with SAE-lOW
engine
oil in the crankcase.

at temperatures
between

F and 0 degrees
F. this
oil can be used for the first
five hours
of
operation.
If the temperatures
are not within
this
range,
drain
the oil from
the crankcase
and replace
it with new oil as specified
in the
"Lubrication
Table",

oil must be
drained
and replaced
with new oil every
30
hours
of engine
operation
thereafter.
Oils
designated
"For
Service
MS" are
recommended
for this

To aid starting,
the selection
of crankcase
