By changing the chain saw from summer to winter operation, the intake air is pre-heated over the engine fins.
This ensures that the carburettor does not ice up and you can continue working in freezing temperatures.
Advanced combustion technology
Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance.
The result is lower fuel consumption and high torque across a broad rpm range.
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.
STIHL anti-vibration system
Precisely calculated buffer zones minimise the transfer of engine and saw chain vibrations to the front and rear handles.
The chainsaw therefore runs noticeably smoother. This allows the user to save their strength and work longer.
STIHL Ematic System
Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain
lubricant by up to 50 %, depending on the type of wood and the cutting attachment used.
This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump.
As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.
Single-lever master control
All important functions such as start, choke, throttle and stop are operated via a single lever.
Side-mounted chain tensioning
Side-mounted chain tensioning makes it easy to tension the chain safely.
