c. Replenishing of oil level
The reduction compartment will have already been filled with the appropriate amount of oil by
the engine manufacturer. However, after a certain number of hours, it may be necessary to
replenish the reduction compartment with appropriate oil:
ÖWithdraw the three bolts that maintain the reduction compartment onto the engine bloc and
bring the reduction compartment down;
ÖUnscrew the venting valve 1;
ÖDrain all the oil into a recipient and then slowly fill in oil of specification Mouwan Gear
80W90 (www.kripton.es) until 0,055 l./1,7 fl OZ (US) are in the compartment.
ÖFit the venting screw hand tight and put the reduction compartment back into place with the
three screws (make sure that they are well tightening).
ÖDispose of the used oil in a recycling container.
Attention: When placing the engine on a horizontal surface, take care not to damage the
electrical wiring of the starter mechanism.

i. Observation of the engine speed.
To determine the best possible transmission ratio, the use of a rev-counter is required for
observation of the speed limits.
Note: HE Paramotores offers as an accessory the following indicating instrument: Tiny-Tach
inductive rev counter.
Note: This instrument is operating via an integrated battery. At engine start the readings of
the connected sensors (inductive pick-up for engine speed (r.p.m.) will be displayed). This
display will remain on for 5 seconds after engine stop.
Attention: Pay attention to the manufacturer’s notes about connections and operation of the
instrument.
Attention: Use the original spark plug of 5 k resistance, so that the operation of the rev
counter is not impaired.
Wind at least three turns of the inductive cable between the ignition
coil and spark plug connector and secure it with a cable tie on the
ignition cable.
Attach the instrument with cable ties for highest visibility and lowest
inconvenience on the harness or chassis.
Attention: Use a vibration damping pad between the instrument
and tightening spot.
ÖSecure induction cable with cable ties on the frame.
Attention: The induction cable must be free of tensile stress;
stress could damage the cable or could result in the malfunctioning
of the cable and the instrument.
Warning: Before engine operation, read the Operator’s Manual.

v. The exhaust system
The exhaust system is designed as resonance system with an after muffler and represents a
tuned system with engine.
b. Fuel as media for engine operation
For engine operation a mixture of unleaded gasoline and oil is required in different quantities
varying upon the age of the engine and the model.
Amount of oil for a given amount of petrol:
R 80 R 120
Before 6 hours
(2 full tanks) 3,0 % of the amount of
unleaded petrol (U.P.) 95 with
fully synthetic 2 stroke oil (e.g.
CASTROL TTS).
3,0 % of the amount of U.P. 95 with fully
synthetic 2 stroke oil.
After 6 hours 2,5 % of the amount of U.P. 95
with fully synthetic 2 stroke oil. 2,5 % of the amount of U.P. 95 with fully synthetic 2 stroke oil.
ÖPour small amount of fully synthetic 2 stroke oil in a clean fuel container.
ÖAdd amount of unleaded petrol 95 to obtain a good mixture.
Attention: Too much oil in the fuel mixture could lead to engine trouble (e.g. cooking of the
exhaust valve).
Attention: Insufficient amount of oil in the fuel mixture could result in engine trouble (e.g.
piston seizure).
Confidencial HE Paramotores Página 10 30/03/2007

Warning: Do not try any different sorts of fuel. This could lead to engine damage to the
intake system.
Warning: When mixing fuel and fuelling do not smoke or allow naked flames. Petrol is highly
flammable and explosive under certain conditions.
Warning: Never perform mixing and fuelling in a closed room, handle fuel in well-ventilated
area only.
Note: Do not fill the fuel container to the top.
ÖShake well fuel container.
ÖPour fuel into fuel tank of the paramotor,
ÖClose fuel tank and fuel container immediately after fuelling.
Warning: Before each fuelling, shake well fuel container to ensure adequate mixing of the
gasoline with the oil.
Warning: Fuel the paramotor only when engine is not running.
Warning: Make sure that the fuel will not splash onto hot engine components or equipment.
Risk of fire and explosion!
Warning: Pay attention to the safety advice of the paramotor manufacturer!
Attention: Don’t spill fuel. Absorb spilled fuel with appropriate drying agent and ensure
ecological disposal.
Attention: Ensure that no contamination enters the fuel tank and the carburettor.
Attention: Unleaded fuel has a limited storage life. Store only the quantity of fuel in a
container which will be needed in the near future.

