1.When it is switched on,the unit doesn't correspond.
When you meet this trouble,you need to check the fuse at lower right side of the unit to see if it is damaged or broken,then replace it.
2.If there is leakage in the fuel distributor coupler,you need to check the o-rings and if it is damaged or unfitted,you should replace it.Please remember,do not tighten the two riffle screws too tightly or it may cause leakage.
3.If the fuel pressure drops slowly,then the fuel pressure can't drop to zero within 1~2 minutes,you can turn the overflow valve slightly with the inner hexagonal spanner counterclockwise.
4.When there is no fuel pressure,the buzzer still rings continually.
In general condition,because of its "fuel-lack warning" function,the buzzer will ring when the liquid in the fuel tank is lack,and then it will switch off the fuel pump and injectors and returns to the stop state automatically,and you just need to supply the cleanser or test liquid to stop the ring.But when there is no fuel pressure,the buzzer still rings,you need to press the "RUN" key to rerun the fuel pump and injectors.
5.The malfunction code displays E001.
The malfunction code of E001 is displayed only when the level inside fuel tank is lower than that of the required level and the buzzer will ring to remind user to full the fuel.Once the condition appears during the running process,the Launch CNC-602A Injector Cleaner Tester will stop the fuel pump after 10 seconds and you should make "RUN" indicator on the flashing state.If there is too much liquid,you should press the "Drain" key to drain the liquid into the fuel tank to resume the liquid level;If the liquid is not enough,you should supply the liquid and after the liquid is up to the required specification,the buzzer will stop ringing.And if you press the "RUN" key,the Launch CNC-602A Injector Cleaner Tester would continue to run the interrupted work.
