The Oleo-Mac GSH 400 is a gasoline chainsaw designed for private users who need reliable performance for cutting branches and firewood. With a 2.3 HP engine that delivers 1.7 kW from its 38.9 cm³ displacement, this model combines power with easy handling. It features a 35 cm cutting assembly with a 3/8 x 0.050 pitch and gauge, suitable for various woodworking tasks.
