With the engine at idling speed :
- Unscrew the pressure-release screw on the pressure requlator by one or one and one half turns : a sound
, of leakage should be heard from the requlator.
= Retighten the release screw : cut-out must occur which results in a reduction in the running noise
emitted by the H P pump.
If not check in the following sequence
- that there is sufficient fluid in the reservoir,
- that the reservoir filter is clean and in good condition,
= that the H.P pump is primed and there is no air leak on the suction side of the pump,
- that the release screw of the pressure requlator is correctly tightened

ADJUSTING THE IDLING SPEED
To carry out this adjustment, the following is needed
A tachometer
A device lor checkinq idling speed adjustments on the carburettor ( or on approved gas analyser )
- A CDA 23 checking oppmotus or a workshop test bench ( equipment mentioned in the Equipment and Repair
Materials list, or in the Tools and Equipment notes green notes )
NOTE : WEBER Carburettors ref. No W 54-50, 55-50, 69-50, 74-50 fitted on 1977 models onwards ore fitted with a
fool-proof plug ( white ) on the mixture screw. To adjust the exhaust emission, this plug has to be
removed, and
replaced, after adjustment, with a a Repair PI plug ( black ). See Op. MA, 142-000 for removing and fitting the plug,
and the necessary tools.
ADJUSTMENT CONDITIONS
1.
The idling speed adjus!ment must be carried out on an engine on which the rocker clearances and the ignition
are correctly set. with a clean air filter and
with the engine in good order.
2. Check that the butterflies return fully to their stops.
3. 30 not let pnythinq except the ignition and the engine cooling fan ( or ions ) impose any load on the alternator.
4. Run the engine to bring the
oil temperature up to 70 to 80’ C ( wait for the electric cooling fan ( or fans 1 to cut

/,,,.I i,,jrr/io,, S~S,W1, ANNEXE : D - ADJUSTING THE IDLING SPEED AND THE EXHAUST EMISSION
CHECKING CONDITIONS
1.
Checking the idling speed must be carried out
on a clean engine on which the ignition and the
valve clearances are properly adjusted and
fitted with a clean air-filter.
2. Check that the throttle butterfly returns correctly
to its stop.
3. Do not load the alternator by switching an any
of the electrical components, except the iqnition
and the electric cooling fan (s) 4.
Run the engine to bring the oil temperature up
to 70 +o 80’ C ( wait for the electric cooling
fan is) to cut in ). IMPORTANT : Use exclusively (I high tension
tachometer ( do not damage the H.T. lead of
the ignition wiring harness ).
ADJUSTMENT
1. Check that the butterfly is not jammed in position
when it is resting against its stop.
2. Wait for the electric cooling fan (s) to cut in.
3. Use screw ( 1 ) to adjust the idling speed to 850
to 900 rpm.
4. Check the exhaust emission :
The resulting amount of CO - CO2 ( corrected CO
reading 1 must be beI& 4.5 %.
In case this reading cannot be obtained, check the
valve clearances, the ignition, the fuel pressure,
the air-tightness of the aircircuit, and the complete
fuel injection system.
5. On (I vehicle fitted with optional oirtonditioning
switch the compressor on, and adjust the idling
speed from 1000 to 1050
rpm, by adjusting the
screw on the auxiliary box located next to the
electro-vol”e.
