Worn out saw?

[Chippy]

Dont know much about petrol saws so looking for a bit of help.

 

Was helping a mates mate dismantle a large beech, he was using a stihl saw, I dont know which model, but think it was a 14" bar if this helps.

 

Saw would not cut at all well so chain was sharpened and it cut like it should do on sub 3" stuff.

 

When he started to cut larger limbs the saw really struggled to cut, on cutting the trunk it looked as though the saw was "stalling" the revs were there but dying down and the chain at times stopped with the engine still running, he had to lift of from the cut to restart the chain.

 

I only have an electric saw but to be honest mine could have done 3 times the work of his.

 

Any help will be much appreciated, or is it just knackered.

Sounds to me like a new clutch is in order. Very cheap and easy.

Cheers that's what I thought, but did'nt want to show my ignorance if it did'nt have one.

Just seen a youtube vid on how to do it, like you say easy to to do.

 

Thanks Alec

Did you have any wedges in the cut ? If the chain was getting trapped in the cut it would jam the chain.

Consider also the sharpening, if its not done properly it will cut smaller diameter but will jam in a deeper cut

 

Consider also the guide bar, if its not straight it will jam in a deeper cut

Clean the air filter and a properly sharpened chain would be the first things is look at.

Yes, also wear to the guide rails/burrs etc can have a big impact on how the saw cuts.

I would be surprised if it is a worn clutch.

 

Also consider it could be an MS180 which would really could struggle buried deep in hard wood particularly if the chain and bar are not spot on.

If the clutch was slipping, the revs would increase and the cha[n would stall in the cut. This simply sounds like you are using a saw that hasnt enough power or it is down on compression.

 

If you are using a ms181 or similar, they will struggle in anything bar 1-8inch cuts!

I agree with what has been said regarding the bar/chain etc. sometimes when I haven't sharpened the chain right it will dig down as you say (my ms181). Even tilting the saw to the left/right to find a decent biting point.

I know it's only a little saw but when it's on point I've took it to ash/beech bigger than the bar (14inch) and even though it requires a little patience it sometimes does surprise.
