• The string head will rotate during carburettor
adjustments and engine starting.
• It has been reported, in certain individuals, that
vibrations from hand-held tools may contribute to a
condition called Raynaud’s Syndrome. Symptoms may
include tingling, numbness and blanching of the ngers,
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.
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.

7
• Mix and store fuel in a container approved for petrol
clearly identied as 2-stroke.
• Mix fuel outdoors where there are no sparks or ames.
Wipe up any fuel spillage. Move 10m (30ft.) away from
the refuelling site before starting the engine.
• Stop the engine and allow to cool before refuelling or
storing the unit.
• Allow the engine to cool; empty the fuel tank and
secure the unit from moving before transporting in a
vehicle.
• Replace the 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 can cause serious injury.
• Make sure all guards, straps, 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.
To install any other brand of cutting head to this string
trimmer may result in serious personal injury.
• Never operate the unit without the grass guard in place
and in good condition.
• Maintain a rm grip on both handles while trimming.
Keep the string head below waist level. Never cut with
the string head located over 76cm (30in.) above the

Preparation
Filling with engine fuel
Danger of injury! Fuel is explosive!
Turn off and cool the motor down before filling the tank with fuel. You must observe
all safety instructions relating to handling fuel.
Risk of device damage!
The device is supplied without motor or gearbox oil.
ATTENTION! Before operating, you must fill it with fuel.
WARNING! Always switch the engine off before fuelling. Never add fuel to
a machine with a running or hot engine. Move at least 30ft. (9m) from the
refuelling site before starting the engine. Do not smoke!
IMPORTANT! Keep the bottle at while lling and use a funnel.
This product is powered by a 2-stroke engine and requires pre-mixing of petrol and
2-stroke oil. Mix a high quality 2-stroke engine oil, according to JASO FC classic. Do not
use automotive oil or 2-stroke outboard oil. DO NOT mix quantities larger than usable in a
30-day period.

14
1a. Fuel mixture:
1 Litre (1000ml) petrol: 25cc (25ml) 2-stroke engine oil (40:1 ratio).
Using a funnel and keeping the bottle level, pour the fuel to the line marked PETROL; and
pour engine oil to the line marked OIL. Shake vigorously to mix the two products prior to
pouring into the tank of the grass trimmer.
1b. Filling tank
Clean the surface around the fuel cap to prevent contamination. Loosen the fuel cap slowly.
Rest the cap on a clean surface. Carefully pour fuel into the tank, avoiding spillage. Prior to
replacing the fuel cap, clean and inspect the seal located inside the fuel cap. Immediately
replace the fuel cap and hand tighten. Wipe up any fuel spillage.
NOTE: It is normal for smoke to be emitted from a new engine after rst use.
Emptying engine fuel
Only ever empty the tank outdoors or in well-ventilated rooms. Make sure not to spill fuel or
chain oil into the soil (environmental protection). Use a proper base.
Hold a collection container beneath the fuel drain bolt.
Unscrew the tank cap and remove it.
Allow the fuel to run out completely.
Screw the tank cap rmly by hand.
Operation
When working with the equipment, the appropriate plastic guard hood for ‘cutting blade
mode’ or ‘cutting line mode’ must be tted to prevent objects being thrown out by the
equipment.
The integrated blade in the cutting line guard hood automatically cuts the line to the
optimum length.

15
Start the engine
Do not start the unit until it has been completely assembled.
Danger of injury!
Do not operate the device unless you did not find any faults. If a part has become
defective, be sure to replace it before you use the device again.
Check before use!
Check the safe condition of the device.
Check the device for leaks.
Check the device for visual defects.
Check that all parts of the device have been securely tted.
Check that all safety devices are in proper condition.
Danger of injury!
Before starting work, always check the ground and remove all objects which could be
thrown by the device.
Once the machine has been set up properly, start the engine as follows:
1. Set the equipment down on a hard, level surface.
2. Push the engine switch to the ‘1’ position.

16
3. Put the choke lever on the position.
4. Press the fuel pump more than 5 times.
5. Press and hold the machine then, pull the recoil starter handle 5-6 times until the engine starts.
6. Adjust the choke lever to position. Pull the recoil starter again to start the engine.

17
7. Run the machine for 30 seconds at idle speed, clutch lock-off lever and throttle lever at
the same time.
8. Adjusting line length while working:
9. This machine is tted with a ‘Tap & Go’ head.To release more line, tap the cutting
line head against the ground with the engine at top speed, the line will be released
automatically and the knife will cut off the excess length.
If you experience any problems, turn off the engine and the machine will stop running. To
stop the cutting head, release the throttle lever.
The further you push the throttle lever, the higher the motor speed. When releasing the
throttle lever, the motor becomes idle and the cutting tools will stop.
If the machine is hot, the choke level can be adjusted to position directly when restart
the machine.
NOTE: If the engine does not start up after several attempts, refer to the section
‘Troubleshooting’.
NOTE: Always pull the starter cord out in a straight line. If it is pulled out at an angle,
friction will occur on the eyelet. As a result of this friction, the cable will become frayed and
will wear away faster. Always hold the starter handle when the cable retracts. Never allow
the cable to snap back when it has been pulled out.
NOTE: Do not start the motor in tall grass.

18
Stop the engine
Push the engine switch to the ‘0’ position
ATTENTION: When the engine has been switched off, the cutter continues running for
several seconds; therefore, do not touch the cutting head of the brush cutter until it has
come to a complete stop!
Working instructions
Extending the cutting line
CAUTION! Do not use any kind of metal wire or metal wire encased in plastic in the line
spool. This may cause serious injury to the user. To extend the cutting line, run the engine
at full speed and tap the line spool on the ground. This will automatically extend the line.
The blade on the safety shield will cut the line to the appropriate length.
IMPORTANT: Remove all grass and weed remnants at regular intervals to prevent the shaft
tube overheating. Lawn, grass and weed remnants become trapped under the safety shield
and prevent the shaft tube from receiving adequate ventilation. Remove these remnants
using a tool not bare hands.
Different cutting methods
When the equipment is correctly assembled, it will cut weeds and long grass in places
which are difcult to access, e.g. along fences, walls and foundations, and trees. It can also
be used for ‘mowing’ vegetation to prepare a garden for other applications.

19
ATTENTION: Even if it is used carefully, cutting around foundations, stone or concrete
walls will result in the line suffering more than normal wear.
Trimming/mowing
Swing the trimmer from side to side in a scything motion. Always keep the line spool
parallel to the ground. Check the site and decide which cutting height you require. Guide
and hold the line spool at the required height to obtain an even cut.
Low trimming
Hold the trimmer right in front of you at a slight angle so that the underside of the line spool
is above the ground and the line strikes the correct target. Always cut away from yourself.
Never draw the trimmer towards yourself.
Cutting along fences/foundations
Approach wire mesh fences, lath fences, natural stone walls and foundations slowly so that
you can cut close to them without striking the obstacle with the line. If, for example, the line
strikes stones, stone walls or foundations, it will wear or fray. If the line strikes wire fencing,
it will break.
Trimming around trees
When trimming around tree trunks, approach slowly so that the line does not strike the
bark. Walk around the tree, cutting from left to right. Approach grass or weeds with the tip
of the line and tilt the line spool forwards slightly.
WARNING! Take extreme care during mowing work. When doing such work,
keep a distance of 30 metres between yourself and other people or animals.
Mowing
When mowing, you want to cut all the vegetation down to the ground. To do this, set the
line spool at an angle of 30° to the right. Place the handle in the required position. Take into
consideration the danger of objects being thrown by the machine.
WARNING! Do not use the equipment to remove objects from footpaths,
etc. The equipment is a powerful tool and can throw small stones and other
objects a distance of 15 metres or more, causing injuries and damage to
cars, houses and windows.

20
Jamming
If the cutting blade jams as a result of attempting to cut vegetation that is too dense, switch
off the engine immediately. Remove the grass from the equipment before you restart it.
Maintenance
WARNING: Always wear protective gloves when working on or around
cutting tools.
When not in use, transport or storage, always install the transport protection on all cutting
tools.
Before performing any maintenance or cleaning work, always turn off the engine and pull
out the spark plug boot.
1. Do not spray the unit with water. It damages the engine.
2. Clean the unit with a cloth or brush, etc.
