Usage Instructions

1. Installing the Bur
   Insert a standard bur (shank diameter Φ1.595-Φ1.600 mm) into the handpiece chuck. Use the bur wrench to push it to the bottom and ensure it is properly seated. Before use, run the handpiece without a bur for 1-5 seconds to verify smooth operation.

2. Bur Selection
   Do not use bent, damaged, or non-concentric burs. Only use burs that comply with ISO standards (shank diameter Φ1.595-Φ1.600 mm).

3. Bur Removal and Installation

   • Removal: Align the bur wrench with the inner hole of the head cap and push vertically downward to release the bur.

   • Installation (bur with working end diameter >1.5 mm): Insert the bur shank into the shaft hole and push it firmly to the top position.

   • Installation (bur with working end diameter ≤1.5 mm): Follow the same procedure, ensuring the bur shank is fully inserted and seated.
