Chainsaw question

Post by Hovannes »

My Stihl MS250 is a great little saw and has seen a heck of a lot of use over the past couple of years. I keep the chain sharp and have had it professionally cleaned once, after felling a few palm trees because of the acid. The last time I had her out was after a windstorm downed a huge tree which engulfed a neighbor's house and garage. Some of the springy limbs even pinched the bar a couple of times, but I was able to push up the offending limbs and continue the job.
Of course the chain needed sharpening afterwards and I noticed that the teeth looked pretty hammered this time, but I was still able to sharpen them.
My question is, when should I consider putting on a new chain and how will I know if the bar needs replacing? I've already flipped the bar a few times and the paint is worn off so I don't know is the bar is upside down or not.

I don't want to spoil her, I just want to be safe.

This article says that a chain is only good for three to five sharpening.

WHEN TO REPLACE A CHAINSAW CHAIN: HOW TO TELL WHEN IT’S WORN OUT

At some point, the teeth are pretty much shot. After a few teeth break off, it's time to get a safer chain.

As far as the bar goes: If it's straight, no visible nicks, the new chain runs around the track, and she cuts straight -- I'd keep using it. But what do I know?

Yeah, what Del said. I have the same or similar Stihl saw, what is referred to as a "Farm Boss", but I don't recall the number. My neighbor borrowed it last week to cut down a large pine tree, and still has it, btw. I bought the saw in 2008, or perhaps 2007, so it's seen some use, multiple chains, and at least a couple of different bars. The key, IMO, is to use lots of bar and chain oil; good quality oil with plenty of tackifier.
