  Oilguard

  The optical detection system detects if there is oil in the fuel or if the oil type is wrong.

  Possible to de-activate the OilGuard function

  You can use standard two-stroke oil by deactivating the OilGuard function, simply pull out the OilGuard button by the rear handle.

  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 DuraStarter™ and efficient filter-system Active Air Filtration™ ensure 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 carburetor, 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 stepless adjustment.

  Fits multiple blade bushings

  Blades with 20mm and 25.4mm bore can be fitted thanks to the reversible blade bushing.

  Less emissions and fuel consumption

  Our X-Torq® engine produces less emissions, has lower fuel consumption and results in more power.

  Blade Shaft And Bearings

  Provide extended blade life and reduces maintenance.

  Maintenance-free starter

  Patented, dust sealed starter unit with a sealed return spring and pulley bearing. DuraStarter™ also includes a starter cord with greatly increased durability. This makes the starter virtually maintenance free, further enhancing 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 etc, reducing wear.

  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. To provide the user a comfortable operating position reduced strain, the distance between the handles is large. 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.

  EasyStart

  EasyStart ensures easier starting by reducing the compression in the cylinder.

  Poly-V belt

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