Bearings are double steel-shielded for extra rigidity and to inhibit dust. A special high-performance, high temperature grease is used for maximum life.
Note: solvents should not be used to clean ball bearings. If a ball bearing becomes frozen (does not rotate freely) replace immediately.
WARNING: Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. For more information go to www.P65Warnings.ca.gov/wood.
