Before starting any work
Carry out the work in the following order:
A Cleaning
B Checking
If a check shows that one or more injectors still do not work satisfactorily, repeat the cleaning process and then check them again.
If, in spite of this, an injector still shows too great a difference in performance as compared to the others, it should be changed.
Note: To be sure of a change in flow capacity, it is recommended that checking be carried out before cleaning is started.
