Avoid parking the vehicle catalytic version
near dry brush wood or in places easily ac-
cessible to children, as the catalytic silencer
becomes extremely hot during use; be very careful
and avoid any kind of contact before it has com-
pletely cooled down.
The catalytic Amico 50 is fitted with a silencer with metal
catalytic converter of the "platinum-rhodium bivalent"
type. This device provides for the oxidation of the CO
(carbon monoxide) and of the HC (unburned hydrocar-
bons) contained in the exhaust gases, changing them
into carbon dioxide and steam, respectively.
Due to the catalytic reaction, the high temperature
reached by the exhaust gases makes for the burning of
the oil particles, thus keeping the silencer clean and
eliminating the exhaust fumes.

To have the catalytic converter function correctly and for
long and to reduce possible problems regarding the soil-
ing of the thermal unit and of the exhaust, it is necessary
to avoid covering long distances with the engine running
at constantly low rpm.
It is sufficient to alternate these periods with periods in
which the engine runs at relatively high rpm, even if only
for a few seconds, but rather frequently.
What has been stated above assumes particular impor-
tance for the cold starting of the engine: in this case, in
order to reach a rpm regime sufficient to enable the
"priming" of the catalytic reaction, just make sure that the
temperature of the thermal unit has reached at least
50°C, which generally occurs a few seconds after start-
ing the engine.
Do not use leaded petrol, since it causes the
destruction of the catalytic converter.

Exhaust gases contain carbon monoxide,
which is extremely noxious if inhaled.
Avoid starting the vehicle in closed or badly-
ventilated rooms.
The non-observance of this warning may cause loss
of consciousness or even lead to death by asphyxia.
Do not get on the vehicle for the starting.
Electric starting
Position the vehicle on the stand.
Lock at least one wheel, by pulling a brake lever (Fig.
7). If this operation is not carried out, the start relay re-
ceives no current and therefore the engine does not
start.
Turn the ignition switch (Fig. 8) to position "n".

Press the start push button
r
” (1-Fig. 9) without accel-
erating, then release it as soon as the engine starts.
Avoid pressing the start push button "
r"
(3) when the engine is running: this may
damage the starter.
When the start push button "
r" is pressed, the 2
stroke oil reserve warning light "
j" comes on.
With the engine in running condition, when the start
push button "
r" is released, the 2 stroke oil reserve
warning light "
j" must go out; if this does not oc-
cur, top up the 2 stroke oil tank
.
If the starting is carried out with cold engine, rotate the
cold start lever "
e" (1-Fig. 10) downwards.
Do not accelerate and pull the brake levers at the
same time until you move off.
Warm the engine up before leaving.
Once the engine has warmed up, rotate the cold start
lever "
e" (1-Fig. 10) upwards.

