Echo CS 510 or CS 520

[Bad Cut]

Hey Bad Cut,

Welcome to the site! I have an Echo CS-510. It is a pretty strong saw once the muffler is opened up. I don't believe there is any difference between the CS-510 and the CS-520 other than the displacement.

Echo CS 520

Well I bought a cs 520 and I do like it.I put about two tank full of gas threw it and it does run very good.Last fall I also bought an Husky 346xp.Do I need a Dolmar PS540?

 

[sedanman]

Probably not but get one anyway. I have 15 or so more saws than I 'need'.

CS-510 is a good saw. Only complaint I have is that the gas filler opening is a bit too small.

CS520 has .325 chain

My CS520 has .325 chain on it and a rim and drum sproket.The book that I order my parts from shows that a CS510 has the 3/8 pitch and an open sput sproket,could someone with a CS510 check to see if they have a 3/8 pitch chain on their chainsaw and let me know.Thanks

I believe that the CS-510 came with both 3/8" and .325 and that they switched sometime in the production to the smaller chain. Mine has .325 altho in the owner books it says 3/8".

Go figure.....

The main difference is a CS-510 is a Phase 1 emissions EPA rated saw. The CS-520 is a Phase 2 emissions EPA rated saw. All chainsaws manufactured in 2005 will have to meet phase 2 EPA emission requirements. The CS-520 is rated in 300 hour category "A" this is good. As a category "B" chainsaw is only rated at 125 hours. And the category "C" chainsaw is rated at 50 hours.

CS 520 clutch

Can someone tell me if their is special tool to remove the clutch from the chainsaw so that I can replace the Sproket?

 

[premix]

Don't know about 520 but my 510 you have to unscrew a tight clutch hub. Can't remember for sure but I think its a left hand thread. I made a tool out of aluminum and a Bridgeport mill as you don't want to hammer on this area. I did not check and see if they made a tool for it.

Premix, I am just curious if I am interpreting these hourly ratings correctly. I thought that the letters a, b, and c were hourly ratings for how long the engine would meet phase 2 emissions as set up from the factory with correct maintenance. I am taking your post to mean they are giving an estimated engine life. This seems like too low of an estimated life span to me. Can someone verify this?

 

[brent denny]

I say this because I see those ratings listed as a "compliance" rating.

You are correct in that "how long the engine would meet phase 2 emissions as set up from the factory with correct maintenance." The saws should not stop running it is just that they are going down hill on ring seal. Becoming less efficient emission wise because of increased blow by.

This is still not the whole story. The manufacturer has to pay to have each engine certified, the 'higher' the certification category, the higher the cost. Many of the manufactures elect to save some cost here and only spend the minimum to be legal. Echo chose to spend big bucks to have all of their engines certified to the highest level. The advertise that fact and twist the info to imply that emissions certification equates to build quality or overall longevity of the machine. I had an Echo salesman tell me that the Stihls and Huskys everybody is selling are powered by 'cheap disposable engines, they're all junk', I threw him out and told him to take his Fisher Price garbage with him.

 

[max2cam]

Don't know if it's still true or not, but a while back there were lots of BRAND NEW Echos on eBay that sold pretty cheap......sometimes dirt cheap.

I was also curious about the flood of Echos

on eBay a while back. I got sniped on a NIB CS3450-it went for $142.50 + $15.00 shipping. Some CS4400s sold for under $200.00. I think the CS3400s were going for around $220.00-$230.00. Echo isn't Stihl or Husky, but it's a good product for the money (no, I don't work for Echo).

Anyone here know anything about the Echo flood?

Paul-the Echo rep you described sounds like a complete idiot. Did he actually beleive the BS he told you? One of the main rules of sales is be very careful in what you say about your competition; you don't want to risk alienating a potential client.

Can you list some of the many quality chainsaws that only certified to the category C 50 hour test?

 

[sedanman]

I will get back to you on this, I don't want you to pounce on me if I give the wrong info.

Seems Like A Good Place To Be...Non-Working CS-510

Hi. Even though no on has posted here in quite a while, I'm thinking that someone still has this type of chainsaw. Mine quite working and I'm thinking it's a carburetor from my experience with lawnmowers. I was also thinking of using Sta-Bil to free up the varnish in this and that it might eat the rubber in the carburetor, too, making it useless. Does anyone have any experience with this?

Thanks,
Charlane

Howdy,

I have two Echo CS-510 saws. I can try to help but I'm no expert. I have learned allot right here on this site. There are some good intelligent folks on here.

What is the problem with your saw, will it start?
