Do I need to drain the oil from the chainsaw when it's not in use; such as during the winter months? Or is it ok to leave it in? I notice a small amount of leakage, but not enough to make me worried. I just don't want to ruin the internals by leaving oil in there unnecessarily.
It is not necessary to remove the chain oil during storage.
However, it is normal for the oil to seep from the saw when it is not in use.
To prevent seepage, empty the oil tank, and then run the saw for one minute.
When storing the tool for a long period of time, be sure that the chain is
lightly lubricated; this will help to prevent rust on the chain and bar
sprocket. We hope this helps!
