Husqvarna K770 12" (300mm) Cut Off Saw

Stock Code: SE00011

Product Description

The Husqvarna K770 is equipped with a semi-automatic SmartTension™ system which allows for optimal power transmission, minimum wear and maximum belt life.

Husqvarna’s K770 is light weight, with outstanding power-to-weight ratio. The reliable start and exceptionally low vibrations mean less strain and maximised productivity.

Suitable for road work and easy to cut in a straight or curved track or close to pavement when used with KV7 trolley.

Digital Ignition with Optimised Timing

A powerful spark enables easy starting and efficient combustion with optimized engine timing. DuraStarter™ is dust-sealed with a durable starter cord, making it virtually maintenance-free. The unique design of the carburettor, cylinder and digital ignition system, together with air purge and decompression valve ensure an easy start

Heavy-duty Cutting Arm

The three-bolt joint which attaches to the cutting head enables higher torsional rigidity, and the crankcase is made from cast magnesium. Previous cutting arms had just two bolts.

Easy and Optimal Belt Tensioning

Risk of under-tensioning and over-tensioning is minimised thanks to Husqvarna's semi-automatic SmartTension system. This helps to maximise the life of the belt and minimise mechanical wear and abrasion.

Light and Powerful

This compact and lightweight machine retains its performance, producing a superb power-to-weight ratio. This gives you more efficiency so you can cut more and earn more. The blade is quicker to stop spinning when you switch the machine off, which is safer and means you can quickly proceed with the next task.

Long Service Intervals

The maintenance-free starter, strong Poly-V belt and efficient filter-system ensure long service intervals an minimal downtime. The operating temperature inside the belt cover is kept low thanks to the new clutch cooling fan. The new belt has a less frequent need for re-tensioning. Find out more about servicing your K770

Maintenance-free Air Filter

The two-step filtration system with centrifugal cleaning and a single paper filter increases product life and extends service intervals. The only time the filter needs to be checked and changed is if you experience lack of power, and the inherent filter compensation maintains high power during the lifetime of the air filter.

Less Slurry and Low Water Consumption

The efficient wet cutting kit provides excellent dust control. You can efficiently reduce slurry by binding the dust thanks to the progressive water valve which exactly adjusts the feed of water.

Less Emissions and Fuel Consumption

Husqvarna's X-Torq® engine helps to lower fuel consumption, reduce emissions and increase power. The built-in SmartCarb™ automatic filter compensation maintains high power and lowers fuel consumption.

Anti-vibration System

Reduced vibrations in the handle of the cutter means you can operate comfortably for longer. HAV ratings are below 2.5 m/s².
