How do I swap a chainsaw chain without damaging it?

Yes, you can do it without bending drive links or gouging the bar — just don’t rush. First, make sure the chain’s pitch and gauge match your bar; if the numbers don’t line up, stop. Loosen the tension adjuster all the way, then work from the top of the bar down, seating drive links by hand. If it doesn’t slide in easily, you have the wrong chain or the tension is too tight — forcing it will bend drive links and ruin the chain.
