Echo and Aspen...Hello,

[Ian C]

Had two 2511 from new for about 3 years, didn’t use bio and never had a problem!

I don't know but the part is cheap and you could try it. Sounds like you either have chip residue in your oil tank, which is a common one or the oil just isn't suited to these saws. You could try thinning it down with a suitable thinning agent, not sure what as diesel, petrol, spirit defeat the point of using a bio oil.

Not seen the Echo strainer but it may be worth trying a Husky or Stihl one if they fit as they are "strainers" rather than "filters" and will stop the larger pieces of chip blocking the pump.

Do you know when you purchased your Aspen chain oil which you are having trouble with?

 

I'm assuming you are using the old formula which like other bio chain oils will go off eventually and cause sediment build up which can cause blockages in the oil pump.

 

Our newest formula has been designed to combat this issue so you can use a bio chain oil without these issues ?
