  • RUGGED DESIGN FEATURES RUBBER BUMPERS TO PROTECT THE GAUGES
  • EXCLUSIVE LONGACRE GAUGE MANIFOLD METERS THE AIRFLOW FOR PRECISE READINGS
  • INSTRUCTIONS:
    1. WARM THE MOTOR UP TO NORMAL OPERATING TEMPERATURE.
    2. REMOVE ALL SPARK PLUGS. PUT TRANSMISSION IN NEUTRAL. BLOCK WHEELS.
    3. REMOVE THE ROCKER ARMS OF THE CYLINDER TO BE CHECKED.
    IMPORTANT NOTE:
    TURN THE CRANKSHAFT SO THAT THE PISTON IS AT BOTTOM DEAD CENTER. IF YOU DO NOT, THE MOTOR WILL SUDDENLY TURN OVER WHEN YOU CONNECT THE AIR, POSSIBLY CAUSING SERIOUS INJURY TO YOU OR SOMEONE ELSE WORKING ON THE MOTOR.
    4. SCREW THE HOSE INTO THE SPARK PLUG HOLE OF THE CYLINDER TO BE TESTED. BE SURE THAT IT IS TIGHT ENOUGH TO COMPLETELY SEAL. LEAKAGE HERE WILL GIVE YOU A FALSE READING - LOWER THAN TRUE LEAKDOWN.
    5. CONNECT THE HOSE TO THE TESTER AND TO YOUR AIR SUPPLY. IDEALLY IT SHOULD BE BETWEEN 110 AND 125 PSI (175 PSI MAX) AND BE CLEAN AND MOISTURE FREE.
    6. ADJUST THE REGULATOR UNTIL THE LEFT GAUGE READS 100 PSI. (SEE NOTE A BELOW IF YOU AIR SUPPLY CANNOT MAINTAIN 100 PSI ON THE LEFT GAUGE.)
    7. AT THIS POINT THE RIGHT GAUGE WILL DISPLAY THE LEAKDOWN AS A %. FOR EXAMPLE 92 PSI ON THE RIGHT = 92% LEAKDOWN OR 8% LEAKAGE (100 - 92 = 8). YOU CAN SEE THE CHART THAT WILL BE SUPPLIED FOR LEAKAGE %. IF YOU GET AN EXTREMELY LOW LEAKDOWN % AND THE MOTOR SEEMS TO BE RUNNING WELL CHECK FOR A BLOCKAGE IN THE PRECISION RESTRICTION BETWEEN THE GAUGES.
    8. IT IS BEST TO LOWER THE REGULATOR SETTING BEFORE DISCONNECTING EITHER AIR LINE TO AVOID RAPID PRESSURE CHANGES TO THE GAUGES.
