STIHL MS 311
Standard equipment:

MODERN, VERSATILE 3.1 KW-ROUND SAW

STIHL 2-MIX ENGINE

CLICK HERE TO ENLARGE

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:

In the longer term, strong vibrations at the handle points
of motor equipment can lead to poor circulation in hands and
arms. STIHL has therefore developed a high quality anti vibration system.Motor
devices with AV system, the vibrations generated by the engine and the
working environment, be substantially reduced at the handle points.

CARBURETTOR HEATING:

Carburettor heating
By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins. This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.

LONG TERM FILTRATION SYSTEM WITH PRE-SEPARATION

CLICK HERE TO ENLARGE

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

CLICK HERE TO ENLARGE

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. (Similar to picture)

DECOMPRESSION VALVE

Decompression valve
The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.

TOOL-LESS TANK LID

STIHL EMATIC SYSTEM

CLICK HERE TO ENLARGE

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%

Lateral chain tensioning

CLICK HERE TO ENLARGE

The tensioning screw can be found on the side of chain saw through the
sprocket cover. This removes the need for contact with the sharp saw chain.

STIHL ELASTOSTART

STIHL ElastoStart reduces the shock caused by the compression of the engine
during starting. The compression shock is taken away from the user's joints and
muscles through a spring or rubber element in the starter handle.
