No, it's not normal for storage. The oil pump is likely priming or the saw was stored incorrectly.
- First, confirm the leak source. Clean the saw thoroughly and place it on a piece of cardboard.
- Store the saw with the guide bar and chain removed. Wipe the bar pad and sprocket area dry.
- Store it in a dry place with the oil tank cap tightened securely and the guide bar facing upward.
- If it leaks from the oil tank cap, check the O-ring seal for damage.
IF THAT DIDN'T WORK: The automatic chain oiling system may have a faulty pump or seal. A small amount of seepage after use is possible as the pump relieves pressure, but a constant leak indicates a service issue.
HEADS UP: Always use the correct bar and chain oil, not waste oil. Using the wrong oil can damage the oil pump and cause leaks.
