How to use

Fit the Makita attachment into the SDS‑MAX chuck of a compatible rotary hammer following the tool manufacturer’s guidance on insertion and locking. Ensure the rotary hammer is switched off and disconnected from power while fitting. Use appropriate drill bits and anchors with the attachment for the intended material. During operation, maintain steady feeding pressure and allow the hammering action to clear debris; pause periodically to withdraw and clear dust when drilling deep holes.

Usage recommendations

Use personal protective equipment including eye protection, hearing protection and dust mask when drilling. Verify compatibility with your specific SDS‑MAX rotary hammer model and select drill bits and anchors suitable for concrete or masonry. Avoid excessive lateral loads on the extension to prevent premature wear or damage.
