I am helping out my husky dealer get cought up on work. He is going to give me a 2014 550xp for my work. Is there any thing I need to know about this saw.

Just give it a gentle start for the first 3 tank fillings. Most important is a varied throttle in order to give a good run in, with good cooling through fuel. Avoid at all times WOT at no load. Run it with the recommended 2% alkylat, eg Aspen fuel mix.

Forget about all the nonsense you've heard and read about calibrations and resets, that's mostly uninitiated hear says without substance.

Rather run the saw in real work situations, while it go through the training cycle, continuously adjusting to fuel choice, ambient temp, altitude etc.

At the end of the 3 tank run in period, give it some bigger bite to work with, to really adjust for it's max performance.

The saying, that the harder you run the saw, the better it performs, really is true. But give it a throttle variation, as all two strokes depends on fuel supply for cooling.

You might notice after using the saw for a while and your senses are sharp, that after lighter work as cleaning and light delimbing, the saw response has adopted to that low demand work. That's not the intended prime scenarios for this race machine, so you might let the saw go back to a higher work load, in order to get optimal performance again. Over time, using your musical ear, you'll easily learn to monitor the saw tuning state.

Check the tension frequently of a new chain, learn when to use the choke and high idle, monitor your start learning problems, though seldom happens, with a spark plug check up. Keep the chain sharp, and choose a 15" bar for best balance.

Read that owners manual it is in there about the calibration.

The way I did the new 545. Find a bigger log, start it and make as long as of cuts you can full throttle for about 5mins to set the the tune.

I think HolmenTree has pics here somewhere of what he did to calibrate his 550xps. As I recall it was some large logs stood on end that he cut a bunch of long cuts down the length to get the 5 min run in.

I just used mine in the course of normal use and didn't give it much thought?  My 550XP and 545 both work fine. Never gave the fuel rate much thought.

Both of yours have had the initial calibration 5min runs too. ;)
