5.2 COMPRESSION PRESSURE
1. Run the engine until warm.
2. Stop the engine and remove the air cleaner, the
muffler and all nozzle holders.
3. Set a compression tester to the adaptor installed in
the nozzle holder hole and fixed with the locating
screw.
4. Pull the stop lever to cut the fuel and run the engine
with the starter at 200 to 300 rpm for 5 to 10 seconds.
Measure the maximum pressure while running, sev-
eral times
• For the test, use a fully charged battery and the
specified valve clearance.
• If the pressure does not reach the allowable limit,
apply a small amount of oil to the cylinder wall
through the nozzle holder hole and measure the
pressure again.

• If the pressure raises after applying oil, check the
cylinder wall and piston rings.
• If the pressure still low, check the top clearance,
valve clearance and cylinder head.
• If the compression differs more than 10% among
the cylinders, trace the cause of pressure variation
and take corrective measures.

NOTE:
• Check the compression pressure with the specified
valve clearance for proper air intake.
5. MEASUREMENT AND ADJUSTMENT
5.1 FAN BELT
1. Measure the deflection, depressing the belt half-
way between the fan drive pulley and the alternator
pulley at 78.5 N (8 kgf, 17.6 lbs) of force.
2. If the deflection is not between the factory
specifications, loosen the bolts and nuts, and relo-
cate the alternator to adjust.
3. Replace the belt if damaged or worn
