Note
- Cleanliness is extremely important when
working on the injection equipment.
- Only use pure test oil according to ISO
4113 or clean diesel fuel to test the
injection valves.
Caution!
After about three or four actuations of the
hand lever, the spring space above the
nozzle needle in the injection valve fills up
with diesel fuel/test oil. Then it is no longer
possible to actuate the hand lever.
The nozzle lock nut must be loosened
carefully before every test procedure to
release pressure from the spring space.
