Rachman Sentosa

A very powerful saw from our latest generation of large professional saws. The 390 XP® is engineered with the professional logger in mind. Designed for the most demanding conditions a logger may face. Performance is increased while vibration is diminished through Husqvarna's two-mass principle isolating the engine from the handles. Excellent ergonomics and low power-to-weight ratio makes the 390 XP® very desirable on the work site. XP®
