STIHL MS 231 chainsaw

Excellent for sawing firewood and felling trees. Tightening of the blade chain from the side without contact with the sharp chain, air filter system with long service intervals, quick-lock tank caps for easy and safe refueling, economical 2-MIX engine.

Standard equipment

Vibration damping system
A person who is exposed to long-term vibration, for example engine vibration, can suffer from circulatory disorders in the hands and arms. STIHL's highly effective vibration damping reduces the vibration caused by the machine and the cutting device to a suitable level, so that the machine is safe and ergonomic to use.

Single lever operation
All functions; starting, operating and stopping conveniently with one hand from the same lever.

Lateral tensioning of the blade chain
Almost all STIHL chainsaws (with the exception of the MS 170) are equipped with side tensioning of the saw chain, thus avoiding contact with a sharp saw chain. Turn off the chainsaw and loosen the nut of the bite guard. Tighten the saw chain with a screwdriver and carefully test the chain tension on the saw chain. Easy and safe.

Air filter system with long service intervals
Air is sucked into the flywheel and set to spin. Centrifugal force throws larger and heavier dirt directly out of a separate ramp. The air that reaches the air filter is already pre-filtered. In this way, the filter cleaning interval becomes considerably longer.

Compensator
The STIHL compensator monitors the carburettor so that the mixture of fuel and air is always in the optimal ratio, depending on the dirtiness of the filter. The compensator enables low emissions and optimal power. When you notice that the power clearly decreases, it's time to clean the filter. The filter cleaning interval is considerably longer

STIHL Ematic chain lubrication system
Compared to a standard saw blade without the Ematic system, the STIHL Ematic system saves chain oil by up to 50%, depending on the type of wood and the saw chain. The system is compatible with STIHL Ematic or Ematic S blade plate, STIHL Oilomatic blade chain and oil pump. As a result, the chain oil flowing into the groove of the blade plate sticks to the rotating chain without loss.

Quick release tank caps
Patented closing method for fuel and oil tanks. The cap is closed with a bayonet connector, which makes opening and closing the cap really easy, without tools.

Winter/summer position
You can rely on the carburetor of the STIHL chainsaw even in the cold season: Set your chainsaw to the winter position, so that warm air circulates to the carburetor. This prevents the formation of ice in the carburettor. Simple operation helps in summer and winter use.

STIHL 2-MIX engine
The STIHL 2-MIX engine is efficient and at the same time environmentally friendly. The exhaust gas is separated from the unburned gas, which minimizes flushing losses, i.e. the parts of the mixture that get out unburned. This increases power and reduces consumption. Runs on two-stroke fuel.
