#### Maintenance

- **Collet:** Clean and inspect regularly; replace if worn or damaged
- **Spoilboard:** 3/4" board - monitor thickness as holes and resurfacing accumulate; resurface when uneven
- **Dust collection / dust shoe:** **TBD** - coming soon; add maintenance steps when installed
- **Linear rails:** Wipe down per Onefinity manual
- Report problems on Slack or to a shop officer
