How should I store a chainsaw for the winter?

Drain the fuel tank and run the engine until it stalls to clear the carb bowl and lines—ethanol gas turns to varnish in weeks and clogs carburetors. Clean the bar groove and oil holes, loosen the chain, and store it hanging or on its side. For storage longer than a season, pull the spark plug, add fogging oil, and pull the cord to coat the cylinder walls.
