Stihl MS 300 C-M Chainsaw

STIHL MS 300 C-M: The Next-Generation 53cc Forestry Powerhouse

The STIHL MS 300 C-M is the long-awaited, next-generation professional petrol chainsaw engineered to succeed the legendary MS 261 platform. Delivering a massive 3.3 kW (4.4 HP) output from a lightweight 53.2 cc displacement engine, this machine achieves an unprecedented power-to-weight ratio (just 4.8 kg powerhead). Designed specifically for commercial arborists, forestry contractors, and logging professionals, the MS 300 C-M features M-Tronic 3.0 electronic engine management, which digitally recalibrates ignition timing and fuel delivery in real-time based on temperature, altitude, and fuel grade. Equipped with a .325″ RS Pro narrow-kerf cutting system and Light 04 guide bar, it delivers sub-second acceleration ($0\text{–}100 \text{ km/h in 0.25s}$) for rapid delimbing, felling medium timber, and heavy firewood processing with zero performance fade.

• M-Tronic 3.0 Engine Intelligence: Features an enhanced self-calibration routine. Simply run the saw at full throttle for 30 seconds to instantly tune the carburetor to the current ambient temperature, humidity, and fuel quality.

• Ultra-Fast Acceleration Response: Engineered with a specialized lightweight flywheel and crank geometry that achieves 0 To 100km/h throttle response in just 0.25 seconds—matching the acceleration profile of the legendary MS 500i.

• Integrated Plunge-Sight Fan Housing: Molded parallel sight lines on the starter casing provide a 1:1 visual vector with the guide bar centerline, enabling absolute directional precision during complex plunge cuts and directional felling.

• Ematic™ Controlled-Delivery Oil Pump: Features an adjustable variable-displacement oiler with an “E-Mode” setting that reduces chain lube consumption by up to 50% while allowing manually boosted flow for dry or thick timber.

• HD2 PET Radial Air Filter Array: Upgraded with pre-separation air routing and an ultra-fine HD2 PET filter (70% finer pores than polyamide filters) to completely seal the engine intake against fine wood dust, extending service intervals up to 5x.

• Vibration-Isolated Ergonomic Chassis: Utilizing 4-point steel spring buffers that isolate handle movement, reducing hand-arm vibration values to a low 3.3 m/s², preventing fatigue during continuous 8-hour commercial shifts.

• Captive Sprocket Cover Nuts: Prevents lost hardware during field maintenance or chain changes in thick underbrush—the mounting nuts remain permanently attached to the chain sprocket cover.
