How to Use

Insert the 2.35mm shank into your rotary tool or handpiece collet and tighten securely.
Before powering on, set the speed governor to the minimum or zero position.
Power on and gradually increase speed. Do not exceed 10,000 RPM to prevent damage to the shank or shaft.
Avoid sudden jumps to high-speed operation after installation, as this may cause the rear axle to bend.
