FAQs
What types of engines is this kit compatible with?
This kit is specifically designed for petrol (gasoline) engines. It is not compatible with diesel engines.
How do I get accurate readings?
Ensure the engine is warm, the accelerator pedal is fully depressed, and you crank the engine for 4-5 compression strokes for each cylinder. Compare readings between cylinders, looking for significant differences.
What does a low compression reading indicate?
A low compression reading in one or more cylinders typically indicates wear or damage to piston rings, valves, or the cylinder head gasket.
How do I reset the gauge?
There is a built-in reset button on the gauge. Press this button after recording the reading for a cylinder to clear the measurement before testing the next one.
What is the measuring range of the gauge?
The gauge has a measuring range of 0 to 20 Bar, which is equivalent to 0 to 300 Psi.
Can this kit be used for diesel engines?
No, this kit is exclusively for petrol engines and cannot be used for diesel engine diagnostics.
Troubleshooting
Gauge not reading any pressure
Ensure the adapter is securely tightened in the spark plug hole. Check that the hose connection to the adapter is airtight. Verify the engine is being cranked correctly.
Inconsistent readings between cylinders
Ensure consistent cranking speed and number of strokes for each test. Check for air leaks around the adapter connection. Clean any debris from the spark plug hole.
Adapter does not fit spark plug hole
Verify you are using the correct adapter for your specific spark plug type. Consult the kit's manual or manufacturer specifications if unsure.
Gauge needle is stuck
Press the reset button firmly. If the needle remains stuck, there may be an internal issue with the gauge; consider replacing the gauge if possible or the entire kit.

Setup, Compatibility & Care
Setup:
- Ensure the engine is at normal operating temperature.
- Remove the spark plug from the cylinder to be tested.
- Select the appropriate glow plug adapter or fixed connection and screw it into the spark plug hole.
- Connect the hose from the gauge to the adapter.
- Press the accelerator pedal fully and crank the engine for 4-5 compression strokes until the gauge reading stabilizes.
- Record the reading and press the reset button.
- Repeat for all cylinders, comparing the readings.
Compatibility:
- This kit is specifically designed for petrol engines.
- It is not suitable for diesel engines due to different compression ratios and injector types.
Care:
- After use, disconnect all components and clean them with a dry cloth.
- Store the kit in its original case in a cool, dry place to prevent damage and loss of parts.
- Inspect the rubber seals and hose regularly for wear or cracks.
