EQUIPMENT

Long-life air filter with pre-filtration
This innovative system allows for a significantly longer filter lifespan. Thanks to the pre-filtration, it removes coarser dirt particles, reducing the workload of the actual filter. The chainsaw can operate longer without needing filter cleaning compared to a chainsaw without this type of filter

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. In an instant, the PET-coated filter core can be assembled and disassembled without the use of tools

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

ElastoStart
Thanks to the exclusive STIHL ElastoStart starting handle, combined with the manual fuel pump and the decompression valve, kickback during ignition is significantly reduced

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

Anti-vibration system
Special damping zones placed with precision reduce the transmission of vibrations from the engine and chain to the handle and grip

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

Side chain tensioner
The chain is tensioned laterally via the sprocket. This avoids 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 flow oil pump allows precise regulation of the oil flow rate according to needs. It is possible to reduce the amount of supplied oil by up to 50%

Kombi lever with stop button
The lever automatically returns to the operating position (I) after stopping

Decompression valve
The decompression system automatically opens the intake valve. This absorbs pressure peaks and reduces the amount of force needed on the starter rope

STIHL Injection (i)
The injection technology is characterized by extremely simple use. Goodbye to the combined lever, only the stop button remains for shutdown. The fully electronic engine management and the sensor-supported electronic control system ensure optimal engine power and consistent acceleration in every operating condition. Real-time measurement allows the tool to calculate the exact amount of fuel and the optimal ignition point. The injection valve injects fuel directly into the space beneath the piston. The unique combination of lightweight design and engine technology offers the best power-to-weight ratio on the market while maintaining a compact structure
