Clean the heat exchanger (radiator)
The surfaces of the heat exchanger (radiator) come into contact with
external air and may be subjected to deposits and impurities. Clean
them as needed with compressed air or vapours.
Injector calibration
The injectors require periodic cleaning and calibration of the exact
injection pressure, by adding or replacing the shim washers inserted
under the spring; check the injection pressure by using a hand
operated pump equipped with a pressure gauge which, operated by
the lever, enables the injector calibration pressure to be obtained and
which is displayed on the pump pressure gauge at the moment in
which diesel delivery occurs. During the test it is also possible to note
whether the direction of the jet is correct and whether the injectors
show any signs of fuel leakage. Clean the injectors using a metal brush
to remove the carbon deposits from the nozzle tips.
When using compressed air, it is required to use
suitable personal protections for hands, face and eyes.
The requirements can be found in the ACCIDENT
PREVENTION chapter.
