Makita too

Here is the blue version...

Makita DCS9010 (I'm thinking the "DCS" stands for Dolmar Chain Saw)

<img src=http://www.makita.com/res_tools/images/ope/dcs9010_l.jpg>

Makita web site lists the saw as 11,800 RPM which must be old- Solo lastet info has the Solo 694 at 13,500 RPM 6.9HP :D

Just thought I might add shed some info on the post.

Yes, the Solo 694 is a Dolmar PS9010.
It tops out @13.5K being electronically governed not to blow up

Due to it's design, it has more torque than any other saw in it's class. Designed for long bars, and ripping.
Many of Dolmars designs have been copied, or the patents are now off.

Their new "bubble" saw incorporate a new 'Air Master' air cleaning system unlike anything else on the market. The 4 & 6 port cylinders cut like pit bulls chewing into the wood.

I never ran saws like them before.
 
Some are open, and some are closed port.

PS9010 uses 4 transfer ports. Torque is gotten thru a variety of ways. Attack angles, port timing, asymetrical power flow pistons.

New "bulbble saws (my name) are 64, 73 & 79 cc.
The 64 or 73 cc model uses six open port jug.

Will try and let you know. Try cutting with one. Awsome power.l
 
So, are you saying that the cylinder uses 6 open loop transfers? Or 4 open loop transfers, and the intake and exhaust ports count for the other two? I understand how torque is made...any idea of the port timing figures on this saw? I may just have to buy one to find out....I would like to see why this saw is supposed to be better than the rest....why "bubble" saw??
 
bubble saw

He's refering to the shape of the saw. Here's the new PS-6400 Seth 2002
 
"bubble saw?????"

OK if you think so...
here is a pic of the PS7900
79cc 5.8hp

Sorry I did not mean to preturb you,I don't know if Dennis has seen a picture of the new Dolmars , sawman called them bubble saws, so I thought I would show a picture of the 6400 to help shed some light as to why sawman refered to them as a bubble saw. Seth
 
I ran a 7900 at Boonville, and while it is a very nice saw, good power, light weight for it`s displacement, and pretty good anti vibe, I wouldn`t rate the saw as anything phenomenal. Especially when you consider a couple of factors such as what kind of dealer support you are going to get with a thin dealer network and it felt like an ~ 6hp saw for $700. My point being is that it isn`t a deal enough to make me want to take a chance on one, especially knowing who the distributor is in this area, from my past experience they will screw you given the opportunity, well maybe not outright screw, but they won`t be backing up many warranty claims and that`s the same as not having a warranty isn`t it?.

They use 4 closed transfer ports on some models, and 6 open transfer ports on others.
Not counting intake or exhaust ports at all.

No idea yet on port timing.

Air Master is a unique way to draw air in from the cleanest area, the upper left, pull it through two chambers that reduces noise, and lets big dirt flow out the other side of the air filter hood.

Cleaner air goes into the carb box area (second chamber). Air filter is flat on top, and stippled(wavy) underneath. Filter is tilted so dirt can vibrate off.

The neat thing is there are two rubber flaps in the bottom of the carb box, aside of & below the carb. When the throttle plate(trigger) is open all the air goes into the saw creating a low pressure.

When the throttle plate (trigger) is closed, high pressure is now created, causing the flaps to open, and the dirt FALLS OUT !

Benefits are quieter, cleaner air, better cooling as the air isn't split/diverted like air injection but pushes more air across the cylinder, etc.

The 79cc blew my mind with it's weight being less than a Husky 372 on the scales( sales lit is off), and more power about equal to a 394 running 20"-24" b&c .

Also like the carb is flex rubber boot mounted, oversized muffler, side chain adjust, no tools air filter cleaning, left side d'com valve(won't burn fingers), and huge av mounts.

It just looks...big. But it's easy to service. Somebody was thinking.

Gotta try it.
 
Hey, troops, not to gloat, but I brought this saw to yo'all's attention 7 months ago. Best pwr to weight ever!! 6.2 hp, 13. 8 lb--and Sawman thought it is lighter than a 372, which is supposed to be 13 or close- if it has the small dogs and half wrap handle anyhow.

Some of the links are no longer up at dolmar.com, including the full specs. That saw has beaten out Stihl's and Husky's handily in Euro saw competitions.

Sawman, good to hear you were impressed with the saw. Jokers, give it another shot, maybe.

I've never seen one, as there are absolutely no Dolmar dealers anywhere near the PNW. But I surely want one.

Don't mean to throw fuel on the fire, but I saw something that made me blink.

