5.1 Selecting Operating Mode
Rotate the mode selector switch to choose the appropriate function:
- Drilling Mode (Drill Bit Symbol): For drilling in wood (up to 40mm) and metal (up to 13mm). Use with the key chuck and standard drill bits.
- Hammer Drilling Mode (Drill Bit + Hammer Symbol): For drilling in concrete or brick (up to 26mm). Use with SDS Plus drill bits.
- Chiseling Mode (Hammer Symbol): For chiseling applications, such as breaking concrete or removing tiles. The accessory is fixed in position.
- Chiseling with Free Accessory Adjustment (Hammer + Rotating Arrow Symbol): Allows the chisel to rotate freely, useful for adjusting the angle when removing tiles or similar tasks.
5.2 Variable Speed Control
The trigger features variable speed control. Press the trigger lightly for lower speeds and press harder for higher speeds. This allows for precise control depending on the material and application.
5.3 Continuous Operation
For extended use, the tool can be set to continuous operation. Press the trigger and then engage the lock-on button (if present, typically on the handle). To disengage, press the trigger again.
