How to tell when the chain saw blades need replacement? I sharpen my own (and file the depth gauge) and as of now they are cutting just as good as new. However the blades are growing shorter and shorter. Is there a length to these that determines replacement?
Lots to learn about chain saws, bars, chain, but for now, the "blade" as you call it is probably what we are thinking as the "chain".
It has the cutters on it and separator links in between.
The bar is the part of the saw that the chain rides around on.
It's all ok, you have to learn so have at it. We all learned too.
If it's dull then the cutters need sharpening,
But as a rookie, do yourself a favor, bring the saw in to a local saw shop and ask some questions.
Buy a new chain, ask how to tension it properly and what to use for bar oil and saw fuel.
They should be able to help you out easily and maybe tell you about the current chain and even sharpen it for you.
It's good to have a couple chains for each saw.
