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: K 770

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.

Optimized engine performance

Optimized 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.

Blade retarder

Reduces the stop time of the blade when the machine is switched off, which enables you to quickly move on to the next job.

Maintenance-free starter

Patented, dust-sealed starter unit, seals the return spring and the pulley bearing. This makes the starter virtually maintenance free further boosting the reliability of our cutters.

Reduced wear

Reduced wear thanks to the drive belt with fully sealed transmission, which keeps out the cutting dust.

Cuts close to walls or ground

The cutting arm is reversible which lets you cut closer to walls or the ground. The drive belt has a fully sealed transmission. This keeps out cutting dust, reducing wear on the belt.

Active Air Filtration™

Our two-step filtration system with centrifugal cleaning and a single paper filter increases product life and extends service intervals.

Anti-vibration system

Our anti-vibration system reduces vibrations in the cutter handles, so they are more comfortable to hold and can be used for longer periods. The distance between the handles is large to enable the user a comfortable operating position and to reduce strain. The handles and the short engine body mean the user always stands close to the machine, for easier handling and control.

DuraStarter™

Our virtually maintenance free starter, thanks to the dust-sealed starter and the durable starter cord.

Poly-V belt

Provides better transmission of power, less frequent re-tensioning and extended service intervals.

SmartCarb™

Our built-in automatic filter compensation maintains high power during the air filter life time.
