shock the operator. When working with the power tool, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more securely with both hands. Secure the workpiece. A workpiece clamped with clamping devices or in a vise is held more securely than by hand. Do not work materials containing asbestos. Asbestos is considered carcinogenic. Take protective measures when dust can develop during working that is harmful to one s health, combustible or explosive. Example: Some dusts are regarded as carcinogenic. Wear a dust mask and work with dust/chip extraction whenever possible. Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode. Always wait until the power tool has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool. Do not use the power tool with a damaged cord. Do not touch the damaged cord and pull the plug from the outlet when the cord is damaged while working. Damaged cords increase the risk of an electric shock. ASSEMBLY Page 4 of 13

Before any work on the rotary hammer itself, pull the main plug. Selecting Drill Chucks and Tools For hammer drilling and chiseling, SDS-plus tools are required that are inserted in the SDS-plus drill chuck. For drilling without impact in wood, metal, ceramic and plastic as well as for screw driving and thread cutting, tools without SDS-plus are used (e.g., drills with cylindrical shank). For these tools, a keyless chuck or a key type drill chuck are required. Inserting the Key Type Drill Chuck (see figure A) Clean the shank end of the adapter shank and apply a light coat of grease. Insert the drill chuck (3) 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 (5) toward the rear and pull out the key type drill chuck (14). Removing the Quick Change Chuck (see figure B) Pull the lock ring for the quick change chuck (5) toward the rear, hold it in this position and pull off the SDS-plus quick change chuck (2) or the quick change keyless chuck 1 toward the front. After removing, protect the replacement chuck against contamination. Changing the Tool The dust protection cap (4) largely prevents the entry of drilling dust into the tool holder during operation. When inserting the tool, take care that the dust protection cap (4) is not damaged. A damaged dust protection cap should be changed immediately. We recommend having this carried out by an authorized service center. Inserting SDS-plus Drilling Tools (3) (see figure C) 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. Pull back locking sleeve (5), the drill bit (3) into the tool. Check the latching by pulling the tool. Removing SDS-plus Drilling Tools (see figure D) Push back the locking sleeve (5) and remove the tool. Inserting Drilling Tools without SDS-plus construction Note: Do not use tools without SDS-plus construction for hammer drilling or chiseling! Tools without SDS-plus construction and their drill chucks are damaged by hammer drilling or chiseling. Insert a key type drill chuck (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 tightly. Turn the mode selector switch (10) to the Drilling position. Page 7 of 13
AUXILIARY HANDLE Operate your power tool only with the auxiliary handle (12). Rotating the Auxiliary Handle (see figure E) 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 F) The required drilling depth X can be set with the depth stop (16). Press the button for the depth stop adjustment (11) and insert the depth stop into the auxiliary handle (12). The knurled surface of the depth stop (16) must face downward. Insert the SDS-plus drilling tool to the stop into the SDS-plus tool holder (3). 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 correspond with the desired drilling depth X. Removing Drilling Tools without SDS-plus Turn the sleeve of the key type drill chuck (14) with the drill chuck key in a counterclockwise direction until the drilling tool can be removed. Inserting Drilling Tools without SDS-plus (see figure G) Note: Do not use tools without SDS-plus for hammer drilling or chiseling! Tools without SDS-plus and their drill chucks are damaged by hammer drilling or chiseling. Insert the quick change keyless chuck 1. Firmly hold the retaining ring (18) of the quick change chuck. Open the tool holder by turning the front sleeve (17) until the tool can be inserted. Tightly hold the retaining ring (18) and firmly turn the front sleeve (17) in the direction of the arrow until a distinct latching noise can be heard. Check the tight seating by pulling the tool. Note: If the tool holder was opened to the stop, then the latching noise possibly may be heard while closing the tool holder and the tool holder will not close. In this case, turn the front sleeve (17) once in the opposite direction of the arrow. Afterwards, the tool holder can be closed (tightened) again. Turn the mode selector switch (10) to the Drilling position. Removing Drilling Tools without SDS-plus (see figure H) Firmly hold the retaining ring (18) of the quick change chuck.
