Maximum shaft speed.  
Use of the manual  
• Anyone who uses the machine should have read the  
entire manual with extreme care.  
Make sure the machine is correctly assembled, and all  
its parts are working properly. Make sure the screws are  
all in place and securely tightened. Check operation of  
the accelerator control block and make sure there is no  
leakage of fuel. Check that the cutting tool does not  
move with the motor running at idle speed. Make sure  
the transmission pipe is properly fastened to the motor  
joint and the line cutter head or blade are correctly fas-  
tened with the screw fastening the blade fully tightened.  
• All users should be familiar with the operations for use  
of the machine under absolutely safe conditions as  
described in this manual, and should be instructed in  
the proper cutting techniques to use, possibly by  
practical demonstration.  
• Do not allow children or persons who are not familiar  
with these instructions and are not sufficiently trained  
to use the brush cutter. Local regulations may specify  
an age limit for users.  
Replace any accessories (blades, nylon string  
2
heads, guards) which show damage or cracks or  
• Keep this manual with the machine when selling  
or lending it, to enable the future users to familiar-  
ize themselves with the product and instructions  
for safe use.  
• All parts of the manual are equally important for the  
purpose of preventing injury to the operator or dam-  
age to the machine. To facilitate your reading, section  
B is divided into parts that can be called up in the rest  
of the manual, marked with the "CAUTION" symbol  
followed by the number of the corresponding para-  
graph, to concentrate your attention on the main  
safety procedures related to a particular situation.  
appear excessively worn. Have your Authorized Service  
Center replace any damaged parts. For nylon string  
heads, use only strings made of flexible material recom-  
mended by the manufacturer. For example, you should  
never use metal wire because it could cause serious  
injuries to people, property and animals. An unsuitable  
string could break and turn into a very dangerous mis-  
sile. In mounting the cutting utensils follow the instruc-  
tions in the chapter entitled "Usable cutting tools and  
their installation on the machine". ABSOLUTELY DO  
NOT USE THE BRUSH CUTTER IF THE SPECIFIC  
SAFETY GUARD FOR THE CUTTING DEVICE IN USE  
IS NOT SECURELY FASTENED (see chapter  
Prior to use  
"Assembly/disassembly"). Failure to follow this rule can  
expose you to serious danger such as:  
• Respect of the procedures described in this manual  
does not eliminate the risks of accidents but does  
reduce the probability of their occurring or the effect  
of the damage.  
• possible contact with rotating and cutting parts;  
• possible contact with flying debris.  
Never use a brush cutter without its safety pole  
guard correctly in place. Only use blades or nylon  
string heads clearly marked with a maximum speed  
• If you have never used a brush cutter before, prac-  
tice using it for a while before actually starting to  
work with it.  
-1  
of at least 10,500 min .  
• The operator or user is responsible for any damages  
to third parties or their property, and for any dangers  
to which they may be subject.  
• Do not use this machine for any other purpose than  
that for which it was designed, using the proper cut-  
ting devices as indicated in the instructions.  
• Do not use the machine if you are tired, in poor health  
or under the effects of alcohol or medication that  
could affect your reactions.  
Use only original or approved accessories and  
3
spare parts, which you can purchase from our  
official distributors. The use of other accessories and  
spare parts increases the danger of injury and in this  
case the manufacturer has no liability for damage to  
persons or property. Never attempt to use the machine  
if it is incomplete, defective or has been altered by any-  
one other than an Authorized Service Center. The risk of  
accidents increases considerably if maintenance is not  
carried our regularly in a professional way. In case of  
doubt contact an authorized service center.  
• Make sure you know how to stop the engine and  
blade if necessary (see section entitled "Starting and  
stopping the engine").  
Inspect the machine carefully before every use, in  
case of violent impact or signs of malfunction.  
All operations of maintenance, assembly, disas-  
sembly and fueling should be done with the

