■ It has been reported that vibrations from hand-held tools
■■
may contribute to a condition called Raynaud’s Syndrome in certain individuals. Symptoms may include
tingling, numbness and blanching of the fingers, usually
apparent upon exposure to cold. Hereditary factors,
exposure to cold and dampness, diet, smoking and work
practices are all thought to contribute to the development of these symptoms. It is not known at present
what, if any, vibrations or extent of exposure may
contribute to the condition. There are measures that can
be taken by the operator to possibly reduce the effects
of vibration:
a) Keep your body warm in cold weather. When operat-
ing the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major
factor contributing to Raynaud’s Syndrome.
b) After each period of operation, exercise to increase
blood circulation.
c) Take frequent work breaks. Limit the amount of
exposure per day.
d) Keep the tool well maintained, fasteners tightened
and worn parts replaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor about
these symptoms.

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
outboard oil.
■■
■ Mix 2% oil into the petrol. This is a 50:1 ratio.
■■
■■
■ Mix the fuel thoroughly and also each time before
■■
fuelling.
■■
■ Mix in small quantities. Do not mix quantities larger than
■■
are usable in a 30 day period. A 2-cycle oil containing a
fuel stabiliser is recommended.

OPERATING THE TRIMMER
See Figure 5.
Hold the trimmer with the right hand on the rear handle and
the left hand on the front handle. K eep a firm grip with both
hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Always operate trimmer at full throttle. Cut tall grass from
the top down. This will pre vent grass from wr apping round
the drive 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.
}
50:1
FILLING THE TANK
1. Clean surface round fuel cap to prevent contamination.
2. Loosen fuel cap slowly to release pressure and to keep
fuel from escaping around 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.

OPERATION
ADVANCING THE STRING
ADVANCING STRING USING THE EZ LINE™ TAP
ADVANCE SYSTEM
String advance is controlled by tapping string head on grass
while running engine at full throttle.
1. Run engine at full throttle.
2. Tap string head on ground to advance string. String
advances each time the head is tapped.
3. Several taps may be required until string strikes the cutoff blade.
4. Resume trimming.
NOTE: If the string is worn too short you may not be able to
advance the string by tapping it on the ground. If so, STOP
THE ENGINE, and manually advance the string.
ADVANCING THE STRING MANUALLY
Push the spool retainer down while pulling on string(s) to
manually advance the string.
CUTTING TIPS
See Figure 6.
■ Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
■ Do not cut in dangerous cutting area.
■ Use the tip of string to do the cutting; do not force string
head into uncut grass.
■ Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, kerbs and wood may
wear string rapidly.
■ Avoid trees and shrubs. Tree bark, wood mouldings,
cladding and fence posts can easily be damaged by
the string.
GRASS DEFLECTOR LINE TRIMMING CUTOFF BLADE
See Figure 7.
This trimmer is equipped with a line trimming cut-off blade
on the grass deflector . For best cutting, advance string until
it is trimmed to length by the cut-off blade. Advance string
whenever you hear the engine running faster than normal.
This will maintain best performance and keep string long
enough to advance properly .
