taken from 353´s manual, 3,1/3,2 (front/back) are the vibration levels... now look at other manufactures values and it should be clear that huskies vibration levels are significantly lower than others...
Jonsered levels are about the same, for some odd reason.....:biggrinbounce2: :hmm3grin2orange: :hmm3grin2orange:blis said:taken from 353´s manual, 3,1/3,2 (front/back) are the vibration levels... now look at other manufactures values and it should be clear that huskies vibration levels are significantly lower than others...
blis said:i doubt you have ran any of those new 300xp series saws (346xp, 353 for example), imo, i can barely feel the vibrations on my 353, nevertheless, havent run any dolmars so i cant say for sure...
Monkeyhanger said:Hi,
I think you are very wrong there. The 7900 is definately not the smoothest in its class! It has much higher vibe levels than a 460 and thats according to the figures from the manufacturer and the KWF. No smooth they are not.
I don't have the figures for the 5100 on my computer at the moment but the legal limit (in Europe/Germany obviously) is 12m/s and the 7900 has up to 9.5m/s on the rear handle and up to 9.1m/s on the front handle. Only the Solo saws are worse in that respect. Even a 660 has lower vibes than the 7900.
Using the figures means that to completely avoid vibration caused injuries you can only use a 7900 for 30 minutes a day! In comparison a 346XP can be used for over 4 hours.
The vibe levels of the 7900 are the reason I bought a 460 for myself. Of course your subjective impression of the 7900 may be quite different to the objective figures. I know that I won't buy a Dolmar until they sort the vibe levels out though.
Bye have a nice Sunday!

Come on now, These numbers are not something that Monkeyhanger made up this are the facts.Freakingstang said:Ahh, another one that knows all because he read it somewhere on the interent.
You think the 460 has good vibes? I'm really surprised Saw troll didn't eat that statement for breakfast, lunch or whatever meal time it is up yonder.
The 440/460/660 are the oldest form of antivibe, rubber mounts with no spring dampners.....
Just goes to show, that you haven't ran a dolmar. the 460 feels like a jack hammer compared to the other saws in it's class. The 385xp and the 7900 are both more precision and smoother on the operator, not to mention more power to go with it.
All i can say is to get some trigger time before spouting off at the mouth. I will bet money that 90-95% of the poeple that switch from stihls 044/046/660 to the 7900 will not argue about the vibration levels, yet the book readers seem to know what is best....
If the 460 is so great on vibes, why did they change the 441 to spring dampners to reduce the vibes????

Maybe, but you are again guilty of ignoring the dampening effects of the anti-vibe systems, which are way different on those models....:greenchainsaw:Monkeyhanger said:....
saw : idle front/rear : full throttle no load front/rear : full throttle loaded front/rear
MS460 : 4.7/6.5 : 2.6/4.8 : 4.8/6.5
7900 : 9.1/9.5 : 4.6/6.4 : 5.8/6.3 ...

Monkeyhanger said:Hi,
did I say something particular to warrant your insults? I got most of my information from the manufacturers handbooks. You do know what a handbook is don't you?
I was also not "spouting off" but rather trying to keep bias out of things and maybe get behind the claims of some manufacturers. Is that wrong?
As for "trigger time" I have been using chainsaws since 1987 when I first had a Pioneer 650 thrown into my hands. Does that qualify as "trigger time" in your world or am I still just a beginner "spouting off"?
I don't know what rattled you up so bad as I had no intentions of pi+++++ on your Dolmar or having a bash at you personally.
Whatever.
Bye
PS by the way Solo saws have steel springs too and also (according to their own figures) the worst vibe levels in the chainsaw market today!
Another thing Freakingstang you were about 7 years old when I was cutting trees with the Pioneer! Talk about spouting off...
B_Turner said:I would be interested to hear what those that own/run both the 460 and 7900 have to say about vibration levels.
I am the most concerned and fanatical person I know when it comes to vibration levels in tools both because my hands are my life as well as being extra sensitive to vibration in tools. I don't own a 460 (which is a great saw no doubt), but I have run friends 460s and in my opinion the 7900 vibration levels are noticeably better. I personally am thrilled that husky has been reducing vibration levels for a while and now stihl is finally doing it with the 361 and now the 441. But for example the stihl 660s I have run (and the one I own and run a lot) has a ton of vibration that can actually make hands tingle, so to single out Dolmar as a vibration problem doesn't jive with my experience. I love my 066, but generally use my 395 because it is two worlds smoother.
Bottom line for me is that I find the vibration levels on my 7900 in the cut very acceptable. Better than my 371 and much better than the 460's I have run. And much more fun to run than either of those saws, although reliability is perhaps an open question. And I've not run as many different saws as some, but of what I have run the only saws in the same size range as the 7900 that are any smoother are the new generation 575 and 441.
I agree with those that say the vibration numbers don't tell the whole story.
manual said:Now maybe I am confused, but are the vibration effect being taking off the front and rear handles, So that would include the springs or rubber mounts

Freakingstang said:Actually I was eight in 1987.
As i said earlier, the 460 is not a bad saw, but trying to compare vibes on the 20 year old design saw (regardless of what the #;s say) to a newer, smoother, more powerful saw is like picking on the fat kid in school.
manual said:Nothing wrong with rubber mounts as long as they are effective.
If it passes the vibe test and is doing better than the springs then why change it.
Freakingstang said:Then why do the new stihls have the springs? (361 441).
Rubber doesn't dampen vibration feedback to the user like the springs do, but i suppose if the engine actually produces less vibes, then they would be sufficient like they have for so many years.
Freakingstang said:That is a very good point. Maybe that is where the difference in opinion lies.
To see the #'s say that the 7900 has more vibes at idle doesn't tell the whole story.
i can let my 460 idle and the 7900 idle for days. The 460 will not stay in one place, the vibrations of it make it bounce around, where as the 7900 will for the most part sit in the place it was left.
The engines themselves might be where the vibes are produced, but the important # is where the vibe levels are felt at both handles.
With that being said, the 7900 has less vibes on both the front and rear handles than the 460 does. i can run my 7900 all day and not feel any strain or fatigue, yet the 460 tires my hands and arms after about 3 hours of good solid use.
Easy, two words.Freakingstang said:Then why do the new stihls have the springs? (361 441).