c. Engine tuning
i. Carburettor
The engine is carburetted in the factory before delivering; do not try to modify the carburetion
if you do not know how.
A "full rich mixture" produces more vibrations and increases consumption.
With a "lean mixture" the engine is more even but it gets overheated (usually there are
"blanks" in the carburetion). After 10 minutes of working, the spark plug will start to get dirty
with fuel waste.
spark plug colour yellow/grey hazel brown/light
brown brown/black
carburetion lean right rich
Diaphragm carburettor
In order to work properly, the diaphragms (pump and valves) must be kept wet by the fuel
mixture, after a long resting without fuel or after several working hours the diaphragms may
need to be replaced. In case of doubts please do get in touch with us. The replacement may be
necessary every year, the use of old diaphragms leads to an increasing leaning of the mixture
and piston seizure. In some cases it may be necessary a seasonal carburetion setting,
especially if you change of altitude, for such a setting please do turn to an expert.
idle too lean : Difficult start, while revving up the engine tends to stop
idle too rich : The engine abates while leaving it at idle for ten sec. and it
revs up slowly, excess of smoke.
R 80 and R120: Our carburettor is provided with a starter for the very
first starting (cold starting). Flip up switcher Ain position 2for starting,
in position 1for functioning.
The little hole Bat the front of the carburettor is used in the priming
process before starting a cold engine (Push cautiously! Go to section 2.
e.).
You can set the carburetion at the desired revs. By the long black
downward screw C. By turning it anticlockwise you rich the mixture,
while the opposite you lean it. The basic setting is between 1,5 and
1,7 turns from the shut position. The Cscrew must be turned very
gently, always verifying the cleanness of the "passage" (the point where
the nozzle of the idle enters the nozzle of the full, at about half revs.) in revving up. If the
engine pops, you tighten it; if it abates you loosen it.

temperature is too high (above 240°C), it may result in piston seizure.
Note: Dirt must be cleared at regular intervals to achieve the best cooling performance.
Attention: Keep your engine clean at all time!!!
Confidencial HE Paramotores Página 16 30/03/2007

e. Engine start and operation
Prior to engine start verify the following:
9Before starting the engine, ALWAYS check that the throttle cable is not jammed
open! Do this by squeezing the throttle lever and allow it to release sharply. Look
around and make sure there is no one nearby and SHOUT “Clear prop!” to warn
others of your intentions.
Warning: Never start the engine without the propeller!! A two-stroke engine has a low
mass and its maximum speed is reached in fractions of a second when no load is applied. It is
not equipped with a rev limiter and the mechanical parts are only designed to work at the
rotation speeds reached with the propeller. Exceeding this speed will have catastrophic effects
on the engine.
9Fuel tank full,
STARTING A COLD ENGINE
If the engine is being started for the first time, or it has run out of fuel you will need to prime
the fuel system. Gently press the short, fitted wire prod through the hole in the centre of the
plate on the propeller side of the carburettor whilst simultaneously squeezing the pump bulb.
This allows you to push fuel through the fuel filter and into the carburettor. Squeeze the bulb
just once and watch the fuel pass through the clear filter. Stop, pull the wire prod back and
gently squeeze the bulb again. The carburettor is primed. When starting a cold engine pull the
choke wire towards you, then start the engine and wait until it stops running. Then return the
choke wire to the neutral position and start the engine again using a little throttle then let it tick
over until warm. The engine will normally start without any problems unless
the outdoor temperature is very low. In this case repeat the use of the choke.
Note: To avoid damaging the starter mechanism, always use the starter as follows: hold the
starter handle with one hand, brace yourself against the frame with the other and gently pull
the starter feeling for the point of maximum resistance. Once there, give the starter cord a
short sharp pull. Normally the engine will start up immediately. If the engine does not start,
don’t keep pulling the starter, it will not help and it could even be dangerous. Save your energy
and find the source of the problem. It is nearly always an excess of fuel – the engine has been
flooded. Unlike a lot of paramotor engines the R 80 has it’s spark plug “head up” so it’s not
prone to flooding. Over zealous use of the fuel primer pump will, however, flood it and it won’t
start no matter how many times you pull the cord (!) If the engine has become flooded, simply
remove and wipe clean the spark plug. Tip: use a cigarette lighter to burn off the excess fuel on
the spark plug
STARTING A WARM ENGINE
Follow the same procedure as before but do not use the choke.
The engine needs to reach its working temperature – allow it to warm up for at least a minute
before revving it.
f. Stopping the engine
Press the Kill switch button for more then 3 seconds.
Warning: If not, you engine will restart.
Confidencial HE Paramotores Página 17 30/03/2007

