The chainsaw market offers a wide range of equipment for harvesting and processing wood. Although the general principles of construction of this type of equipment are identical, regardless of the manufacturer, individual models are constructed with the specific needs of operators of this type of equipment in mind. The needs of the agricultural market are quite specific in this regard. Most of the work is related to woodworking, which requires the use of a saw with relatively high power at a low weight of the ready-to-work device, that is, a device with the most favorable unit power load. A very important role in choosing the right model of chainsaw is played by the ease of maintenance that guarantees the user maximum maintenance of the saw in serviceability. So an important factor is easy access to components that require regular maintenance, such as the air filter, oil filter or spark plug. Convenience and safety at work are also important. A vibration reduction system, a convenient chain tensioning system, a decompressor valve for easy engine starting, an inertia chain brake or an air filtration system equipped with a self-cleaning air filter play a significant role in this regard.
Among Oleo-Mac chainsaws, the GS 520 model offers ideal conditions useful for users from the agricultural market. The machine is powered by a two-stroke engine that meets EURO 5 emission requirements. Forged, three-piece crankshaft together with a cylinder that has a nickel-plated smoothness guarantee unparalleled service life of the drive unit. The self-cleaning air filter and spark plug are located under a cover equipped with a central knob for tool-free access to the controls. The side chain tensioner and decompression valve make it easy to prepare the machine for work and start the engine regardless of the working conditions and the digital ignition coil, controlling the ignition advance angle, allows the engine to reach maximum power regardless of the momentary load on the cutting system.
