Q&A

CT fuel injector tester series Q&A

4. Common Questions and Answers

Q: Oil leakage from oil separator assembly.

A: When the oil separator leaks, check whether the installed O-ring is mismatched, deformed, or damaged. Replace it if mismatched or damaged. Do not over-tighten the two black adjusting screws, because this may cause oil leakage from the separator.

Q: Oil pressure drops slowly.

A: It is impossible for the oil pressure to drop to zero in 1-2 minutes. You can use a hexagonal spanner to adjust the relief valve counterclockwise.

Q: The buzzer beeps for a long time without oil pressure.

A: The machine has a lack-of-oil alarm function. When the fluid level is low, a beep sounds, and the pump and injectors shut off. Once enough fluid is added, the beep stops. In this case, press the [Run] key to restart the oil pump.

Q: The Drain Key must be pressed twice to completely drain the test solution.

A: The solenoid valve automatically shuts off after 15 seconds. If there is a large amount of liquid in the glass tube, you may need to drain it several times.

Q: Do I have to press by hand to adjust the value?

A: When the interval value is too high, press and hold to change the data continuously instead of pressing repeatedly.

Q: How much cleaning solution and test solution should be added?

A: When adding cleaning fluid, it should not exceed the injector nozzle connection. Test fluid should not exceed two-thirds of the glass tube screen.
