5. Features and Controls
5.1 Motor and Power
The tool is equipped with a 13 Amp (1500W) motor designed for heavy-duty applications on concrete, masonry, and metal.
5.2 Function Mode Selector
The tool has three operating modes, selected via a double switch button for increased durability:
- Hammer Only (Chiseling-Only): Provides a hammering action without rotation. Use this mode for demolition, chiseling, or breaking tasks with the flat or point chisel.
- Hammer Drill (Hammering and Rotation): Combines hammering and rotation. This is the primary mode for drilling into concrete, brick, or stone.
- Drill Only (Rotation Only): Provides rotation only, without hammering. Use this mode for drilling into wood, metal, or other materials that do not require impact.
5.3 Ergonomic Design
- Vibration Control: Reduces user fatigue by minimizing transmitted vibration.
- 360-Degree Adjustable Auxiliary Handle: A rubber-coated side handle that can be rotated and locked into various positions for optimal control and comfort.
- Heat Dissipation System: Designed to prevent motor overheating during extended use.
- Double Anti-Dust Bottom Structure: Helps prevent dust and debris from entering the tool's internal mechanism, extending its service life.
5.4 Chuck System
The tool uses an SDS-Plus chuck system. This allows for quick and secure bit changes without the need for a chuck key. To insert a bit, push it into the chuck until it clicks. To remove, pull the chuck sleeve back and pull the bit out.
