Default Chainsaw Tachometer

I have read a lot about you guys using a tachometer on the chainsaw. Which one's do you like? This will be for homeowner use not a pro.


Thanks
Rich

Never heard of such a thing. The saw either cuts or it doesn't cut. If it doesn't cut, take the chain off, sharpen it, put it back on and go back to work.

I don't particularly care what rpm the saw is doing, as long as the chips are flying, I'm happy.

Are you referring to something like a Fast-tach? I believe they'll work on chainsaws but except for a service need, I wouldn't see the need for one. After awhile, you'll know if your saw is running at its top RPM (or not) just by listening. Normally, it'll start breaking up at higher RPM's if something is wrong.

This hast to a joke isn't it? There are so many critical things one has to observant of when running a chainsaw safely already. I can't even contemplate adding the observation of a tach to the mix.

Methinks consumer grade saws run 5-9K rpms with anti kickback chains & bars

Pro saws run to 11K rpm ginning up much more power.

I see no need for a tach provided the chain is sharp and the operator is at least as smart as the saw.

Tea something like the Fast Tach. But as other have said the need for one when adjusting the saw can be close enough to tune by ear.. So I save a few $$$ and listen better lol Thanks

No not a joke but not looking to mount a Tach on a saw it would be to fine tune the saw as a lot of shops use them.. But I try by ear till I cannt hear anymore lol

I'll suggest ear plugs or muffs and you can still hear it well enough to get the carb set.

I have the ear muffs that are mounted on my hard hat. I was kidding about the hearing ,as I am a old fart :) A Old farmer I knew could time a car by ear and to confirm it would hit it with a timing light, he was nuts on or pretty close. I am just new to working on saws so interested in things people use or do

Default Re: Chainsaw Tachometer

I too am an old fart wearing hearing aids, so I try to preserve what little I have left. For two strokes I warm it up, wind it up to the nuts and turn the high needle out 'til it starts slowing down a little then turn it back in 'til it speeds back up. Let it back to idle and turn the lo speed in until it starts trying to die, then back out 'til it idles smooth. Squeeze the throttle all the way open quickly, if it balks then open the low needle 1/8 turn until it will rev up smoothly. Then set idle speed so the chain just stops. This may take a little playing back and forth between idle mixture and idle speed. You may also have to tweak the high needle slightly after this. Hopefully your saw is old enough you don't have the little plastic EPA stops on the needles. What a pain!! And some are hard to remove so you get so it runs right.
HTH,
Mike

Mike great info Thanks. Very detailed My saw is new and yea EPA carbs , do not see those stops, I just need a splined socket type screw driver , which I ordered , I am planning on getting a older saw to practice taking apart and tuning. Had 2 at my Ex wifes house, So if I can find them I start there. if I screw them up no big deal, 1 is a old home light and the other is a Poulin , Something new for me to play with when I retire :)

LOL, after 4 shoulder surgeries I think I'd be more interested in an electric starter for my very well made old German Stihl chain saw that easily runs a 36" bar.
