chirpy Posted June 20, 2010 Share Posted June 20, 2010 I have had a Stihl 260 for a few years but noticed that I cannot pull the chain by hand when checking the tension.Any ideas please. Link to comment Share on other sites More sharing options...
tonyv Posted June 20, 2010 Share Posted June 20, 2010 I would recommend you taking it to an appointed agent for a service. A chain-saw's not something you want to mess about with. Imagine the chain breaking. Link to comment Share on other sites More sharing options...
Gluestick Posted June 20, 2010 Share Posted June 20, 2010 The tension is too tight. Or the end cog on the blade has worn and is sticking: or the centrifugal clutch is not releasing. The blade could be twisted, slightly.Start by stripping out the blade and chain: then remove and check the centrifugal clutch.It is quite common for wood dust, chips etc to build up in the clutch mechanism and around the drive sprocket. This is not helped by the chain oil building up and it forms a nasty mucky mess.Strip it all down and wash out chain, blade, clutch and housing with petrol: thereafter check each bit as you reassemble.

DerekJ Posted June 20, 2010 Share Posted June 20, 2010 I agree with the above. Also have a look at the bar. You may find it is burred up. You can remove these with a gentle filing. I ended up replacing my bar with an Oregon one. Link to comment Share on other sites More sharing options...
f1steveuk Posted June 20, 2010 Share Posted June 20, 2010 All of the above, plus......I have just done a chain saw for a friend. He had been using the very tip of the bar,leaning on it quite hard, and had worn it to the bar had a reverse curve at the very end, this meant the the chain when adjusted correctly, still wouldn't turn., but it sounds like a tension problem to me, probably linked to a worn chain.

La Guerriere Posted June 21, 2010 Share Posted June 21, 2010 Sounds as though he had been carving with it .... Link to comment Share on other sites More sharing options...
f1steveuk Posted June 21, 2010 Share Posted June 21, 2010 I think he's learnt his lesson, new bar, new chain etc etc. I pointed out the little teeth that are for controling the cut by sticking them into the bark, and that they were at the opposite end to the one he was cutting with!!!

chirpy Posted June 24, 2010 Author Share Posted June 24, 2010 yes..Today I took off the cog which drives the chain as I noticed it had a little bit of one of the teeh very worn and replaced it with another one I had from my first purchase in france which had a very worn out engine .The chain now runs smoothly when I pull it by hand.I have not cut any wood with it as I am busy with an electric model cutting wood to length for the next awful winter.thanks for your help.

Jonzjob Posted June 24, 2010 Share Posted June 24, 2010 Don't forget to keep the chain oiled and check the level in the tank on yer electrifical, or you might just find that you can't move the chain by hand [6][6][B] Link to comment Share on other sites More sharing options...
