Re: Dolmar 500V 4 stroke

Back on the subject of the 4 stroke chainsaw. 4 stroke saw is
probably a long ways from reality at this point. power to weight
is nowhere near what even the worst 2stroke saws have and if i
were to guess the price per hp is double. after those 2
obstacles are overcome i think it will be a good thing. i don't
care about the emission side of things. The torque and ease of
starting for some folks will make them appealing. That is what
sells the trimmers so i imagine those same attributes would sell
a saw.

ok I may have spoken too soon. the 335.4 according to the sales
flyer is the 360 degree engine and the product book doesn't list
it as the 360 engine so idk for sure which it is. ???
[/quote] I believe my 245.4 is a 360° as well as I have tried
running it upside down and it is fine....no smoke or tapping.

A weak 50cc saw weighting like a 70cc saw, no thanks! ::)

Where did it say it was 14lbs or heavier PHO? I've been looking
for specs but nothing in stone.

Likely the German Dolmar web-site, but it was almost 10 years
ago, so I am not 100% sure it was there.

Dang you can remember the weight of a saw from ten years ago.
You have a better mind then me.

Found where I quoted a post from a dealer in US back in 2009.
Posted by US dealer.
Well it's not really top secret, as most you boys and girls know
that Dolmar has been working on one. I personally have and
probably will always like two strokes as they have a place in my
heart. I may have to add a little more room in their for the new
Dolmar 4 stroke chainsaw. I was outside at the 2006 Expo and saw
the proto type 500V. Walked up to the guy and point blank asked
him if I could run it, I think I startled him and he said yes. I
suited up with chaps and a helmet. I picked up the saw and first
off I noticed how easy it started. I stuck it in the log and
WOW!!!!!!!!!!!!!!!!!!!!!!!!!!. I've never ran anything so smooth
in my life. It was smoo..........th and quiet. I enjoyed the
experience. Asked if I could get pictures and NOPE so you'll
just have to wait. I do have a picture of me using it and I'll
post it later. Was told production would be June 2007 ( sooner
than I would have thought ) with saws in US maybe August. Of
course this is projected and I would not write this as the
gospel. Pricing at a guess will be 450 ish. I don't believe
anyone could ever judge this saw without running it. Dolmar has
the technology. Dolmar Rocks.
Yes it was a 50cc engine. The weight was to me ( maybe I was
just excited to be able to run it) was light as it didn't feel
heavy and I didn't even notice it. Of course 90 per cent of the
time I had it it was in the cut. The power was different because
I just kept going over in my head how smooth it was but it was
not a 5100S. I would say the power is more like a 510 but I can
see where a novice or beginner would love the power.
As for design of the engine I can't say because I couldn't see
anything under that cover. The top cover looked a little higher
but not in the way at all. If I were to rate the experience of
this saw I would have to give it a 10 on a scale of 1 to 10 for
concept, design, and performance for what the saw is designed
for. Again, I'm not a fan of small 4 stroke engines as I've not
really seen one yet that I would rather run than a 2 stroke but
I may need to rethink that when I see the finished production
500V.
During the Louisville show we did a small test to run the
PS-500V vs the PS-510 and the 4-stroke was right there with it
in the three cuts, actually the 500V won 2 of the three times
with different users. The sound from the 500V is decieveing. It
does not sound like a 2-stroke but the torque is there and the
RPM is 12,500 no load. This saw is going to surprise everyone
next year when it is in production.

As if this was a elementary criteria for the
homeowner/firewooder who uses his saw a few hours a year...
We won't recapitulate what innovations have sprung out of the
husqvarna factory in the last 20 years, that might be a little
embarrising....

I believe it is safe to say so - looked more like a PR stunt
than anything else?

Years ago Lots of folks thought 4strokes wouldn't work very good
for boats, boy were they wrong, I would love to try a 4stroke
saw.
