FAQs
What is the purpose of the pressure relief valve?
The pressure relief valve is a safety feature that releases pressure when the testing is complete, preventing damage to the gauge and allowing for safe disconnection.
Can I use this kit on diesel engines?
Yes, this kit is designed for both petrol and diesel engines.
What should I do if the gauge needle doesn't move?
Make sure the adaptor is securely connected and that there are no leaks. Check for any obstructions in the hose or the gauge.
How do I interpret the compression readings?
Compare the readings to the manufacturer's specifications. Low readings in one or more cylinders indicate a problem that needs further investigation. Significant differences between cylinders suggest mechanical issues.
How often should I calibrate the gauge?
The gauge should be calibrated annually or if you suspect it is providing inaccurate readings. Contact a professional to calibrate the gauge.
What should I do if the hose kinks?
If the hose kinks, it may affect the accuracy of the reading. Replace the hose if it is damaged. The included anti-kink coils help prevent this.
What do I do if the adaptor doesn't fit?
Make sure you are using the correct adaptor for your vehicle. If the correct adaptor is not included, you may need to purchase an additional one.
How should I store the kit?
Store the kit in the provided plastic storage case in a dry place to protect the components and keep them organized.
Troubleshooting
Gauge reading is zero.
Ensure the adaptor is properly sealed in the spark plug or glow plug hole. Check the hose connections for leaks. Verify that the pressure relief valve is closed.
Inaccurate readings.
Make sure the engine is at operating temperature. Fully charge the battery to ensure proper cranking speed. Ensure the throttle is fully open during the test. Check for any leaks in the system.
Adaptor doesn't fit the engine.
Double-check the adaptor selection guide. If a suitable adaptor is not included, an alternative adaptor may be required.
