2. Setup
2.1 Battery Installation and Removal
This tool operates with an Erbauer EXT 18V battery (not included). Ensure the battery is fully charged before use.
- To Install: Align the battery with the receptacle at the base of the drill handle. Slide the battery into place until it clicks securely.
- To Remove: Press the battery release button (usually located on the battery pack) and slide the battery out of the tool.
2.2 Attaching the Auxiliary Handle
The auxiliary handle provides additional control and safety, especially during high-torque applications or hammer drilling.
- Loosen the auxiliary handle by rotating it counter-clockwise.
- Slide the handle over the chuck and onto the front of the drill body.
- Adjust the handle to your desired position for optimal grip and control.
- Tighten the handle by rotating it clockwise until it is securely fastened.
2.3 Chuck Operation (Installing/Removing Drill Bits)
The drill features a 13mm self-tightening metal chuck for quick and secure bit changes.
- To Open the Chuck: Hold the rear part of the chuck firmly and rotate the front part counter-clockwise until the jaws are wide enough to accept the bit.
- To Install a Bit: Insert the drill bit or accessory fully into the chuck jaws.
- To Close and Tighten the Chuck: Hold the rear part of the chuck firmly and rotate the front part clockwise until the bit is securely gripped. The self-tightening mechanism will ensure a firm hold.
- To Remove a Bit: Reverse the tightening process by rotating the front part of the chuck counter-clockwise.
3. Operating Instructions
3.1 Mode Selection
The Erbauer ECDT18-Li-2 offers three operating modes: Screwing, Drilling, and Hammer Drilling. Select the appropriate mode using the mode selector ring located behind the chuck.
- Screwing Mode (Screw Icon): For driving and removing screws. Use with appropriate torque settings.
- Drilling Mode (Drill Bit Icon): For drilling into wood, metal, and plastics.
- Hammer Drilling Mode (Hammer Icon): For drilling into masonry and concrete. Use with masonry drill bits.
3.2 Torque Settings
The drill features 24 torque settings, allowing you to adjust the amount of rotational force applied. This prevents over-tightening screws and damaging materials. Rotate the torque adjustment ring (located behind the mode selector) to select the desired setting. Higher numbers indicate greater torque.
- Use lower torque settings for smaller screws or softer materials.
- Use higher torque settings for larger screws or harder materials.
- For drilling, set the ring to the drill icon (usually the highest setting) to bypass the clutch and deliver maximum power.
3.3 Variable Speed Trigger and Direction Control
- Variable Speed Trigger: The trigger controls the speed of the drill. Pressing the trigger further increases the speed.
- Forward/Reverse Selector: A switch located above the trigger allows you to select forward (clockwise) or reverse (counter-clockwise) rotation. Ensure the switch is in the central position to lock the trigger and prevent accidental starting.
3.4 LED Work Light
The integrated LED light illuminates the work area when the trigger is pressed, improving visibility in dimly lit conditions.
3.5 Belt Clip
The convenient belt clip allows for easy transport and temporary storage of the tool when not in active use. Attach it to your belt or waistband for quick access.
4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your tool.
4.1 Cleaning
