200 MAINTENANCE AND LUBRICATION
ENGINE OIL LEVEL CHECK
As the operator of this vehicle, it is important for you to perform the daily inspections
necessary to keep your truck in good shape. Maintaining the proper oil level in your engine
crankcase cannot be overemphasized.
Before checking the oil, remember these important points:
•
Measurement of the oil level must be taken on level ground.
•
The best time to check oil level is while the engine is COLD (prior to starting at the
beginning of the work day, or after the vehicle has sat approximately 2 hours). At normal
operating temperature (engine oil temperature above 79.4°C [175°F]), oil level can be
checked 15 minutes after shut down.
CAUTION
Failure to wait a sufficient amount of time
(2 hours if engine oil temperature is below
79.4°C [175° F]) or 15 minutes if oil
temperature is above 79.4°C [175°F]) will
result in an inaccurate dipstick reading.
•
The level must be close to the FULL line (at least between the LOW and FULL lines) on
the dipstick, but must NOT exceed the FULL line (refer to illustration below).
