Aluminium components are built into the plastic to strengthen the crankcase

Walbro WT diaphragm carburettors with primer are used on all engines. Diaphragms are made of a special material (Mylar) used to guarantee good and long performances even using unleaded fuel with high percentage of alcohol and/or alkylic fuels.

On some models (51 – 56 and 62) the oil pump is made of steel. On all models the pump flow is adjustable. The pump ensures a correct lubrication of the chain and of the bar.

On all models two bolts are used to fix the bar to the crankcase.

A larger cap on the gasoline tank makes easy the filling operation. All pipes are manufactured in Viton, special material resisting to unleaded fuel corrosion and high temperatures. Special device to avoid Vapor-Lock.

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

Powerful high torque engines ideal for the use in any condition (including farmer and professional use). Active chain saws engines guarantee high performances.

Three or five special rubber shock absorbers are used to reduce to the minimum the vibrations.The maximum operators confort is guaranteed.
