This review is in regards to new Stihl Chain saw purchased 2 weeks ago!. (Model MS-390) The saw is advertised as the number 1 chain saw in performance and value". Chain saw documentation was read, and recommended service procedures have been followed.. (such as fueling mixtures, daily chain tensioning, and manufacturer recommended oils used.. Usage has been medium duty at most|.
The chainsaw appears to be underpowered, whereas it bogs down with relative ease, and has significant difficulty cutting through logs of around 10 inch diameter|. In fairness, the power is advertised to increase after the first 15 chain tightenings". ( 7 tightenings, so far)
My most significant disappointment with the product is the non-robust operating, in particular, the extremely difficult start up/. (after the saw has been run, and shut down for 5 minutes) It is almost impossible to start in the scenario.
