Husqvarna K770 12” OilGuard Disc Cutter – 2-Stroke - Code 967808801

Ever had engine trouble caused by the wrong oil-fuel mix or oil type? Our unique OilGuard technology will help you prevent the damage from this. An optical detection system guards your machine, and reduces the revs per minute if something is wrong, saving you maintenance costs. Perfect for the rental industry.

Features

  • OilGuard - The unique optical detection system prevents engine damage caused by the wrong fuel-oil mix or incorrect oil type.
  • Possible to deactivate the OilGuard function - Allows the use of standard two-stroke oil by simply pulling out the OilGuard button on the rear handle.
  • Easy and optimal belt tensioning - The semi-automatic SmartTension™ system minimises the risk of under- and over-tensioning the drive belt.
  • Light and powerful - Lightweight, compact design delivers a superior power-to-weight ratio for easier handling and high cutting performance.
  • Exceptionally low vibrations - Vibrations below 2.5 m/s² in the handles improve operator comfort and reduce fatigue during extended use.
  • Long service intervals - The Poly-V belt, DuraStarter™, and Active Air Filtration™ system reduce maintenance requirements and extend service life.
  • Heavy-duty cutting arm - A cast magnesium crankcase with a three-bolt joint provides greater rigidity and durability.
  • Easy to start - Air purge, decompression valve, and digital ignition system ensure quick and reliable starting.
  • Less slurry and low water consumption - Progressive water valve provides precise water flow for effective dust suppression while reducing water usage.
  • Cuts close to walls or ground - The reversible cutting arm allows cutting close to walls, kerbs, and ground level.
  • Blade shaft and bearings - Designed to extend blade life and reduce maintenance requirements.
