The Oleo-Mac GS 630 professional chainsaw is a powerful and versatile tool that is ideal for felling, limbing, and bucking large trees. It is equipped with a 51cm / 20" bar and chain and is powered by a 63.4cc, 3.5kW, 4.7hp two-stroke engine.

The GS 630 is made with high-quality materials and components, including a digital coil, magnesium alloy crankcase and chain guard, automatic and adjustable aluminium oil pump, three-piece forged steel crankshaft, and nickel-plated cylinder. These features make the GS 630 a rugged and reliable chainsaw that can withstand the rigors of professional use.

The GS 630 is also easy to start and maintain. The primer and decompressor reduce the effort required for starting, and the nylon filter and the chain guard with a large discharge section make maintenance quick and easy.

Finally, the GS 630 is comfortable to use, thanks to the anti-vibration system with vibration dampers and the aluminium handle clad in soft rubber.
