ATTENTION !
The tightness of the servobrake is checked on t he vehicle, with t he hydraulic cir-
cuit under operation Connect the vacuum meter between the servobrake and the inlet manifold by means of a “
T ” type connector. The connecting hose of the vacuum meter shall be as long as possible.
Start the engine and let it idle run for 1min.
Block the air suction hose by means of the MOT 453 device.
Stop the engine.
If air suction lowers with more than 33 mbar (25 mm Hg) in a 15 seconds period, it means
there is a loss at t he retainer valve (replace the valve) or at the servobrake membrane (replace
the servobrake). Dismount the MOT 453 device.
Dismount the vacuum hose.
Reinstate the connection between the servobrake and the inlet manifold by means of

AIR CONDITIONING

Operating principle
Air quantity adjustment in c ockpit
The flow of circulating air in cockpit is adjusted by rotating the (C) knob in the correspondin g
positions for the four speed steps of the blower. The more speed step is bigger the more airflow
is bigger.
For a be tter effi ciency of the windscreen defrosting or de fogging, t he (C ) knob m ust be
placed on the last position. In order to complete closing of the cold air penetration, rotate the knob on “ 0” position.
Air conditioning AC
When pushing the (D) button, the starting / stopping of the air conditioning is ensured. If ( D)
button is not pushed, the air conditioning is not working, ventilation being identical to the one of
a vehicle without air conditioning.
The use of air conditioning is enabling:-lowering the a ir temperature i n cockpit when the vehicle i s driven in sunny places or
when the vehicle is stopped in the sunshine; -reducing the humidity in cockpit (event facilitated by defogging).
Air conditioning can not be used at low outside temperatures. During air conditioning operatio n,
for a better efficiency, all windows must be closed.
R ecycled air
When pushing the ( E) button, the climate maintenance unit is working with cockpit recycled
air, without outside air penetration.
Air recycli ng is enabling:
- isolation from outside atmosphere;
-f aster reaching the desired temperature in cockpit.
Prolonged use of this function may lead to glasses fogging. Normal operation returning, with
outside air, is t hen imposed, by pushing the (E) button stopping the cockpit air recycling.

Pressure controller
LOCATION
Pressure controller (1) is located on the high-
pressure pipe, near the dryer reservoir.
FUNCTION
The pre ssure control ler is perm anently
informing UCE (electronic control unit) about
the circuit pressure. Subject to pressure value in the high-
pressure circuit, UCE is commanding:
- circuit break ( by uncoupling the compressor
clutch) when the pre ssure in the c ircuit is
decreasing under 1,96 + /-0,2 bar a nd clutch
coupling when the pressure is over 2,16 +/-
0,2 bar;
- circuit break when the pressure in the circuit
is over 31,4 +/- 2 bar and compressor clutch
coupling when the pressure is decreasing under
25,5 +/- 2 bar;
- engine fan starting on second speed, when
the pressure is over 17,7 +/- 1 bar and engine
fan stopping when the pressure is decreasing
under 13.7 +/- 1 bar.
REPLAC EMEN T
The pressure controller replacement does
not imply the draining of the refrigerant circuit. Disc
onnect the pressure controller
connector.
Replace the pressure controller.
When m ounting, lubricate the pressure
controller sealing gasket with oil PAG SP 10.
T ighten the pressure controller to the required
moment of 0,9 +/- 0,1 daNm.
Check for refrigerant fluid leaks.

ATTENTION !
In case of acid splashes on body, abundantly wash with water all affected parts.
If eyes have been touched, urgently call for a doctor.
1. DANGER = EXPLOSION RISK
During battery charging, connected to a charger-rectifier, oxygen and hydrogen emissions are
occurring. These gases emission is stronger when the battery has reached the complete charge
condition and the produced gas quantity is in direct connection with the charging current.
The oxygen and hydrogen are associating in the free spaces, at the plates surface, forming a
detonate mixture, which is very explosive. The littlest spark is sufficient to generate an explosion,
followed by the battery case brooking and a cid splashing in the proximate environment. The
persons, who are a round, are in da nger t o be hurt by t he e xploded case chips or by the acid,
which may come i n contact with the eyes, hands, or face.
ATTENTION !
Strictly observe the following recommendations:
- before connecting or reconnecting a battery, ensure that all consumers are shouted off.
- during battery charging in a room, using a charger-rectifier, turn it off before connecting or
reconnecting the battery to this one;
- do not place metallic objects on t he ba ttery for not producing a short-c ircuit between i ts
pl ugs ;
- never bring closer to a battery, a n open flame, a welding lamp or another fire source.
THE ELECTRIC EQUIPMENT PROTECTION
In case of an intervention on the vehicle, some measures must be taken, for the electric equip-
ment protection against damages or for avoiding a short-circuit that may lead to vehicle firing.
The battery is to be allwith disconnected by first disconnecting the negative plug and then t he
positive one. Connection is to be done by performing the disconnecting operations in the reverse
order.
Before starter acting, check if the battery is correctly connected (the negative plug connected
to the mass), and if the plugs are clean and well tightened. Never disconnect the battery when the
engine is running, in order not to damage the voltage regulator, the alternator or some components
of the vehicle checking electronic systems. The alternator, voltage regulator disconnecting, and
the interventions at their connections, are to be performed only when the engine is stopped (the
alternator is not turning) and the contact is taken off. In case the battery is connected to a charger-rectifier, for charging (without dismounting the
battery off the vehicle), it is obligatory to disconnect the wiring from the battery plugs.
