Puchase 3/2009 on line. Used once. First chain saw I've owned. Blade dulled very quickly. Friend noticed that the chain oil resevoir was empty. Must keep that full or it gets to hot and dulls blade much to fast. Then it would not start because the primer bulb was leaking air. I returned it at store. Because it was less than 90 days they gave me a brand new one. Much to my surprise the neww one did NOT have a prime bulb. It starts fine without it and it cuts fine on branches 14" or less in diameter.
