[1] CHECKING AND ADJUSTING

(1) Engine Body

Compression Pressure

1. Run the engine until it is warmed up.

2. Stop the engine and disconnect the 2P connector from the stop

solenoid in order not to inject fuel.

3. Remove the air cleaner, the muffler and all injection nozzles.

4. Set a compression tester (Code No. 07909-30208) with the

adaptor to the nozzle hole.

5. Keep the engine stop lever at “Stop Position”.

6. While cranking the engine with the starter, measure the

compression pressure.

7. Repeat steps 4 through 6 for each cylinder.

8. If the measurement is below the allowable limit, apply a small

amount of oil to the cylinder wall through the nozzle hole and

measure the compression pressure again.

9. If the compression pressure is still less than the allowable limit,

check the top clearance, valve and cylinder head.

10.If the compression pressure increases after applying oil, check

the cylinder wall and piston rings.

NOTEQ

• Check the compression pressure with the specified valve

clearance.

• Always use a fully charged battery for performing this test.

• Variances in cylinder compression values should be under

10 %.