g. Running in procedure for the engine
R-80: For the first two tanks of fuel, the engine should be run in with 2,5% of the amount of
unleaded petrol (U.P.) 95 with fully synthetic 2 stroke oil (e.g. CASTROL TTS). The engine
should be run in for approx 30 minutes before you start flying and during the first 5 minutes do
not use full throttle. The engine will be fully run in once it's consumed 20 litres of fuel, the mix
then put bring the mix to 2,2%.
R-120: For the first two tanks of fuel, the engine should be run in with 3,5% of the amount of
unleaded petrol (U.P.) 95 with fully synthetic 2 stroke oil (e.g. CASTROL TTS). The engine
should be run in for approx 30 minutes before you start flying and during the first 5 minutes do
not use full throttle. The engine will be fully run in once it's consumed 20 litres of fuel, the mix
then put bring the mix to 3%.
R-80/R-120: The life of an engine that has been correctly run in will be increased by 100%. A
badly run in engine has a high risk of being seriously damaged in its first hours of flight. The
best way to run in your new R 80 is to vary the load on it during the initial running minutes for
example:
Start & run engine for 2 Minutes; stop engine for 2 min. Start & run for 5 Minutes; stop engine
for 5 min. Start & run engine 10 min; stop engine for 5 min.
You should frequently change the throttle setting, gradually increasing & decreasing the revs
but avoiding full throttle. Never “blip” the throttle because you will place the centrifugal clutch
under abnormal loads. During this period of initial running we advise you to check the security
of all the mechanical parts as well as all the nuts, bolts and fittings before you start the engine.
You can fly your R 80 during the first 30 minutes of running in, but do not use full throttle more
than strictly necessary. If you are a heavy pilot we recommend you to run your engine on the
ground for at least an hour before flying it. After the first half an hour, check all the nuts, bolts
and fittings, especially those on the engine and the propeller. This check should ideally be made
every time you fly but at the very least be done every 5 hours.
It is possible that the engine may overheat during the running in period. If this happens you'll
notice a loss of thrust and you should switch the engine off and let it cool down, or at least,
immediately reduce the revs. An overheated engine can usually be detected by back firing
noises or by oil stains on the cylinder cooling fins. If the engine should overheat the bolts on
the cylinder head may become slack and should be checked – do not over tighten them! Don’t
mistake overheating for poor carburettor adjustment or dirt in the filter both of which may also
cause a loss of thrust.
Warning: Always wear appropriate clothing to operate your paramotor (Helmet, gloves,
proper shoes…).
Warning: Do not touch the engine, the exhaust system during and immediately after motor
operation. Risk of burning!
Warning: During operation beware of body or clothing contact with propeller or engine!!!
Warning: Comply with the safety advice of the paramotor manufacturer.
Warning: Inspect any part prone to wear before and after each flight in accordance with the
directive of the paramotor manufacturer.
Warning: Keep the running-in procedure as directed.

