What I see in this video as a new Stihl chainsaw owner is that the old chainsaws were way better because they lasted a lot longer and the parts were more adjustable.
Another reason I found out the hard way was when cutting multiple small branches like on a cedar tree to get a clear path to the trunk, if you go to fast these small branches can knock the chain around and dislodge it.
I'm just getting into chainsaw milling. I have a Stihl MS660 and a brand new 30" bar and ripping chain from Granberg. I get there's a break in period but my chain is practically falling off after every cut, I keep tightening it hoping that it was just the chain breaking in still. I'm gonna take it to the repair shop next week because I'm guessing it's the tensioner or the sprocket. I'm not an expert but I've put old/used chains on bars and haven't had that problem
Yes I have a question I have a narrow kerf husqvarna 20 inch 450 rancher .325 is it possible to change to a regular kerf 3/8 bar and chain ? Great video by the way...
I have the same thing. It's my first chain saw and I have a hard time keeping the tension just right. Sorry I don't know the answer to your question though.
What does a worn druve spoket look like. My old second hand stihl 009 has a groove in the center if the drive sproket. I cannot use the tenioner to remove the slack. Its fully forward and I could probably remove 1 link to get it to fit regular-like
After yiu tension the chain using the tensioner dont you torque down the nuts locking the bar in place? How could the tensioner cause it to loosen at this point?
I have slipped a few chains cutting off heavy stumps. I was cutting a five foot diameter hickory stump a few years ago. It did not come off the bar to the point it hit the chain catcher, but it did slip off. I caught it in time and reinstalled it, correctly, and tensioned it properly. It was on my MS 660 with a 36 inch bar. I finished cutting through the stump with the 660 and finished up the stump with my MS 360 with a 20 inch bar. It took two of us to push the cut stump off its base. It must have weighed 500#. Just be careful cutting off big heavy stumps with long bars because the can cause the chain to come off a bar. I think the weight and heat generated in the chain are the cause. It was so hot that day that gas boiled in the tanks of my chainsaws when I refilled them with gas.
Oh absolutely, this is a great point. Longer bars would be more susceptible to this problem. That should have made the list or at least gotten a mention.
@@HipaParts bow saws are the worst. I used to slip the chain from my Poulan 3700 CV all the time. It also had no chain tensioner, so I had to loosen the nuts, tighten the bow with a screwdriver for a lever and then tighten the nuts. It had lockwashers but these would loosen over time. If you were diligent, you could tell when it was about to come off the bow. Same with a bar, but you have to be diligent and not in a hurry.
I've run my brand new $500+ Stihl chainsaw for ~30 minutes and the chain flies off the bar and it's just not useable anymore. I look at what's in this video and see bars and chainsaws that have run a thousand hours or more and still work.
@@boomer1049 I think all you can do is buy new sprockets and refit the thing with new sprockets AND a new chain. Imagine you're halfway done cutting a tree and your chain flies off and now you have a dangerous tree that can fall any second....not fun.
