Husqvarna recommends you to use a 50:1 fuel mix ratio (gas to oil ratio) for all devices that use a 2-stroke engine with less than 75cc displacement. If the engine has more than 75cc, you may use either a 50:1 or 33:1 ratio.
The Husqvarna power cutters below 75cc – K770 and K760.
The power cutters above 75cc engine – K970, K1270
| Power Cutter | Fuel Mix Ratio |
| K760 and K770 | 50:1 |
| K970 and K1270 | 33:1 or 50:1 |
What Fuel and Oil Should be Used in a Husqvarna Power Cutters
Husqvarna 2-stroke engine tools requires mixing gasoline and oil manually or the use of a premixed fuel. Using the correct type of gasoline and oil is essential.
Premixed Fuel
For a 50:1 ratio, you may use a premixed fuel. Any type of premixed fuel won’t do! We recommend you use the Husqvarna alkylate premixed fuel for your Power Cutter as it uses fewer harmful chemicals than regular fuel.
Premixed fuel will allow the engine to remain clean for longer as deposits after combustion will be low.
Gasoline
All Husqvarna equipment requires high-quality unleaded gasoline- gasoline without lead additives- to operate.
Your gasoline must not have an octane rating of less than 87. If your gasoline’s octane rating falls below 87, the engine’s temperature will increase, eventually causing an engine breakdown.
Obtaining gasoline with higher octane levels is advised only if you are working your Cutter at high revs.
Two-stroke Oil
The Husqvarna Two-stroke oil has primarily been created for two-stroke engined Husqvarna products- and is recommended for power cutters below 75cc.
If the engine has more than 75cc, you may use oils in class JASO FB formulated for air-cooled, two-stroke engines.
Make sure that you do not use two-stroke oil for water-cooled outboard engines. Also, avoid using oil meant for four-stroke engines.
What Is the Fuel Mix Ratio for K770 and K760 Husqvarna Power Cutters?
The gasoline to oil ratio of K770 and K760 Husqvarna power cutters is 2% (1:50) when using a Husqvarna two-stroke oil or substitute.

How To Mix the Oil and Fuel in a Husqvarna Power Cutter?
Mixing the gasoline with oil must be done with utmost caution because even minor inaccuracies can create an imperfect mixture ratio which will drastically affect the performance of the Cutter.
We have created a step-by-step guide for you to learn the safest way to create a fuel mix ratio and deposit it into the fuel tank.
Creating the Fuel Mix
- Measure the gasoline amount needed for the mixture.
- Pour half of the gasoline amount into a clean container.
- Measure out and add the entire quantity of oil into the same container.
- Securely shut the container and give the mixture a good shake.
- Pour in the other half of the gasoline quantity.
- Shut the container and give it another thorough shake.
- Ensure you do not use this fuel mix for more than a month.
Filling the Fuel Tank
- Shut the engine off and allow it to cool down fully.
- Wipe down the area surrounding the fuel tank cap.
- Give the fuel container another firm shake.
- Carefully remove the fuel tank cap to allow pressure to release.
- Pour in a small amount of the fuel mixture. Be careful not to overfill it because fuel expands when it is hot and requires adequate space.
- Secure the fuel lid back onto the Power Cutter.
- Diligently wipe away fuel spillages on or around the Husqvarna Power Cutter.
- Move 3m or 10 ft away from the refueling station before starting the engine.
How to Store Fuel in the Short and Long Term?
Fuel leakages or fumes can lead to serious, life-threatening accidents if they come in contact with sparks or open flames, for example, from electrical devices.
This is why immense care must be taken when handling fuel, and approved fuel containers must be used to store and transport the fuel mixture in the short term.
Furthermore, if you do not intend to use the power tools for 30 days, remember to empty the fuel tank at a nearby gas station.
Precautionary Measures To Follow When Handling Fuel Mixtures
Fire accidents can occur because of minor mistakes! By reading the following list carefully, you will know all the dos and don’ts of fuel handling.
- Do not start the Cutter if you spot a fuel stain on the device or yourself.
- Do not create fuel mixtures indoors or near a heat source.
- Examine your Husqvarna device for fuel leaks regularly; if you identify one, do not start the Power Cutter.
- Never breathe in fuel flames and ensure there is adequate airflow.
- Do not place the Husqvarna machine or fuel conta
