## Long description

Handheld engine compression tester Forsage F-908G1 is a diagnostic tool designed for measuring cylinder compression in petrol engines. The kit includes an eight-piece adapter set that fits common spark plug and injector ports with thread sizes from M10 to M18 and provides pressure readings across a range of 0–21 bar. It is intended for pinpointing compression-related faults such as leaks, worn piston rings, valve seating problems or head gasket failures and for supporting routine maintenance and repair workflows.
Advantages
The tester offers a compact, manual design that allows quick connection to individual cylinders and direct pressure readings up to 21 bar. The included adapters cover a broad range of thread sizes from M10 to M18, reducing the need for additional fittings. Durable construction and a straightforward interface make the tool suitable for use in workshop and field environments where portable, reliable compression measurement is required.
Suitable for
 Diagnostic compression checks on petrol engines
 Detecting cylinder leakage, valve and piston wear
 Verifying repair work after gasket or valve service
 Routine engine maintenance and fault-finding
Key specifications
 Measurement range: 0–21 bar
 Adapter set: 8 pieces covering thread sizes M10, M12, M14, M16, M18 (and intermediate sizes included in the set)
 Connection type: threaded adapter connection for spark plug or injector ports
 Operation: handheld, mechanical/analog pressure gauge
 Intended engine type: petrol (gasoline) engines
How to use
Warm the engine to operating temperature, then switch off ignition and remove all spark plugs. Attach the appropriate adapter for the cylinder to be tested and connect the tester to the spark plug or injector port. Crank the engine several revolutions while observing the pressure gauge to obtain a stable peak reading. Record readings for each cylinder and compare them to manufacturer specifications or relative values across cylinders to identify anomalies. Follow standard safety procedures to prevent accidental starts and to relieve pressure before disconnecting.
Usage recommendations
Use consistent cranking conditions and ensure the engine is at normal operating temperature for comparable results; if readings are low, perform a wet test by adding a small amount of oil to the cylinder to help distinguish ring wear from valve or head gasket issues.
