When do you operate the chain without oil?

• A. Always
• B. Only when the reservoir is full
• C. Never
• D. Only when it is clean

Answer: (C)

Lubrication of the chain and bar is essential for safe and effective operation. You never operate the chain without oil because oil reduces friction, carries heat away, and smooths the motion of the chain over the bar. Without oil, metal-to-metal contact increases dramatically, causing rapid wear, overheating, dulling of the chain, and potential damage to the bar and drive sprocket. This also raises the risk of dangerous kickback and other accidents. So the correct stance is to always ensure the bar-and-chain oil reservoir is full and oil is reaching the chain before and during use. The other ideas imply running without lubrication under certain conditions, but none of that is acceptable practice.