For the kick start, proceed as follows:
Position the vehicle on the centre stand.
Move to the left side of the vehicle.
To avoid losing control of the vehicle during the start-
ing, lock both wheels by putting on the brake levers
(Fig. 7).
Turn the ignition switch (Fig. 8) to position "n".
Do not push down the kick starter with the
engine on.
Push down the kick starter with your right foot, releas-
ing it immediately.
If necessary, repeat the operation until the engine
starts.
After a long period of inactivity, proceed as follows:
Move the ignition switch (Fig. 8) to position "n".
Make the starter run for about 10 seconds, in order to
ensure the filling up of the float chamber.
To start the engine:
Rotate the cold start lever "e" (1-Fig. 10) downwards.
Slightly open the throttle, then carry out the electric
starting procedure (or KICK START).
a
12
Release the throttle grip (Pos. A - Fig. 11), put on the
rear brake, then move the vehicle down the stand.
Get on the vehicle, keeping at least one foot on the
ground in order not to lose balance.
Properly adjust the inclination of the rear-
view mirrors.
To leave, release the brake lever and accelerate by gen-
tly rotating the throttle grip (Pos. B - Fig. 11); the vehicle
will start moving.
Avoid opening and closing the throttle grip
repeatedly and continuously, so that you do
not accidentally lose control of the vehicle.
If you have to brake, close the throttle and put on
both brakes in order to obtain uniform deceleration,
properly exerting pressure on the braking parts.
By putting on the front brake only or the rear brake
only, you reduce the braking force considerably,
thus running the risk of locking one wheel and con-
sequently losing grip.
Before beginning to turn, slow down or brake driv-
ing at moderate and constant speed or accelerating
slightly; avoid braking at the last moment: it would
be very easy to skid.
a
a
13
If the brakes are operated continuously on
downhill stretches, the friction surfaces can
overheat, thus reducing the braking efficien-
cy. Never drive with the engine off!
In case of wet ground or scarce wheel grip (snow,
ice, mud, etc.), drive slowly, avoiding sudden brak-
ings or manoeuvres that could make you lose grip
and fall down.
Pay the utmost attention to any obstacle or variation
of the ground.
Uneven roads, rails, manhole covers, indications
painted on the road surface, building site metal
plates become rather slippery by rain. For this rea-
son all these obstacles have to be carefully avoided,
driving smoothly and bending the vehicle as little as
possible.
Always use the turn indicators timely when you in-
tend to change lane or direction, avoiding sharp and
dangerous movements.
After the first 500 kilometres, carry out the
checking operations indicated in the column
"After running-in" of the PERIODIC MAINTE-
NANCE CHART, see p. 26, in order to avoid hurting
yourself or other people and/or damaging the vehi-
cle.
The running-in of the engine is primary to ensure its cor-
rect functioning and its correct functioning.
If possible, drive on hilly roads and/or roads with many
bends, so that the engine, the suspensions and the
brakes undergo a more effective running-in.
For the first 500 km, keep to the following indications:
0-300 km
Do not keep the throttle grip open more than one half for
long stretches.
300-500 km
Do not keep the throttle grip open more than three-
fourths for long stretches.
Remember: 1 mile = 1.6 km
1 km = 0.625 miles
a
a
c
14
Release the throttle grip and stop the vehicle by
putting on the brakes.
Move the ignition switch to position "m".
It is not necessary to close the fuel tap when
the engine is off, since it is equipped with an
automatic closing system.
Park the vehicle on firm and flat ground, to
prevent it from falling down.
Neither lean the vehicle against walls, nor
lay it on the ground.
Make sure that the vehicle and especially its red-hot
parts do not represent a danger for persons and
children.
Do not leave the vehicle unattended when the en-
gine is on or the key is inserted into the ignition
switch.
Do not sit on the vehicle when the stand is down.
Seize the vehicle using the rear grab rail and at the
same time push the stand lever downwards (see figure).
Make sure that the vehicle is resting firmly.

This vehicle is provided with front hydraulic disc brake.
When the disc pads wear out, the level of the fluid de-
creases to automatically compensate for their wear.
Periodically check the brake fluid level in the tank and
the wear of the pads, see p. 18 (CHECKING THE PAD
WEAR).
The brakes are the parts that most ensure
your safety and for this reason they must al-
ways be perfectly working.
ADJUSTING THE BRAKE
Measure the distance covered by the lever (9-Fig. 3)
before the brake starts it braking action.
The idle stroke at the end of the brake lever must be
about 5 ÷ 10 mm.
Adjust the clearance by acting on the adjuster
(1-Fig. 15).
Put on the brake (9-Fig. 3) repeatedly and make sure
that the wheel turns freely after the brake has been re-
leased.
Check the braking efficiency.
For any doubt regarding the perfect func-
tioning of the braking system and in case
you are not able to carry out the usual
checking operations, contact your
Official
Dealer.

Before carrying out the following opera-
tions, let the engine and the silencer cool
down until they reach room temperature, in
order to avoid burns.
Position the vehicle on the centre stand.
Unscrew and remove the two screws (1) and (2).
Slacken the two screws that hold the exhaust silencer
to the cylinder (access through the battery compart-
ment)
Remove the silencer (4).
Upon reassembly, change the exhaust man-
ifold-silencer seal.
Put on the rear brake (9 - Fig. 3) to lock the wheel.
Unscrew and remove the wheel nut (3) and the wash-
er.
Upon reassembly, change the wheel nut
(special type).

