FUEL: MIXING PETROL AND OIL

IMPORTANT:

 The engine used on this Hedge Trimmer is of a two-stroke design. The internal 

moving parts of the engine, i.e., crankshaft bearings, piston pin bearings and piston to cylinder 

wall contact surfaces, require oil mixed with the petrol for lubrication. Failure to add oil to the petrol 

or failure to mix oil with the petrol at the appropriate ratio will cause major engine damage which 

will void your warranty. For your fuel premix, only use a quality oil designed for two-stroke air-

cooled engine.

FUEL MIXTURE CHART

Refer to the chart above. 

MIXING INSTRUCTIONS:

Always mix fuel and oil in a clean container approved for petrol. Mark the container to identify it as 

fuel mix for the Hedge Trimmer. Use regular unleaded petrol and fill the container with half the 

required amount of petrol. Pour the correct amount of oil into the container then add the remaining 

amount of petrol. Close the container tightly and shake it momentarily to evenly mix the oil and the 

petrol before filling the fuel tank on the Hedge Trimmer.

When refilling the Hedge Trimmer fuel tank, clean around the fuel tank cap to prevent dirt and 

debris for entering the tank during cap removal. Always shake the premix fuel container 

momentarily before filling the fuel tank.

Always use a spout or funnel when fueling to reduce fuel spillage. Only fill the tank to within  

10 ~ 20 mm from the top of the tank. Avoid filling to the top of the tank filler neck.

NOTE:

1. 

Never mix petrol and oil directly in the Hedge Trimmer fuel tank.

2. 

Do not use National Marine Manufacturer’s Association (NMMA) or BIA certified oils. This 

type of two-stroke engine oil does not have the proper additives for air-cooled, two-stroke 

engines and can cause engine damages.

3. 

Do not use automotive motor oil. This type of oil does not have the proper additives for air-

cooled, two-stroke engines and can cause engine damage.
