capacity. Fasten the fuel cap securely and wipe up any fuel
spillage around the unit.

HOW TO MIX FUEL
Petrol is flammable. Avoid smoking or bringing
any flame or sparks near fuel. Make sure to stop the engine and
allow it cool before refilling the unit. Select outdoor bare ground
for filling with fuel and move at least 3 m (10 ft) away from the
fuel filling point before starting the engine.
Your strimmer runs off a mix of semi-synthetic 2-stroke oil and
unleaded petrol (40:1). Our petrol tools come with a measuring
jug with guide lines.
Find the side marked 40:1, add your petrol to the first line and
your 2-stroke oil to the second. Replace the jugs lid and shake
the mixture for around a minute.
