Product Details

The Husqvarna K770 Oilguard is the new and more advanced replacement for the K760 disc cutter. Powerful and compact, the K770 Oilguard is a great all round cutter, capable of taking on a wide variety of tasks. The K770 Oilguard has a number of built in upgrades compared to the previous K760 model. The cutting arm is better secured and the crankcase is cast magnesium, providing higher torsional rigidity. It is easy to change the blade guard position, thanks to stepless adjustment.

The unique OilGuard technology prevents damage to the saw caused by operators using the wrong fuel mix or oil type. An integrated optical detection system prevents the disc cutter and reduces the revs per minute if something is wrong. This makes the Husqvarna K770 Oil Guard perfect for the rental industry, or for companies that use agency or temporary labourers on projects.

Suitable for both wet and dry cutting, the Husqvarna K770 Oilguard can be used to cut concrete, asphalt, block, curbstone, rails, floors and walls. It can even be used for rescue cutting. With lower fuel emissions than comparable disc cutters, lower vibrations and reduced weight, the K770 Oilguard is built for longer working periods. The blade retarder reduces the stop time of the blade after a cut, while the unique design of the carburettor, cylinder and digital ignition system ensure an easy start, reducing downtime between cuts. The light weight, outstanding power-to-weight ratio, the reliable start and exceptionally low vibrations mean less strain and maximised productivity. The KV7 Saw Trolley can be used turn the K770 Oilguard into a road cutting or floor saw able to cut along both straight and curved tracks.

The Husqvarna K770 Oilguard 350mm/14" disc cutter is available with the option of a Husqvarna TACTI-CUT S50 Plus Blade, or an ELITE-CUT S50 Blade. A water bottle can also be added for wet cutting applications.
