- Attaching Side Handle: Slide the side handle onto the collar behind the chuck. Rotate the handle to the desired position and tighten the grip to secure it.
- Inserting Depth Gauge: Insert the plain round rod of the depth gauge into the designated hole on the side handle. Adjust to the required depth and tighten the side handle grip to lock it in place.

5. Operating Instructions
Drilling Modes:
- Hammer Drilling Mode (Hammer Icon): Select this mode for drilling into concrete, masonry, and stone. The tool provides both rotation and hammering action for efficient material removal.
- Rotary Drilling Mode (Drill Bit Icon): Use this mode for drilling into wood, metal, and plastic. Only rotation is provided, without hammering action.
Drilling Techniques:
- Starting a Hole: Begin drilling at a low speed to prevent the bit from wandering. Once the hole is started, increase speed as needed.
- Applying Pressure: Apply steady, firm pressure in line with the drill bit. Avoid excessive force, which can overheat the tool or bit.
- Clearing Debris: Periodically withdraw the drill bit from the hole to clear dust and debris, especially when drilling deep holes.
