• 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 presently unknown 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 operating
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.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician
about these symptoms.
• Keep the tool well maintained, fasteners tightened and worn
parts replaced.
• Mix and store fuel in a container approved for fuel.
• Mix fuel outdoors where there are no sparks or flames.
• Wipe up any fuel spillage. Move 9m away from refueling site
before starting engine.
• Stop the engine and allow to cool before refueling or storing
the unit.
• Allow the engine to cool; empty the fuel tank and secure the
unit from moving before transporting in a vehicle.
Specific Safety Rules For
Trimmer Use

water. If irritation is still present, see a doctor Immediately.
• Clean up spilled petrol immediately.
MIXING THE FUEL (Fig. 3)
• This product is powered by a 2-stroke engine and requires
pre-mixing petrol and 2-stroke oil. Pre-mix unleaded petrol and
2-stroke engine oil in a clean container approved for petrol.
• This engine is certified lo operate on unleaded petrol intended
for automotive use with an octane rating of 90 {[R + M] / 2) or
higher.
• Do not use any type of pre-mixed petrol fall from fuel service
stations, this includes the pre-mixed petrol I oil intended for use
in mopeds, motorcycles, etc.
• Use synthetic 2-stroke oil only. Do not use automotive oil or
2-stroke outboard oil.
• Mix 2% synthetic 2-stroke oil into the petrol. This is a 50:1 ratio.
• Mix the fuel thoroughly and also each time before fueling.
• Mix in small quantities. Do not mix quantities larger than usable
in a 30 day period. Synthetic 2-stroke oil containing a fuel
stabilizer is recommended.
FILLING THE TANK
• Clean surface around fuel cap to prevent contamination.
• Loosen 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 end hand lighten.
• Wipe up any fuel spillage. Move 9m 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 fuelling. Never add fuel to a
machine with a running or hot engine. Move at least gm
from refuelling site before starling engine. Do not smoke!
STARTING AND STOPPING
WARNING
Never start or run the engine inside a closed or poorly
ventilated area; breathing exhaust fumes can kill.
To start a cold engine:
• Lay the trimmer on a level surface.
• Check the ON/OFF switch to be on “ON” position.
• PRIME - press the primer bulb 6 times slowly.
• SET the choke lever to the “START” position.
• Left hand SQUEEZING the throttle trigger.
• Right hand PULL the starter rope with a quick firm and
consistent upward motion until the engine fires or starts and
runs.
Note: If difficulties with starting are experienced (this may occur in
colder conditions) refer to troubleshooting section in this manual.
• Move the choke lever to “RUN” position.
• Allow engine to warm up for 5-20 seconds.
To start a warm engine:
With the ON/OFF switch on “ON” position, PULL the starter rope
with a quick firm and consistent upward motion until the engine
starts.
To stop the engine:
Slide the switch to “OFF” position for 2 seconds until the engine
stops
OPERATING THE TRIMMER
Hold the trimmer 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.
Always operate trimmer at full throttle. Cut tall grass from
the top down. This will prevent grass from wrapping around the
shaft housing and bump head which may cause damage from
overheating. If grass becomes wrapped around the bump head,
stop the engine, disconnect the spark plug wire, and remove the
grass. Prolonged cutting at partial throttle will result in oil dripping
from the silencer.
Maintenance
WARNING
Use only original manufacturer’s replacement parts,
accessories and attachments. Failure to do so can cause
possible injury, poor performance and may void your
warranty.
• You may make adjustments and repairs described here. For
other repairs, have the trimmer serviced by an authorised
service agent.
• Consequences of improper maintenance may include excess
carbon deposits resulting in loss of performance and discharge
of black oily residue dripping from the muffler.
• Make sure all guards, straps, deflectors and handles are
properly and securely attached to avoid the risk of personal
injury.
CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port
and muffler may become blocked with carbon deposits. If you
notice a power loss with your petrol powered tool, a qualified
service technician will need to remove these deposits to restore
performance.
SPARK ARRESTOR
This machine is fitted with a spark arrestor to help prevent fires. The
spark arrestor is fitted at the muffler discharging port. To ensure
proper performance of your product, tile spark arrestor must be
cleaned or replaced every 25 hours or each year. Please contact
your nearest service dealer for a new spark arrestor. To find your
nearest service dealer please visit our website.
CLEANING AIR FILTER
A dirty air filter will cause starting difficulty, loss of performance, and
shorten the life span of the engine. Check the air filter monthly. For
best performance, replace the air filter at least once a year.
• Loosen the air filter cover by turning the fixing knob counter
clockwise.
• Remove the airbox cover and the air filter
• Clean the foam filter element with warm soapy water. Rinse
and let dry.
NOTE: If the foam filter element is damaged, it should be replaced.
• Apply a light coat of engine oil to the roam filter element, then
squeeze it out.
• Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the cover.
Installing the filter incorrectly will allow dirt to enter the engine,
causing rapid engine wear.
• Reinstall the airbox cover and tighten the fixing knob to secure.
FUEL TANK
WARNING
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a sealing gasket and a check valve to
ventilate built up fuel gasses. A clogged check valve will cause
poor engine performance. If performance improves when the fuel
cap is loosened, the check valve may be faulty. Replace fuel cap if
required.
The fuel supplied to the engine is passed through a filler to remove
any contaminants from entering the engine.
Contaminants in the fuel can cause poor performance and damage
to the engine.
The fuel filter is a non-serviceable item and if needed should be
replaced by an AUTHORISED SERVICE CENTRE.
SPARK PLUG REPLACEMENT
The electrode gap should be adjusted to 0.6-0.7mm.
IDLE SPEED ADJUSTMENT
If idle speed is too high and needs adjustment, turn the idle speed
screw counterclockwise to reduce the engine speed.
If the idle speed is too low and needs adjustment, turn the idle
speed screw clockwise to increase engine speed.
NOTE: The engine should be at normal operating temperature
before making adjustments to the idle speed.
STORING THE PRODUCT
• Clean all foreign material from the product. Store idle unit
indoors in a dry, well-ventilated area that is inaccessible to
children. Keep away from corrosive agents such as garden
chemicals.
• Abide by all ISO and local regulations for the safe storage and
handling of petrol.

seconds. If the engine has attempted
to start but fails to run on, Re-start the
engine in the half choke position (half
way between start and run) and allow