Warning: operate engine only in the specified limits.
Warning: Never engine with an empty fuel tank.
Note: Three flights of 5 to 10 minutes should be sufficient to warm up your engine when
new.
Note: To start with do not operate your engine for longer periods then stated above.
Note: You must run-in the engine before flying.
Note: Do not rev. up for five minutes while running-in.
Note: The running-in is over after consuming 10 litres of petrol.
Note: The lifespan of your engine can double with a proper running-in, while with a bad one
you may damage it since the very first hours of working.
Note: In the first phase of the running-in the engine must be switched on and off following
the cycles below:
engine 1° cycle 2° cycle next

Note: While on, the engine must be gently set at different revs, starting from the lowest up
to the highest.
Warning: Repeated revving are unsuitable, the clutch may be surcharged.
After each switching off, do carefully check all the mechanic parts, bolts and knots.
After at least 30 minutes of work you can fly avoiding high revs. for too a long time.
A heavy pilot requests more power to fly, in such a case is better to run the engine on the
ground for at least 1 hour.
After the first 30 minutes of run, do check all the bolts, knots and screws, particularly those of
the engine and the prop as well. Those of the engine (bolts and knots) must be checked every
5 hours of flight.
Engine overheating may occur while running-in; you can recognize it by a loss of power.
In this case is very dangerous to keep it on, it is better shutting off and let cooling, OR, AT
LEAST SLOW DOWN BELOW 5000 RPM before applying more power.A loss of power may occur
because a mixture too lean, following a wrong carburettor setting or dirty in the filter, do check
for such possibilities before restarting the engine
In case of overheating it is advisable to check the head screws to verify the seal of the motor
head, see locking torques. Usually a loss of seal can be perceived by dull strokes at starting or
by oil leakage, once the air conveyer is removed.

h. Maintenance
Warning: Change lock nuts for new ones if untightened!
MAINTENANCE - BEFORE EVERY FLIGHT IT IS IMPORTANT THAT YOU;
9Check that the propeller is not damaged, that it is secure and that it turns smoothly without
making noises. BE CAREFUL - never be tempted to put your hands in the paramotor once the
engine is started even though the propeller is not moving.
9Check that the exhaust pipe is correctly held in place and that it is not damaged; check that
all of the engine parts, air filter and carburettor, petrol tank and pipe, spark plug and starter
cable are fitted correctly and are secure. Check that nothing can come loose in flight because if
anything hits the propeller it will be a danger for the paramotor, the pilot and other people.
9Check the welding on the chassis, especially where the engine is located. Check that the
netting is securely held in place. Check that none of the paraglider lines are in the way of the
propeller and that nothing else can be sucked in.
Attention: If in doubt, do not take off!
When you have landed, use a clean cloth to remove traces of oil and dust from the engine and
the propeller. This is the best way to discover any potential problems.
MAINTENANCE - EVERY 5 HOURS
9Check the spark plug. The plug should be a mid-brown colour and the distance between the
electrodes should be 0.5 mm.
9Check all bolts. Take special care with the bolts on the cylinder head - they should be at a
torque setting of 9Nm (0.9 Kgm). To avoid damaging the cylinder head this check should be
made with the engine cold and the adjustment of the screws should be made in a diagonal
crossway fashion.
Clean the inline fuel filter.
9Check the bolts on the propeller. It is important that the propeller bolts are tight but equally
tight. Make sure that you do not crush the propeller by over tightening the bolts. 1.0 Kg/m is
the maximum recommended torque.
MAINTENACE - EVERY 20 HOURS
9Change the spark plug and check that the spark plug cable has not chafed.
9Check all bolts and lock nuts in general and in particular check the nuts on the base of the
exhaust pipe. Do not over tighten the exhaust manifold bolts.
9Check, whilst engine warm, the four bolts on top of the cylinder head. Pressure of tightness
should be 12 N.M (8.85 lbf.ft)
