Measuring Procedure
1. Warm the engine up to normal operating temperature.
2. Remove the spark plugs.
3. Place the diagram sheet to compression pressure
tester.
4. Connect the adaptor to compression pressure tester
and install it into the spark plug hole.
5. Crank the engine approx. eight revolutions by using
the start motor.
6. Compare the measurements of compression
pressure tester with the specifications.
7. Measure the compression pressure of the other
cylinders in the same way.
8. If measured value is not within the specifications,
perform the cylinder pressure leakage test.
Notice
l
Discharge the combustion residues in the cylinders
before testing the compression pressure.
l
Apply the parking brake before cranking the
engine.
