Never touch the spark plug or plug HT cable while the engine is in operation, doing so may result in an 

electrical shock.   

 

Never touch the exhaust, spark plug, or any metallic parts while the engine is in operation or 

immediately after shutting down the engine, these parts reach high temperatures during operation and 
doing so could result in serious burns. 

 

When you finish cutting in one location and wish to continue work in another area, stop the engine.   

 

Always remove fuel from the fuel tank before transportation to prevent fuel spillage. 

 

Never leave the grass trimmer exposed to direct sunlight as this can heat the fuel tank and may cause 

a discharge of fuel, and flood the engine.   

 

Be careful not to hit the nylon cutting head against stones or the ground.   

TWO-STROKE  FUEL 

 

 

 

 

 

Fuel is very flammable. Do not smoke or bring any flame or sparks near fuel. 

 

Always stop the engine and allow it to cool before refuelling. 

 

Refuel outdoors on bare ground, restart engine at least 5m away from the refuelling stop. 

 

The engine is lubricated by oil mixed into petrol. Prepare a mixture of unleaded petrol and 
semi-synthetic two-stroke oil that meets the specifications of: API TC, ISO-L-EGC, JASO FC 
(Low Smoke)  oil. 
 

 

 

Recommended mixing ratio is 40:1 

 

 

FUEL WITH NO OIL (RAW PETROL) will cause severe damage to the engine which is not 
covered by manufacturer's warranty. 

 

Use fresh, unleaded petrol (95 RON) and semi-synthetic oil specially made for high performance 
two-stroke engines. Mix in a ratio of 

40 parts petrol to 1 part of oil

.

 

 

By using two-stroke oil specially made for two-stroke engines you will reduce the formation of ash and 
carbon deposits on the spark plug, piston, exhaust muffler and cylinder as well as reducing emissions of 
harmful exhaust gases.

 

 

Oil FOR 4-CYCLE ENGINES should not be used as two-stroke lubrication oil as it can cause fouling of 
the spark plug, exhaust port blocking, piston ring sticking and other internal engine damage.

 

 

FUEL STORAGE 

 

 

Mixed two-stroke fuel which has been left unused for a period of one month or more may damage the 
carburettor and result in the engine failing to start or operate correctly. 

 

When storing the grass trimmer for a period of more than one month, empty the fuel tank, and run the 
engine to empty the carburettor of fuel. 

 

Two-stroke fuel can cause deterioration of rubber and/or plastic components during prolonged storage. 

 

It is important to only use good quality, fresh fuel mix. 

 

FUELLING

   

 

 

Shake the fuel container to thoroughly mix the two-stroke oil and petrol.

 

 

Clean dirt from around the fuel cap before removing. 

 

Pour two-stroke fuel into the fuel tank with a filtered funnel, up to 80% of the fuel tanks capacity. 

 

Replace the fuel cap and tighten securely. Spilled fuel must be wiped away from the grass trimmer 
before starting the engine. 

 

Move at least 5m away from the refuelling area before restarting the engine. 

 

 

 

 

When refilling the tank, always turn off the engine and allow it to cool down. Take a 
careful look around to make sure that there are no sparks or naked flames anywhere 
nearby before refuelling.