Check the wear of the rear brake shoes after the first
500 km and successively every 4000 km.
Remember: 1 mile = 1.6 km
1 km = 0.625 miles
To check the wear of the rear brake shoes, proceed as
follows:
Remove the rear wheel, see p. 17 (REMOVING THE
REAR WHEEL).
To check the thickness of the friction material, which
must never be less than 1 mm (Fig. 19).
If the minimum allowed limit has been
reached, if you notice any irregularity in the
operation or if any part is damaged, contact
your
Official Dealer, who will provide for
changing the brake shoes.
Check the brake pad wear after the first 500 km and suc-
cessively every 2000 km.
Remember: 1 mile = 1.6 km
1 km = 0.625 miles
The wear of the brake pads depends on the use, on the
kind of drive and on the road. The wear will be greater
when the vehicle is driven on dirty or wet roads.
To carry out a rapid checking of the wear of the front
pads, proceed as follows:
Position the vehicle on the centre stand.
Remove the brake caliper cover.
Carry out a visual checking of the friction material
thickness by looking between the brake caliper and
the pads.
If the thickness of the friction material (even of one pad
only) has reduced to about 1 mm, replace both pads.
Have the pads changed by your
Offi-
cial Dealer.

Grease the rear brake cam pin every 4000
km. If the vehicle is used on dusty roads,
this operation must be carried out more frequently.
Remember: 1 mile = 1.6 km
1 km = 0.625 miles
Disassemble the rear wheel, see p. 17 (REMOVING
THE REAR WHEEL (Fig. 18)).
Unscrew and remove the adjuster (1-Fig. 15).
Do not dirt the shoes and the friction materi-
al with grease, to avoid compromising the
braking efficiency of the vehicle.
This operation may be difficult because the
springs resist considerably to the removal
of the shoes. Be careful not to crush or
bruise your hands and fingers.
Grasp the inner edge of the two friction elements (1)
at its centre and, pulling toward yourself, shake the
two shoes, thus releasing them.
Loosen the nut (2) and remove the pin lever (3).
Withdraw the cam pin (4).
Moderately grease only the central part of
the pin.
Avoid dirting the cam or the areas around
the pin seat with grease.
Grease the central part of the pin by using grease for
kinematic motions, see p. 27 (LUBRICANT CHART).
Upon reassembly:
Neither strike, nor force the cam pin (4) with
hammers or others tools, in order not to
damage the two O-rings.
Manually insert the cam pin (4), rotating and pushing it
slightly.
Make sure that the springs are correctly
coupled.

Remember: 1 mile = 1.6 km
1 km = 0.625 miles
Check the conditions of the air cleaner and clean it
monthly or every 4000 km, depending on the conditions
in which the vehicle is used.
If the vehicle is used on dusty or wet roads, the cleaning
operations and any replacement should be carried out
more frequently.
Position the vehicle on the stand.
To remove the left side panel of the vehicle.
Unscrew the four screws.
Remove the filter case cover and extract the filtering
element.
To clean the filtering element use clean, non-inflam-
mable solvents or solvents with high volatility point,
then let it dry thoroughly.
Apply a filter oil or a thick oil (SAE 80W-90) on the
whole surface of the filtering element, then squeeze it
to eliminate the oil in excess.
The filter must be well impregnated, though
not dripping.
Periodically remove the spark plug and clean it carefully,
removing carbon deposits; change it if necessary.
To remove and clean the spark plug:
Remove the engine compartment cover.
Take off the spark plug cap.
Remove all the dirt from the base of the spark plug,
then unscrew it with the spanner you will find in the
tool kit and extract it from its seat, taking care that nei-
ther dust nor other substances enter the cylinder.
Make sure that there are neither carbon deposits, nor
corrosion marks on the electrode and on the central
porcelain part; if necessary, clean them with the spe-
cial cleaners for spark plugs, with an iron wire and/ or
a metal brush.
Energetically blow some air, in order to prevent the re-
moved residues from getting into the engine.
If the spark plug has crackings on the insulating mate-
rial, corroded electrodes or excessive deposits, it
must be changed.
