Standard Features

HD2 filter with radial seal

The new HD2 air filter, made from PET material and featuring a radial seal, prevents the intake of fine dust particles. The hermetic seal increases the service life of the engine and reduces wear.

Decompression valve

The decompression valve is part of the easy start-system. The valve should be pressed before starting in order to reduce the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic, meaning that it must be pressed manually before starting, but then closes automatically.

STIHL M-Tronic (FT)

For a cold start, the STIHL M-Tronic only needs one start position on the combi-lever. After starting, you can immediately power up to full speed. The amount of fuel required is precisely calculated by the system and supplied as needed. Otherwise, start in position I as usual.

STIHL anti-vibration system

Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.

Compensator

This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.

Captive bar nuts

Bar nuts held captive in the sprocket cover will not get lost when changing over the cutting attachment.

Controlled-delivery oil pump

The exact chain oil output can be adjusted maunally for varying conditions, allowing for a reduction of up to 50%.

QuickStop Chain Brake

The QuickStop chain brake is a protective mechanism when handling chainsaws. The chain brake is operated via the front hand guard and brings the saw chain to a standstill in fractions of a second. If the kickback is strong enough, the Quick Stop Chain Brake automatically releases.

Side-mounted chain tensioning

The tensioning screw is located on the side of the chain saw through the sprocket cover. Chain side tensioning allows the saw chain to be retensioned effortlessly, avoiding any contact with the sharp chain.

STIHL Ematic with new oil pump system

The new oil pump system allows a higher volume of oil to be delivered. This is especially useful in dusty conditions or when using a long guide bar.

STIHL ElastoStart

STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the users joints and muscles through a spring or rubber element in the starter handle

Tool free fuel caps

Special caps on the fuel and oil tanks are designed for easy opening and locking without the need for tools.
