DISMOUNTIN
G
The replacement of brake shoes must be
performed in complete set, never mount the
brake shoes equipped with brake linings of
different brands and qualities.
Dismou nt :
- the brake drum ( see the correspond-
ing paragraph); - the t wo maintenance springs ( R) of
the shoes with a brake cylinder rod ( T). By means of the pliers
FR05A the brake cyl-
inder pistons are immobilized.
Remove the return upper spring of the shoes
using the pliers FR03.
Release the end of the hand brake cable from
the hand brake lever.
Swing the adjustmen t lever (C) u p t o the mo-
ment it comes into contact with the rear wheel
steering knuckle. Distance the shoes from the plate.

Brake shoes
Checking of t he brake shoes wear may be pe rformed also without dismounting t he brake
drums.
In this purpose:-lift the vehicle by means of a two-column elevator;
- dismount the rubber protector of the visiting window from the brake plate;
- check by visual inspection the condition of the brake shoes wear.
If a serious wear is established, perform the brake shoes replacement (see the corresponding
paragraph).

Brake flexible hoses
IMPOSED PRECAUTIONS TO BE RESPECTED WHEN
DISMOUNTIN G – REMOUNTING A RECEIVER
OR A BRAKE FLEXIBLE HOSE
Due to security reasons, in order to avoid brake flexible hose twisting and the risk to get i n
contact with the suspension elements, it is necessary to observe the following operations sequence,
as well as the flexible attachment on the wing lining by means of a stopper, positioned at 135 ± 2
mm, value to be measured from the connection screw of the rigid pipe with the flexible hose.
DISMOUNTIN G
Dismount the connection ( 1) of the rigid pipe (6) from the flexible hose ( 2) till the moment
when the spring (3) is relaxed, having releasing the splinted area (4) of the sustaining support (5).

AIR REPARTITION CONTROL
The knob

(1).
Position
Ai rflow is di rected t owards the dashboard
side air vents.
Each air vent has three adjustments: - open or closed;
- upward or downward directed
- left or right directed
Position
Airflow is directed towards all dashboard air
vents and towards passengers legs.
Position
Airflow is directed towards passengers legs.
Op erating principle
Position
Airflow is distributed between all air vents,
defogging air vents of front side windows,
windscreen defogging air vent and passengers
legs.
Position
For a better e fficiency, the dashboard air
vents are t o be closed. The whole airflow is directed towards de-
fogging strip and air vents of the front side win-
dows.
Position
Entire cockpit is outside isolated and out-
side air penetration is not allowed, climate con-
trol blower operation being stopped.
AIR QUANTITY CONTROL
The airflow ra te cycled in the cockpit is
settled by the (C) knob position, corresponding
to the four speeds of the climate control blower.
The more speed step is bigger the more airflow
is bigger.
REMARK
For a better efficiency of the windscreen
defrosting or defogging, t he (C) knob m ust
be placed on the last position.
In order to stop the climate control blower
operation, rotate the knob on “ 0” position.

AIR CONDITIONING
62- 6
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.
