Up for sale is working condition commercial grade Echo PB500-T backpack leaf blower. I last used it about a few weeks ago.
I only use TruFuel 50:1 gas mixture for this blower. There are some fuel in the tank for testing and validation of the blower.
You can also obtain the Operator's Manual directly from Echo USA site (https://www.echo-usa.com/getattachment/4293ee2a-0d3b-42ef-bef3-9d6821f6f188/PB500HTes1112_111309.pdf).
