GGP Italy SPA Brush Cutter TR 25J Instructions Manual

							In order to ensure correct
and safe use of the edge trimmer, the assem-
bly instructions for protection and safety
components must be followed meticulously.
The manufacturer shall not be held liable if
the edge trimmer is used without the afore-
mentioned protection and safety devices.
FRONT HANDGRIP (fig. 1)
Edge trimmers are normally supplied with the
front handgrip disassembled inside the packag-
ing. 
Therefore, it must be attached following the pro-
cedure indicated below. 
The front handgrip must be attached. A plastic
spacer (E) is positioned on the drive tube, ensur-
ing a minimum distance between the rear and
front handgrips. The front handgrip must be
positioned on the drive tube in front of this spac-
er. Fit the square nuts in the specific seats in the
handgrip, then fit the screws with washers.
Tighten the screws gradually and uniformly.
Before fully tightening, adjust the position of the
front handgrip. 
Terminate by tightening the screws to the same
degree.
Do not modify or damage
the plastic spacer. Comply with the minimum
distance between handgrips. Always work in
safety.
Never work with hand-
grips that are not correctly fastened or loose.
FRONT GUARD (fig. 2)
The guard must be fitted
so as to comply with the correct position of
the line cutting blade and to protect the oper-
ator.
Never work without the guard. 
The guard must be fitted using the specific
screws and washers provided.
The guard must be the correct type both for the
model of edge trimmer and for the cutting tool
used.

Line up the slot (A) on the joint (B) with the raised
notch (C) on the lower part of the rod (D).
Pull out the stop pin (E) and push the lower part
of the rod (D) right down until the stop pin E)
slots in the hole (F) on the rod.
This is easier to do if you rotate the bottom of the
rod (D) slightly in both directions. The pin (E) is in
place when it is completely lodged in the hole.
Lastly, tighten the knob (G) securely.
CUTTING TOOLS
The use of cutting tools
other than the 2-line heads may cause premature
wear or damage to the edge trimmer.
The use of metal disks of
any type is strictly prohibited on this edge
trimmer.!DANGER!
IMPORTANT
ASSEMBLY INSTRUCTIONS27EN
ASSEMBLY INSTRUCTIONS 
						

							In order to use the edge trimmer, 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 clothes, scarves, ties, jewellery or
other dangling objects that could get caught on
branches. Long hair must be tied up and pro-
tected. Equipment to protect hearing such as ear
defenders must be worn.
INSPECTING THE EDGE TRIMMER
Check that all screws are fastened tightly and
that the mechanical parts are sufficiently lubri-
cated. Check that the air filter is clean. Dirty air
filters may jeopardise performance.
FUEL  
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 lubricants to maintain engine performance
and maximize 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.
Some conventional petrols are mixed with oxy-
genating agents such as alcohol, ether com-
pounds, 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
engines.
Your dealer stocks high quality oils specifically
designed to guarantee a high level of protection
to mechanical parts and maximize engine effi-
ciency.
Contact your local dealer.
IMPORTANT
IMPORTANT
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.
(SYNTETIC OIL 2T)
If synthetic oil for 2-stroke
engines is not available to prepare the fuel and
you use a mineral oil  specific for lubricating 2-
stroke engines a fuel with 4% oil must be pre-
pared.
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.
Fuel is subject to ageing. This means that it
gradually loses its specifications. Do not prepare
large amounts of fuel, but supplies to last about
one month. 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.!WARNING!
!DANGER!
IMPORTANT
28PREPARATION FOR USEEN
PREPARATION FOR USE 
						

