COMPOSANTS ET ÉLÉMENTS MOTEUR RM80 cc.
MOTEUR
Cepropulseuraétéimaginéetconstruitspécialement
pour le Paramoteur. Monocylindre à 2 temps de
faible cylindrée (80 c.c.) et à forte compression,
refroidissement à air forcé qui maintient la
température du groupe moteur à son niveau idéal
et hautes prestations. Utilisez de l’essence super
avec un mélange d’huile synthétique à 2 %(rapport
de 50 pour 1) par litre. L’excès ou le manque d’huile
peuvent endommager le fonctionnement du moteur.
Ilest importantde toujoursutiliser lamême proportion
d’huile, de ne pas mélanger les huiles entre elles
et on recommande de NE PAS utiliser d’essence
mélangée stockée depuis plus de 50 jours, dû à ce
que les molécules de l’huile et de l’essence peuvent
se dissocier. De la même manière on recommande
de filtrer l’essence à la sortie du réservoir, lorsqu’on
va prendre de l’essence (PHOTO 24).
Les deux marques que recommandent PAP sont
CASTROL TTS PREMIX et MOTUL 700.
RODAGE DU MOTEUR
Chaque client reçoit le moteur avec approx. 15-20 min. de rodage au sol, où chaque unité se
règle et s’adapte en carburation au niveau de la mer. On vérifie également que l’hélice soit
parfaitement équilibrée, ainsi que les autres composants du moteur (embrayage, réducteur,
etc...). On recommande que le moteur soit rodé durant 15 min. au-dessus de 5000 TPM (pour ne
pas endommager le mécanisme d’embrayage) avant de commencer le vol. Durant les premières
heures de vol il ne faut pas faire tourner le moteur sans arrêt à plein régime (on conseille des
vols d’après-midi avec une légère brise ou du vent météorologique pour aider le moteur). On
considère le rodage complet après avoir utilisé le moteur (au sol et en vol) pendant 10 heures
avec de l’essence sans plomb mélangée à 2%. Ce pourcentage ne connaîtra jamais de variations
durant la vie du moteur.
Un moteur bien rodé peut augmenter sa longévité de 100% et diminuer les problèmes
mécaniques. Dans le cas contraire, il existe de hautes probabilités que le moteur
s’endommage de façon irréversible durant les premières heures.
Le régime moteur devra varier fréquemment et augmenter progressivement. Ne pas donnez
de coups de gaz continuellement, au risque d’exposer l’embrayage centrifuge à des
charges anormales. Avant chaque démarrage il est conseillé de contrôler minutieusement la
fonctionnalité de toutes les parties mécaniques ainsi que de tous les écrous, vis et boulons.
En respectant les 15 premières min. de rodage, il est conseillé de voler les heures suivantes,
à condition de ne pas faire tourner le moteur à plein régime trop longtemps. Pour les pilotes
lourds, il est conseillé de roder le moteur au moins 1 heure au sol avant de voler.

