Make sure there is adequate ventilation. Fluid vapour may be released from hot fixtures
or high pressure leaks and a mist may develop from the spray chamber. The specific

pressure pump is active, refer to Figure 4.22
When the test has finished, press the Stop

4.5.1
Removing the Injector from the Spray Chamber
1. Disconnect the high pressure pipe, the electrical connector and the back leak hose from the
injector under test.
2. Loosen the Injector Clamp.
3. Remove the injector from the spray chamber assembly by gently twisting the injector
upwards until the nozzle is clear of the O-ring (Figure 4.27). Avoid pulling the injector
upwards as this may cause fuel to exit the spray chamber.

4. If removed, make sure to refit the O-ring into the top of the spray chamber ready for the next
injector test.
