OPERATION

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 vapours.
■ Do not let petrol or lubricant come in contact with your
skin.
■ Keep petrol and lubricant away from the eyes. If petrol
or lubricant comes in contact with the eyes, wash
them immediately with clean water. If irritation is still
present, see a doctor immediately.
■ Clean up spilled petrol immediately.
Mixing the fuel
■ This product is powered by a 2-stroke engine and
requires pre-mixing petrol and 2-stroke lubricant.
Premix unleaded petrol and 2-stroke engine lubricant
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
91 ([R + M]/2) or higher.
■ Do not use any type of pre-mixed petrol/lubricant from
fuel service stations.
■ Use synthetic 2-stroke lubricant only. Do not use
automotive lubricant or 2-cycle outboard lubricant.
■ Mix 2% synthetic 2-stroke lubricant 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 synthetic 2-stroke
lubricant containing a fuel stabiliser is recommended.

Filling the tank
■ Clean surface around
contamination.
■ Loosen the fuel cap slowly to release pressure and to
keep fuel from escaping around the cap.
■ Carefully pour fuel mixture into the tank. Avoid spillage.
■ Prior to replacing the fuel cap, clean and inspect the
gasket.
■ Immediately replace fuel cap and hand tighten. Wipe
up any fuel spillage. Move 9 m 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.
Always shut off engine before fuelling. Never add fuel to
a machine with a running or hot engine. Move at least 9
m (30 ft) from refuelling site before starting the engine.
Do not smoke.

OPERATING THE TRIMMER

See fi gure 7.
■ Hold the trimmer with the right hand on the trigger
handle and the left hand on the left handle. Keep a
firm grip with both hands while in operation.
■ Trimmer should be held at a comfortable position with
the trigger handle about hip height.
■ Always operate trimmer at full throttle. Prolonged
cutting at partial throttle will result in lubricant dripping
from the silencer.
■ Cut tall grass from the top down. This will prevent grass
from wrapping around the shaft housing and string
head which may cause damage from overheating.
■ If grass becomes wrapped around the string head,
stop the engine, disconnect the spark plug wire, and
remove the grass.
