Description
The Stihl MS 300 C-M Petrol Chainsaw 18″/45cm is a professional-grade chainsaw. It is designed for foresters, arborists and demanding users. The saw delivers powerful cutting performance with excellent handling. The MS 300 C-M is powered by a 53.3 cc Stihl 2-MIX engine. It produces 3.3 kW of power and weighs just 4.8 kg (powerhead only). As a result, it offers an excellent power-to-weight ratio for demanding forestry work.
Furthermore, the MS 300 C-M features Stihl M-Tronic 3.0 electronic engine management. The system automatically adjusts fuel metering and ignition timing to suit the operating conditions, meaning you can benefit from reliable starting and consistent engine performance. The larger engine also delivers 15% more torque than the MS 261 C-M. This helps the chainsaw maintain cutting speed in thicker timber. In addition, rapid chain acceleration provides responsive cutting performance which is particularly useful during demanding professional applications.
Powerful and Comfortable Professional Chainsaw – Despite its high performance, the Stihl MS 300 C-M is designed for comfortable handling. Its compact construction helps improve manoeuvrability. Low gyroscopic forces also make the saw easier to control. The improved rear handle geometry provides a comfortable grip. In addition, the Stihl anti-vibration system helps reduce vibrations reaching the handles. Buffer and spring elements absorb engine and cutting vibrations so the saw can help reduce fatigue during long working days. The MS 300 C-M also features a wide knee support to allow additional stability and control during demanding cutting work. Meanwhile, the direction lines on the fan housing help with plunge cutting. The vertical felling line also helps improve accuracy when felling.
Stihl M-Tronic 3.0 Engine Management – The Stihl M-Tronic 3.0 system provides fully electronic engine management. It automatically regulates ignition timing and fuel metering. The system responds to factors such as temperature, altitude and fuel quality. As a result, the MS 300 C-M provides consistent engine performance in changing conditions. Furthermore, M-Tronic simplifies operation. There is no need for manual carburettor adjustments. The chainsaw also features a decompression valve which reduces the force needed to start the engine. Combined with the simplified control system, it makes starting and restarting easier.
The Stihl MS 300 C-M 18″/45cm is an excellent choice for professional users, combining strong cutting performance with comfortable handling and advanced engine technology.
