5. Operating Instructions

5.1 Mode Selection

The WORX H3 Rotary Hammer offers three operating modes:

• Hammer Drilling Mode: For drilling into masonry and concrete. Select this mode using the mode selector switch on the side of the tool.

5.2 Variable Speed Control

The tool features a variable speed trigger. The speed of operation is controlled by the amount of pressure applied to the trigger. Light pressure results in lower speed, while increased pressure increases the speed. This allows for precise control during various tasks and helps conserve battery life.

5.3 Integrated LED Light

The integrated LED light illuminates the work area, providing better visibility in dimly lit spaces or corners. The light activates automatically when the trigger is pressed.
