EQUIPMENT

Long-life air filter with pre-filtration

This innovative system allows for a significantly longer filter lifespan. In fact, thanks to the pre-filtration, it removes coarser dirt particles, reducing the workload of the actual filter. The chainsaw can operate longer without needing the filter to be cleaned compared to a chainsaw without this type of filter.

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

STIHL 2-MIX engine
The STIHL 2-MIX engine is powerful and economical at the same time. The separation of exhaust gases from inert gas minimizes unburned particle emissions, increasing performance and saving fuel.

Compensator
Ensures a constant fuel-air mixture even when the air filter becomes dirtier.

QuickStop Chain Brake (Q)
Special precisely positioned damping zones reduce the transmission of vibrations from the engine and chain to the handle and grip.

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 rate. This ensures the lubricant is delivered precisely and with minimal loss exactly where it is needed.

Anti-Vibration System
Special precisely positioned damping zones 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 for 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 cutting chain.

Single-Lever Control
All functions such as starting, operating, and stopping can be controlled with one hand.
