CRANKCASE OIL
Refer to engine nameplate or Periodic Maintenance
Schedule, located
in
the Operator's Manual, for oil
change interval. If operating in extremely dusty, high
ambient, or low ambient conditions change oil more
often.
Run engine until thoroughly warm before draining oil.
Stop the engine, place a pan under the drain outlet and
remove the oil drain plug or open the drain valve. After
the oil is completely drained, replace the drain plug or
close the drain valve. Refill with oil of the correct API
classification and appropriate SAE viscosity grade for
the temperature conditions.
Oil must meet or exceed the API designation SF, SF/CC
or SF/CD. Refer to the chart to determine the proper
viscosity grade of oil to use. Straight weight oils are
recommended for severe duty use and at temperatures
above
32"
F (0°C) for minimum oil consumption.
Crankcase pressure can blow out hot
oil and cause serious burns.
