5.2 Forward/Reverse Switch

The forward/reverse switch is located above the trigger. Push it to the left for forward rotation (drilling) and to the right for reverse rotation (removing screws or freeing a stuck bit).

5.3 2-in-1 Function Switch (Drill Mode / Hammer Drill Mode)

Select the appropriate mode using the gray dual-mode switch on top of the drill:

• Drill Mode: For drilling into softer materials like wood, metal, and plastic.
• Hammer Drill Mode: For drilling into harder materials such as lightweight concrete and brickwork. This mode combines rotation with a hammering action.

Figure 4: The 2-in-1 function switch allows selection between drill and hammer drill modes.
