Suitable for felling, limbing and bucking large trees, the GS 630 professional chainsaw is versatile, thanks to its high power and compatibility with guide bars 18-20" in length, without having to relinquish the benefits of low overall weight.

The Oleo-Mac GS 630 is equipped with a 51cm / 20" bar and chain and is powered by a 63.4cc, 3.5kW, 4.7hp two-stroke engine.

A digital coil, magnesium alloy crankcase and chain guard, automatic and adjustable aluminium oil pump, three-piece forged steel crankshaft and nickel-plated cylinder make this machine rugged and reliable.

At the same time, the primer and decompressor reduce the effort required for starting, while the nylon filter and the chain guard with a large discharge section allow for faster maintenance.

Finally, comfort is assured by an anti-vibration system with vibration dampers and an aluminium handle clad in soft rubber.
