Based on the number you don't see out here of any model, they pretty much have conceded. Which.. is somewhat sad...


I image Dolmar is like Stihl - they make it for Europe and are very reluctant to change the model for other conditions, and even more so if they have low sales. StihlNW had to seriously argue and twist arms to get full wrap, HO oiler and "hard" springs/buffers put on production saws... and re-argue for every model. It took 18 months to get hard springs for the 441, and it's still an "option" for now. I suspect it will become stock on the USA wrap models at some point. The HD filter across Stihl big saws was primarily because of the West coast and Australia. We still get those funny looking 044's (for service) from east of the mountains with non-HD filters....

Exactly, or Western Red and Incense Cedar, Yellow Pine, Redwood, Pacific Yew- I can go on and on. There's a reason Dolmar is coming out with this new air filter system, and it's not because the current system is working 'flawlessly' for every customer.

:agree2:

If their wasn't a problem why would Dolmar spend RD money for something
they don't need.
 
Those west coast guys have a point. Whole different ball game out there.

The new HD filter system looks just like filter systems you see on older Dolmar/Makita cut-off saws.

Now I know you are not supposed to oil any of the stihl HD filters. Does Dolmar say it is ok to oil these filters? If it is ok, I would assume it does wonders for filtration of the small particles.

The 7900 I am modding now, was used cutting dry doug fir for firewood to seat the rings. After bout 3 tanks the filter looked like it had been on a dirt road for 30 miles behind a NASCAR race.
Just knocked it out and finished, but with such a small unit it needs it more often than not.
Don't wanna sound like Tupac on the West Coast, but that is the way I see it.

It also blocks rapidly... Oiling went out a long time ago on Stihl filters. bad idea as it turns out.
 
Your pro customers in the east operate under different conditions than out here...I've run the 7900 series saws in the woods myself on commercial timber felling operations, and the filter couldn't make it through one shift without having to be removed and the fines knocked off of it. That's not acceptable here in a professional setting. The air filter system on that series of saws was designed for hardwoods primarily, and it shows. Long bars and dry softwood create much finer dust which is also a challenge for HD Husqvarna and Stihl filters. At least they can make it through one six-hour cutting period without needing attention. If you doubt this at all then I invite to come on out west and I'll get you up on timber sale and show you the results first hand.

Thats why I like living in the Atlantic North East I like my logs hard LOL

Its not a widespread problem its a PNW issue where loggers cut softwood as Lake just said They had to twist Stihls arm to get HD air filters as well

it's better than no work

Woah!
List price on that filter upgrade system is $80.00. Daayum.

So with the price of the 'Velocity Stack Filter' anyone know if there are any power gains with the Velocity stack part of this mod..
Seems like it ought to wake this series up a little. :)

It's not just a PNW issue, it's an issue for every state west of the Mississippi. Arizona and New Mexico has some of the biggest softwood on the planet, and the driest cutting conditions there is. Timber fallers in Idaho, Wyoming, Montana, Utah, and Colorado face worse working conditions (dryness, dust, powdery softwoods) than I do in Oregon/Washington. If it were solely a PNW issue, I'm not so sure Dolmar would have spent the time and money on an air filter set-up that has "7 times more surface area than stock filter" and "Largest filter surface area in the industry."

Stihl's earliest HD filter set-up (the metal-caged pleated oil-type) that came out here in 1986 actually worked quite well, and was the gold standard here for years.
 
The Air Filter on the PS7900 saw is not a issue I have hundreds of there saws sold and in service and if the user has any brains in his head he will maintenance the saw on a regular basis. As for the poster that says he cant make it through a single cut without the filter clogging I call Bullchit on that one... Im sure this new filter will sell but as far as it being standard equipment I do not see the need for that. Like I have said the standard air filter setup on the PS7900 works very well and it keeps the rear hood nice and rounded for more comfort espically for those who lean over their saws while filing. So Brad as far as the air filter being a known weakness I would not say that and I have hundreds of saws in the field to proove that myth wrong..

Alright, what I'm talking about is using the 7900 on WILDLAND FIRES. Do you have any ****** clue what it's like falling trees on a west coast wildfire? I'm not fond of speculation, but in this case I'm gonna go ahead and guess that you don't. I'm fairly new to it myself, only having done it for 8 seasons, but I've been a sawyer the whole time, running Stihls (with no air filter issues) on all but one fire, where I tried out the Makita, and it performed significantly worse than any saw I'd used on a fire before. And don't call me out about the filter clogging in one cut. To clarify, it was the backcut of a tree, so an actual cutter would recognize that's the third cut made when falling a tree. It was the first tree of the day, the filter had been washed and allowed to dry a full day. (as is how I operate, 2 filters, wash one at the end of the day, allow it to dry all of the next day while running the other, repeat) But seein's how I've NEVER had a stihl get clogged to the point of running poorly, and I've seen Huskies run on fires with no issues, I would say that yes, it's a piss poor design for fire.

Now how the F*%& can you call bs if you weren't there, or haven't run saw on a wildfire? I'm not sure if you know, but fires tend to leave a lot of ash behind, usually a few inches on the ground. Not to mention all of the charred wood that becomes a really fine dust when the saw cuts through it, and the fact that a running saw stirs all of that stuff up pretty bad.

I've heard a lot of talk about poor maintenance habits and dull chains just having to be the cause of my problem. Trust me, I take plenty good care of my saws. I tap out the filter after each tank, and either wash or blow it out at the end of the day. I hand square file my chains, and keep them sharper than 95% of people running saws. And again, these habits are more than adequate to keep my Stihls running well, but when I tried to do the same with the Makita, it needed even more maintenance, and got to the point of not being able to cut after 5 minutes of run time.

Commercial applications? Sure, cutting green wood, or even dead wood when you're in lush green, no problem. It's not that the saw can't stand up to being used all day every day. It can't stand up to being used on a fire. Stihls and Huskies have no problem.

You've got hundreds of saws in the field. How many of those belong to fire fallers?

:agree2: That nails it down right there.

Although not seasonal, working in the aftermath of Mt St Helen's ash would of been about the hardest on the life of a saw.
