To get the fuel out take the cap off the tank and dump the old fuel into a empty gas can. Then mix up some fresh fuel using fresh gas and pore it into your fuel tank. Somewhere on the saw or in your owners manual the proper fuel and oil mix should be listed. Put the fresh fuel in the tank. There still may be some old fuel in the fuel lines so use some starting fluid so the old fuel is pulled through when you first start it.
Fuel needs to be mixed with 2 stroke oil at a ratio of 50:1
50 parts fuel to 1 part oil. Also it requires 'chain oil' used as a lubricant and bar coolant, this goes in the tank beneath the exhaust.
There is only one reason for excessive smoke from the exhaust, and that is because it is burning oil, and the oil can only come from the petrol ,so you need to refill the fuel tank with a fresh fuel/oil mix good quaility oil at 50-1 and try again. Is it possible you may have put chain oil with the fuel, or put it in the fuel tank rather than the oil tank?
Hello Andre;
I think you are saying you put oil/fuel mix in the oil tank and bar oil in the fuel tank; discovered your mistake drained both tanks and refilled with the correct fluids. Now the saw runs but smokes excessively. I think it will do no lasting harm. After you have run a few tanks of the correct mix (50:1) through the saw. Remove and clean the muffler and spark arrestor, reinstall them. Inspect your plug if any evidence of fouling replace it. I think you will be cutting with this saw for years.
Yes the additional smoke is caused by a very oil rich mixture and should abate with each fresh tank of fuel. If the chain is not moving ensure the chain brake is not engaged.
