HOW TO USE:

1. Prepare the Engine: Ensure the engine is at normal operating temperature. Turn off the engine and allow it to cool slightly to a safe handling temperature. Disconnect the glow plug harness or fuel injectors, depending on the engine design and specific test procedure.
2. Remove Glow Plugs/Injectors: Carefully remove all glow plugs or fuel injectors from the cylinders you intend to test.
3. Connect the Tester: Select the appropriate adapter and thread it into the glow plug or injector port. Connect the quick coupler of the tester’s hose to the adapter.
4. Perform the Test: Open the throttle fully. Disable the fuel system and ignition system if applicable. Crank the engine for at least 4–7 compression strokes or until the gauge reading stabilizes.
5. Record Readings: Note the compression reading and release pressure using the deflator button before testing the next cylinder.
6. Repeat and Compare: Test all cylinders and compare readings. Differences over 10–15% may indicate issues.
