Maintenance
Regular maintenance extends the life of your spindle assembly and ensures optimal performance.
- Lubrication: This spindle assembly features a grease fitting. Periodically apply a small amount of multi-purpose grease using a grease gun to ensure proper bearing lubrication. Frequency depends on usage, but typically every 25 hours of operation or annually.
