The declared vibration emission value has been measured in accordance with the standard test method and may be used for comparing one tool with another. The declared vibration emission value may also be used in a preliminary assessment of exposure. • The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Check tightness of screws carefully before operation. In cold weather or when the tool has not been used for a long time, let the tool warm up for a while by operating it under no load. This will loosen up the lubrication. Without proper warm-up, hammering operation is difficult. Always be sure you have a firm footing.
Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life. The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions: • Overloaded: The tool is operated in a manner that causes it to draw an abnormally high current. In this situation, release the trigger switch on the tool and stop the application that caused the tool to become overloaded.
When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled. • • • Selecting the action mode Rotation with hammering CAUTION: Always check the direction of rotation before operation. Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool. When not operating the tool, always set the reversing switch lever to the neutral position. 1. Rotation with hammering 2. Lock button 3.
