EQUIPMENT

STIHL 2-MIX Engine
The two-stroke engine with STIHL 2-MIX technology enables fuel savings of up to 20% and a reduction of harmful emissions by up to 70% compared to STIHL two-stroke engines of the same power without 2-MIX technology

HD2 Filter

The new HD2 filter with polyethylene filter material has pores 70% finer than felt and polyamide filters, allowing it to filter even the finest dust particles. Additionally, it is oil-repellent, making it easy to clean. The PET-coated filter core can be mounted and removed in no time without the use of tools

Decompression Valve
The decompression system automatically opens the intake valve. In this way, pressure peaks are absorbed and the amount of force required on the starter rope is reduced

STIHL ElastoStart
Thanks to the exclusive STIHL ElastoStart starter handle, combined with the manual fuel pump and decompression valve, kickbacks during ignition are significantly reduced

Side chain tensioner
The chain is tensioned laterally via the sprocket. This prevents any contact between the operator’s hand and the sharp chain

Adjustable oil pump
Different cutting lengths, wood types, and working techniques require varying amounts of oil. The adjustable oil pump allows precise regulation of the oil flow according to needs. It is possible to reduce the oil supply by up to 50%

Tool-free tank cap
Special caps for the fuel tank and oil tank allow for easy opening and closing without difficulty

Long-life air filter with pre-filtering
When cleaning the combustion chamber, a cushion of clean air is interposed between the exhaust gases and the fresh mixture coming from the crankcase, reducing fuel-containing air losses and thus lowering harmful emissions for humans and the environment

Anti-vibration system
Special damping zones precisely positioned reduce the transmission of vibrations from the engine and chain to the handle and grip

Single-lever control
The M-Tronic system can be started cold. The control of all functions such as starting, operation, and stopping can be performed with one hand

Compensator
Allows a constant fuel-air mixture even when dirt increases in the air filter

Anti-loosening nuts
When mounting the chain sprocket cover, the nuts are always correctly positioned, with no risk of tilting – only a few adjustments are needed. Each nut can be tightened independently of the others

Ematic chain lubrication system
Depending on the type of guide bar and wood, the STIHL Ematic system reduces chain oil consumption by up to 50%. It consists of an Ematic guide bar, Oilomatic chain, and an oil pump with adjustable and reduced flow. The lubricant is thus delivered precisely and with minimal loss exactly where it is needed

STIHL 1-in-4 port technology
1-in-4 channel technology – high torque across a wide range of speeds

Electric carburetor heating
The carburetor heating, which switches on and off according to temperature, prevents the carburetor from freezing during winter use

Magnesium piston
The magnesium piston combined with the consistent and lightweight design results in some real strengths. Excellent power-to-weight ratio.