machine on a flat, solid surface so that the motor can-  
not turn over, in a stable position with the motor off,  
the switch turned to O/STOP, the cutting tool stopped  
and wearing adequate protective gloves.  
Twigs or grass may jam between the safety guard  
and the blade or nylon string head. Never try to  
10  
remove this material with the engine running and/or the  
blade rotating. Watch out for the rotating parts and hot  
surfaces of the machine. Contact between the blades  
and any extraneous objects could cause serious injury to  
the operator or other people or animals in the vicinity, and  
could also damage the machine. Cut only the material  
recommended for each accessory and take care not to  
let the blades come into contact with rocks, metal parts,  
etc. The blade is sharp, so be very careful when handling  
it even with the engine off.  
Apparel  
Dress suitably for the job; wear approved personal  
5
protection gear:  
Closely fitting protective clothing (do not wear shorts or  
loose clothing). Do not wear jewelry that could get  
caught in moving parts of the machine.  
Safety boots with non-slip sole, crush-resistant toe cap  
and protection against cuts (do not wear sandals or  
work barefoot).  
Sturdy gloves resistant to cuts and vibrations.  
Safety visor or protective goggles. Remove the protec-  
tive film if any.  
Hearing protection.  
Hard hat (if there is any risk of falling objects).  
Keep any other persons or animals away from the  
11  
work zone (minimum distance 15 meters). Since  
there is a danger when you are working that the blade or  
nylon string head could throw out grass, dirt, rocks or for-  
eign bodies, when someone approaches switch the  
engine off or stop the blade or rotating head (see section  
entitled "Starting and stopping the engine"). Fasten your  
hair above shoulder length. Start the machine in a flat  
place, in a stable position, making sure the cutting tool  
does not touch any obstacles. Use the machine holding it  
to the right of your body so that the exhaust fumes can  
escape freely without obstruction from your clothing. While  
working, grip the brush cutter firmly with both hands.  
Stand in a stable position on your feet. Keep the grips  
clean and dry. Do not use the brush cutter while standing  
on a ladder or other unstable support. You should always  
be able to control your balance. Never use the machine  
under extreme weather conditions or in bad weather (very  
low temperatures, very hot, humid climate, fog, rain, wind,  
etc.). Keep all parts of your body and clothing away from  
the blades during startup or when the engine is running.  
During use, keep the work zone in front of you. Never cut  
walking backwards as you cannot see possible hazards.  
Do not put the machine down with the engine running.  
Never leave the machine alone. Never raise the brush cut-  
ter above knee level during cutting.  
Health precautions  
Avoid prolonged use. Noise and vibrations may be  
6
dangerous. Prolonged use of the machine or other  
equipment expose the operator to vibrations that can  
cause the White Finger Syndrome (Syndrome of  
Raynaud). This could reduce the sensitivity of the hands in  
distinguishing different temperatures and cause a general  
numbness. The operator should therefore check the con-  
ditions of the hands and fingers if the machine is used  
continuously or regularly. If one of the symptoms should  
appear, consult a doctor immediately. Prolonged use of  
the machine or other equipment can cause discomfort,  
stress, fatigue, hearing damage. Wear suitable hearing  
protection when using the machine. Correct and scrupu-  
lous maintenance can also help to protect you further  
from the risk of noise and vibration.  
Avoid contact of the eyes and skin with any oil or  
7
fuel. Do not inhale the gasoline fumes as they are  
toxic. Do not start or run the motor in closed or poorly  
ventilated places. The exhaust fumes are poisonous to  
breathe and can be asphyxiating and even fatal.  
Adjust the shaft fastening buckle so that the blade  
12  
or line cutter head are parallel to the ground. The  
connection point should be held in the original position so  
as to avoid unbalancing the shaft.  
Work zone  
Examine the work area and be careful of any haz-  
ards (such as roads, driveways, power lines, hang-  
8
Precautions for carrying the machine  
ing tree limbs, etc.). Take special care when working on  
sloping terrain. Before use, remove any rubbish from the  
work area such as rocks, broken glass, ropes, metal  
parts, cans, bottles and any foreign body that could  
become entangled with rotating parts or be projected  
dangerously at a distance. Take account of possible haz-  
ards that may not be perceived because of the noise of  
the machine. Make sure there is someone in the vicinity  
within safe calling distance in case of accident.  
Never carry the brush cutter, even for short  
13  
distances, with the engine running. Switch off  
the engine and carry it with the blade or nylon  
string head facing backward. For your safety, dur-  
ing transport and storage, always protect the  
blade with the guard supplied with the machine  
(see "Protection for transport"). When you trans-  
port the brush cutter in a motor vehicle, place it in  
a stable fixed position so that no fuel leaks out. We  
recommend emptying the fuel tank whenever you  
transport the machine.  
During use  
During use and for a few minutes after switching off