Les révisions et contrôles durant cette phase sont détallées dans la section Entretien, 10 premières
heures. Si l’on ressent une perte de puissance, celle-ci peut être due à une carburation pauvre
qui à son tour est due à un mauvais réglage ou à cause d’impuretés dans le filtre du carburateur.
Dépendant de l’altitude à laquelle vous vous trouvez, vous devrez réajuster un peu la carbura-
tion, pour éviter qu’elle ne soit trop pauvre. Il vaut toujours mieux un moteur à mélange riche que
pauvre ; au moins on évite les problèmes de grippage. Après 1 heure ou 2 de vol, il est important
de vérifier le serrage des vis de la culasse (voir tableau de couple de serrage) Normalement
le desserrage de la culasse se manifeste par des «pétarades» sourds ou des tâches d’huile ob-
servées quand on enlève la carcasse de refroidissement du cylindre.
DÉMARRAGE DU MOTEUR
Il est interdit de démarrer le moteur sans hélice et sans réducteur. Un moteur à 2T est léger et
sans la charge de ces éléments, il atteint sa vitesse de rotation maximum en une fraction de
seconde. Il n’existe pas de limiteur de TPM. Les composants mécaniques sont construits pour
résister uniquement à des régimes du moteur (TPM) prévus avec l’hélice.
Un régime trop puissant peut être catastrophique pour le moteur. Pour chauffer le moteur, au
moins 1 à 2 minutes sont nécessaire. Durant ce laps de temps, le moteur va accélérer progres-
sivement avant d’obtenir la température (idéale) de fonctionnement. Evitez que le moteur tourne
à moins de 400 TPM, car à une vitesse réduite les massues de l’embrayage s’ouvrent et se fer-
ment continuellement par manque de force centrifuge et à cause des coups sur la cloche il est
possible que les ressorts et même l’embrayage lui-même se cassent de façon irrémédiable.
Pour savoir combien d’essence vous devez ajouter chaque fois que vous allez démarer le moteur
(à froid où quand il n’a pas été utilisé depuis longtemps) il vous suffit de pousser avec le doigt sur
la soupape-bouton installé sur la membrane du côté extérieur du carburateur, et en même temps
sur la poire d’amorçage du circuit d’essence.
Avec un peu de pratique vous utiliserez la technique adéquate à chaque type de démarrage
que le moteur soit froid ou chaud. On peut utiliser la poignée du ‘starter’ (manette de l’air) du
carburateur, mais ce système est conçu pour les jours de grands froids en en pratique il ne
s’utilise presque jamais.
RÉDUCTEUR ET TRANSMISSION
Le réducteur d’engrenages dans un bain d’huile est très efficace et fiable. De plus, il réduit le
bruit du moteur considérablement. Son rapport est de 3,65 pour 1. Ce réducteur n’a besoin
d’aucun entretien ni réglages et il faudra juste vérifier le niveau d’huile toutes les 100 heures.La
transmission du vilebrequin au réducteur se fait par l’intermédiaire d’un embrayage centrifuge
à sec qui permet à l’hélice d’être arrêtée au ralenti. Il n’a pas besoin d’entretien.La quantité
d’huile est de: 16 ml. de SAE 140.
IMPORTANT: Avant de démarrer, vérifier que le câble du gaz ne soit pas bloqué.
Pour cela, il est suffisant de mettre les gaz quelques fois à fond.
ATTENTION: Lorsqu’on démarre en accélérant, il est très important de lâcher le
gaz avant que le moteur ne monte en régime.

RÉGLAGE DE LA CARBURATION
Le moteur est réglé de façon optimale au départ d’usine. Si vous
n’êtes pas complètement certains de dominer ces aspects, nous
vous recommandons de ne pas modifier la carburation, car ce
type de carburateurs sont en principe très stables à toutes alti-
tudes et températures.
Un moteur riche vibre et consomme de trop et un moteur pauvre
est plus régulier mais surchauffe plus vite et est dangereux, car
il peut endommager le moteur. En général, on parle de “trous”
dans le carburateur.
COULEUR DE BOUGIE JAUNE / GRISE CAFÉ AU LAIT MARRON / NOIRE
CARBURATION PAUVRE CORRECTE RICHE
CARBURATEUR WALBRO
Dans certains cas il peut être nécessaire un changement de la carburation ‘saisonnière’,
particulièrement lorsqu’on change d’altitude, mais il est conseillé de procéder au réglage par
un expert. Le réglage de carburation dans le régime bas-moyen est effectué avec la vis la
plus longue 1, (PHOTOS 25 et 25B). Vissée vers la gauche (ouvrir), elle s’enrichit, et vers la
droite (fermer), elle s’appauvrit. Le réglage standard est de 1 1/2 tours en partant de la posi-
tion fermée et ensuite on ferme l’équivalent de 5 minutes à l’échelle d’une montre.
Si la carburation minimum est pauvre, le démarrage est difficile et si l’on accélère doucement
le moteur peut s’éteindre. Si la carburation minimum est très
riche, on sent des vibrations à l’accélération, le moteur descend
lentement en TPM et la fumée d’échappement est excessive.

