Husqvarna K770 12-14” OilGuard Disc Cutter - 2-Stroke
The Husqvarna K770 OilGuard (OG) is a technologically advanced petrol disc cutter with a unique optical detection designed to prevent engine seizures caused by the wrong oil-fuel mix or oil type.
If you have had a disc cutter seize as a result of poorly mixed or neat fuel being added to a machine, then the Husqvarna K770 OilGuard may just be the machine you have been looking for - it is highly popular with contractors and rental companies alike.
The K770 OilGuard is available with a choice of 12”/300mm or 14”/350mm blade capacities, each model built to perform as the same exacting high specification of the standard K770, but with the addition of a detection system that guards the saw by reducing its RPM if it detects that something is wrong in order to prevent potential catastrophic engine failure. This detection system can also be quickly and easily manually de-activated if required too.
K770 OG - 3.7kW/4.96Hp. Blade Capacity 300/350mm. Max Cut Depth 100/125mm. 10/10.1kg*.
The K770 OilGuard is designed for use primarily with Husqvarna OilGuard 2-stroke oil.
The K770 OG can be purchased as a machine only or as a package (c/w Husqvarna Tacti-Cut S50 diamond blade (S50+ 14” model)) at a reduced concessionary price.

*Excluding fuel and cutting equipment
The incorporated optical detection of the K770 OilGuard is designed to prevent engine damage caused by wrong fuel-oil mix or oil type.
It is designed to be used primarily with genuine Husqvarna OilGuard high-quality 2-stroke oil which contains a colorant which the detection of the K770 OG looks for. If it is not present then the RPM of the saw is greatly reduced to prevent potential oil. Should the user wish to use other two-stroke oils (i.e non-OilGaurd oil), the preventive detection system can simply be manually de-activated can quickly and easily de-activated simply by pulling out the OilGuard button on the rear handle of the saw. Not all oils are of the same quality nor viscosity. Husqvarna OilGuard oil complies with the highest JASO/ISO-Global EBD standards and is suitable for use with all two-stroke engines.
Light and powerful
The K770 OilGuard is a light, compact and powerful machine with superior power-to-weight ratio.
High power with less fuel
Built-in automatic filter compensation SmartCarb™ maintains high power and lowers fuel consumption.
Optimised engine performance
Through efficient cylinder design, digital ignition system and Husqvarna X-Torq® engine technology which reduces emissions by up to 60% and increases fuel efficiency by up to 20%.
Digital ignition with optimised timing
Provides a powerful spark with optimised timing, enabling easy start and efficient combustion.
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.
Exceptionally low vibrations
Vibrations below 2.5m/s² in the cutter handles for improved operator comfort and longer periods of safe use.
Heavy-duty cutting arm
The cast magnesium crankcase of the K770 OilGuard has a three-bolt joint to attach the cutting head, enabling higher torsional rigidity than the previous two-bolt design solution.
Easy to change blade guard position
The light magnesium blade guard of the K770 OilGuard is quick and easy to adjust thanks to its stepless manual adjustment which requires no tooling.
Cuts close to walls or ground
Possible thanks the reversible cutting arm of the K770 OilGuard.
Easy and optimal belt tensioning
The incorporated SmartTension™ semi-automatic belt tensioning system ensures optimal power transmission, minimum wear and maximum belt life, eliminating the risk of under and over tensioning the poly V-belt.
Provides better transmission of power and requires less frequent re-tensioning and extended service intervals.
Virtually maintenance-free starter
The incorporated Durastarter™ is a dust-sealed starter where the return spring and the pulley bearing are sealed to provide a virtually maintenance-free starter, complimented by the specially developed durable starter cord.
Active Air Filtration™
Two-step filtration system with centrifugal cleaning and a single paper filter increase product life and extends service intervals.
Virtually maintenance-free air filter
The only time the filter needs to be checked and changed is if a lack of power is experienced.
Long service intervals
The use of a strong poly V-belt combined with Durastarter™ and the highly efficient Active Air Filtration™ filter system ensures long service intervals.
Less slurry and low water consumption
Excellent dust control thanks to the integral wet cutting kit supplied as standard, complete with a progressive water valve for exact adjustment of the water volume required to efficiently bind the dust and therefore reduce the volume of slurry generated.
Smooth blade stop
Reduces the stop time of the blade when the machine is switched off, enabling the user to quickly move on the next job.
