FUEL AND REFUELLING
HANDLING THE FUEL SAFELY
■ ■ ■ ■ ■ Always handle fuel with care. It is highly flammable.
■ ■ ■ ■ ■ Always refuel outdoors where there are no sparks and
flames. Do not inhale fuel vapour.
■ ■ ■ ■ ■ Do not let petrol or oil come in contact with your skin.
■ ■ ■ ■ ■ Keep petrol and oil away from the eyes. If petrol or oil
comes in contact with the eyes, wash them immediately
with clean water. If irritation is still present, see a doctor
immediately.
■ ■ ■ ■ ■ Clean up spilled fuel immediately.
MIXING THE FUEL
■ ■ ■ ■ ■ This product is powered by a 2-cycle engine and
requires pre-mixing petrol and 2-cycle oil. Pre-mix
unleaded petrol and 2-cycle engine oil in a clean
container approved for petrol.
■ ■ ■ ■ ■ This engine is certified to operate on unleaded petrol
intended for motor vehicle use with an octane rating of
87 ([R + M] / 2) or higher.
■ ■ ■ ■ ■ Do not use any type of pre-mixed petrol/oil from fuel
service stations. This includes the pre-mixed petrol/oil
intended for use in mopeds, motorcycles etc.
■ ■ ■ ■ ■ Use high a quality 2-cycle self-mixing oil for air-cooled
engines. Do not use motor vehicle oil or 2-cycle out-
board oil.
■ ■ ■ ■ ■ Mix 2% oil into the petrol. This is a 50:1 ratio.
■ ■ ■ ■ ■ Mix the fuel thoroughly and also each time before
refuelling.
■ ■ ■ ■ ■ Mix in small quantities. Do not mix quantities larger than
usable in a 30 day period. A 2-cycle oil containing a fuel
stabiliser is recommended.
FILLING THE TANK
1. Clean surface around fuel cap to prevent contamination.
2. Loosen fuel cap slowly to release pressure and to keep
fuel from escaping round the cap.
3. Carefully pour fuel mixture into the tank. Avoid spillage.
4. Prior to replacing the fuel cap, clean and inspect
the gasket.
5. Immediately replace fuel cap and hand tighten. Wipe up
any fuel spillage. Move 9 m (30 ft) away from refuelling
site before starting engine.
NOTE: It is normal for smoke to be emitted from a new
engine during and after first use.

WARNING
Always shut off engine before refuelling. Never add
fuel to a machine with a running or hot engine. Move
at least 9 m (30 ft) from refuelling site before starting
engine. Do not smoke!
OPERATION
OPERATING THE TRIMMER
Hold the trimmer/brushcutter with the right hand on the rear
handle and the left hand on the front handle. Keep a firm
grip with both hands while in operation. Trimmer should be
held at a comfortable position with the rear handle about
hip height. See
Figure 11.
Always operate trimmer at full throttle. Cut tall grass from
the top down. This will prevent grass from wrapping round
the shaft housing and string head, which may cause
damage from overheating. If grass becomes wrapped
round the string head, stop the engine, disconnect the
sparking plug wire, and remove the grass. Prolonged
cutting at partial throttle will result in oil dripping from
the silencer.
