●
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
●
Make sure that no foreign mate-
rial enters the crankcase.
6. Start the engine, and then let it idlefor several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
7. Turn the engine off, and then check the oil level and correct it if
necessary.

not dripping.
6. Insert the mesh and the spongematerial into the air filter case.
NOTICE: Make sure that the
mesh and the sponge material
are properly seated in the air fil-
ter case. The engine should
never be operated without the
mesh and the sponge material
installed, otherwise the pis-
ton(s) and/or cylinder(s) may
become excessively worn.