MANUEL D´UTILISATION
It needs to be conscious that the motor can stop, have a breakup or to go off in any
moment. This could lead a crash to the ground or a landing in hostile areas with possible
damages/death of the pilot or other people. The ultralight moved by this motor must fly in
permitted spaces to it, not to fly above a crowd of people, inhabited centers, zones that
have difficult or void landings, not to fly above zones of water or where is possible to drown.
It always needs to have in mind that the motor can go off or breakup, therefore to consider
a possible landing of emergency for every situation..
This manual describes the motor. For its installation, use and control, you compare also
the attached user manual of the ultralight: Paramotor, Mosquito or Trike... If used in other
applications, cannot be guaranteed the correct operation.
This motor is not certified. It is not a motor with guarantees or aeronautical certifications. Its
construction is destined to experimental and not certified aircrafts.
Some zones for particular atmospheric conditions as pressure, temperature, damp can bring
to a different operation of your motor. Before beginning every flight, you test on the groud the
motor and verify that it doesn’t have an anomalous behavior.
Start the engine in a plain surface, free from stones, sand or small parts that could be
aspirated by the propeller. Be sure that the flow of air pushed by the propeller not lead
damage to anybody. In any moment the motor is running (testing on the ground, take-
off, landing) watch out that nobody draws near to the propeller in rotation. A good safety
distance is 50 meters for all directions of projection of the propeller and 20 meters for the
others directions.
Not use the motor that has not followed a correct maintenance or not correctly been used
in the time or if you know that is not under perfect conditions.
The use of not original spare-part and not recognized by the Vittorazi, can make the motor
dangerous and immediately hands term to the validity of the warranty. Vittorazi doesn’t
assume any warranty for that motor that are used with not original parts or not recognized,
modified or that have had an improper use.
Changes not authorized to the motor, to the reduction, to the propellers can reduce safety
and reliability of the aircraft. In the case you have to intervene on the motor we invite you to
compare this manual with the help of your dealer Vittorazi and follow it as reference.
Before every use or test, check the conditions of the propeller and the tightening of bolts of the
propeller. If the propeller has received a hit and is damaged you avoid to use or to turn on the
motor. This can lead to an explosion of the propeller in rotation or to strong vibrations that will
revert in the motor with possible consequent breakups, loss of tightening of the bolts or strong
usuries of components.
Do never use the motor without propeller or without reduction drive group. This motor has been
projected for a determined and contained number of turns. Without propeller or reduction drive,
the motor reaches a number of turns for which has not been calculated. In few second there is
risk of explosion of the motor.
2.WARNING

Be sure to possess a suitable and guaranteed propeller by Vittorazi for your motor.
3.GET READY FOR THE USE
3.1 PROPELLER MOUNTING
Attention: the propeller can be mounted in two opposite position in comparison to
the reduction drive, which only one is correct. Ask to the authorized dealer or to the
instructor, if you are not certain for the assemblage of the propeller.
Modelo Fly100evo: rotation propeller counterclockwise, considering the back view.
Push the propeller against the
reduction drive, untill to insert it
completely. Now gently screw the bolts
up to the end. Be sure that the bolt
are proper for the propeller, therefore
the threads of the bolts are inserted at
least 10mm in the hub. Now to tighten
the bolts of the propeller trying to get
the same pressure on every point,
picture 4.1. Not do exaggerate with the
pressure on the bolts, there is a risk to
crush the propeller, if in wood.
Have a maximum pressure of 4 -5 Nm,
if the propeller is in composite carbon.
Propeller in wood: once tightened
the propeller, it is opportune to check that the pich of the two blades is identical. If there is a
considerable variation among the two blades, this difference can be compensated through
the pressure of the bolts. If you don’t know this method of balancing, ask to an authorized
instructor or dealer. Check the tightening of the wood propeller every 3 hours of flight and
repeat the balancing.
(fig. 3.1)
The motor that you are going to use is a two strokes engine. It requires for the lubrication
an established percentage of oil/gasoline. When at the gas pump, always choose gasoline
unleaded 95 octanes. The percentages will be pointed out in the following paragraphs, “break-
in” 4.5 and “normal operation” chapter 4.
3.2 FUEL
The gasoline is an extremely inflammable and explosive substance. When you
prepare or in every moment you are close to the fuel (gasoline and oil), not smoke,
not provoke sparks or flames. Never fill the tank of your aircraft when the motor is
running. Position the tank of the fuel before starting the motor at least 10 meters.
Get Ready for the Use.
MANUEL D´UTILISATION

