Suitable for road work and easy to cut in a straight or curved track or close to sidewalk when used with KV7 trolley
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
Efficient power performance – Our X-Torq® engines deliver great power and torque thanks to highly efficient combustion
Smooth blade stop – Reduces the stop time of the blade when the machine is switched off, which enables you to quickly move on to the next job
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 – Reduced vibrations in the cutter handle for more comfort and longer operation periods
