Husqvarna K770 Vac

The Husqvarna K770 Vac is new for 2019 and offers a new way to deal with concrete dust while cutting. Innovative developments allow a H-class dust extractor to be connected directly to the rear of the saw. The front guard has a retractable lower cover to help manage suction of silica dust and other particulates. The lower section automatically folds back, so there is no extra activity for the user to undertake.

The K770 Vac provides the same reliable cutting as the regular K770. While it is only available in 300mm, the blade is held forwards of the guard allowing a cutting depth of 122mm. This is close to the 125mm which is achieved by a 350mm K770.
It is vital to control concrete dust in order to protect both site and operators. While the K770 Vac will work with more commonly used M-class dust extractors, these are not recommended when working with concrete dust. The particulates are finer than the dust generated when working with wood and metal. M-class dust extractors also fail to provide the needed protection when emptying or changing bags. An H-class dust extractor such as the Husqvarna S26 will give the K770 Vac all the suction it needs, while keeping the dust sealed with H13 filters.
Traditionally dust generated wile cutting was controlled using water. While that is still an option, it is becoming less economical. Slurry also has to be managed and disposed of correctly. Dry dust can be sealed in a LongoPac bag and disposed of far more efficiently. Wet cutting is also unsuitable for many locations due to the damage it can cause to the surrounding area, not to mention the residue build up on machines.
The K770 Vac is a sensible and effective solution to dust control while cutting, which also provides deep cuts and reliable production rates.

Husqvarna K770 – The Latest Innovation in Concrete Cutting

The Husqvarna K770

Husqvarna K770

The new Husqvarna K770 is Husqvarna’s latest concrete saw, available from late May 2018. With a lineage stretching back to 1958, Husqvarna have proven their expertise in concrete tooling and cutting. Here at Findasaw we have sold and championed the K760 ever since we opened. It has easily been our best-selling disc cutter by a wide margin. The new Husqvarna K770 improves on the previous design, using input taken from users around the world to build a better machine. Instead of redesigning the wheel, Husqvarna have taken the proven qualities of the K760 and built on them. This has allowed them to meet user’s needs, improving the ignition and cutting arm.

K770 Key Improvements

  • A redesigned, magnesium cast, heavier cutting arm with a three-bolt joint enables higher torsional rigidity, helping to further stabilise cutting.
  • Digital ignition with optimised timing provides a powerful spark at precisely the right time, enabling an easy start and efficient combustion.
  • A new clutch cooling fan keeps the temperature inside the belt cover lower, improving the life of transmission components and the belt.
  • SmartTension™ keeps the drive belt correctly tensioned, providing optimal power transmission and prolonging the life of the belt.

The Husqvarna K770 provides the same high build quality as its predecessor. Using components that will stand up the the stress and rigour of cutting through some of the hardest materials used in construction. Like the K760 before it, the K770 comes in both 300mm and 350mm versions. This give you a cutting depth of 100mm and 125mm respectively. There is also the option to invest in Oil Guard versions. Oil Guard protects the disc cutter from damage caused by incorrect fuel/oil mix. For road cutting, the K770 can be used with the KV7 Trolley, so you can keep your lines straight and vastly improving the stability of your concrete cutting.
