3. Bit Installation (SDS Plus Chuck):
   • Clean the shank of the SDS Plus bit.
   • Pull back the chuck collar and insert the bit into the chuck.
   • Release the chuck collar. The bit should click into place. Pull on the bit to ensure it is securely locked. A slight axial play is normal for SDS Plus systems.
4. Depth Rod Adjustment: Insert the depth rod into the hole on the side handle. Adjust the rod to the desired drilling depth and tighten the side handle grip to secure it.
5. Dust Extractor Connection (Optional): If using a compatible dust extractor (e.g., 2912-DE), connect it to the designated port on the tool as per the dust extractor's instructions.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your tool.

• Cleaning: Keep the tool's ventilation openings clear and free of debris. Use a soft brush or compressed air to clean dust and chips from the tool. Do not use water or chemical cleaning agents.
• Lubrication: The tool's internal components are factory lubricated and generally do not require additional lubrication. For SDS Plus chucks, apply a small amount of grease to the bit shank periodically to ensure smooth operation and prevent wear.
• Inspection: Regularly inspect the power cord (if applicable), battery pack, and tool housing for any damage. Check that all screws are tight.
