3.2 Attaching and Removing Accessories (SDS Plus Chuck System)

Figure 3.1: Inserting an SDS Plus Drill Bit
- To attach a drill bit or chisel: Clean the shank of the accessory. Pull back the chuck collar, insert the accessory into the chuck as far as it will go, then release the collar. Pull on the accessory to ensure it is securely locked. The SDS Plus system allows for slight axial movement of the bit, which is normal for hammer action.
- To remove a drill bit or chisel: Pull back the chuck collar firmly and pull the accessory out of the chuck.
3.3 Adjusting the Auxiliary Handle
The 360° rotary auxiliary handle can be adjusted to any position for optimal comfort and control. Loosen the handle by twisting it counter-clockwise, adjust to the desired angle, and then tighten by twisting clockwise until secure.
4. Operating Instructions
4.1 Selecting Operating Mode (4-in-1 Function Adjust Knob)

Figure 4.1: 4-in-1 Function Selection
Rotate the 4-in-1 function adjust knob to select the desired operating mode:
- Drilling (Rotation Only): For drilling in wood, metal, or plastic without hammer action.
- Hammer Drilling (Rotation with Hammering): For drilling in concrete, masonry, and stone.
- Chiseling (Hammering Only): For light chiseling, chipping, or demolition work.
- Chisel Direction Adjusting (Vario-Lock): Allows you to rotate and lock the chisel into various positions for optimal working angles.
4.2 Starting and Stopping the Tool
- To start the tool, press the variable speed reversing trigger. The speed increases as you press the trigger further.
