8 PREPARING TO WORKEN
CHECKING THE MACHINE
Before starting work please:
– check that all the screws on the machine andthe cutting device are tightly fastened;
– check that the cutting device is undamagedand that the 3 or 4-point metal blades (if fitted)are properly sharpened;
– check that the air filter is clean;– check that the protection devices are well fas-
tened and working efficiently;– check the handgrips are well fastened.
PREPARING THE FUEL
This machine is fitted with a two-stroke enginewhich requires a mixture of petrol and lubricatingoil.
Using petrol alone will dam-age the motor and will cause for invalidation ofthe warranty.
Only use quality fuels andoils to maintain high performance and guaranteethe duration of the mechanical parts over time.
• Petrol characteristics
Only use unleaded petrol with a fuel grade of atleast 90 N.O.
Unleaded petrol tends tocreate deposits in the container if preserved formore than 2 months. Always use fresh petrol!
• Oil characteristics
Only use top quality synthetic oil specifically fortwo-stroke engines.
Your dealer can provide you with oils which havebeen specifically developed for this type ofengine, and which are capable of guaranteeing ahigh level of protection.
The use of these oils makes it possible to pre-pare a 2% mixture, consisting in 1 part oil to 50parts petrol.
In the event that no specific oil is available, it is
IMPORTANT
IMPORTANT
IMPORTANT
possible to use a mineral lubricating oil forengines (class FA or FB), where in this case themixture must be 4%, i.e. 1 part oil and 25 partspetrol.
• Preparation and preservation of the fuelmixture
Petrol and the fuel mixture are highly inflam-mable!– Keep the petrol and fuel mixture in homolo-
gated fuel containers, in safe place, awayfrom any flames or heat sources.
– Never leave the containers within the reachof children.
– Never smoke whilst preparing the mixtureand avoid inhaling the petrol fumes.
The chart indicates the amount of petrol and oilto use to prepare the fuel mixture according tothe type of oil used.
To prepare the fuel mixture:
– Place about half the amount of petrol in ahomologated tank.
– Add all the oil, according to the chart.– Add the rest of the petrol.– Close the top and shake well.
The fuel mixture tends toage. Do not prepare excessive amounts of thefuel mixture to avoid deposits from forming.
Keep the petrol and fuel mix-ture containers separate and easily identifiable toavoid the mistake of using one in place of theother.

ENUSING THE MACHINE 11
To respect people and the environment:
– Try not to cause any disturbance.– Scrupulously comply with local regulations
and provisions for the disposal of wastematerials after sawing.
– Scrupulously comply with local regulationsand provisions for the disposal of oils,petrol, damaged parts or any elementswhich have a strong impact on the environ-ment.
Prolonged exposure tovibrations can cause injuries and neurovas-cular disorders (also called “Renaud’s syn-drome” or “white hand”), especially to peoplesuffering from circulation disorders. Thesymptoms can regard the hands, wrists andfingers and are shown through loss of sensi-tivity, torpor, itching, pain and discolouring ofor structural changes to the skin. Theseeffects can be worsened by low ambient tem-peratures and/or by gripping the handgripsexcessively tightly. If the symptoms occur,the length of time the machine is used mustbe reduced and a doctor consulted.
Always wear suitableclothing when using the machine. Your deal-er can provide you with all the information onthe most suitable accident-preventiondevices to guarantee your safety.
USING THE WEBBING (Fig. 12)
The machine must alwaysbe used connected to the webbing worn cor-rectly. Frequently check the efficiency of thequick release mechanism used to quickly freethe machine from the belts in case of danger.
The webbing must be put on before connectingthe machine to the special coupling and thebelts must be adjusted to suit the operator’sheight and stature.If the machine has more than one coupling hole,use the most favourable point for keeping themachine balanced when working.
�! WARNING!
�! WARNING!
�! WARNING!
Always use webbing suited to the weight of themachine and the cutting device used
– the single or double belt models can be usedfor machines weighing less than 7.5 kg fit-ted with the cutting line head or 3 or 4-pointblades;
– the double belt model must be used formachines weighing more than 7.5 kg fittedwith the saw blade (if permitted).
• Single belt “MONO” models
The belt (1) must go over the left shouldertowards the right hip.
• Double belt models
The belt (2) must be worn with:– the padded part and snap-hook coupling on
the right;– the release in front;– the belt cross-over on the operator’s back.
The belts must be tensioned so that the load isevenly distributed on the shoulders.
• “FLEX” models
Wear the webbing harness like a normal back-pack.Tension the belts so that the load is evenly dis-tributed on the shoulders, fasten the waist beltand connect the elastic to the plate.
