Installation Guide

1. Prepare the Tool: Turn off and unplug the Dremel multi‑tool. Remove any existing accessory from the spindle.
2. Align the Mandrel: Hold the mandrel by its body, aligning the shank with the tool’s spindle opening.
3. Screw In: Rotate the mandrel clockwise until it is fully seated. The design ensures a tight fit without the need for additional fasteners.
4. Attach the Wheel or Disc: Place the polishing wheel or cut‑off disc onto the mandrel’s mounting surface, then secure it according to the accessory’s instructions (usually by tightening a set screw).
5. Test Run: Reconnect the tool and perform a low‑speed test to confirm that the accessory is firmly attached and operating smoothly.

Maintenance Tips

• Inspect mandrels regularly for signs of wear or damage. Replace any that show cracks, dents, or excessive burrs.
• Keep the shank area clean from dust and debris to maintain a secure fit with the spindle.
• Avoid using the mandrel with accessories that exceed the recommended torque specifications; this protects both the mandrel and the tool’s motor.
