiliary handle is positioned in the groove on the housing as intended for. Adjusting the Drilling Depth (see figure B) The required drilling depth X can be set with the depth stop

– Press the button for the depth stop adjustment 10 and in- sert the depth stop into the auxiliary handle 12. The knurled surface of the depth stop 11 must face down- ward. – Insert the SDS-plus drilling tool to the stop into the SDS- plus tool holder 1. Otherwise, the movability of the SDS- plus drilling tool can lead to incorrect adjustment of the drilling depth. – Pull out the depth stop until the distance between the tip of the drill bit and the tip of the depth stop corresponds with the desired drilling depth X. Selecting Drill Chucks and Tools For hammer drilling and chiselling, SDS-plus tools are re- quired that are inserted in the SDS-plus drill chuck. For drilling without impact in wood, metal, ceramic and plas- tic as well as for screwdriving, tools without SDS-plus are used (e.g., drill bits with cylindrical shank). For these tools, a keyless chuck or a key type drill chuck are required. Changing the Key Type Drill Chuck To work with tools without SDS-plus (e.g., drills with cylindri- cal shank), a suitable drill chuck must be mounted (key type drill chuck or keyless chuck, accessories). Mounting the Key Type Drill Chuck (see figure C) – Screw the SDS-plus adapter shank 15 into a key type drill chuck 14. Secure the key type drill chuck 14 with the se- curing screw 13. Please observe that the securing screw has a left-hand thread. Inserting the Key Type Drill Chuck (see figure C) – Clean the shank end of the adapter shank and apply a light coat of grease. – Insert the key type drill chuck with the adapter shank into the tool holder with a turning motion until it automatically locks. – Check the locking effect by pulling the key type drill chuck. Removing the Key Type Drill Chuck – Push the locking sleeve 3 toward the rear and pull out the key type drill chuck 14. Changing the Tool The dust protection cap 2 largely prevents the entry of drilling dust into the tool holder during operation. When inserting the tool, take care that the dust protection cap 2 is not damaged. A damaged dust protection cap should be changed im- mediately. We recommend having this carried out by an after-sales service. Inserting SDS-plus Drilling Tools (see figure D) The SDS-plus drill chuck allows for simple and convenient changing of drilling tools without the use of additional tools. – Clean and lightly grease the shank end of the tool. – Insert the tool in a twisting manner into the tool holder until it latches itself. – Check the latching by pulling the tool. As a requirement of the system, the SDS-plus drilling tool can move freely. This causes a certain radial run-out at no-load, which has no effect on the accuracy of the drill hole, as the drill bit centres itself upon drilling. Removing SDS-plus Drilling Tools (see figure E) – Push back the locking sleeve 3 and remove the tool. Inserting Drilling Tools without SDS-plus Note: Do not use tools without SDS-plus for hammer drilling or chiselling! Tools without SDS-plus and their drill chucks are damaged by hammer drilling or chiselling. – Insert a key type drill chuck 14 (see “Changing the Key Type Drill Chuck”, page 14). – Open the key type drill chuck 14 by turning until the tool can be inserted. Insert the tool. – Insert the chuck key into the corresponding holes of the key type drill chuck 14 and clamp the tool uniformly. – Turn the mode selector switch 9 to the “drilling” position.

Dust Extraction with the Dust Extraction Attach- ment (Accessory) 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 car- cinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials con- taining asbestos may only be worked by specialists. – As far as possible, use a dust extraction system suitable 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. Prevent dust accumulation at the workplace. Dust can easily ignite. Mounting the Dust Extraction Attachment (see figure F) For dust extraction, the dust extraction attachment (accesso- ry) is required. When drilling, the dust extraction attachment retracts so that the attachment head is always close to the surface at the drill hole. – Press the button for depth stop adjustment 10 and remove the depth stop 11. Press button 10 again and insert the dust extraction attachment into the auxiliary handle 12 from the front. – Connect an extraction hose (diameter 19 mm, accessory) to the extraction sleeve 16 of the dust extraction attach- ment. 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. Adjusting the Drilling Depth on the Dust Extraction At- tachment (see figure G) The required drilling depth X can also be adjusted when the dust extraction attachment is mounted. – Insert the SDS-plus drilling tool to the stop into the SDS- plus tool holder 1. Otherwise, the movability of the SDS- plus drilling tool can lead to incorrect adjustment of the drilling depth. – Loosen the wing bolt 20 on the dust extraction attach- ment. – Without switching the power tool on, apply it firmly to the drilling location. The SDS-plus drilling tool must face against the surface. – Position the the guide pipe 21 of the dust extraction at- tachment in its holding fixture in such a manner that the head of the dust extraction attachment faces against the surface to be drilled. Do not slide the guide pipe 21 further over the telescopic pipe 19 of the dust extraction attach- ment than required, so that as much as possible of the scale 19 on the telescopic pipe remains visible. – Retighten the wing bolt 20 again. Loosen the clamping screw 17 on the depth stop of the dust extraction attach- ment. – Move the depth stop 18 on the telescopic pipe 19 in such a manner that the clearance X shown in the figure corre- sponds with the required drilling depth. – Tighten the clamping screw 17 in this position. Operation Starting Operation 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. Setting the operating mode The operating mode of the power tool is selected with the mode selector switch 9. Note: Change the operating mode only when the machine is switched off! Otherwise, the machine can be damaged. – To change the operating mode, push the release button 8 and turn the mode selector switch 9 to the requested posi- tion until it can be heard to latch. Reversing the rotational direction The rotational direction switch 4 is used to reverse the rota- tional direction of the machine. However, this is not possible with the On/Off switch 6 actuated. Right rotation: Turn the selector switch for drilling/ hammer drilling 4 on both sides to the stop in the position
