If you’re using your saw for a chainsaw mill, it won’t be long before your saw needs attention. My Stihl MS460 was no longer providing oil to the bar and chain. I walk through diagnosing and repairing the problem and we’ll take a look at the parts of the saw so repairing yours will be less daunting. Most Stihl saws will have a very similar assembly but specifics on other brands will vary. However, they will all have similar parts and operate the same.
