The guard on the KS 120 is not retracting correctly, what can be done to fix it?

To try and remmedy the non-retracting blade, follow these steps:
  1. Disconnect the power or remove the batteries. 
  2. Remove the blade (clockwise to loosen KS blade bolts)
  3. Inspect the inside guard cover for any debris which may be lodged preventing smooth operation.
  4. Reinstall blade, counter clockwise to tighten firmly if unable to remedy
  5. Take KS to an authorised repairer or drop off location https://www.festool.com.au/services/festool-warranty-agents.html https://www.festool.com.au/repairs-centre