During the operation of decanting, mixing, filling, choose an open place, ventilated, clean
and away from dusts, sand, grass and everythings that can obstruct the passage of the
gasoline. If possible while filling the tank of the aircraft, filter the mixture. Be sure that the
tank for the transport gasoline, filter and funnel, is perfectly always clean.
We advise only oil of good quality certified and full synthetic (no oil semi-synthetic, no
mineral oil). We recommend the use of the following types of oil, already tested with success
on our motors: Motul 600, Castrol TTS, Valvoline Racing 2T.
Avoid mixtures prepared by the gas pump. A mixture had been prepared from 2-4 weeks
and left in a tank could separate (oil and gasoline), loosing the characteristics of lubrication
even if shaked before the use. Avoid to prepare a big quantity of mixture, when you are
already conscious to use only a part of it. Avoid use plastic tanks and consider it as
containers to transport, not left to deposit the mixture for days in the plastic tanks. We
dissuade the addition of liquids that increase the number of octanes.
In the first starting of the engine and every time the gasoline piper remains without fuel
(tank, pipe, primer bulb and carburetor), will need to fill the circuit before starting the motor.
To do that, it is necessary make pressure on the primer bulb of the gasoline and at the same
time, with care on the valve of the carburetor (indicated with the number 6 in the following
picture 4.5) up to the filling of the pipeline. It will be easy to see through a transparent
pipeline the gasoline that enters into the carburetor. For a good starting of the engine
when the circuit is empty or the motor is cold, need to enter just a few of gasoline in the
carburetor. This small quantity of gasoline, will work as starter/choke to the motor. Attention
if the quantity of gasoline that you push with the pomp to the carburetor is excessive, there
is the risks to flood the motor, even then to damage the pull starting.
The best starting of the motor Vittorazi is gotten without throttle or with a minimum of
throttle. If the circuit of fuel is on pressure and the motor is warm, it won’t be necessary to
make pressure on the primer bulb and valve.
3.3 STARTING AND TURNING OFF
Always watch out for the propeller during the starting and for whom could be nearby.
Many accidents happen before going to flight. On every test or warm-up, we suggest
to always wear the paramotor on your shoulder, to fast the harness, then to turn on
the engine with the pull or electric starter, ready however with the killing button to
stop the motor in every moment.
Important: often verify that the killing button is working. Sometimes the killing
buttons can get jammed or during the time can stop working.
You softly get throttle in the first 30 seconds allowing to stabilize the carburetor and the motor.
Now you increase the number of turns (thin to 1/4 around of throttle) and let warm-up the motor
for 2-3 minutes to this constant speed. Finally get the motor for some second (15-20 seconds)
at full throttle. Now your motor is ready to the flight. These 3 minutes of warm-up also have to be
dedicated, thanks to your attention, to understand if the motor has some anomalous behaviors,
if there are unexpected vibrations or noises not desired.

