Driftstilstande
The SFMCH900B features a mode selector switch (2) to choose between different operating functions:

Figure 8: The mode selector switch allows selection of drilling, hammer drilling, or chiseling functions.
1. Hammer Drilling Mode (Hammer and Drill Bit Icon)
This mode is for drilling in concrete, masonry, and brick. It combines rotary action with powerful hammer blows for fast drilling progress.

Figure 9: Demonstrating hammer drilling into a wall.
2. Drilling Mode (Drill Bit Icon)
This mode provides rotary action only, suitable for drilling in wood, metal, plastics, and ceramics. The impact mechanism is disengaged.
3. Chiseling Mode (Chisel Icon)
This mode provides hammer action only with a rotary stop, ideal for light chiseling work in plaster, tiles, or for removing small amounts of material. Ensure a chisel bit is installed.
