NOTE : The camber angle is not adjustable.
1. Prepare vehicle and set in position f src chapfrrs
I and 2 ).
2. Setting up checking apparatus :
Place the apparatus on the magnetic support of the
wheel to be checked.
Use the axis corresponding to the blue mmu A..
Keep the level in a horizontal position. Tighten
locking screw ( 1).
3. Checking the comber angle :
IMPORTANT : Check that the reading Ll has not
changed ( SC<’ rhnprcr I ).
a) Turn the disc (2 ) until the fixed spirit-level
bubble (3 1 is centred.
b) Note in blur scnle (at o a n ) the reading of the
comber rmqle.
c ) Carry out the same operation on the other
wheel.
Comber angle must be between 0’ + 13’ - 29’
IV. CHECKING AND ADJUSTING THE,CASTOR ANGLE
IMPORTANT : For precise results from this check
it is imperative to set the vehicle heights as follows :
165 mm a+ front and 215 mm at rear f Salooss) or
228 mm ( Esfafes ).
1. Setting the vehicle height :
a) Check measurements Ll and L2 f see chapter I ).
b ) Release pressure in suspension system.
2. Setting control opportus :
3. Checking castor angle :
Place the apparatus on the magnetic bracket of
the wheel to be checked using the axis corres-
ponding to grren (ITTOII’ H.
a) Turn wheels 20’ outwards : to the left for the
left-hand wheel and to the right for the right-
hand wheel.
Keeping the apparatus horizontal tighten locking
screw ( 1).
b) Turn the disc ( 4) until the zaro mark is opposite

Flap V 1 is controlled by C 1. It is controlled pneumatically by vacuurr
The vacuum intake is at the carburettor
The flap is controlled by a pneumatic piston subjected to vacrrum via a switch When control C 1 is positioned
between the small blue square and the red square the piston,in the switch is lifted ( fiq ( A ) ) vacuum intake
is cut off’ the supply pipe to the pneumatic piston is at atmospheric pressure flap V 1 blanks off intake E 2, and
air drawn into the intake on the bonnet comes from outside With the engine runninc and control C 1 positioned
between both blue squares ( fiq. ( B ) ) the piston in the switch comes down under the action of its spring.
supply
pipe to the pneumatic piston is no lonqer under atmospheric pressure but under the action of the vacuum, and
flap V 1 via the pneumatic piston blanks off intake E 1’ the air drawn in comes from the passenqer compartment,
( recycling position ).
NOTE Identification mark for fittinq the one way valve the outer diameter is reduced on the side of the 3-way union V. FAST IDLING SPEED CONTROL
This control allows for a faster idling speed when the compressor is operatinq
A vacuum capsule incorporated in the carburettor slightly opens the first choke butterfly by means of a small rod.
The amount of opening is adjustable by means of a screw on top of the vacuum capsule.
An electromvalve fitted to the R.H side of the front subframe and supplied at the same time as the electro-maqnetic
clutch for the compressor controls the supply of vacuum to the capsule. t FRONT