MANUEL D´UTILISATION

4.5.1 A SIMPLE AND FAST CONTROL
Don’t have any experience or affinity with the motors?
Don’t worry, you follow step by step what we tell you in this paragraph. From years our
ambition is to furnish a simple product and accessible to everybody, trying to get simple
and effective solutions for who doesn’t have experience of adjustement of motor.
When you receive the motor, it has already pass a test of 15 minutes in the thrust-bench of
the factory, verifying the operation, the assemblage and the optimal carburetor setting.
3.5 CARBURETOR ADJUSTMENT
Carburetor setting Vittorazi Fly100evo
Screw L from 1/4 to 1/3 of turn
Screw H from 1+1/8 to 1+1/4 of turn
Idle RPM 2.000 - 2.200 RPM
In the chart are suitable the regulations L and H of the motor in the standard positions. These
regulations guarantee the modularity of the motor, the operating temperature and the correct
lubrication of all the organs of the motor.

2. Screw H or High speed
3. Screw of the throttle, open

4. Pressure plug
5. Lever of butterfly
6. Valve for the first filling of
the carburetor
If you choose to verify the carburetor setting proceed in this way: close completely the screw
L and H and then exactly open them with the standard setting. Remember: a strong pressure
(tightening) on these screws can irremediably damage the carburetor.
A simple verification of the carburation can be effected, following these indications. After having
started the motor in safety and warmed-up for some minutes (see paragraph for starting and
warm-up) can be done in the ground a control of the carburation.
- The motor has to maintain a constant idle and not to have the tendency to go off or to flood.
- When you pull the throttle fastly from the idle rpm, the motor has to immediatelyanswer without
going off or a lack of power.
- Simulating a cruise flight (about 1/4 or 1/3 of throttle), the motor will have to answer with a
regular thrust, smooth and not with hiccups or jumps of power.
- With max speed or max number of rpm (full throttle), the thrust has to be constant.
Chart 3.5

Attention: if the carburation of the motor (the quantity of gasoline that arrive to the
motor) is poor, therefore the opening of the screw is lower in comparison to the
indications of the chart, will probably occur breakups as seizures, overheatings,
fusions of the piston, precocious usury of the components.
A check of the carburation can be made, analysing the color of the electrode of the spark. A first
control can be done, at the end of the of break-in period, in the following way:
- If the electrode is brown the carburation it is correct.
- If the electrode is grey or clear the carburation is poor and you have to immediately seek the
cause, with the help of an authorized dealer/instructor.
- If the electrode is dark brown color or black the carburization is rich.
Watch out for the regulation of the screw H, because if this is too closed in comparison to
suitable values, you could have damages to the motor. Any damage will occur if the carburation
of the screw H is too opened (rich). In the doubt, therefore, is everytimes better to have a
carburation rich for the screw H.
4.5.2 CARBURATION. ONLY SKILLED PERSON.
The chapter or paragraph is reserved to the manufacture, dealer or center assistance
Vittorazi. If you are our collaborators, we invite you to write to our e-mail address and get
the integral version of the manual.
A phase of break-in executed with care, improves the duration and the performances
of the motor. The motor must be uses with attention in the first 7 - 8 hours of the
break-in (25 - 30 liters).
For the period of break-in, we indicate to move the screw High to a value of 1 turn+1/4
(rotation counterclockwise for 1/4 of turn) and to increase the quantity of oil in the fuel
up to the values pointed out by the chart 4.6.1. After 10 liters of break-in the screw High
could be closed with precision of 1/8 of turn, only if the motor doesn’t have smooth or
regular disbursement, as suitable in the following paragraph.
From our experience we allow to say, this will be the only time when you will have
to touch the screw High. Whenever the carburation will have a variation, it will be
enough to modfy the position of the screw Low. In these period of break-in, thanks to
your intervention on the screw H and to the increase of oil in the fuel, the motor will
enjoy of a good lubrication and of a lower temperature in comparison to the norm.
The performances of the motor won’t be optimal with these regulations, but you will
get a good break-in and a guarantee of duration for the organs of the motor. The first
starting of the motor must be made to the ground (on shoulder), warm up for some
minutes and pay attention to anomalous behaviors or noises. We recommend to
conclude in one day the first two phases of the break-in. Now follow the indications of
the chart 4.6.2.

