6400 Dolmar
Original equipment chain is not up to the the potential of the saw once changed the saw is excellent. Very little use but so far very good. Starting means no choke no throttle and first pull starts always. Really it might equal my super 120 Sachs 68 cc.

Good Saw, Bad Service.
Shipping was fast, but the saw was shipped with no padding at all.

The saw arrived with a nonfunctional oiler. ChainSawsDirect does not work weekends, so three days after I wrote for help, they replied that they couldn't do anything because it is illegal to mail a saw that has ever had oil in it. They suggested I seek repair at my local Dolmar dealer.

My local Dolmar dealer wanted 3 weeks and $50 to diagnose the problem, and told me they'd charge more if Dolmar gave them any trouble about... more

Best Decision Ever
I bought a Stihl farm & garden, it served well for small to medium sized trees. When several huge trees fell on my house, it was not able to easily cut them. I knew I needed a professional saw. I found that in Dolmar.

The Beast Of All Chainsaws!
I grew up cutting down trees, splitting and stacking wood. I have never handled a saw such as this one. It is a simple machine to operate and efficiently cuts the biggest and hardest trees. I can only say - buy this Dolmar and you will be quite pleased! Thx!

My Experience.
Took it out of the box. Put it together. Read instructions. Added gas and bar oil. Started right up, Ran for 20 seconds and quit. Could not get it to run for more than about 20 seconds on about 4 tries. Put it away. Next day it started right up and ran like a charm. Must have been air in the line? Although initially I thought it was the fuel tank vent. I dunno. Hopefully, it'll keep on running.

I love this saw. It makes my ms 290 look like a joke. Waiting for my 36" bar to come in this week. Build quality is really good.

Worth Every Penny
Wow, I had a Stihl saw. Now I have a Dolmar. I really felt the difference, The Dolmar cuts hardwood like a knife through butter. I've had the product for a week now and I have to say that I paid for a good product.

In a few months, I will probably write another review in a few months if I find something new to write about.

Thanks to Chain Saws Direct for supplying the chainsaw quickly. Highly recommended.

When It Comes To Bang For The Buck, You Can't Go Wrong With The
After much debate prior to spending money on a new chainsaw, and having decided that if I did that I would go with a pro series saw rather than a common name brand farm and ranch class of saw, I finally decided to purchase the Dolmar 6400-20.

I have been very satisfied with the quality and performance, and have no regrets whatsoever. I have felled and bucked several trees, including two that were 24 inches at the base and averaging 70+ feet tall, and haven't even had to dress the chain or... more

Great Saw
This saw has lots of power and the large fuel tank is a real plus. Started and ran great right out of the box. It really cuts fast lowering the amount of time spent cutting wood. Make sure you have a good hold of it - it's not a toy saw.

Great Saw!
The saw arrived in good time and in good condition. This user had a bit of a problem learning how to start it, but it did not take long to find how to accomplish this. The saw was put to work almost immediately after its arrival, on a Red Oak Log, with a diameter of almost thirty-six inches.

This saw did not have a bit of trouble sawing through this huge log, and continued to cut blocks fifteen inches long. Later these blocks were cut into quarters in order to make them light enough to... more
