Chain SawsHigh quality and user-friendly performanceEngineerTakamasa OTSUJITalks about 390SXNever compromise on usabilitywhich does not show up on figuresIt is engine performance which determines the quality ofchain saws. An engine with high displacement will increaseengine power proportionally, which, on the other hand, willmake it more difficult to confirm to emission regulations.Therefore, we set a target – “Reduced emission andincreased power.”While conventional chain saws with equivalent enginedisplacement have an output of 63ps per liter, we set atarget of more than 65ps per liter for “390SX”. We are proudthat the “Japan Technology” label represents the highestlevel engine development. However, from a fundamentalviewpoint, we realized we must investigate closely eachpart for improvement and took various new approaches. Asa result, we reduced harmful substances to one-third and,moreover, achieved an output of 67-68ps per liter, which ismuch higher than our target.Pursuing not only “power” and “conformity to emissionregulations”, but also usability remain characteristics of ourproducts. It may be the case that when replacing machines,usability changes between former models and currentproducts become a concern. Taking this into consideration,we worked on maintaining the user friendly features ofconventional models as much as possible. We are surethat you will like “390SX” which has the same usability, highpower, and speed compared to conventional models.The choice of Chain Saws in 2013: "390SX"n Chrome plated cylinder with Y-port system(Patent Pending) for extremely better durability,lower emissions and better fuel economyn Great power to weight ration Heavy duty 2-piece crank shaftn Magnesium crank case for light weight andextended durabilityn G Force Engine pre air cleaner systemDual postfront guardAluminumfront handlekW/kgGreat power to weight ratio11%UP!High Power &Excellent cutting performancePower in operation390SX389S390SXkW389SrpmSoft-start67
