The hammer is powered by a dual-spring unit that uses two springs with different tension strengths. For lighter tasks, one spring is used, while the second spring is activated for heavier jobs. This minimizes recoil and reduces vibrations.

Tightening Level 4: Maximum impact rate of 4,100 min-1. Ideal for tightening with maximum force and speed, for example when driving screws into base materials or tightening long screws.

Tightening Level 3: Maximum impact rate of 3,600 min-1. Suitable for tightening with less force and speed than in Max mode, allowing for easier control. Example: Driving screws into base materials or tightening screws.

Tightening Level 2: Maximum impact rate of 2,600 min-1. Optimal for tightening when a clean finish is required, such as when driving screws into finished boards and drywall.

Tightening Level 1: Maximum impact rate of 1,400 min-1. Used for tightening with less force to avoid breaking the screw threads. Example: Tightening wing screws or small screws like M6.

T-Mode: The tool drives a screw at high speed and stops shortly after the impact operation begins to prevent the screw from being tightened too firmly. Example: For driving self-tapping screws into a thin metal plate.