BREAK-IN Vittorazi Fly100evo
Screw H 1 +1/4 of turn
First liter 4.0% or 25:1
From 2 to 30 liters 3.0% or 33:1
First liter of fuel The first phase is effected to the ground, it will last
around 15 minutes with a liter of fuel. Alternate least,
middle speed. No max speed. Pass to the following
phase, not leaving cool the motor completely.
From the second to the
10th liter of fuel
Effect flights or tests on the ground of max 15
minutes. Don’t use the motor at the same speed for
long time, an gradual acceleration and a release is
preferable. General check for bolts components.
From 10th to the 30th
liter of fuel
If necessary close 1/8 of turn the scew High. Always
with caution also flights of 30 mins. Maintain the
same percentage of oil pointed out in chart 4.6.1.
Repeat the controls.
Chart 3.6.1
At the end of the 30 liters of break-in the screw High could be in the position from 1+1/8 to
1+1/4 of turn and the percentage of oil decreased up to the values of the chart below 5.1.
We advise to replace the spark-plug (with the same type and gradation) at the end of the
break-in, because the quantity of fuel and oil in excess, could have decreases notably the
duration of it.

The electronic parts of the motor can be checked more hardly in the terms of wear
and tear. The spark-plug can last years or to stop working after some minutes (if the
shrewdness are not followed).
We advise: not to leave the motor idling for some minutes and accordingly to flood it.

5.SPECIFICATION AND TECHNICAL DATA
The maintenance of the components, is reserved to an authorized shop or dealer
Vittorazi, gifted in the meantime of qualified personnel in the mechanical, electronic and
aeronautical sector.
If don’t have competences or you are not certain of doing, limit to know well the manual
and to effect the suitable controls. Not risked you in any reparation that could make
become the motor dangerous.
The interventions of regular maintenance during the period of warranty must have the
relative invoice sent forth by the dealer. The interventions of maintenance made from a
workshop or from a personnel not authorized and not competent, will bring immediatley
term of the warranty.
6.MAINTENANCE

We advise: to correctly have the procedures of starting, in fact when the spark-plug receives too
gasoline from the carburetor, it stops temporarily working or sometimes definitely.
We advise to replace the spark-plug every 25 hours of use, so you will always have a good
coverage of operation.
The optimal distance of operation among the two electrodes of the spark-plug is of 0.80 mms.
Use a filler to establish this measure. When the spark-plug of the motor will be replaced, we
recommend to purchase the same identical type and gradation:
- the motor Easy100 uses a spark-plug NGK BR10ES
- the motor Fly100evo uses a spark-plug NGK BR9ES
The ignition coil can stop its function for a not conforming electric installation, for an electric
shock, for a bump, for the presence of strong and continuous vibrations or too much heat.
Our suggestion is to check every 25 hours of use, the cleaning of the carburetor
getting off the two sides of the carburetor, figure 1.
Clean the carburettor case blowing (gently with pneumatics) in the zone pointed out
by the circle and removing every small residue, figure 1-2.
Before getting off the carburetor analyzed well how the components are mounted.
Effect these operations with appropriate tools and in a perfectly clean bench or table.
Also the conditions of the membranes of the carburetor can be verified, show in
figure 1. The substitution of the membranes (possible to purchase a kit that includes
all the membranes and the gaskets carburetor) must be done after 100 hours of use
or once for year.
After some months the membranes of an unused motor can become stiff to contact
with the gasoline or can bend in the normal use, losing their peculiarity to oscillate
and to pump, not guaranteeing the correct operation of the carburetor/motor.

