Gasoline chainsaw 51.51

Machines designed to meet the needs of a wide range of users. Their compactness, versatility and a good power-weight ratio ensure excellent cutting performance for any use: limbing, pruning and cutting of medium size trunks. The crankcase is made of magnesium (models 51-56 and 62). Magnesium ensures a lower working temperature of the engine and a lighter weight of the machine. A silver plated needle bearing is used on the crankshaft to reduce working temperatures. The cylinders and pistons have been specially designed for chain saws. The piston rings are made of a special material to guarantee a longer life of the engine. The intake air is pre-filtered by a special device.. The digital ignition ensure an easy start and a constant power in any working condition. A special ceramic is used on the spark plug to guarantee a “cleaner” engine, due to a better combustion inside the cylinder. Some models are equipped with a decompressor to guarantee an easy start with very low effort. This device eliminates the kick back and ensure a longer life of starter components
