To fell a standing tree, it’s recommended that you use a bar longer than the diameter of a tree. To cut a tree that has already fallen, you can cut up to double the bar length minus a couple of inches by making two cuts, one from each available side of the tree. For example: If the bar is 16” you can cut a log up to 30” in diameter.

This chainsaw can take any kind of bar and chain oil, which is available in most hardware stores or stores that sell chainsaws.

With a saw designed to self-lubricate during operation, a little oil leakage is normal. To help minimize and prevent leakage, we recommend wiping down the tool after use and storing it horizontally when not in use.

All our traditional chainsaws include our patented auto-tension chain tightening system that prevents over-tightening for extended bar & chain life.
