Breaking in a new chainsaw

[paultracy]

Does anyone have recommendations for breaking in a new chainsaw? Would you run 40:1 instead of 50:1 for the first few tanks or be easy on the throttle for a while? The reason I bought it was to run a 24" bar and cut my larger stuff but should I baby it for the first few gallons of gas? I know years ago when I got a new snowmobile I was told to break it in the way I would normally ride but we did run a little extra oil for the first 100 miles or so. I was thinking of approaching the new saw in a similar way just wondered what your thoughts are.

My new saw from a few years ago is still not broke in.

I went the recommended gas 50,1 but it says in the manual that it should be run for 10 HR at half to 3qr throttle.
Still haven't opened it up to its potential yet [emoji23]. Only run it a few hours a year.

I would follow the instructions provided if none then none are required. I ran mine full out.

Do not run a richer oil mixture, I can't stress that enough. Run the recommended mix as too much oil can cause build up on the spark plug that can break free and scratch the cylinder.

For your first tank of fuel make sure it is always running with a load and keep it under 3/4 throttle aside from the odd burst of full throttle. After that, use it as you will but don't let it scream wide open without a load for the first few tanks.

Thanks for the advice guys. So in order to extend the warranty to 5 years I purchased 3 liters of premixed fuel with the saw, I will just run it thru and then stick with the usual 50:1 mixture with high octane gas. As per your advice Oaknut I will stay off the throttle for the first tank.

I have a Stihl MS211 and I use the pre-mixed fuel Aspen 2. For the first 2-3 tanks I avoided using it full out for extended periods of time. After that I just use it as I normally would. I like the pre-mixed Aspen 2 fuel.......a little more than mixing your own, but I might use 2-3 bottles of it a year so it is not that big of a deal.

I didn't know that too rich oil could cause problems. I always run 40:1. Might have to rethink that.
I remember the old days of 16:1 in a Pioneer 620.

I bought my stihl 038 about 10 yrs ago and went full out right from the get go with the recommended fuel mixture. I use it 2 or 3 times a years and has never had issues. I think it still has the same spark plug in it. I bought it to use it not to baby it.
Don’t do what I did but I think if you use the recommended fuel mixture and and go a little easier it will be just fine, especially if it’s a quality product from a reputable dealer.

One thing I was told on a small motors course was that gas is actually a coolant. Get it on your hands and you'll know what I mean. So, adding oil would actually make the saw run a bit hotter. I would never spend a nickel on premixed gas/oil but would simply follow the dealers recommendation first. After that period, just giv'er!

The Stihl dealer recommended it and sold it to me.