Fire prevention precautions  
on which the cutting device is fastened are very hot. The  
muffler and its guard are very hot during use and after the  
engine has been switched off, even with the engine run-  
ning at minimum speed. Contact can cause burns. Do  
not touch these parts if they are still hot.  
Never work with the brush cutter in the presence  
14  
of fire or spilled gasoline. If you have spilt it on your-  
self, change your clothes at once. Keep the machine  
clean by removing any grass cuttings, leaves, excess oil to  
reduce the fire hazard. Engine exhaust fumes can get very

hot and may contain sparks. Do not use the machine  
near inflammable material. The muffler gets very hot during  
use and remains hot for some time after switching off the  
engine. This also applies at idle speed. Take every precau-  
tion to reduce the fire hazard, especially in the presence of  
inflammable materials or gas. Start the engine at a dis-  
tance from the filling site and far away from any fuel tanks  
(at least 3 meters).  
with worn teeth can create problems in cutting and can  
cause KICKBACK, that is, a violent thrust on the front of  
the machine caused by the impact of the blade against  
wood or solid foreign bodies. This kickback can cause  
loss of control of the machine. Never sharpen a damaged  
blade: replace with a new one. Kickback can also occur  
when cutting with any type of blade in the hazardous  
zone (see I3). Do not let the blade cut in the risk sector to  
prevent kickback.  
When filling the fuel tank, dry any spilled fuel. Never

Precautions for operating a split shaft machine  
hot to avoid the risk of fire (let the engine cool off before fill-  
ing the tank). Fill the tank outdoor, far from flames or  
sparks. Do not take the cap off the tank with the engine  
running. Open the cap on the tank carefully to eliminate  
any excess pressure. After fueling, close the cap tightly.  
Take care not to spill any fuel. The fumes produced by the  
fuel can cause an explosion or fire. Gasoline is highly  
inflammable: before going near any type of fuel, put out  
your cigarette, pipe or cigar. Do not smoke or take  
sources of heat or sparks near the fuel. Never refuel near  
or over inflammable objects (dry leaves, etc..).  
If your machine is a split shaft model, that is to say  
17  
composed of a power unit (1) and an attachment  
(2), you must furthermore conform to the following rules:  
Never turn on the machine without an attachment cor-  
rectly fitted. Before every start check the attachment/shaft  
joint and the attachment to be assembled correcty and in  
excellent conditions.  
This manual is meant to be: the manual of the power unit;  
the manual of the string head/grass blade attachment  
and, moreover, if not explicitly stated otherways, it refers to  
the two units as already assembled in ther proper way  
(see chapter E6. attachments fitting/removal).  
When using other attachments, carefully read their instruc-  
tion manual and make sure you understand them before  
using . This machines allows the fitting of the following  
attachments only: UNIVERSAL OUTDOOR ACCES-  
SORIES - Hedge Cutter Attachment.  
Kickback  
Machines equipped with blades may produce a  
16  
violent kickback on contact with solid bodies. The  
force of the kickback can cause the operator to lose con-  
trol of the machine. The blade is capable of amputating  
arms and legs. Always work with a sharp blade. A blade

This device serves to prevent accidentally press-  
ing the throttle trigger (fig. A no. 3). In fact, the  
trigger (fig. A no. 3), can only be pressed if the  
safety lever is pressed at the same time (fig. A no.  
19). By means of 2 separate springs, upon  
releasing the grip, the throttle trigger (fig. A no. 3)  
and safety lever (fig. A no. 19) return automatically  
to their original positions.  
This very important safety device (fig. A no.19)  
prevents any objects that come into contact with  
the cutting device, or the grass itself, from flying  
up and striking the operator.

Engine stop device  
This device, fastened to the machine, ensures a  
minimum distance between the operator and the  
cutting device during use, and prevents the  
machine from striking and injuring the operator if  
the blade hits a hard surface (fig. A no. 20).  
Turn the stop button Stop (fig. A no. 7) to O /  
STOP to stop the engine. To make sure this but-  
ton works properly, start the engine and check  
that it stops when the Stop button is turned to  
the Stop position.

Harness  
CAUTION! It is very important to famil-  
iarize yourself with the release mecha-  
nism. In case of emergency you need to be  
able to release the machine quickly.  
The harness is equipped with a fasten-release  
mechanism. The harness enables the operator to  
support the machine during use (see “Safety pre-  
cautions”, B7).

Do not use any other type of fuel than the  
type recommended in this manual. This  
Clean the area around the fuel cap before remov-  
ing it, to prevent any impurities from contaminat-  
ing the fuel. Take the cap off the fuel container  
carefully. Unscrew the cap on the fuel tank and fill  
it with the necessary quality, using a funnel.  
During use, to prevent problems in starting the  
engine again, we strongly recommend that you  
avoid letting the fuel run out in the tank.  
machine is equipped with a two-stroke engine  
and should therefore be fueled with a mixture of  
unleaded gasoline (with a minimum octane rating  
= 90) and fully synthetic oil specific for two-speed  
engines that use unleaded gasoline in the propor-  
tions indicated in the table on the cover, fig. D.  
Control the specifications of the oil shown  
on the package; the use of oil lacking the  
specifications expressly indicated in this manual  
could cause serious damage to the engine!  
Fuel storage  
14 15  
Store the fuel in a cool, well-ventilated  
place, in an approved fuel storage container.  
To obtain the best mixture, pour the oil into an  
approved container first, followed by the gasoline,  
and shake the container well (every time you take  
fuel out of it).  
The characteristics of the mixture tend to deteriorate  
in time, so you should only prepare as much mixture  
as you are going to need (the use of deteriorated  
fuel can seriously damage the engine).  
Never store the engine with fuel in the tank in a  
poorly ventilated place where the fumes produced  
by the gasoline could propagate and reach a fire,  
candle, burner or furnace pilot light, water heater,  
dryer, etc. Never store excessive quantities of  
fuel.  
E. Assembly/disassembly  
E1. Delta grip  
Safety guard extension (exclusively for use  
with nylon string head)  
• The extension (B) should be installed only for  
use with the nylon string head, with the aid of  
the string cutter blade (L), that regulates the

