Features

• 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.
• Easy and optimal belt tensioning - The semi-automatic SmartTension minimises the risk of under- and over tensioning
• 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.
• Light and powerful - A light, compact and powerful machine with superior power-to-weight ratio.
• Digital ignition with optimised timing - Provides a powerful spark with optimized timing, enabling easy start and efficient combustion.
• Maintenance-free air filter - The only time the filter needs to be checked and changed is if you experience lack of power.
• 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.
• Less emissions and fuel consumption - Our X-Torq® engine produces less emissions, lower fuel consumption and produces more power.
• Reduced wear - Reduced wear thanks to the drive belt with fully sealed transmission, which keeps out the cutting dust.
• Anti-vibration system - Reduced vibrations in the cutter handle for more comfort and longer operation periods.
• SmartCarb™ - Our built-in automatic filter compensation maintains high power during the air filter life time.
• Burying of cables - Burying of all kinds of cables.
• Rails - Rail cutting.
• Exceptionally low vibrations - Vibrations below 2.5 m/s2 in the cutter handles for more comfort and longer operation periods.
• High power with less fuel - Our built-in automatic filter compensation SmartCarb™ maintains high power and lowers fuel consumption.
• Easy to change blade guard position - The light magnesium blade guard facilitates cutting, thanks to its step-less adjustment.
• 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.
• Cuts close to walls or ground - Possible thanks to the reversible cutting arm
• DuraStarter™ - Our virtually maintenance free starter, thanks to the dust-sealed starter and the durable starter cord.
• Asphalt - Asphalt cutting in roadworks.
• Cast concrete - Cutting cast concrete.
• Rescue cutting - Cutting in rescue operations
• 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.
• Optimised engine performance - Optimised engine performance through efficient cylinder design, digital ignition system and X-Torq engine technology.
• Fits multiple blade bushings - Blades with 20mm and 25.4mm bore can be fitted thanks to the reversible blade bushing.
• Maintenance-free starter - Our dust-sealed starter, where the return spring and the pulley bearing are sealed, gives a virtually maintenance free starter. Developed with a durable starter cord.
• Active Air Filtration™ - Our two-step filtration system with centrifugal cleaning and a single paper filter increases product life and extends service intervals.
• Poly-V belt - Provides better transmission of power, less frequent re-tensioning and extended service intervals.
• Blocks, curbstones and pavers - Cutting building blocks, curbstones and garden pavers.
• Floors and walls - Regular cutting in floors and walls.
• Blade Shaft And Bearings - Provide extended blade life and reduces maintenance.
