1. Choose the adapters according to the fuel top-supply injector from the coupler box and mount a proper O-ring on it. Remember to apply a little lubricating fuel on the O-ring.

2. The adapters for fuel top-supply injectors are 4 types:
   Thread sealing type: here are with coarse thread and fine thread.
   O-ring sealing type: here are with big holes and small holes.

3. If the injectors cannot be fixed because of the hole being bigger than the injector, need to sue the auxiliary support.

4. Need to adjust the relative position between the Knurled nut and adjustable screw so that the injectors can be fixed well on the unit.

Installation of side-supply injectors

1. Choose proper couplers for side-supply injectors and proper O-rings, and mount them together.
2. Before fixing, best to apply a little lubricating fuel on the O-ring.
3. If some cylinder is not used, need to install the plug.

Operating Procedures

Preparation

1. Remove the injector from the motorcycle engine to check the o-rings inside for damage. If it is be damaged need to replace it. Put the outside of the injector in gasoline or detergent, and wipe it with a soft cloth after cleaning the outside fuel sludge carefully.
2. Check the test liquid level to be sure there is enough test liquid inside the tank. Pour test liquid from the port at the top left side of the unit and watch the liquid level in the fuel level viewer. In most cases, the liquid up to 1/2 of the tank capacity.
3. Turn on the power switch on the right of the Cabinet.
4. Pour ultrasonic detergent into the ultrasonic cleaning basin so that the needle valve of the injector is covered by the detergent.
5. Connect the injectors with the right couplers.

The main unit of the device uses a test solution for uniformity/spray ability test, leakage test, injecting flow test and auto. test. The ultrasonic cleaner uses the cleaning agent. Test solution and cleaning agent are not included in the standard configuration and can be purchased separately.

2. It is strictly prohibited to immerse the pulse signal line connector along with the injector into the ultrasonic pool for cleaning. Otherwise, the pulse signal line connector can be damaged easily.

Uniformity/Sprayability Test
The uniformity test is to find out the difference of the injectors injecting at the same working condition. This test can indicate the comprehensive influences on the injector caused by electrical nature, bore variation and clogging. The spray ability test is to inspect the spraying performance by observing the injectors.
Installing and testing procedures for injectors

1. Choose a proper adaptor according to the injector type and mount it to the fuel separator.
2. Install the injectors in the forward direction (Apply a little lubricating grease on the O-ring.)
3. Install the fuel separator with the injector onto the plate of the test tube.
4. Connect the injector pulse signal wire.
5. Before doing this test, press the DRAIN icon to drain the test liquid from the measuring cup if there is any.
6. Select the Uniformity/Sprayability test function, set corresponding parameters (consult the appendix for pressure setting, consult vehicle manuals for other parameters as needed), and then press the RUN key to start the test.
7. When the test is completed, the equipment will auto-stop with the ring of the buzzer.

Note

1. While testing, it can drain fuel by pressing the DRAIN icon. At default, the solenoid valve is set at the closed state. Uniformity test can be done at this state. When the DRAIN icon is pressed, the solenoid valve will drain fuel.
2. The system pressure can be adjusted by pressing + or – at testing.
3. During operation, the user can select parameters, such as RPM or PW, and then press key to achieve the status of the simulation.
4. Good injectors may have identical injecting angles, and uniform spraying but no jet. Otherwise, replace the injector.
5. In the spray ability test, a special electrical parameter–the minimum injection pulse width of the injector–can be tested, to compare the injectors on the same engine. That is to set cylinder No., start the test from minimum injection pulse width, and then gradually increase the pulse width till the injector starts injection (observed with the help of backlight). The value set at this moment is the minimum injection pulse width, so the difference of minimum injection pulse width among these injectors could be observed.

Backflushing
Backflushing is limited to the top-supply injector by connecting the backflushing connector under a uniformity/playability test. Test solution enters from the outlet of the injector and flows out from the inlet during backflushing. Backflushing can wash away the dirt inside the injector and dirt attached to the filter.

1. Find the backflushing connector (and select a supporting “O” ring to install it on the connector) installed below the fuel separator;
2. Install the top-supply injector in the reverse direction (outlet up, inlet down);
3. Select the corresponding coupling element under the injector according to the shape of the injector;
4. Adjust the screws to fix the fuel separator and injector assembly in the fuel filler hole of the upper cover according to the height of the injector and tighten the compression screws (black) on both sides evenly;
5. It is recommended to press the [Drain] button to drain the remaining fuel in the transparent tube to avoid overflow of the test solution before backflushing.
6. Connect the pulse signal line of the injector properly; set the operating parameters and press the Run button to execute the backflushing function; the system pressure can be adjusted by + and – buttons on the control panel during backflushing.
7. The system will stop automatically after the completion of the cleaning.
