What is the proper sequence of actions when a chainsaw stalls under load?

• A. Increase throttle, clear obstruction, and re-enter the cut.
• B. Release throttle, clear obstruction if safe, and restart with proper technique.
• C. Shut the engine off and walk away from the saw.
• D. Restart the engine while the bar remains under load.

Answer: (B)

Recovering from a chainsaw stall under load requires a calm, controlled sequence that reduces risk and brings the tool back under control. Start by releasing the throttle to bring the engine to idle, which slows the chain and reduces the load on the bar. If it’s safe to do so, clear the obstruction that caused the stall — but only with a safe stance and without placing your hands near the moving chain. After the obstruction is addressed, restart the saw using proper technique so you re-enter the cut with the bar clear and under control, maintaining a solid grip and correct stance. Increasing the throttle would keep the chain spinning and can worsen the stall. Shutting the engine off and walking away isn’t a proper recovery since it leaves you unable to resume the task safely. Restarting with the bar still under load creates a high risk of kickback or binding.
