¶ Fixing a Loose Collet Lever
¶ Tools Required
- 1.5mm Allen key
- 2.5mm Allen key
¶ Procedure
¶ Step 1: Remove the Grub Screws
- Locate the grub screws securing the collet lever shaft.
- Using a 1.5mm Allen key, remove the front grub screw as shown in Figure 1.
- Similarly, remove the rear grub screw as indicated in Figure 2.
¶ Step 2: Remove the Collet Release Lever
- With the grub screws removed, lift the collet release lever upward and out of the collet lever shaft.
- Ensure that no debris or obstructions are present before proceeding to the next step.
¶ Step 3: Tighten the Shaft Securing Screw
- Looking from the left side, locate the central hole in the collet lever shaft.
- Inside this hole, identify the 2.5mm Allen screw that secures the shaft in place (Figure 3).
- Use a 2.5mm Allen key to tighten this screw, ensuring the shaft is firmly secured.
¶ Step 4: Reinstall the Collet Release Lever
- Position the collet release lever back onto the shaft.
- Insert and tighten the grub screws, ensuring they are properly seated in the small locating hole near the end of the shaft (Figure 4).
¶ Final Check
- Confirm that the collet lever moves freely without excessive play.
- Ensure all screws are securely fastened to prevent future loosening.
- Test the functionality before returning the machine to operation.
