Inertia Chain Brake
Effective inertia-activated chain brake
Air Injection
Extends the interval between filter cleaning, improving efficiency and increases engine life.
Two Mass Principle
Effectively minimising vibrations by isolating the engine from the handles reducing operator fatigue.
Smart Start®
The engine and starter have been designed so the machine starts quickly with minimum effort. Resistance in the starter cord is reduced by up to 40%.
Quick-release Air Filter
Facilitates cleaning and replacement of the air filter.
Felling Marks
Distinct and coloured felling marks for better felling precision.
Three-piece Crankshaft
Forged three-piece crankshaft giving maximum durability for the toughest applications.
Adjustable Oil Pump
Adjustable oil pump allows you to adjust chain lubrication to suit all working applications.
Ergonomic Handles
Angled front handle allows the operator to work in a natural working position reducing fatigue.
Magnesium Crankcase
Sturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life.
