Routine maintenance checks and workshop troubleshooting
Key specifications
Tool type: manual compression tester with analogue pressure gauge
Application: petrol (spark-ignition) engines
Measurement: cylinder compression pressure readings
Port/connectors: fittings suitable for spark plug openings (kit includes necessary adaptors)
Construction: hand-held gauge and hose assembly for direct engine connection
Portability: compact kit for bench or mobile use
How to use
Before testing, ensure the engine is at operating temperature and the ignition system is disabled to prevent starting. Remove the spark plug from the cylinder to be tested and install the appropriate adaptor from the kit into the spark plug hole. Attach the hose and manual gauge, then crank the engine for several compression strokes while observing the gauge. Record the peak pressure and compare readings across cylinders to identify anomalies. Follow engine manufacturer guidelines for cranking duration and safety precautions.
