Replace string head if cracked, chipped or damaged in  
any way. Be sure the string head is properly installed  
and securely fastened. Failure to do so may cause  
serious injury.  
ments.  
It has been reported that vibrations from hand-held tools  
may contribute to a condition called Raynaud’s Syn-  
drome 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 develop-  
ment 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:  
Make sure all guards, straps, deflectors and handles are  
properly and securely attached.  
Use only the manufacturer’s replacement string in the  
cutting head. Do not use any other cutting attachment.  
Never operate unit without the grass deflector in place  
and in good condition.  
Maintain a firm grip on both handles while trimming.Keep  
string head below waist level. Never cut with the string  
head located over 76 cm (30 in) or more above  
the ground.  
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.

OPERATION  
FUEL AND REFUELLING  
WARNING  
HANDLING THE FUEL SAFELY  
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  
engine. Do not smoke!  
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  
50:1  
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.  
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.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.  
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 a high quality 2-cycle self-mixing oil for air-cooled  
engines. Do not use motor vehicle oil or 2-cycle  
outboardoil.  
Always operate trimmer at full throttle. Cut tall grass from  
the top down.This will prevent grass from wrapping 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.  
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  
are 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 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  
GRASS DEFLECTOR LINE TRIMMING  
CUT-OFF BLADE  
See Figure 7.  
ADVANCING STRING USING THE EZ LINE™ TAP  
ADVANCE SYSTEM  
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.  
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  
cut-off blade.  
4. Resumetrimming.  
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,  
STOPTHE 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.  
Fig. 7  
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.

MAINTENANCE  
6. Make sure the string head and the spool retainer are  
WARNING:  
installed on the drive shaft by turning the retainer  
clockwise to tighten.  
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.  
7. Pull the strings again to rotate the spool into cutting  
position. Push the spool retainer down while pulling on  
string(s) to manually advance the string and to check for  
proper assembly of the string head.  
You may make adjustments and repairs described here.  
For other repairs, have the trimmer serviced by an  
authorisedservicedealer.  
Consequencesofimpropermaintenancemayinclude  
excess carbon deposits resulting in loss of performance  
and discharge of black oily residue dripping from  
the silencer.  
Make sure all guards, straps, deflectors and handles are  
properly and securely attached to avoid the risk of  
personalinjury.

CLEANING THE EXHAUST PORT AND  
SILENCER  
Depending on the type of fuel used, the type and amount of  
oil used and/or your operating conditions, the exhaust port  
and silencer 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.  
Fig. 13  
SPARK ARRESTER  
The spark arrester must be cleaned or replaced every  
25 hours or yearly to ensure proper performance of your  
product. Spark arresters may be in different locations  
depending on the model purchased. Please contact your  
nearest service dealer for the location of the spark arrester  
for your model.

FUEL CAP  
WARNING:  
A leaking fuel cap is a fire hazard and must be  
replaced immediately.  
FILTER  
The fuel cap contains a non-serviceable filter and a check  
valve. A clogged fuel filter will cause poor engine perfor-  
mance. If performance improves when the fuel cap is  
loosened, the check valve may be faulty or the filter  
clogged. Replace fuel cap if required.

from the original factory adjustment. If your unit exhibits  
specific performance problem(s) where theTrouble Shooting  
Section recommends a counterclockwise needle adjustment  
and no adjustments have been made since original purchase,  
the unit should be taken to a factory authorized service dealer  
for repair. In most cases, the needed adjustment is a simple  
task for the factory trained service representative.