The control of the reed valve can be effected
after 25 hours of use therefore at the same
time of the carburetor cleaning. It will be
enough to get off the plate that contains the
reed valve and to check that the petals are
not broken or splintery. The substitution of the
petals is suggested at about 100 hours of use.
When the substitution will be done, watch out
for to position of the petals that will have
to be adherent to the surface of support. We
also recommend every 100 hours to replace
the gaskets of the reed valve that become stiff after time in contact with the fuel.
6.3 REED VALVE
(Pic. 6.3)
We advise to replace all the gaskets of tight after 100 hours of use of the motor:
gasket cylinder, carburetor, reed valve and silencer. Equally the o-ring: exhaust,
cylinder head.In the case the motor is not used for long period, we suggest to
verify the situation of the gaskets in contact with the gasoline and if necessary
to replace them.
6.4 GASKETS
The substitution of the soundproofing material of the silencer is recommended
every 25 hours of operation. Once replaced the soundproofing material you will
find again the same noise that the engine had when the motor was new. Separate
the silencer from the exhaust pipe, proceed getting off first the band of support
in steel, then the 2 nuts that unite the silencer to the muffler. Now remove the two
rivets that fix the silencer.
6.5 SILENCER
(Pic. 6.2)

MANUEL D´UTILISATION

Change now the soundproofing material worn out, cleaning the covers that seal the
silencer and continue to the assemblage of the new soundproofing material. Add as
denoted in the figure 6.5.1 and 6.5.2 a sealing paste, resistant to high temperatures
on the points of junction, fix two new rivets in the original position, change the gasket
silencer-muffler.
You now proceed bashful for the assemblage of the silencer. It will be possible
to purchase soundproofing material from the Vittorazi / dealer Vittorazi. If the
soundproofing material is purchased in a spare parts shop for car/motorbikes, you
don’t exceed with the quantity of soundproofing material, the effect after few hours
will be contrary to the desired one. We recommend to cut out a square of the same
dimensions of the material just replaced.
We advise to inspect at the end of every use of the motor the conditions of the rubber
mountings. In the case which one of these presents a crack or a detachment of the
rubber, immediately replace it. Reached the 100 hours, replaces the rubber mountings
of the motor (4pc) and the exhaust system (2pz). For a correct installation of the new
rubber mountings, you compare the paragraph 3.2.
6.6 RUBBER MOUNTINGS
A first control of the components of the pull starter is recommended to 25 hours. Just
removed the manual starting from the plate, the hooks/splines will be visible. Verify the
conditions and the slide of the hooks, lifting them with a finger. In every case add some
oil (for rusted bolts) on the pivots of sliding.
6.7 PULL STARTER FLY100EVO
(fig. 6.7)
The manual starting: as first operation loosen the knot that stop the handle of starting
and unthread the rope from the eyelet drives, suitable in figure 1.
Now positioning the rope in the hollow of the pulley as shown in figure 2, rotate the
pulley of wrapping clockwise, to lose the tension given by the spooling spring.
Unscrew the central bolt of 6mm, figure 3.

Lift the pulley with the help of a small screwdriver holding back the spooling spring that
is found under the pulley, figure 4 (you will avoid to go out this spring). If for distraction or
accident the spooling spring escapes, can be rearranged (provided of patience) manually
in the original position.
In the figure 5, freed the pulley, is shown the spooling spring.
Assemblage: add grease to the spooling spring and the pivot where slides the pulley,
then insert the pulley in the pivot drives.
Tight the screw of 6 mms, inserting lock-tight of medium resistance (if the washer creates
attrition with the pulley, turn upside-down the washer).
Position the rope in the hollow as in figure 2; turn the rope in the pulley wrapping, up to
fill it. Always maintaining the rope in the hollow, rotating counterclockwise unitill the origin
of the tension of the spooling spring begin; from this position rotate counterclockwise the
pulley of two complete turns, then maintain this position (hold the pulley) and return to
insert the rope in the eyelet drive, as in figure 1.
Finally always holding the pulley mark the rope with a pen in the adjacent zone the
structure, picture 6. Once made the sign, free the pulley and you can leave also the rope
reenters in the wrapping.
If necessary, for the remainder installation returned to the indications of the paragraph 3.8
