SAFETY INSTRUCTIONS WARNING! Ensure the engine is cool before operate this tester kit. WARNING! Never leave this tester kit attach to the crankshaft during operation. On some engines, the crankshaft will spin when air pressure form the tester is applied to the piston. To prevent the engine from spinning, shift the engine into high gear and apply the rear brake. A qualified technician is required to operate this tester kit. √ Wear complete eye protection and clothing protection. √ Never smoke or allow a spark or flame in vicinity of engine or battery. √ Keep this tester kit in the carry case and store in normal room temperature against rain, high humidity and high temperature condition. OPERATING 1. Check first the regulator knob is turned fully counterclockwise. 2. Clean the area around the spark plugs using compressed air, then remove all spark plugs. -1-
3. Remove the oil dipstick, radiator cap, and disconnect one end of the PVC hose. If the engine has a carburetor, remove the air cleaner and open the throttle all the way. If the engine is fuel injected, remove the air cleaner or open the throttle body. 4. Rotate the crankshaft until the piston the cylinder to be tested is at top dead center on the compression stroke. 5. Thread the correct adaptor hose into the spark plug hole. Do not connect the adaptor hose to this tester at this time. 6. Connect this tester to an air supply of up to 140 psi. 7. Set the gauge needle to 0% by adjusting the regulator knob. 8. Check the setting by momentarily connecting this tester to the adaptor hose. Needle will swing counterclockwise and then return to 0%. Repeat this step until the needle return to 0% without re-adjusting the regulator. 9. Connect this tester to the adaptor hose. The needle will swing counterclockwise and then clockwise as the cylinder is pressurized. 10. Read the percentage of leaking on the cylinder, when the needle stops. 11. Repeat the above steps to test on the other cylinders. 12. Refer to the following diagnostic techniques to determine the cause of the problem. Percentage of Cylinder Leaking 0% - 5% 6% - 14% 15% - 22% 23% - up
Engine Condition Engine is in excellent condition. Most engines built for racing have 5% or less. Engine is in good condition. Proceed with tune-up or adjustments. Engine is in poor condition. Engine can run but its performance is reducing. Engine is in very poor condition. Consider to re-build the engine.
Diagnosing an engine problem with this tool involves using a listening device (not included). A length of hose or A mechanic’s stethoscope is suggested. The lower the sound-pitch of escaping pressure the larger the leaking. Small leak will typically make a higher pitched sound. If the vehicle has multiple problems, the Cylinder Leaking Tester may show only the most pronounced problems. A larger problem may overwhelm a smaller problem during testing. When you find air escaping from the following parts, some components may have leaking problem. Parts Carburetor air horn Fuel injector body Exhaust system, tailpipe Crank case breather Radiator or fill cap Adjacent cylinders Oil dipstick tube
Components may have leaking problem Intake valve Intake valve Exhaust valve Piston/rings Head gasket or Cylinder wall cracks Head gasket Cylinder rings
