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

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.