Couple logger-hunting buddies and I were cutting with two Dolmars, one saw had Oregon LP, the other the new version of Oregon VG. The LP cutter with the newer(lower) flat top depth guage.

Switching saws back and forth, both clear cross cut the same, the LP just a hair faster with the bar & nose buried notchin.

Most felt that they liked the LP because it "felt like it was cutting."
That's the funny thing, they were basically the same, except the VG was alot smoother. Oregon rep says it's a vibe reduced chain.. so it's supposed to be smoother, and better on the hands...?!

Point being, maybe I should really give something a fair trial before I kiss it off.
Just like my new truck. Been a GM man 25+ years, but had a Mercury(Ford), that worked real good. Looked at them again.
But that Dura Max just caught my eye & ear.
 
Hi Roger, the 7900 is a fine saw and I almost bought one the day I demo`ed it. There was a smaller dealer there who has a good rep and he just picked up Dolmar, so I felt that I could buy from a good dealer. But then you get into relying on THAT distributor that I mentioned earlier. I hate to say it but I`m going to wait and see if Dolmar becomes a presence in this area before I buy one. I didn`t see that 7900 as the big Husky killer that sawman sees, in fact I had just run a stock 385 to compare to my Greff 385, and I`m convinced that the stock 385 has more juice than a stock 7900, although the 385 does weigh 1 1/2 - 2#s more, but the price is about the same. And there are Husky dealers everywhere should I ever need one. I didn`t sense that the 7900 is lighter than a 372, atleast with a halfwrap, infact I thought it was heavier, by feel, not looking at literature. My overall opinion is that the 7900 is more like the 460 Stihl, heavier, pricier, and a little ballsier than the 372. It does have much better anti vibe than the 460 and as an added bonus it runs D009 bars, the same as the bigger Huskies. I`d like to know more about this saw blowing away the Stihls and Huskies in European competition, are we talking stock saws or modified? It does have an impressive power to weight ratio, but I`m wondering how much it is already hotrodded from the factory to get it, and how much potential is left. Factory hotrodded is a good thing for the average guy I`d say, but for anyone looking to build a saw, how much potential is left? I don`t know, that`s why I`m asking.
Sawman, maybe it`s just cobwebs in my head this morning, had to skip my morning coffee, but your point about the different chains is a little vague isn`t it. I`m going to surmise that you guys were running small cube saws if you were running VP on one of them, so consequently the LP you refer to would be the .325 with bumpers, not the full grown 3/8s LP, although the baby LP does have a good sized tooth. So my point being, that small cube saws are inherently less powerful and performance can be more easily influenced by the size of the bite being taken, meaning that maybe the LP is too much chain for whatever saw you guys are running. As for your analogy of giving things a second look and being a Chevy man but still looking at a Mercury, you know that you will be supported by a dealer at nearly every town and city in North America, whatever brand you choose. That`s painfully "not so" with the Dolmar line. Consider the fact that Roger can`t even buy one. I hope this changes because I`d like to see more quality saws on the market, but with the distributor here in CNY, it`s not going to happen unless it happens by itself. If Dolmar doesn`t take off in a big way, quickly, the existing dealers are going to be left out in the cold when this dist. hightails onto the next flash in the pan. I hope I`m wrong because I liked the saw well enough that I want one. Russ
 
Thanks for the input, Russ.

The press releases on the Dolmar website now seem to be gone. But the competitions sounded like overall tree cutting skills. I dont really know, as no details were given.

The recent talk about a six port design interested me....

Light weight and power is very applicable to me, for in the tree use, as well as comfort on the ground, so i still want one. The filtration system sounds even better than Husky's, too.

Why I should want more than I have is crazy. I can bury the 32" bar currently on my Walkerized 372, at least in Doug fir, and still it cuts like a banshee. It is so good, i rarely break out my 066 anymore, but grab the 3120 for bigger stuff...
 
Thanks for the reply Roger. I didn`t get to use the 7900 enough to check out the air cleaning abilty, but I did look at the filter before and after and it was clean both times, not even so much as a visible chip. To want more than you already have is the necessary driving force that makes some people more successful than others, isn`t it? More power to you! I`ve seen plenty of evidence that you are out earning what is your`s rather than trying to swindle someone, BTW, very interesting thread about dumping that fir in close quarters. With my limited experience with Walkers, I would say that they have a very good product, worth every cent, but wait till you run a KD372! If I can ever get someone to run my camera while I cut I`ll show you what a KD372 sporting a 34" bar looks like in big maple! Impressive indeed. Russ
