X-Torq® engine technology
The X-Torq® engine design reduces harmful exhaust emissions by up to 75% and increases fuel efficiency by up to 20%.
Magnesium crankcase
Sturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life.
AutoTune™ II
10 times quicker air/fuel mix adjustment with AutoTune™ II ensures a correctly tuned engine setting and optimised engine performance in all conditions.Automatically compensates for different fuels, altitudes, humidity, temperature and dirt in the air filter.
Adjustable oil pump
Adjustable oil pump makes it easy to set the chain lubrication according to your needs.
Air Injection™
Advanced centrifugal air cleaning system which removes the majority of dust and woodchips before it enters the air filter, resulting in smoother operation, longer intervals between filter cleans & reduced wear on the engine.
Better chip ejection
The clutch cover is designed to optimise rapid, safe saw chip ejection. Prevents clogging, even when cutting long fibre wood
Soft cut-out system
The innovative system for engine control is designed for providing a long engine life. The system monitors the engine and assures that the engine always is protected from over-revving.
Easy refuelling
The flip-up tank cap is easy to open and close when refuelling, while the transparent fuel indicator makes it easy to check fuel level.
