Preparing to Operate the Grass Trimmer

Step 1 - Filling with Engine Fuel

This product is powered by a 2-Stroke engine and requires pre-mixing of petrol and 2-cycle oil. 

Mix a high quality 2-Stroke engine oil according JASO FC classic. Do not use automotive oil or 

2-cycle outboard oil. DO NOT mix quantities larger than usable in a 30 day period. 

1a. FUEL MIXTURE: 1 Litre (1000 ml) petrol: 25cc (25 ml) 2 Stroke engine oil (40:1 ratio)

Using the markings under the label 40:1 on the bottle pour the fuel in the left hand side (‘A’) up to 

the required level eg 5 or 10 then fill the right hand side (‘B’) up to the same corresponding mark 

with oil. Shake vigorously to mix the two products prior to pouring into the tank of brush cutter.

WARNING! 

Ensure you use the 40:1 scale as the bottle is capable of mixing 25:1 and 50:1 ratios 

also using the other scales on the reverse side.

1b. FILLING TANK

Clean surface around fuel cap to prevent contamination. Loosen fuel cap slowly. Rest the cap on 

a clean surface. Carefully pour fuel into the tank. Avoid spillage. Prior to replacing the fuel cap, 

clean and inspect the seal located inside the fuel cap. Immediately replace fuel cap and hand 

tighten. Wipe up any fuel spillage.

 Always shut off engine before fueling. Never add fuel to a machine with a running or 

hot engine. Move at least 30ft.(9 m)  from refueling site before starting engine. Do not smoke!
