Low compression readings may indicate worn piston rings, damaged valves, or a blown head gasket.
No, this kit is specifically designed for petrol engines.
Test compression if you suspect engine problems like misfires, poor fuel economy, or difficult starting.
The color-coded scales help you quickly assess if the compression is within normal, low, or critical ranges.
Compare the readings of each cylinder. Significant differences between cylinders indicate a problem. Consult a repair manual for specific engine compression specifications.
Store the kit in a clean, dry place to protect the components from damage and corrosion.
If the gauge doesn't move, recheck all connections and ensure the engine is cranking properly. Also, consider the possibility of internal engine damage.
Ensure the adaptor is securely screwed into the spark plug hole. Check for leaks in the hose or around the adaptor.
Re-test each cylinder. Ensure the engine is at the correct operating temperature and that the throttle is fully open during the test.
Compatibility: This kit is designed for most modern petrol engines.
Care: Clean the kit after use. Store it in a dry place. Inspect the hose and adaptors for any damage before each use. Avoid over-tightening the fittings.
