Key Features & Benefits
Advanced Cooling System for Longer Engine Life
The optimised cooling design ensures dependable operation in demanding conditions, protecting the engine during continuous, high-RPM professional use.
High-Visibility, Long-Lasting Felling Sight
Built to outlast the saw itself, the durable felling sight supports precision cutting, improving accuracy for professional tree felling.
Retained Bar Nuts
Prevents bar nuts from loosening or disappearing during maintenance—ideal for forestry and field environments.
LowVib® Anti-Vibration Technology
Specially designed dampeners significantly reduce vibration, minimising fatigue and protecting arms and hands during long working hours.
Slim, Ergonomic Chainsaw Body
A streamlined, slender design enhances balance and control, making the saw easier to handle during limbing, bucking, or working in tight spaces.
Air Injection™ – Extended Filter Life
The centrifugal air-cleaning system removes debris before it reaches the filter, resulting in reduced wear and longer operating time between air filter cleanings.

Quick-Release Air Filter
Fast access to the air filter enables quick cleaning and minimal downtime on job sites.

AutoTune™ Automatic Engine Setting

X-Torq® Engine Technology
Reduces fuel consumption and emissions while maintaining high torque and excellent cutting performance. Compliant with global environmental standards.
Visible Fuel Level
Transparent fuel indicator makes monitoring fuel quick and easy.
Forged Three-Piece Crankshaft
