I picked up my new 395xp this evening. I was wondering if there are any special break-in procedures I should follow on it's first start-up?
Thank You in advance

Czed, what do you mean by heat cycling?I heat cycle for a few minutes
The break in procedure isn't do or die for Stihl but I would highly recommend it on a cheap saw.I have bought 5 new saws in my life. I ran them wide open from the first start just like I always run them. I still have all of them and they still run great. The oldest one is 34 years old.

that is a procedure i have not heard of.The proper way to break in a new chainsaw is as follows... For the first three tanks of mix, add a teaspoon of two stroke oil directly into the saw. This can be done no matter what ratio you run, 40:1, 50:1. During the these three tanks, make only small cuts and avoid over-revving the saw. This will make the saw run better and longer than If you skipped the break in procedure.

It also depends on how much you cut.The break in procedure isn't do or die for Stihl but I would highly recommend it on a cheap saw.

I learned it from a small engine mechanic on YouTubethat is a procedure i have not heard of.
My saws consist of 2 Husqvarna, Craftsman, Dolmar and echo. The oldest and newest being Husqvarna. I do have a Stihl but it's a 4 mix pole saw so I didn't count it, but I ran it wide open from the start as well.The break in procedure isn't do or die for Stihl but I would highly recommend it on a cheap saw.

similar to thisCzed, what do you mean by heat cycling?
I have mixed about 40:1 since I started cutting firewood.
As soon as you Skip basic maintenance, It's a matter of time before they failI'm not a text book saw mechanic but I try to do at least a half a break in procedure, give or take. All they need is little maintenance and they should last many decades.

You better know how to retune one if you go to adding oil. That actually leans them out. Though more oil is better for break in as long as it’s retuned properly every time you change the ratio.The proper way to break in a new chainsaw is as follows...

I'm a self taught saw builder and all I buy is parts saws. I cut trees with my rebuilds on a daily basis. I restore and reuse worn engine parts and I've been using this break in procedure not knowing if it's really necessary but I always retune as needed. Here's a picture of a badly scored piston I reused. The rebuild ran like new.You better know how to retune one if you go to adding oil. That actually leans them out.

I’ve never owned a new husky, but I’ve had 20-30 new stihl saws. Always ran them like I stole them from day one with 50:1 super no ethanol and stihl oil. Never blown one up or scored any pistons and I’ve put some serious hours on a few of them (to the point of pistons not having etching on them)
