What is the break-in time for a new chain?

• A. 1-2 minutes
• B. 3-4 minutes
• C. 4-5 minutes
• D. 2-3 minutes

Answer: (D)

The idea behind break-in time is to let the new chain’s drive links and side plates seat properly against the bar so everything tracks smoothly and wears evenly. A short, controlled period of light cutting lets the chain rub and settle into the bar rails without overheating or glazing the teeth. About two to three minutes of light cutting in clean wood, with steady throttle, gentle feed, and with the chain well-lubricated and tensioned, is usually enough for the parts to settle. Avoid heavy cuts or high loads during this time, and maintain proper oiling and tension. If you go too short, the chain may not seat properly and wear unevenly; too long a break-in can overheat the chain and bar.
