First let me say I am new to the site and new to PRO saw. I have been researching for about 6 months and have visited "Arboristsite"many times to help me pick the saw that I wanted. Thank you to all the forum members for posting such helpful info. This is not my first saw but is is my first NEW saw and I wanted to invest in a good one this time.

My concern/question:

Before I started the saw I took the clutch cover off to do some inspection and observation, greased the bearing, checked chain tension inspected the air filter yada yada... right after that I ran the saw to "set" the Autotune. I had it buried in some big logs for a good 5-7 minutes right after the first startup (temp was about 45 F). Then I took it out to start doing what i got the saw for. Clearing wide (for a truck) trails in my new 20 acres of woods and feeding my small basement fireplace. I ran just under one tank before it got dark. a few day later (today) I decided that I wanted to dump the gas out of the saw ( the dealer put it in) because I new I wasn't going to run it for another week or two with whats going on and I wanted to put fresh gas in with MY oil mixture the next time I ran it.

I proceeded to dump it out. then I pumped the priming ball to start the saw because I wanted to run it out of the "carb" as wall. The saw started just fine. When it began to idle the RPM's went up higher than what i remembered form the first time. I took off the chain brake and the chain started running kinda fast. I was surprised a little but let it go for a second. I assumed the RPM's were higher than normal because it was colder ( 16 F) and it was probably leaning out form running low on gas. I put the brake back on to stop the chain and let it idle some more ( still high). I took the brake off and again the chain let loose. after that I shut it off. from the time I started it to the time I shut it off was probably just over a minute. I looked at the priming ball and it still had gas in it.

Is is normal for the chain/saw to do this in these circumstances? The saw did not do this at all the first time I ran it and my pervious saws (cheap big box store saws) never did this.

Thanks for the help.
 
Well, in my experience with running a 550xp and running it out of fuel, it quit fairly abruptly without the usual high revving lean condition due to running out of fuel you get with a normal carbed saw.

But having said that, you had already dumped all of the fuel out of the tank. I would speculate that even an AT saw will rev due to leaning out with nothing but air being picked up from the tank. AT can only compensate so much for an absence of fuel.

You can verify one way or the other easy enough... put some of your fuel in it and fire it back up. If the high revving persists despite the presence of fuel in the tank, I would say you have a problem. If not... you have nothing to worry about.

thank you sir.

my only other thought is it wasn't fully out as its hard to actually dump it ALL out of the tank and the ball still had some in it when i shut it off so maby i never actually "ran it out" does this make sense.....or no ?


EDITED: and would the 16 F affect it this way at all.
 
Oh yeah, the chain will run if clutch engagement RPM is achieved. It doesn't matter if engagement RPM is achieved via your finger on the throttle, or due to a saw revving higher because it's running out of fuel.
 
so are you saying you have had this happen with your saws before? the chain thing i mean.
I log for a living and sometimes I run the saw completely out of gas to get that last log bucked. The saw will definitely lean out.
 
thank you fellas. I wont be testing it out with new fuel until its time for me to actually get back out into the woods again.
 
did you blip the throttle to get it off high idle?


no sir.
I will try that if it happens again. the baby finally fell asleep in the living room and I was just outside the house doing it. didn't want to wake him up. also didnt think of that though. ;)
 
Welcome to AS and don't be a lurker :)

Thank you, I assume by " don't be a lurker" you me be active on the site. I will be as active as i can be. Iv never really cared at all about saws.....until I got this new XP. I may have caught some kind of bug or something. is there anything i can take for it? ;)
 
anytime you engage the choke to start the saw the next phase is fast idle when you flip it off choke. then you need to blip the throttle to idle it down

Thanks for the advice. now that you say it i have never really done that intentionally on a saw but I do it all the time with everything else.
 
Yeah you can take something for it...."Take" your keister back to your dealer or over to the trading Post here and start filling the rest of the size class categories with more saws! Lol! It's called "CAD" and the only cure is to acquire more saws...

Lots of good people and information on this site, thats all i meant by it. Roam around, pick up tips, learn some recepies for camp cooking, ect... it is a good place to come and just BS too.
