[. . . ] Total vibration (vector sum of three directions) is calculated in accordance with EN 60745: Drilling in metal: Vibration emission value ah, D = 3, 2 m / s2 Uncertainty K = 1, 5 m / s2 Hammer-action drilling in concrete: Vibration emission value ah, ID = 19, 313 m / s2 Uncertainty K = 1, 5 m / s2 Warning!The vibration level given in these instructions has been measured in accordance with a standardised measurement procedure specified in EN 60745 and can be used to compare devices. Different uses of the device give rise to different vibration levels and in many cases they may exceed the values given in these instructions. It is easy to underestimate the vibration load if the electrical power tool is used regularly in particular circumstances.

Store the device indoors in an enclosed, dry place where it cannot be reached by children. To avoid danger to life from electric shock: Frequently check the condition of the device, mains lead and plug. Always have any repairs carried out or replacement parts fitted at the service centre or by an electrical equipment repair specialist. A damaged device, mains lead or plug presents a serious danger to life from electric shock. J Have repairs carried out only by an electrician or your service centre. J Do not touch the mains lead if it becomes damaged or cut through while you are using the device. Pull the plug out of the mains socket immediately and have the device repaired by a suitably qualified person or at your service centre. J Do not operate the device if it is damp and do not use it in a damp environment. Devices marked with 230 V can also be operated at 220 V. Inserting a tool into the chuck Caution!Before starting any tasks on the hammer drill, make sure that it is switched off and the mains plug is out of the socket. The RÖHM quick-release drill chuck allows you to exchange drills or other tools without using a special key etc. Switching on and off Switch on intermittent operation mode: j Press the On / Off switch 3 . Switch off intermittent operation mode: j Release the On / Off switch 3 . Switch on constant operation mode: j ress the On / Off switch 3 , and keep it P pressed, then press the locking button 4 . Switch off constant operation mode: j Press the On / Off switch 3 and release it. Opening the chuck and inserting a tool j old the rear shell of the quick-release chuck 9 H and turn the front shell until the tool (e. g. Insert the tool. Tightening the chuck on to the tool j old the rear shell of the quick-release chuck 9 H and turn the front shell sharply until you hear a , , click ­ clack, clack, clack" sound (refer to Figure A). To release the lock again, just turn the front shell in the opposite direction. Infinitely adjustable speed setting To produce a slow speed, just press lightly on the On / Off switch 3 . This allows you to start up your operations smoothly and in a controlled manner. If you increase the pressure on the On / Off switch 3 , the speed will also increase.
