EQUIPMENT

Stihl quick chain tensioner
CHAIN TENSIONING WITHOUT TOOLS. Thanks to the STIHL quick chain tensioner, it is possible to tension the chain quickly and without tools using the dedicated adjustment knob. Turning it to the left loosens the chain, while turning it to the right tightens it. Furthermore, after tightening the sprocket cover, the guide bar locks automatically.

Stihl ErgoStart system
EASY STARTING. Thanks to the STIHL ErgoStart system, starting motorized tools is made easier. Simply pull the starter rope steadily and evenly. The pull speed of the starter rope is significantly reduced, and the engine starts quickly and reliably even at low speeds. This is made possible by the presence of an additional spring between the crankshaft and the starter pulley.

Manual fuel pump
FEWER STARTING ATTEMPTS. The manual fuel feed pump reduces the number of starting attempts by speeding up the process. This is especially useful after long breaks in work. For this purpose, it is recommended to operate the pump several times before starting. This ensures a sufficient amount of fuel is supplied to the carburetor during startup.

Compensator
REDUCED MAINTENANCE. By compensating pressure, a regulation system inside the carburetor called the compensator ensures that despite increased air filter contamination, engine power, exhaust gas quality, and fuel consumption remain almost constant for a long time. Therefore, the air filter only needs to be cleaned when there is a noticeable drop in performance. This allows for extended work periods without maintenance.

Oil/Chain Tank Cap
EASE AND SPEED OF OPENING AND CLOSING. Thanks to the cap that can be opened and closed without the use of tools, it is possible to open and close the oil and fuel tanks in a few simple steps thanks to the bayonet closure.

Stihl 2-Mix Engine
PARTICULARLY ENERGY EFFICIENT. Thanks to the STIHL 2-Mix engine, it is possible to reduce not only exhaust gas pollution but also consumption and the resulting operating costs. This 2-stroke engine requires little maintenance and uses fuel efficiently even at high performance. The fuel consists of a mixture of gasoline and engine oil. The STIHL 2-Mix engine complies with the strict European Stage V emission directive.
