No break in was mentioned by my dealer when I got mine last year. Runs like a champ. Its a beast!

The best way that I found to break something in is to run it the way you intend
to be using it in the long run, that way if any parts develop a memory, they will
become shaped or accustomed to your own particular style.

In short, use it 'normal' right from the start, no special way.

The 4 Mix Stihl line trimmers specifically state in the manual to break the motor in by running it at no more than half throttle for the first three tanks, per Stihl. I would run the first quarter tank at half throttle before cutting loose on the blower. Mixed gasoline motors always are supposed to be broken in with a richer oil mixture, this is the norm...so I wouldn't run any of those 100:1, etc garbage mix ratios...just the recommended 50:1.

Run it like you stole it, for a car that is. I ran it just like a blower should be run, and it runs great for being almost 2 years old.

When I bought mine last fall I ran it at full throttle as soon as I got it home, blew leaves for about 2 hrs, and went through a tank of fuel or two. Runs like a raped ape to this day and starts on the first pull after the initial firing from priming.

The only thing I do to them is pull the spark arrester screen out before I fire them up.

Some equipment has to be broken in and some doesn't. The manual will tell you. I always read the manual on equipment that is new to me.

First put it on the open tailgate of the truck and take off. It's always nice to get that out the way.

Use at least 93 or 97 octane gas. If you use the lowest octane you'll have trouble with carbon.

i have never seen 97 at the stations around me. the highest they have is 93 which is what i use for all my mixed gas

I have a 1 1/2 year-old BR 600, and it's really nice. Lots of power, and amazing on fuel. But on to your question about break-in. I would only run Amsoil Saber and 93-octane gas in this blower for maximum life. It really will pay off later, because you won't have any carbon build-up. The valves will stay clean, and it will run alot better than on a different oil. Plus Amsoil is alot less expensive than the Stihl Ultra oil. I would say run at 50:1 for the first three tanks, and then run at 80:1 after that. Take the spark arrester out too.

Other than that, adjust the valves after a full use this season when you have some free time, and then do it once every year. I just performed the adjustment on mine. It only takes 10-15 minutes, and is very simple. Mine went 1 1/2 years before it got done, and when I did it really made a big difference in the power, and idle running. You will really like your new blower (providing you don't happen to get a bugged one with problems straight from the factory). ;=)

Hopefully you won't, and will have it last many years.

If you want to ensure that Stihl will take care of this unit when it fails follow their advise that they give you on what gas and oil to use. This is not a two stroke banger that will run with any oil you can find.

He's right. Stihl will warranty the 4-MIX engine from failure for 2 years if you run Stihl Ultra oil, so you should probably do that. If you run a different oil, you loose the warranty (too bad they won't let you run Amsoil, which is better). Also make sure that your dealer has extensive knowledge and experience repairing the 4-MIX's. It will be a BIG help.

I use 87 octane and it runs fine. I'm about to switch oil and try some Stihl synthetic (white bottles) to see if it will make my 4 mix's run any better.

I always run my equipment full throttle right out of the box. I dispute the "half throttle" idea of break-in because the rings need full pressure to seat properly. Clean oil, air & fuel and plenty of cooling is all a properly designed engine needs. Let it idle and cool down a bit before shutdown after running it. I ran 87 in the Stihl trimmer and chainsaw once - I noticed they got hotter than normal and always use 89 now. They are definitely set up for 89.

you should keep the old back pac in case the new 600 goes down-reliabilty isnt the 4 mix,s strong suite. i use mine ONLY for leaves. you dont need the extra power for daily work

The 4-mix's are highly reliable. The only thing you need to watch with them is carbon buildup on the valves. Run a quality oil like Stihl Ultra or Amsoil Saber, mixed with 89 or higher octane gasoline and you shouldn't have a problem. I'd take the power and performance of the 4-mix over a regular 2-stroker any day.

if i did have a problem with the 600 i could use the WB blower for grass for a couple days untill i got it fixed. I think it would be better to get a little money for the 340 instead of it sitting in my garage not being used

Incorrect info. You run whatever oil you want as long as it meets the spec. Amsoil actually exceeds the specs of the stihl ultra. It has been discussed many many times on here. Stihl cannot void the warranty based on the brand of oil.

That BR600 is a great blower but...have you looked at the Shindaiwa 803B? Same price, or really close (Got mine for $475 before tax, with commercial discount) are it blows signicantly more air at a higher speed with a proven 2 stroke engine.

The BR600 (and any 4-Mix) is very easy to adjust valves on. It's like a 5 minute procedure. You'll need a valve adjustment kit from your local dealer. It's Stihl PN 4282 007 1001.

Here's a Stihl video showing how to adjust the valves

Not necessary for most autos and boats. But a must for lawn equipment such as blowers, weedeaters, hedge trimmers etc. This is what the manufacturers recommend too. I run 92 octane in everything. Worth the extra money
