Durable, high performing farm saw
STIHL 2-MIX reduced-emission engine technology :
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.

Advanced combustion technology
Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum
combustion and highly efficient performance. The result is lower fuel consumption
and high torque across a broad rpm range.

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.

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.

Compensator:
CLICK HERE TO ENLARGE
The STIHL compensator, a control system in the carburettor, ensures
that despite increasing pollution of the air filter engine performance, exhaust
quality and fuel consumption over a long period remain almost constant.
Only when a noticeable performance degradation occurs,
the air filter must be cleaned. So, very long working
intervals without maintenance are possible. (Similar to picture)

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%

The functions of the machine, such as cold and warm startup,
operation and stop, are controlled by a single lever. This makes
the operation especially comfortable and safe, because the right hand
on the handle can remain. (Similar to picture)

HD2 filter :
CLICK HERE TO ENLARGE
The newly developed HD2 filter is made from polyethylene filter material with up to 70%
finer pores than fleece and polyamide filters to trap even very fine dust. In addition, it is
oil and water-repellent and thus very easy to clean. The PET-covered round filter cartridge
with quick-release lock enables the filter to be assembled and disassembled in next to no
time, without using tools
