Maintenance Tips
-
Clean After Use: Wipe dust and debris from the tool body, vents, and interchangeable chuck to prevent buildup and help cooling and performance in heavy jobs.
-
Lubricate Bit Shanks: Apply SDS‑PLUS bit grease to the chuck and bit shanks periodically to ease insertion and reduce wear on moving parts.
-
Inspect Fasteners: Before operation, check the side handle, chuck, and any attachments for tightness to ensure safe handling and accurate drilling.
-
Dust Extraction Care: If using with a dust extractor (sold separately), empty and clean filters regularly for consistent airflow and OSHA‑compliant dust control.
-
Battery Best Practices: Charge the included 40V XGT battery before it’s fully drained and store in a cool, dry place to maximize lifespan.
-
Rest Between Heavy Drills: After prolonged or high‑load drilling, power down and let the tool cool before continuing to prevent overheating.
-
Authorized Service Only: For internal wear or repairs, use Makita authorized service centers and genuine parts to maintain performance and warranty compliance.
