Oil Boiling

[Bonvi]

Purchased a new MS 290 Farm Boss.Started it after many rope pulls the oil in the resovoir stared to boil and the chain was so hot I couldn't touch it with bare hands,it actually turned blue.The local dealer said not to run fuel higher than 89octane.
Help, have I damaged this saw for good.I drained the old fuel and replaced it with an 89 octane mix as recommended.

The chain getting hot and the oil boiling has nothing at all to do with the type of fuel you have used .

You must now find out why the chain is getting hot .
1/ Is the oil supply hole in the bar clear ?
2/ Was the chain too tight ? Is it really loose now ?
3/ Are you sure you have proper chain oil in the front tank ? Forgive the question , you haven't put fuel or two stroke oil in the front tank have you ?

There is proper bar oil that is used for the chain, it is a fairly thick oil.
Could be that #3 above is the problem.

Was the chain brake on?:confused3:

Are you cutting dry Hedge/Osage Orange? That will warm a saw up.

Thanks for the responses.
The bar oiler was blocked by a peice of what appeared to be packaging material. Very little oil was being dispensed to the bar and chain.
It runs fine now that was cared for.
I wonder if damage has been done to the saw as a result of the lubricant being boilied?

Glad you found the problem. I would just run it and see how it works. It may just work fine now. :thumbsup:

The most likely thing to be damaged would be the chain, and maybe the bar. You'll know when you use it next. I'm still confused by the fuel comment?

I too would be suspicious that the local dealer would make a comment about the fuel (assume it was in response to the bluing of the chain or bar). That he didn't decipher it was an oiling problem (lack of) or that he didn't set up the saw correctly (tested to show oil coming off the end of the bar), would make me wonder about his ability to sell and service Stihl saws.

If me, I'd go back to him for a new bar and chain. I doubt the rest of the saw is any worse for wear because of the blockage in the oiler.

Something everybody 'should' be doing on their own while using a chain saw. I can't blame dealer for this.

I would replace the chain. Once they get that hot the temper will most likely be gone and it'll dull very quickly. I would also run the saw for a little while, say a half tank, and then check the spark plug. I think there's a chance you could have damaged the output shaft seal and if so your mixture could be off. If it's too rich your plug will be black and it could foul. If it's too lean it'll be white and running for extended periods of time like this will kill your saw. I would also check the level of the bar oil, if you burnt a 1/2 tank of gas then you should have used about 1/2 tank of oil. If it's empty or full then you may have done some damage to the bar oiling system. If you bought it from a dealer I would have him check it out.

Contact Stihl and explain what has happened , I'm sure they will give you a new saw straight away . Stihl dealers MUST assemble the saw and test it before they give it to you , that is Stihl's policy . The blocked oil supply hole SHOULD have been discovered by the dealer , first by visual inspection when assembling the saw and definitely whilst testing it . The bar , chain , drive sprocket and possibly the oil pump (as it was not primed and may have run dry) are now damaged and I would think Stihl would just give you a new saw , they are a reputable company that enjoys public approval . They would replace the saw to keep you as a customer happy and also supply you with an uncompromised saw with full warranty . They will be flabbergasted at the dealers remark about fuel being the suspect .

I looked in my MS290 manual -- it recommends premium fuel:confused3:
I agree with Iron Horse -- I would be talking to Stihl if the dealer is not up for an exchange