USING THE MACHINE
When working, themachine must always be firmly held in bothhands, keeping the power unit on the right ofthe body and the cutting group below the lineof the belt.
Stop the engine immedi-ately if the blade stops during sawing. Alwaysbeware of a kickback, which could occur if ablade encounters a solid object (logs, roots,branches, stones, etc.). Do not touch the

ground with the blade. Kickbacks causeblade recoils that are difficult to control, so asto cause loss of control of the machine, com-promise operator safety and cause damageto the machine itself.
Before tackling a mowing job for the first time itis advisable to gain the necessary familiarity withthe machine and the most suitable cutting tech-niques, finding out how to wear the webbing cor-rectly, firmly gripping the machine and makingthe movements required by the job.
• Choosing the cutting device
Choose the most suitable cutting device for thejob to be done, according to these general indi-cations:
– the 3-point blade is suitable for cuttingbrushwood and small shrubs up to 2 cm indiameter;
– the 4-point blade is suitable for cutting resist-ant grass over large surfaces;
– the cutting line head can eliminate tall grassand non-woody vegetation near fences, walls,foundations, pavements, around trees, etc. orto completely clean a particular area of thegarden;
– the saw blade (if permitted) is suitable for cut-ting resistant bushes, shrubs and small treeswith a trunk up to 6 cm.
WORKING TECHNIQUES
a) 3-point blade (Fig. 13)
Start cutting above the undergrowth and thenmove down with the scything blade so as to cutthe brush into small pieces.
b) 4-point blade (Fig. 14)
Proceed using the machine as a traditionalscythe, with a circular movement of about 60-90°, thus moving outside the undergrowth, andso on.
c) Cutting line head
Use ONLY nylon lines. The�! WARNING!
use of metal lines, plasticised metal linesand/or lines not suitable for the head cancause serious injuries and wounds.
During use it is advisable to stop the engine peri-odically and remove the weeds wound round themachine, so as to prevent the drive tube fromoverheating due to the grass caught under theguard.
Remove the caught-up grass with a screwdriverto allow the rod to be properly cooled.
Do not use the machinefor sweeping, tilting the cutting line head.The power of the engine could throw objectsand small stones 15 metres or more, causingdamage and injuries to people.
• Cutting in motion (Scything) (Fig. 15)
Proceed at a regular pace, with a circular motionsimilar to a traditional scythe, without tilting thecutting line head during the operation.
First try cutting at the right height in a small area,so as to then achieve a uniform cutting heightkeeping the cutting line head at a constant dis-tance from the ground.For heavier cutting it can be useful to tilt the cut-ting line head by about 30°.
Do not work in this way ifthere is the possibility of causing objects tobe thrown, which could harm people and ani-mals and cause damage.
• Precision cutting (Trimming)
Keep the machine slightly tilted so that the lowerpart of the cutting line head does not touch theground and the cutting line is at the requiredpoint, always keeping the cutting device at a dis-tance from the operator.
• Cutting near fences/foundations (Fig.16)
Slowly approach the cutting line head to fences,posts, rocks, walls, etc. without hitting themhard.
�! WARNING!
�! WARNING!
If the line strikes a solid object it could break orbecome worn; if it gets tangled in a fence itcould break abruptly.
In any case, cutting around pavements, founda-tions, walls, etc. can cause greater wear thannormal in the line.
• Cutting round trees (Fig.17)
Walk round the tree from left to right, approach-ing the trunks slowly so as not to strike the treewith the line and keeping the cutting line headtilted forward slightly.Remember that the nylon line could lop or dam-age small shrubs and that the impact of thenylon line against the trunk of bushes or treeswith soft bark could seriously damage the plant.
• Adjusting line length when working (Fig. 18)
This machine is fitted with a “Tap & Go” head.To release more line, tap the cutting line headagainst the round with the engine at top speed:the line will be released automatically and theknife cut off the excess length.
d) Saw blade (if permitted) (Fig. 19)
Use of the saw blade isprohibited on machines marked with the spe-cific symbol (see chap. 2 n° 6). When usingthe saw blade, where permitted, the specificguard must always be fitted. The blade mustalways be well sharpened to reduce the riskof kickback.
When felling small trees,estimate the direction in which the cut treewill fall, also taking the wind direction intoconsideration.
To get a good result when felling small trees, thecut must be made with a rapid movementtowards the branch or trunk to be cut, with theengine at maximum revs.
�! WARNING!
�! WARNING!
Do not use the right-hand area of the bladebecause there is a high risk of kickback or theblade seizing up, due to the direction of rotation.
END OF OPERATIONS
When you have finished your work:
– Switch off the engine as indicated above(Chap. 6).
– Wait for the cutting device to stop and fit theblade guard (if 3 or 4-point blades of sawblades are used).
