9-piece compression tester kit for petrol engines

• Package Contents: The motorcycle compression tester includes 1 x spring-lock gauge; 4 brass adapters (M10, M12, M14, M18); 1 x metal extension rod connector; 1 x straight aluminum metal rod and 1 x curved rod for direct testing; and a rubber extension hose for long-range testing. The complete fuel pressure tester kit offers great convenience. You do not need to purchase these parts separately.
• Dual-Scale Dial Gauge: Dual-division gauge, measuring range of 0 to 20 bar (0 to 300 psi), acrylic glass gauge cover with rubber protection to prevent scratches and provide excellent shock absorption.
• Thank you. Thanks to the built-in check valve with pressure-holding function, you can obtain accurate readings from our engine compression gauge.
• Function: The compression tester kit was developed to detect a variety of common engine faults, such as a blown valve, carbon deposits, a cracked cylinder head or faulty main gasket, a defective or worn piston ring set, or a burned or damaged piston. The unique safety valve design withstands pressure and ensures fuel safety.
• Application: This motorcycle compression tester comes with various sizes of turn and socket adapters and is widely used in most types of gasoline engine cylinders and deep spark plugs, often found in motorcycles, lawnmowers, cars, trucks, ATVs, etc. Note: This compression gauge is not suitable for diesel engines.
• Easy Storage: All parts are organized in a plastic case to protect the components and are easy to carry and store. The integrated motorcycle compression tester kit allows you to test many engine systems.

With detailed instruction manual

How to use:

1. Start the engine and allow it to return to normal operating temperature. Once the engine has stopped, discharge all spark plugs;

2. Fully adjust the throttle. and press the pressure gauge fitting onto the cold end of the spark plug;

3. Run the engine for 3 to 5 seconds at a speed of 100 to 150 rpm. During this time, the instrument needle will gradually rise but will stop at a certain value. At this point, the reading is the cylinder compression pressure.

4. Press the button to zero the pointer.

5. Following the steps above, repeat the measurement 2 to 3 times to improve accuracy.

Note:

1. Please ensure all parts are properly installed before proceeding with the bottle pressure test.

2. When the ignition is on, do not touch any part of the test equipment; turn off the engine and remove the key each time before touching it.
