Husqvarna K 770 VAC is a lightweight power cutter for dry cutting and has the power and all qualities of the standard K 770 while adding the benefit of dust extraction. With an easy to connect 2'' hose dust is effectively transported to an external dust extractor. K 770 VAC has an impressive maximum cutting depth of 122 mm, very close to that of a 14'' machine. Suitable with a Husqvarna S 26 dust extraxtor.

• Easy to connect - The 2'' hose is easely connected to an external dust extractor.
• Effective cutting - The powerful engine paired with the external dust extractor enables superior dry cutting performance.
• Maximised cutting depth - The integrated gearbox, positioning of the pulley and the 60 mm ?ange enables a cutting depth of 123 mm, very close to that of a 14" machine.
• Smart and effective protection - The double foldable protections enable better dust handling and fold into the blade guard during operation.
• 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.
• EasyStart - EasyStart ensures easier starting by reducing the compression in the cylinder.
• 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.
• 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.
• Less emissions and fuel consumption - Our X-Torq? engine produces less emissions, lower fuel consumption and produces more power.
• 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.
• 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.
• 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 - Possible thanks to the reversible cutting arm.
• Anti-vibration system - Reduced vibrations in the cutter handle for more comfort and longer operation periods.
• DuraStarter? - Our virtually maintenance free starter, thanks to the dust-sealed starter and the durable starter cord.
• Poly-V belt - Provides better transmission of power, less frequent re-tensioning and extended service intervals.
• SmartCarb? - Our built-in automatic filter compensation maintains high power during the air filter life time.
• Asphalt - Asphalt cutting in roadworks.
• Blocks, curbstones and pavers - Cutting building blocks, curbstones and garden pavers.
• Burying of cables - Burying of all kinds of cables.
• Floors and walls - Regular cutting in floors and walls.
• Blade Shaft And Bearings - Provide extended blade life and reduces maintenance.
