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specicationsof:APITC,ISO-L-EGC,JASOFC(LowSmoke)oil.
Recommended mixing ratio is 25:1.
FUEL WITH NO OIL (RAW PETROL) will cause severe damage to the engine which is not covered by
manufacturer’s warranty.

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.
