Danger!

Danger of injury when handling the nozzle

tester.

The fuel penetrates deep into the flesh

through the nozzle jet!

Caution, blood poisoning!

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 cap nut must be loosened care-

fully before every test procedure to release

pressure from the spring space.

Only use pure test oil according to ISO

4113 or clean diesel fuel to test the fuel

injectors.
