1. Handpiece Rotating Instead of Bur / Handpiece Rotating with Bur
Step 1: Disconnect handpiece from motor; inspect for physical damage.
Step 2: Ensure bur is securely locked.
Step 3: Manually rotate the bur; it should turn smoothly.
Step 4: Verify if bur is clinical or laboratory type. Recommend clinical bur if laboratory bur causes rotation issues.
Step 5: Oil the handpiece from the bottom using provided nozzle and retest.
Step 6: Arrange RVP if unresolved. Provide approximate repair charges if out-of-warranty (OOW).
2. Abnormal Noise / Vibration / Intermittent Stopping
Step 1: Disconnect from motor, check for physical damage. Replace bent/damaged bur.
Step 2: Oil handpiece from bottom with provided nozzle.
Step 3: Test with another handpiece on same motor; refer to motor troubleshooting if the issue persists.
Step 4: Suspected bearing damage; arrange RVP and refer to cost sheet for OOW.
3. Dummy Bur Not Removable
Step 1: Disconnect from motor, check for physical damage.
Step 2: Unlock bur by rotating locking part anti-clockwise.
Step 3: Arrange RVP if still stuck.
Step 1: Disconnect and inspect handpiece for visible damage.

Step 4: Ensure shaft is fully unlocked (refer instructional video).
Step 5: Oil from bur insertion point using cone nozzle and retest.
Step 6: Suspected shaft damage; arrange RVP and refer to cost sheet for OOW.
7. Handpiece Sticking or Jamming in Motor
