Husqvarna Autotune Calibration

[TGB]

A query, in print Husky say to run at "8-12,000" or full throttle. It also mentions "... for 3-5min.)

 

Does that 3 to 5 minutes or does it mean 3 to 5 cuts

I didn't do this and my 550 is running like a beaut.

A query, in print Husky say to calibrate the'Auto Tune,

"... Accelerate the engine to full throttle and saw a number of cuts in a thick log (3-5 min.).

 

The chain saw must be run at (8,000 - 12,000 rpm) the entire so the carburettor can adjust itself."

 

Does that mean 3 to 5 minutes or 3 to 5 cuts?

 

I notice with the Stihls, one just has to let it run in start mode without a throttle input for 30 seconds.

 

Note. Uh sorry about the second post, couldn't edit the first one.

3-5mins full bore burried deep with the chain razor... This can be done any time you need to recalobrate the auto tune.

Try not to let the saw run dry as the auto tune can calibrate being run lean in to its settings thos can make them a pig to restart after fueling and run a bit off untill its re calibrated itself, dont leave the saw ticking over for an amount of time either and also do not be tempted to run the saw dull or blunt this also seems to effect running.. Hence why I do not let others use my saw , they are a one person saw IMO.

All very helpful stuff, gonna give it a go when the break has been fixed, went ping for no apparent reason yesterday, is that a common thing?

[MattyF]

Ha ha yes , it's worth keeping a spare!! I have only done one though...and there's a knack to refitting husky brake bands.. I think from memory its doing the end nearest the front of the saw first. ??

Well it's still under warranty at the moment so it's gone to the dealers to be sorted

[MattyF]

Good that will save you some frustration !! I only had the starter pull break under warenty the band lasted over a year.

[Coletti]

It's a 2 year warranty apparantely? Or so my local dealer told me last night

I could not work out if it was 3-5 minutes or 3-5 cuts minimum ? Any weay I just cut full width of the bar in a big chuck of ash and all is well .
