how hard a chainsaw must be pushed ?

[Anthony_Va.]

Just listen to the saw at WOT. You hear any type of sputtering at all then you are close to being right. Don't mess with the low unless you have to move the high a good ways. If it's winding out and sounds like it's gonna blow, then you need to richen it up. If you can't tell much about the sound, take it to a dealership.

I didn't read through all the posts in this thread, but one thing comes to mind. The clutch grabs tighter the faster it spins. By running partial throttle, it's very possible, even likely, that you'll get clutch slippage and the clutch will burn up in short order.

From the site showing your saw

Am I reading it right that the high rpm is only 7000? Wouldn't that only be about 3/4 throttle compared to most saws already?

It is not the "high" (= max recommend) rpm, it is the max power rpm.

Normally, that number is between 9000 and 10000 rpm on modern saws - even some late 1960's saws had max power at higher rpm than 7000.....

"3/4" is about right - but it has nothing to do with the throttle position - those numbers are only relevant at full throttle, under load!

so basicly it is ok not to push the saw to the max ?

Don't worry about your English, we'll work through that. Your English is probably better than our Transylvanian.

But...when a whole bunch of different people, some of whom don't even like each other and probably couldn't even come to an agreement on how many hands a clock has, give you the same advice you'd do well to listen.

There is an absolute wealth of information and help available on this site. Take some of it.

Great post!

Um... always run a saw at WOT while in the wood.

This.

The throttle should be regarded as an on/off switch - and if you have to put much pressure on the saw, the chain probably is dull, the rakers too high - or something else is wrong!

And this.

Are you wearing hearing protection while you cut?
The sound of my saw doesn't bother me a bit when it's running wide open.

And this.

providing your saw is tuned properly it is best for the saw to run it at full throttle. Do not run at part throttle unless making a delicate cut. Saws are designed to run at full throttle or to idle. It is NOT a car.
your L screw controls how much air gets to your engine at idle and how well it revs up to operating rpm.
your H screw controls how much air your saw is getting at full throttle. It is important that setting is correct. Your saw should not sound smooth when revving at full throttle out of the wood. When you enter the wood under full throttle it should smooth out in sound. The other screw you have controls what rpm your saw idles at. You seem to be asking over and over so let me say it again. YOUR SAW SHOULD BE EITHER RUNNING AT FULL THROTTLE OR IDLING.
