Functions of Bar Oil
- Friction & Wear Reduction: It forms a protective layer to prevent metal-on-metal contact, extending the life of both the bar and the chain.
- Heat Dissipation: It helps keep the cutting assembly cool; without it, friction can cause the metal to burn, turn blue, or even warp.
- Cleaning: The oil helps carry away sawdust and debris, preventing the chain from getting gummed up, especially in sappy wood.
- Corrosion Protection: It protects components from rust, which is vital when working in damp environments.
