HIGH ENGINE EFFICIENCY
Könner & Söhnen gasoline chainsaw engines are known for their high reliability and resistance to wear, ensuring a long service life. The four-channel fuel supply system ensures optimal mixing of the fuel-air mixture for the most efficient combustion, which reduces harmful substances in the exhaust gases and maximizes fuel efficiency.

EASY START SYSTEM
The easy-start system is a modern technology that significantly simplifies the engine starting process, making it more comfortable and faster. It consists of several elements: a manual fuel pump (primer), a starter with an additional spring, and an automatic START button. The manual fuel pump (primer) enables faster fuel supply to the carburetor, significantly reducing the number of starter pulls and extending its lifespan. The manual starter is equipped with an additional spring that ensures quick and easy starting without effort. The chainsaw stop button automatically returns to the START position. Thanks to this feature, the chainsaw is always ready to start, enabling you to focus on your work without being distracted by minor details.

AUTOMATIC CHAIN LUBRICATION
Könner & Söhnen® chainsaws are equipped with a modern automatic chain lubrication system. During operation, the built-in oil pump evenly supplies the necessary amount of lubricant to the bar and chain, ensuring reliable and continuous lubrication for optimal performance. Depending on the length of the guide bar and the type of wood, the function of adjusting the oil supply in the oil pump enables you to reduce costs.
SIDE CHAIN TENSIONING
The side access chain tensioning system makes chain tension adjustments more convenient and safer, saving time and energy.

TOP-LEVEL PROTECTION
Könner & Söhnen® gasoline chainsaws are equipped with built-in safety features. The inertia chain brake automatically activates upon kickback and immediately stops the chain. A spiked bumper firmly holds the wood during cutting, ensuring stable and safe operation. A chain catcher is designed in case the chain slips off or breaks. It catches the chain, preventing injuries and accidents. The throttle trigger lock prevents the trigger from being accidentally pulled while moving the chainsaw.

ANTI-VIBRATION SYSTEM
Reducing the level of vibration transmitted from the engine to your hands enhances work comfort and decreases fatigue. You can work longer without breaks, increasing productivity.

FLEXIBILITY IN CHOOSING COMPONENTS
Depending on the diameter and type of wood to be cut, you can choose the appropriate bar and chain length for efficient operation. Bars and chains from Könner & Söhnen® and Oregon are available.

RUBBER COATING ON THE HANDLE FOR A COMFORTABLE GRIP
A special rubber coating on the rear handle ensures a secure grip and confident control of the chainsaw.
ROUND HANDLE
The bow-shaped handle on the chainsaw is an important feature that significantly enhances convenience, enabling you to easily choose any cutting angle and switch from vertical to horizontal cuts with exceptional precision.
