ENGINE OIL
The tractor is shipped from the factory
with SAE-10W engine oil in the crankcase. If
the engine is to be operated at temperatures
between +75 degrees 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 oii from the crankcase
and replace it with new oil as specified in the
"Lubrication Table". The engine 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 engine.
To aid starting, the selection of crankcase
lubricating oils should be based on the lowest
anticipated temperature until the next drain
period.
Check the oil levels of the engine crank-
case and transmission to see that they are
filled to the correct levels. Note: Check the
oil level only while the engine is stopped.
