Description
The Husqvarna K 770 is a powerful all-round power cutter with features that make it one of the best power cutters on the market. Equipped with semi-automatic SmartTension™ system allows for optimal power transmission, minimum wear and maximum belt life. The light weight, outstanding power-to-weight ratio, the reliable start and exceptionally low vibrations mean less strain and maximized productivity. Suitable for road work and easy to cut in a straight or curved track or close to sidewalk when used with KV7 trolley. *Blade not included as standard 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.
