JIFETOR Compression Tester Kit, Small Engine Features

• CYLINDER COMPRESSION TEST AND DIAGNOSTIC: JIFETOR automotive engine compression tester kit is used for measuring pressure on gasoline engine cylinder quickly and accurately. The gauge readings assist to diagnose if there are following problems: valve sticking, carbon build-up, cracked cylinder head or defective main gasket, poorly seated or worn piston rings, burned or damaged piston. Please refer to the vehicle manufacturer's service instructions or proprietary manual and our manual for detail

• WIDE USE OF SMALL ENGINE COMPRESSION TESTER: There are 16" long flexible extension hose with 4 sizes (10mm 12mm 14mm 18mm) selectable brass adapters in the engine compression test kit, widely suitable for most types and depth spark plug well on gasoline petrol gas fuel engine cylinder, which is common in motorcycle, car, ATV, snowmobile, dirtbike, lawn mower, chainsaw etc. Please note, the engine compression gauge is not used for most diesel engine, due to the low pressure range 0-300PSI

• UNIVERSAL AUTO CYLINDER PRESSURE TEST GAUGE CONNECTORS: The straight and angled push-on connectors in the cylinder compression tool kit are equipped with rubber tapered tip for easy and quick installation, you just need to push and hold it seal against cylinder head, rather than screw to tighten like 10mm 12mm 14mm 18mm appropriative adapters.

Assist to diagnose following problems: Valve sticking Carbon build-up Cracked cylinder head or defective main gasket Poorly seated or worn piston rings Burned or damaged piston A variation in compression readings between cylinders is often a better indication of engine problems than the absolute values of compression NOTE 1. Please wear gloves and goggles when use 2. These auto cylinder compression test tool should be used by professional or under the guidance of a professional 3. Always refer to the vehicle manufacturer's service instructions, or a proprietary manual, to establish the current procedure and data 4.
