Breaking in new blower

I recently bought the Stihl BR600. In the manual, it says not to run the engine at full rpm's until after you have filled up three times. Some of you may say, sure follow the manual. However, in my FS80R manual, it says the same thing. The tanks have a fairly noticeable difference in size. How long did you (owners) break yours in? I did this with my FS80 as the manual said. I just want to know about the BR600. If so, it's going to be awhile before I can see it's true power.

So the best thing would be to let it just sit through 3 tanks? at different speeds but not full?

Run that b*tch WOT...don't let up on it. "Break em in hard and they'll run hard" :)

I just avoid running them at WOT for an extended period of time at first. Vary the throttle speed too. I have an Echo 603, 3 years old and runs like brand new today! Also have a couple sthil handhelds. Both of these are tempermental as hell in the heat, but I blame the ethanol in all the fuel now.

When I bought my Stihl br420 magnum, I did the same. When I first got it, I ran it at idle for 30 mins, and for the next tank or so just varried the throttle speed.

I just got a br 600 as well. For break in period i am varying throttle. I did not go to full throttle (alright for 2 seconds to see its power... :) ). I only have .75 of a tank to go. Just do what the manual says, 3 tanks isn't that much time. Good luck w/ your new blower :waving:
