Global Garden Products Brush Cutter BJ 250 BJ 250D Instructions Manual

							31
In order to ensure correct and safe
use of the brush cutter, the assembly instruc-
tions for protection and safety components
must be followed meticulously. The manufac-
turer shall not be held liable if the brush cutter
is used without the aforementioned protection
and safety devices.
CUTTING TOOLS
The use of cutting tools other than the 2-line
heads or metal disks may cause premature
wear or damage to the brush cutter.
METAL DISKS (Fig. 4)
a)Put on a pair of protective gloves before
touching the metal disk.
b) Fit into the head shaft the metal ring nut (A), the
metal disk (B), the ring nut (C), the fixed cover
(D), and the hexagon fixing nut with washer(E).
Turn anti-clockwise.
c)For safe blocking, the spindle must be
prevented from rotating: insert the steel rod (H)
(provided) into the hole on the side of the ring
nut A, turn the tool slowly until the steel rod
enters the hole on the side of the head, to block
tool rotation. Tighten the nut and remove the
steel rod from the hole.
If the warning symbol on page 4 is
applied to the brush cutter, the use of a circular
saw blade is forbidden. The use of a circular saw
blade on brush cutters with this symbol exposes
the operator to the risk of serious injury or even
death.
LINE HEAD (Fig. 5)
a) Fit into the head shaft the grooved ring nut (A)
and the metal ring nut (B). Then turn the line
head (C)anti-clockwise (the thread is left-
hand).
b)For safe blocking, the spindle must be
prevented from rotating: fit the steel rod (H)
(provided) into the hole on the side of the ring
nut A, turn the tool slowly until the steel rod
enters the hold on the side of the head, to block
tool rotation.
HARNESS (Fig. 6)
The brush cutter is provided with a single strap har-
ness. Pass the strap over your left shoulder
towards your right side. Then attach the snap hookto the supporting coupling provided on the drive
tube of the brush cutter.
In order to work more efficiently and safely, adjust
the straps according to your height and build.
PREPARATION FOR USE
In order to use the brush cutter, clothes must be
worn that protect against objects thrown up by the
tool (e.g. stones). Wear safety shoes with a slip-
proof sole, gloves, safety goggles (the visor used
on its own does not protect the eyes sufficiently),
tight-fitting clothes. Do not wear loose-fitting clo-
thes, scarves, ties, jewellery or other dangling
objects that could get caught on branches. Long
hair must be tied up and protected. Equipment to
protect hearing such as ear defenders must be
worn .
Asafety helmet must be worn while pruning, chop-
ping down trees, brush cutting or any other work in
places where falling objects are a danger.
Read the Safety instructions chap-
ter of this manual carefully.
INSPECTING THE BRUSH CUTTER
Check that all screws are fastened tightly and that
the mechanical parts are sufficiently lubricated.
Check the blade, ensure it is sharp and that it is not
damaged in any way. Check that the blade disk
guard is in place. Check that the air filter is clean.
Dirty air filters may jeopardise performance.
FUEL AND LUBRICANT 
REFILLING THE FUEL TANK
This saw has a two-stroke engine. Therefore, fuel
composed of petrol and lubricating oil for 2-stroke
engines must be used.
Only use high quality fuels and lubri-
cants to maintain engine performance and maxi-
mize the life of mechanical parts.
NEVER USE petrol alone in the
brush cutter. This would cause permanent damage
to the engine and invalidate the product Warranty.
NEVER USE fuels that have been mixed for more
than 60 days.

RECOMMENDED FUELS
Some conventional petrols are mixed with oxyge-
nating agents such as alcohol, ether compounds,
or other products suitable to reduce air pollution.
Your engine has been designed to run with any
petrol for motor propulsion, including oxygenated
petrols.
Use unleaded fuel.
Engine oil.
Only use top quality synthetic oil for 2-stroke engi-
nes.
Your dealer stocks high quality oils specifically
designed to guarantee a high level of protection to
mechanical parts and maximize engine efficiency.
Contact your local dealer.
Fuel composition 
USE A FUEL COMPOSED OF PETROL AND
SPECIFIC HIGH QUALITY SYNTHETIC OIL FOR
2-STROKE ENGINES IN A PERCENTAGE OF 2%
PETROL-TO-OIL RATIO 50:1 = 2% oil.
Warning: if synthetic oil for 2-stroke engines is not
available to prepare the fuel and you use a mine-
ral oil  specific for lubricating 2-stroke engines a
fuel with 4% oil must be prepared.
PETROL-TO-OIL RATIO 25:1 = 4% oil.
Flammable liquid!
Store fuel in appropriate containers in safe places
far from sources of heat or naked flames. Keep the
container out of children’s reach.
MIXING THE FUEL
Add oil to a container suitable to contain petrol and
oil, then add the petrol. Shake the container to mix
well.
take care over pressure that forms
inside the container.
Storing the fuel
Fuel is subject to ageing. This means that it gra-
dually loses its specifications. Do not prepare large
amounts of fuel, but supplies to last about onemonth. Always use excellent quality fuel with high
performance levels.
Before filling, shake the can well to help to mix the
oil and petrol. 
take care over pressure that forms
inside the container.
REFILLING THE FUEL TANK
Pressure may increase in recipi-
ents containing petrol due to ambient tempera-
ture.
Open the cap carefully to avoid it flying off.
Store the fuel in a cool place; never leave it in
the sun.
PRECAUTION
–(Fig. 7)Place the brush cutter in a stable
position with the tank aperture facing upwards.
–Clean the tank cap and the surrounding area to
prevent foreign bodies entering the tank.
–Fill the tank, using a suitable container that
prevents accidental fuel spillage.
–Petrol is highly flammable and in certain
conditions explosive.
–Refill the tank in a well ventilated area with the
engine switched off. Do not smoke, do not light
flames or make sparks in the filling area and in
the fuel storage area.
–Do not overfill the tank. After filling make sure
the tank cap is properly and securely closed.
–Take care not to spill any fuel while filling the
tank. Spilt fuel and its vapours may catch fire. If
any fuel has been spilt, make sure the area is
dry before starting up the engine.
–Avoid prolonged skin contact with the fuel and
breathing its vapours.
–Keep fuel out of children’s reach.
START UP
Before starting up the engine, ensure that the
range of action of the brush cutter is free of people
or objects that could be exposed to danger.
To prevent the throttle starting acci-
dentally, the throttle lever is provided with a safety
switch: the throttle lever will not work unless the
safety lever on the opposite side of the handgrip is
pressed. Before starting the brush cutter,
always ensure that that safety lever works.

Start the engine with the brush cutter in a flat
and stable position.
STARTING UP ( WITH ENGINE COLD )
–(fig. 8) set to“START” the stop switch located
on the handgrip housing the throttle lever. 
–(fig. 9)While pulling the safety lever (ref.1)and
the throttle lever (ref. 2), press the THROTTLE
LOCKOUT BUTTON (ref. 3). While keeping
the throttle lockout button  pressed, release the
throttle lever until it is locked. This operation
enables to pre-accelerate the carburettor.      
Warning: do not touch the throttle lever. In
fact, if the throttle is touched the choke
lever shuts, disengaging the starting
system.
–(fig.10)press the plastic primer ( ref . 5 )
located on the lower part of the carburettor 6-7
times. This operation brings fresh fuel to the
carburettor to aid starting.
–(fig.10)Your brush cutter has two position
indicators for the choke lever :CLOSE “--” and
RUN “I“ . Move the choke lever to CLOSE “-”
–(fig.11)Clamp the engine firmly with your left
hand. With your right hand grip the starter
handle.
–Pull the starter handle vigorously the engine
starts.
–(fig.10)Move the choke lever to RUN “I”. Pull
the starter handle again until the engine fires.
When the engine is started, the
cutting tool starts to rotate immediately. Take
the brush cutter to minimum speed by pressing
and releasing the throttle lever.
The accelerator lockout button is released and
the engine runs at minimum speed
–Allow the engine to run at minimum speed for a
few moments in order to allow the engine to
warm up.
Warning: always pull the handle firmly when
starting up the brush cutter.
PRECAUTION
–Never pull the starter handle to the full extent of
the cord (end of travel).
–Always pull the cord out straight towards the
outside. Pulling the starting cord at a different
angle causes it to rub against the bushing. This
friction causes the cord to fray and wear out
more rapidly.
–Always grip the starter handle during release.
Never allow the handle from the extendedposition to knock against the starter seat. This
could cause the cord to become caught up or
wear or damage to the starter assembly.
–Never hold the brush cutter still by placing your
foot or knee on the drive tube; this could deform
the transmission shaft making it unusable.
When the engine is started, the
cutting tool starts to rotate immediately. Take
the brush cutter to minimum speed by pressing and
releasing the throttle lever.
Check that the cutting tool stops turning when
the engine is running at minimum speed.
NOTE:If the engine does not start up after having
repeated the operations, see the paragraph on
Troubleshooting.
STARTING UP ( WITH ENGINE WARM )
The start-up procedure with the engine warm is
identical to the one with the engine cold, except for
the fact that it is not necessary to use the choke
lever positioned on the carburettor.
STOPPING THE ENGINE (Fig. 12)
Release the throttle trigger. Allow the engine to
return to minimum speed. Position the switch to
STOPuntil the engine stops.
ADJUSTING THE CARBURETTOR
Carburation of all brush cutters produced is perfor-
med by the manufacturer.
Check that the air filter is clean and fitted correctly.
The “shutter” adjustment screw (mechanical
screw) is set so that the cutting tool does not rota-
te when the engine is at minimum speed.
If the cutting tool rotates with the engine at mini-
mum speed, turn the adjustment screw of the shut-
ter (positioned at the side of the choke lever on the
carburettor)(Fig.13, ref. T)counter-clockwise until
the tool stops.
In this situation the engine must in any case conti-
nue to run and rotation must be regular.
If the brush cutter requires other adjustments,
we recommend you contact your Dealer or an
Authorised Service Centre.

CUTTING INSTRUCTIONS
FURTHER SAFETY PRECAUTIONS
Before using the brush cutter re-read all the safety
instructions in this manual. 
WARNING / PRECAUTIONS
–IF YOU ARE NOT FAMILIAR with use of the
brush cutter, practise the procedures with the
engine switched off and the switch in the OFF
“STOP” position.
–ALWAYS FREE THE WORK AREA of objects
such as cans, bottles, stones, etc.. Hitting these
objects can cause serious injury to the operator
or others present and damage the brush cutter.
If you accidentally knock against an object,
SWITCH OFF THE ENGINE IMMEDIATELY
and inspect the cutter. Never work with a
damaged or faulty brush cutter.
–ALWAYS CUT OR MOW AT FULL SPEED.
Never work at low speed, either at the start of
or during operations.
–DO NOT USE the brush cutter for purposes
other than to cut grass. DO NOT CUT above
knee level.
–DO NOT USE the brush cutter with other
people or animals nearby. Keep a minimum
distance of 15 metres between the operator
and other people or animals when cutting or
moving around. During more difficult mowing
operations keep a minimum distance of 30
metres between the operator and other people
or animals.
–IF THE BRUSH CUTTER IS USED ON
SLOPES remain below the cutting unit. DO
NOT USE THE BRUSH CUTTER if there is
even the minimum risk of slipping or
overbalancing.
–DO NOT USE the brush cutter
CONTINUOUSLY, for lengthy times. PAUSE
NOW AND AGAIN, switching off the engine.
BRUSH CUTTER USE
Read the Safety instructionschap-
ter of this manual carefully.
METAL DISKS
The 4-pointed disk is suitable for cutting tough
grass over wide areas. To cut grass, use the brush
cutter as you would a manual scythe: cut the grass
by moving the brush cutter from right to left, then
bring it back to the right, keeping it out of the vege-
tation, and so on. Cut the grass with circular swee-ping movements of about 60° - 90°(Fig. 14).
The 3-pointed disk is suitable for cutting scrub and
small shrubs up to a diameter of 2 cm.
In this case, start cutting the vegetation from above
and bring the cutting head downwards in order to
cut the branches into little pieces (Fig. 15).
When you are using the metal disk
make sure that your brush cutter is fitted with
the relevant front guard , without line-cutting
blade, which is supplied with the brush cutter
and can be found in the packaging.
When using metal tools there is a
risk of recoil when the equipment comes into
contact with solid objects (trunks, branches,
stones, etc.). If the equipment does bounce
back, it will be difficult to control and may seri-
ously jeopardize the safety of the operator and
badly damage the brush cutter. Never bring the
rotating blade into contact with the ground.
LINE HEAD
WARNING: DO NOT USE lines other than nylon
(i.e. metal wire, plasticated metal wire) and/or
that are unsuitable for the head in use. This
could cause serious injuries and lesions.
When the line head is used, the
guard must be fitted with line-cutting blade .
Do not use very worn heads: some
components could become detached and
endanger the operator.
The brush cutter you have purchased is equipped
with a “Tap & Go” head.
To release new line: with the engine at full speed,
tap the line head against the ground (Fig. 16). Line
is automatically released. The blade cuts excess
line.
PRECAUTIONS: Periodically remove any grass
wound around the brush cutter to prevent over-
heating of the drive shaft. Grass caught around
the shaft can become wound under the guard
of the grass cutting head, reducing the tool
rotation speed (Fig.17). Remove any grass
caught up using a screwdriver or other similar
tool to allow the shaft to cool correctly and the
tool to rotate freely.
–CUTTING TECHNIQUES
When the brush cutter is correctly equipped
with the guard and line head, it can eliminate
tall grass and unsightly weeds in front of
fences, walls, foundations, pavements, around
trees, etc.. This brush cutter may also be used

to eliminate unwanted vegetation from fields,
for easy preparation of the garden or to clear a
particular area of the garden completely.
NOTE:Even with the guard fitted, cutting
around pavements, foundations, walls, etc. can
cause above average wear on the line.
CUT / MOVEMENT
Walk at a regular pace, with a side to side
movement, similar to traditional scything. Do
not tilt the line head during operation. Try
cutting a small area at the correct height. Keep
the line head at a constant distance from the
ground to obtain an even cutting height (Fig.
18).
PRECISION CUT
Position the brush cutter straight, slightly tilted
until the lower part of the head touches the
ground and the cutting line is in the required
point. Always cut away from the operator. Do
not move the brush cutter by bringing the head
with nylon line towards the operator.
CUTTING BESIDE FENCES / FOUNDATIONS
(Fig. 19)
Bring the line head towards fences, posts,
rocks, walls, etc. slowly, without hitting them
hard.
If the line comes into contact with rocks, walls,
foundations etc. it may break or wear. If the line
gets caught up in fencing it may become
severed, breaking suddenly.
CUTTING AROUND TREES (Fig. 20)
Cut by gradually approaching tree trunks to
prevent the line from knocking against the tree.
Walk around the tree from left to right. Move the
end of the line towards the grass to cut, keeping
the line head tilted slightly forwards.
NOTE:The nylon line may CUT OR DAMAGE
SMALL BUSHES. The impact of the nylon line
against the trunk of bushes or trees with soft
bark MAY CAUSE SERIOUS DAMAGE TO
THE PLANT.
WARNING:Take great care when mowing.
Keep a distance of 30 metres between the
operator and other people or animals.
MOWING
In more severe mowing conditions tilt the head
with nylon line about 30 degrees to the left.
Adjust the handgrip if you wish to obtain better
control during this operation. Do not operate in
this way if there is even a slight chance ofthrowing up foreign bodies that could harm
people, animals or other objects (Fig.21).
WARNING: DO NOT SWEEP WITH THE
BRUSH CUTTER tilting the line head. Do not
use the brush cutter to remove dirt from
pavements, etc.. Your tool is powerful and
can hurl small stones etc. for a distance of
15 metres or more, wounding or injuring
people and animals or damaging to nearby
objects such as cars, windows etc. (Fig. 22).
NORMAL MAINTENANCE
–REPLACING THE GRASS-CUTTING HEAD
LINE
To replace the nylon line, follow the instructions
enclosed with the head (supplementary page
separate from the guide)
Never replace the nylon line
with a line made of any other material (e.g.
metal wire). 
–SHARPENING 3- OR 4-POINTED DISKS
WEAR PROTECTIVE GLOVES
TO PERFORM THE OPERATIONS
DESCRIBED BELOW
Sharpen with a suitable flat file(Fig. 23).
Figure 24 and 25show:
A) The wrong way to sharpen
B) Sharpening limits
C) Wrong or unequal angles
All teeth must be sharpened in the same way.
Both sides of the 3- and 4-pointed disks can be
used. When one side is worn, the disk can be
turned over in order to use the other side.
Put on a pair of gloves before sharpening to
avoid cutting yourself. It is important to ensure
the brush cutter is correctly balanced even after
sharpening.
The metal disk must never be repaired: the disk
must be replaced as soon as you notice any
breakage or if the sharpening limit has been
exceeded.
Remove the spark plug cap befo-
re sharpening.
