Maintenance
- Remove the plastic support and the gasket as
shown in the photograph
- Check that the SAS valve plastic support is not
dented or distorted
- Check that the gasket is in good conditions
- Carefully clean the inside and outside filters. Re-
place them if damaged or abnormally distorted.
- Make sure the coupling connecting the secon-
dary air to the head is not dented, overheated or
distorted. If there is, replace it.
- Check that the metal pipe does not have any
dents
To refit, follow the removal procedure but in re-
verse order, being careful to respect the direction
of the rubber coupling connecting the SAS valve
to the discharge system
CAUTION
INADEQUATE TIGHTNESS BETWEEN THE SAS VALVE
AND ITS SUPPORT INCREASES NOISE IN THE SAS SYS-
TEM.
CAUTION
WHEN TRAVELLING ON DUSTY ROADS, THE AIR FILTER
MUST BE CLEANED MORE OFTEN THAN SHOWN IN THE
SCHEDULED MAINTENANCE CHART.
CAUTION
NEVER RUN THE ENGINE WITHOUT THE SECONDARY
AIR FILTER
