Echo CS-450P compression number help

[hatfield]

Does anyone have any numbers on a 450 ?
Thanks

Anyone have a 450 they can pull a number from.
Thanks

I don't have a cs450, but I have checked a couple of stock Echo cs400 models, and they registered right around 150 psi on my gauge.

Thanks for the response m21bmr. I appreciate it.

I called ECHO USA earlier today. They said the compression for the 300 and 400 models should be no less than 110 and no more than 130
I guess the engineers figured that's where they want them to run at ?

Almost al of my Echo saws have been 145# or above on my gauge unless the have scoring. My best saw make about 160 on the same gauge. Stevev

Hi Steve.
I figured it should have been around 140-150 as well. But, that's what ECHO told me for these models ???

Sometimes the guy giving the answers is more like a talking textbook rather than someone who has put a compression gauge on a saw. No real surprise there.

Hi Steve!

Here is the 450 IPL:

Here is the 450 spec page;
https://www.echo-usa.com/Support-Help/FAQs

The system takes out the model number on the redirect from my link. ENTER cs-450 exactly on all the search pages, including the hyphen.

At the bottom of the spec page you will see a red link labeled:
