Husqvarna K770 Oilguard Petrol Disc Cutter

The Husqvarna K770 OilGuard is even more advanced than the very popular K760 Oilguard model. The principle of the OilGuard technology is that the machine detects whether there is enough oil in the system. A special pigment in the oil is picked up by the sensor and it goes into limp mode if the quantity or type of oil isn't sufficient.

Husqvarna's K760 Oilguard has gained a reputation for quality and reliability and this new K770 OilGuard model has some incremental improvements which raise the bar even higher. With an improved digital ignition, stronger cutting arm and a dynamic belt tensioning system, this market-leading power cutter is outperforming its predecessor.

If you've had engine trouble caused by the wrong oil-fuel mix, then Husqvarna's OilGuard models are for you. An optical detection system puts the machine into maintenance mode and reduces the revs per minute if the wrong type or amount of oil is detected. This can help prevent damage and save maintenance costs.

The Husqvarna K770 features a number of incremental improvements over its predecessor, and the Oilguard version carries this pattern forward with the most reliable flagship disc cutter they have ever developed.

Husqvarna's most efficient disc cutter to date has a very low Hand Arm Vibration (HAV) rating of 2.5 m/s² and a reduced slurry production when wet cutting.

The new K770 OilGuard comes with a 12" Husqvarna Tacti-Cut S50 blade which has a RRP of £38.00 (+VAT).

The 14" saw package contains a 14" Husqvarna Tacti-Cut S50+ with a list price of £88 (+VAT)!
