Product information & specifications
STIHL MS 300 C-M Professional Petrol Forestry Chainsaw - 53.2cc 3.3 kW MS 261 Replacement
The STIHL MS 300 C-M is the direct replacement for the STIHL MS 261 C-M — a completely redeveloped professional petrol forestry chainsaw delivering 53.2 cc displacement, 3.3 kW power and 15% more torque than the MS 261 C-M, in a compact body weighing just 4.8 kg without fuel, bar or chain. Designed for foresters, arborists and land management professionals who fell and process small to medium-sized trees daily, the MS 300 C-M combines M-Tronic 3.0 fully electronic engine management with the fuel-efficient 2-MIX engine for fast acceleration, easy starting and consistent power delivery across a full working day. Low gyroscopic forces, a compact body and improved rear handle geometry make felling, limbing, snedding and plunge cutting more comfortable and controlled.
Key Features
- 53.2 cc 2-MIX engine, 3.3 kW — more displacement and more power than the MS 261 C-M in a lighter, more compact body
- 15% more torque than MS 261 C-M — helps the saw hold cutting speed in thicker wood with less risk of bogging down mid-cut
- 4.8 kg powerhead weight — lighter than the MS 261 C-M despite the larger engine displacement and power output
- M-Tronic 3.0 engine management — fully electronic control of ignition timing and fuel metering, taking account of temperature, altitude and fuel quality, with no manual carburettor adjustment
- Rapid chain acceleration — comparable with the fuel-injected MS 500i, taking the chain from 0 to 100 km/h in 0.25 seconds
- Low gyroscopic forces and compact body — improved handling balance and manoeuvrability during felling, limbing, snedding and plunge cutting
- Vertical felling line — guides accurate directional felling cuts
- Parallel plunge-cutting direction lines on fan housing — set at 90° to the felling line to show cutting direction and depth during bore and plunge cuts
- Long-life HD2 air filter system — pre-separation plus an HD2 filter extends filter service life and reduces maintenance downtime
- 50% fuel level marker — fast visual indication of when a refill is needed
- Optimised rib pattern on underside of powerhead — helps the saw glide along the trunk during snedding and reduces dirt build-up, making it easier to clean
- Easy-access adjustable oil pump — oil flow adjusted with a standard combination tool, working with the STIHL Ematic system to cut chain oil consumption by up to 50%
- Wide knee support and STIHL anti-vibration system — more comfortable handling across long working days
- Side-mounted chain tensioning and captive sprocket cover nuts — quick, protected chain adjustment and no lost nuts during bar and chain changes in the field
M-Tronic 3.0 and the 2-MIX Engine - What They Mean in Practice
M-Tronic 3.0 is STIHL's fully electronic engine management system. Rather than relying on a manually adjusted carburettor, it regulates ignition timing and fuel metering in all work situations, taking account of temperature, altitude and fuel quality. The practical result is that the MS 300 C-M gives you the best performance from the outset, starts easily in cold and warm conditions, and does not need seasonal or altitude-based carburettor adjustments.
2-MIX is STIHL's low-maintenance 2-stroke engine technology, run on a petrol and engine oil mixture. Four overflow channels guide the fuel-and-air mixture into the cylinder in a targeted, more compressed way, so the fuel burns more completely. The result is lower fuel consumption and lower exhaust emissions than a conventional 2-stroke, while the engine complies with the EU Stage V emissions directive and keeps its strong power-to-weight ratio.
MS 300 C-M vs MS 261 C-M - Key Improvements
The MS 300 C-M has been completely redeveloped for the professional 50cc class. Here are the key differences for existing MS 261 C-M users.
| Feature | MS 261 C-M | MS 300 C-M (replacement) |
|---|---|---|
| Displacement | 50.2 cc | 53.2 cc - 6% larger |
| Power output | 3.0 kW | 3.3 kW |
| Torque | Baseline | +15% - holds cutting speed better in thicker wood |
| Weight (powerhead) | 4.9 kg | 4.8 kg - lighter despite larger displacement |
For current MS 261 C-M users the upgrade case is straightforward: more power, more torque and a slightly lighter body in a directly comparable professional package, with the added handling and maintenance features listed above.
Important Use Guidance
Professional chainsaw PPE is required at all times. The MS 300 C-M is a professional-grade petrol chainsaw. Use requires certified chainsaw protective trousers (EN ISO 11393-2), chainsaw boots, a helmet with integrated face shield and hearing protection, and chainsaw gloves appropriate to the application. At 104 dB(A) sound pressure, the MS 300 C-M requires hearing protection rated for this exposure level on every use.
Vibration levels of 3.5 m/s² on the left handle and 4.2 m/s² on the right. Professional operators should be aware of daily vibration exposure limits under the Control of Vibration at Work Regulations 2005. The EAV (Exposure Action Value) is 2.5 m/s², and the ELV (Exposure Limit Value) is 5 m/s². Track daily usage time against vibration exposure and rest hands and arms appropriately.
M-Tronic 3.0 does not require manual carburettor adjustment — the system manages this automatically. Follow the STIHL manual for M-Tronic operation and starting procedures.
Also Known As
The STIHL MS 300 C-M is also referred to as the STIHL MS 300, MS300 C-M, STIHL 300 chainsaw, STIHL 53cc chainsaw and MS 261 replacement chainsaw. The "C-M" designation identifies the captive sprocket cover nut ("C") and M-Tronic electronic engine management ("M"). An MS 300 C-M VW variant with heated handles is also available.
Pairs Well With
- STIHL 2-Stroke Oil (HP Super) — the recommended oil for the MS 300 C-M's 2-MIX engine, mixed at 50:1
- Chainsaw Protective Trousers — EN ISO 11393-2 certified leg protection required for all chainsaw operation
- Chainsaw Helmet Systems — integrated face, visor and hearing protection for the MS 300 C-M's 104 dB(A) sound pressure level
- Sharpening and Maintenance Tools — keep chains sharp and the HD2 filter clean to maintain the MS 300's performance between service intervals

FAQs
Does the MS 300 C-M directly replace the MS 261 C-M?

What is M-Tronic 3.0?
M-Tronic 3.0 is STIHL's fully electronic engine management. It regulates ignition timing and fuel metering in all work situations, taking account of temperature, altitude and fuel quality, so no manual carburettor adjustment is needed.
What is the vibration level of the MS 300 C-M?
3.5 m/s² on the left handle and 4.2 m/s² on the right. Professional operators should track daily vibration exposure against the Control of Vibration at Work Regulations 2005 EAV (2.5 m/s²) and ELV (5 m/s²) and manage working time accordingly.
What is the 2-MIX engine and why does it matter?
2-MIX is STIHL's low-maintenance 2-stroke technology. Four overflow channels guide the fuel-and-air mixture into the cylinder so it burns more completely, cutting fuel consumption and exhaust emissions while keeping high power. It complies with EU Stage V.
