I have a new Stihl 250 (2days old). Been thinning the brush with my new 1025r. Taking down small trees and cutting them up etc. My chain oiler seems to be clogged. Took off the plate and did a quick cleaning but still doesn't work. I doubt it's the pump. Does anyone know of a quick fix, shop vac, compressor blow out etc. I just moved here and am literally working off the floor. My shop is apart and my tools in boxes on the floor. Would appreciate any help. Why would it clog this early ?