Your machine can be equipped with a low emis-  
sion carburetor. We recommend that you have  
any adjustment of the carburetor made exclusive-  
ly by an authorized service center, which disposes  
of special equipment for ensuring the best per-  
formance with the lowest emissions. To adjust the  
speed to the minimum, turn the screw marked (T)  
as shown: With the engine running and well  
warmed up, turn the screw (T) gently clockwise,  
until the engine rotates at regular speed (stead  
noise), without the cutting devices in motion. If  
All the above adjustments should be made  
with the cutting devices correctly installed.

Periods of prolonged disuse  
See "Environmental information".  
H1. After every use  
In order to avoid overheating the motor, remove  
any dust and dirt from the slots on the cylinder  
cover and finds of the cylinder using a wooden  
scraper. Store the machine in a dry place.  
If you use the machine in an exceptionally  
dirty or dusty environment these operations  
should be carried out more often.  
After 25 hours of use  
Remove the filter as shown in the figure and clean  
it using a gentle jet of compressed air. For more  
thorough cleansing, you can wash it with soapy  
water.  
H2. Replacement of nylon string  
To replace the reel of string, press both the  
release pawls indicated by the arrows, remove  
the empty reel, unroll any string left and rewind  
the new string. Open the original package of  
string and insert the ends of the two strings in the  
eyelets on the reel, then wind the strings com-  
pletely on the reel in the same direction and fas-  
ten the end of each string in the 2 opposite  
grooves. Replace the reel in its housing and  
thread the ends of the strings in their bushings.  
Pull each string so that about 15 cm comes out  
on each side. Reassemble the nylon string head  
as shown. If the reel becomes excessively worn,  
replace it with a whole new reel.  
After 50 hours of use  
Add some high speed gear grease in the gearbox  
through hole (C). Remove and clean the spark  
plug (set the space between the electrode at  
0.5/0.6 mm). Replace if excessively encrusted. In  
case of excessive encrustation check the carbu-  
retor adjustment, the percentage of oil in the fuel  
mixture and make sure the oil is of excellent quali-  
ty and suitable for two-stroke engines.  
After 100 hours of use  
Replace the spark plug.  
Every three months  
Contact your Service Center for a complete over-  
haul, replacement of the fuel filter and cleaning of  
the parts inside the machine. This will reduce the  
possibility of unexpected problems and will

Cutting techniques  
Wait until the engine is running at minimum  
speed before moving the machine from one  
section to another.

against the ground: release the throttle trigger to  
reduce the engine speed to less than 8000 rpm.  
Tap gently on the ground with the button (A) as  
shown in the figure and the string will come out  
automatically. Accelerate again. If the string does  
not come out make sure there is still some left  
and try again.  
Cutting and trimming grass borders with the  
nylon string head  
Cutting with the nylon string head is suitable for  
light jobs like trimming borders and cutting the  
grass around trees.  
Mowing  
To prevent damage to your lawn or the cutting  
mechanism, keep the string parallel to the ground  
but avoid contact with the terrain.  
Trimming borders  
I2. Thinning grass with the grass cutter blade  
2 16  
Angle the nylon string head keeping it a short dis-  
tance from the ground. Cut using the end of the  
string. Do not press the string against the material  
to be cut.  
The grass is cut with swinging motions from side  
to side, maintaining the blade parallel to the  
ground. During the right to left swing the grass is  
cut, while the backswing must be made without  
using the blade.  
KICKBACK can occur when cutting is done with  
the risk sector of the blade; we recommend cutting  
with the rest of the blade. Take care that the cup  
supporting the blade just grazes the ground. This  
will prevent the blade from touching the ground.  
I1. Drawing out the string  
During cutting, the nylon string wears naturally  
causing an increase in the speed of the engine  
and a reduced cutting capacity. When this hap-  
pens, to bring out more string bump the head