							REFILLING THE FUEL TANK
Pressure may increase in
recipients containing petrol due to ambient
temperature.
Open the cap carefully to avoid it flying off.
Store the fuel in a cool place; never leave it in
the sun.
–Place the brush cutter in a stable position with
the tank aperture facing upwards (fig. 3).
–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.
–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 fill-
ing 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.
Start the engine with the brush cutter in a flat
and stable position.
To prevent the throttle starting accidentally, 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.
STARTING UP (WITH ENGINE COLD)
– Set the start/stop switch, located on the hand-
grip housing the throttle lever to «START»(fig.
4).
!WARNING!
!DANGER!
!WARNING!
– Pressing both the safety lever (ref.1) and the
accelerator (ref.2) simultaneously, press the
ACCELERATOR STOP button (ref.3) Keep
pressing the accelerator stop button and
release the accelerator lever until it locks. This
operation allows pre-acceleration of the carbu-
rettor (fig.4) .
– Turn the choke lever (ref. 4) on the carburettor
(rotate towards the engine body). (fig. 5).
Do not touch the accelerator
lever. By accelerating in fact the accelerator stop
will  be enabled.
– 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. 5).
– Your machine has 2 position indications for the
choke:  CLOSE “--”and RUN I. Move the
choke to the CLOSE position fig. 5).
– Hold the engine firmly in place with your left
hand. With your right hand grip the starter han-
dle (fig.6).
– Firmly pull the starter handle until the engine
shows signs of starting.
– Then move the choke to the RUN “I” position.
Pull the starter handle again to start the engine.
(fig.5).
Always pull the handle firm-
ly when starting up the brush cutter.
When the engine starts, the
trimmer tool starts rotating immediately. Press
then release the accelerator lever. The accelera-
tor stop button will be released and the engine
will start ticking over at minimum power.
– The engine runs at minimum speed. Allow it to
idle for a few moments to gradually warm up
the engine.
–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 extended
position 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 unus-
able.
When the engine is start-
ed, the cutting tool starts to rotate immedi-
ately. Take the brush cutter to minimum
speed by pressing and releasing the throttle
lever. Check that the cutting tool stops turn-
ing when the engine is running at minimum
speed.
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. 7)
Release the throttle trigger. Allow the engine to
return to minimum speed. Position the switch to
STOP until the engine stops.
ADJUSTING THE CARBURETTOR
Carburation of all brush cutters produced is per-
formed by the manufacturer.
Check that the air filter is clean and fitted cor-
rectly.
The “shutter” adjustment screw (mechanical
screw) is set so that the cutting tool does not
rotate when the engine is at minimum speed.
If the cutting tool rotates with the engine at min-
imum speed, turn the adjustment screw of the
shutter (positioned at the side of the choke lever
on the carburettor) (fig. 8, ref. T) counter-clock-
wise until the tool stops.
In this situation the engine must in any case con-
tinue to run and rotation must be regular.
If the brush cutter requires other adjust-
ments, we recommend you contact your
Dealer or an Authorised Service Centre. 
NOTE
!WARNING!
30PREPARATION FOR USEEN 
						

							–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 opera-
tor and other people or animals when cut-
ting or moving around. During more diffi-
cult mowing operations keep a minimum
distance of 30 metres between the opera-
tor 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 over-
balancing.
–DO NOT USE the brush cutter CONTINU-
OUSLY, for lengthy times. PAUSE NOW
AND AGAIN, switching off the engine.
LINE HEAD
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 you use the line
head, the front guard must be fitted with a
line-cutting blade. Fit the bottom band pro-
vided with the line-cutting blade to the guard.
Do not use very worn heads: some compo-
nents 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,
!WARNING!
!WARNING!
tap the line head against the ground (fig. 9). Line
is automatically released. The blade cuts excess
line.
Periodically remove any
grass wound around the brush cutter to prevent
overheating 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. 10). 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.
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 elim-
inate unwanted vegetation from fields, for easy
preparation of the garden or to clear a particular
area of the garden completely.
Even with the guard fitted,
cutting around pavements, foundations, walls,
etc. can cause above average wear on the line.
• Cut / movement (fig. 11)
Walk at a regular pace, with a side to side move-
ment, 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
• Precision cut
Position the edge trimmer 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 edge trimmer by bringing the line head
towards the operator.
• Cutting beside fences / foundations (fig. 12)
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 sev-
ered, breaking suddenly.
NOTE
IMPORTANT
CUTTING INSTRUCTIONS31EN
CUTTING INSTRUCTIONS 
						

							• Cutting around trees (fig. 13)
Cut by gradually approaching tree trunks to pre-
vent 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.
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.
• Mowing (fig. 14)
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 of throw-
ing up foreign bodies that could harm people,
animals or other objects.
DO NOT SWEEP WITH THE
EDGE TRIMMER tilting the line head. Do not
use the edge trimmer 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. 15)
.
