NOTE
The fuel injector valve should only be disassembled if the inspection (07.08.01.nn.)
yields deficiencies (e.g. leaking, too low opening pressure, poor atomization).
All parts of the injection system are produced with utmost precision in special work-
shops. This is the only guarantee for a proper function. For this reason, it is impossi-
ble for the operator to repair it and the necessary maintenance work should be
limited to
•
cleaning
•
inspection of opening pressure and tightness
•
replacement of wearing parts making use of original parts and replacement ele-
ments.
In order to keep repair costs low, elements in need of repair should be got ready for
shipment as complete units and clearly marked to prevent them from being mixed up.
