I have this pretty awesome light duty saw. I have two recurring problems: 1: the chain gets loose. As in 1" gap. 2: (unrelated to 1) cuts crooked, intermittently, Always toward the motor. I put three strokes per tooth with my file when I need gas. Am I doing something wrong? the bar is as tight as a frogs ass, despite the loose chain. I always leave a third of the guide tooth in the bar when I tighten the chain. I would ask the guy who gave me the saw, but I don't want to sound like a bitching, complaining, friend of his BIL. |

Tighten the chain when it gets loose. There is a screw that you turn with the bar nuts loose that pushes the bar forward. turn it until the guide prongs on the chain can't be completely out of the bar with moderate pulling force. the cutting crooked is from improper sharpening. the angle and elevation of the file is more important than the number of strokes.
Make sure that you have a high cling bar oil in the resivoir and don't use motor oil. |

Get a chain file guide from a saw shop. Make sure both sides of the chain are even or you will be cutting circles. The loosening issue could be related to not enough bar and chain oil getting distributed. That heats everything up and wears out the bar (chain also).
I have been an arborist for 20 years and never used a dremel or any gadget to sharpen a chain. A good round file is far better and wastes less chain.
