Features
Easy and optimal belt tensioning
The semi-automatic SmartTension minimises the risk of under- and over tensioning
Light and powerful
A light, compact and powerful machine with superior power-to-weight ratio.
Heavy-duty cutting arm
The new-designed cast magnesium crankcase has a three-bolt joint to attach the cutting head, enabling higher torsional rigidity than the previous two-bolt solution.
Long service intervals
A strong Poly-V belt combined with our maintenance-free starter DuraStarter™ and efficient filter-system Active Air Filtration™ ensures long service intervals.
Digital ignition with optimised timing
Provides a powerful spark with optimized timing, enabling easy start and efficient combustion.
Exceptionally low vibrations
Vibrations below 2.5 m/s2 in the cutter handles for more comfort and longer operation periods.
Easy to start
The unique design of the carburettor, cylinder and digital ignition system, together with air purge and decompression valve ensure an easy start.
Maintenance-free air filter
The only time the filter needs to be checked and changed is if you experience lack of power.
High power with less fuel
Our built-in automatic filter compensation SmartCarb™ maintains high power and lowers fuel consumption.
Optimised engine performance
Optimised engine performance through efficient cylinder design, digital ignition system and X-Torq engine technology.
Less slurry and low water consumption
Excellent dust control with our wet cutting kit. A progressive water valve for exact adjustment of the water volume to efficiently bind the dust and reduce slurry.
Easy to change blade guard position
The light magnesium blade guard facilitates cutting, thanks to its step-less adjustment.
Fits multiple blade bushings
Blades with 20mm and 25.4mm bore can be fitted thanks to the reversible blade bushing.
DualCharge™
New DualCharge™ engine technology provides more power, lower fuel consumption and greatly reduced emissions.
