Preparations for operation after
long-term storage
1. Remove all adhesive sealing tapes from
the openings of the engine.
2. Drain the rust preventing oil and anti-rust
agent by using the following procedure,
and replace it with the specified amount
of engine oil, fuel and cooling water.
Lubricating system:
Drain oil through the drain plug of oil pan
and oil filter.
Fuel system:
First operate the engine with the mixed
fuel that is used in the rust preventing
operation, and then drain the fuel.
Cooling system:
If antifreeze is used, drain cooling water
from the drain valves on each of the radi-
ator and cylinder block, and flush the
cooling system.
If an anti-rust agent is used, flush the cool-
ing system.
Exterior of engine:
Clean the exterior surfaces of the engine
with a petroleum solvent (Trichlene).
3. Replace the elements of the oil filter, the
air cleaner and the fuel filter with new
ones.
4. Adjust the fan and governor belt for
proper tension.
5. Check and adjust valve clearance. Apply
engine oil to the rocker arm and other
valve mechanism.
6. Check the battery electrolyte level and
specific gravity. Refill and/or recharge if
it is necessary.
7. Before the engine starts, disconnect the
high tension cables from the spark plugs.
8. Set the ignition switch at the “START”
position, and crank the engine for about
10 seconds. Repeat this cranking opera-
tion two or three times in order to dis-
perse engine oil to every portion of the
engine, and then install the high tension
cable.
9. Start the engine, and let it idle for about
5 minutes.
10. Gradually increase the engine speed to
the rated rpm, and run the engine for
about 10 minutes under no load. Make
sure that the charge warning lamp and
oil warning lamp are off and cooling
water temperature are normal, and that
the engine does not produced any abnor-
mal vibration or noise.
