Take the bar and chain off for winter storage

For winter storage, remove the bar and chain and store them separately — don’t leave the whole assembly bolted on the saw.

The reason is moisture and sawdust. When a chainsaw sits for months, whatever is trapped in the bar groove and around the drive links is what rusts first. Sawdust acts like a sponge, and cold garage air supplies the rest. You can’t clean that area properly with the bar bolted on.

After removing, clean the bar — especially the groove and oil ports — wipe it down with oil, and hang it. Clean the chain, coat it well in bar oil, and stash it in a bag or sealed container. That gets the metal oiled and kept away from trapped grit.

Now, if you’re talking a month or so between uses, don’t overthink it. Just empty the tank, run it dry, and loosen the chain tension. But three months of winter? Take it apart. It’s a twenty-minute job, and spring-you will be glad the chain isn’t a rusted mess.

Half the rust you’ll ever see on a chainsaw starts in winter, so give that bar and chain a clean, oily bed.
