STIHL MS 231

14/16″ Bar Supplied – 40.6cc Engine – 2.7HP

The STIHL MS 231 chainsaw is a compact saw with up to 20% less fuel consumption and up to 70% fewer emissions compared to its predecessor.

The MS 231 chainsaw has excellent power to weight ratio and makes it ideal for farmers, felling small trees and firewood.

Very comfortable to operate with the STIHL anti-vibration system and well balanced. Little maintenance required due to the STIHL pre-separation air filter system which effectively reduces saw dust getting to the air filter by 90%.

Available in 14 or 16 inch bar.

Displacement 40.6 CC

Power output 2.7 HP

Weight 4.9 KG

Standard features:

Reduced-emission engine technology:

2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

Anti-vibration system:

Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine’s engine are dampened which significantly reduces vibrations at the handles.

Pre-separation air filtration system:

STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.

Compensator:

This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn’t need to be cleaned until an appreciable drop in power occurs.

Single-lever master control:

All important functions such as start, choke, throttle and stop are operated via a single lever. Side chain tensionerZoom Side chain tensioner The tensioning screw can be found on the side of the chain saw through the sprocket cover. This removes the need for contact with the sharp saw chain.

Ematic chain lubrication system:

The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.

Tool free filler caps: Special catches on the fuel and oil tanks for easy opening and locking without the need for tools
