3.3.1 Oil Specifications
Use oil that meets the American Petroleum Institute
(API) classification of CD, CC/CD, or CC. Using
unsuitable oil or neglecting an oil change may result in
damage and a shorter engine life. Figure 3-1 shows the
recommended Society of Automotive Engineers (SAE)
viscosity designation for given operating temperature
ranges.

Note: Failure to observe these standards may cause
inadequate lubrication/oil pressure and
cold-starting difficulties.
3.3.2 Oil Check
Check the oil level in the crankcase daily or before each
startup to ensure that the level is in the safe range. To
check the oil level, remove the dipstick and wipe the end
clean, reinsert as far as possible into the tube and
remove. Maintain oil level between the Min and Max
marks on the dipstick. See Section 1, Service Views, for
dipstick location.

Figure 3-2 Oil Level Check
Note: Do not operate the set if the oil level is below the
Min mark or above the Max mark.
Note: Too high an oil level causes high oil consumption
and engine carbonizing. Too low a level
damages the engine.
Note: Do not check the oil level while operating the
generator set. Stop the generator set and keep
the generator set on a level surface while
checking the oil. Obtain the most accurate oil
reading by shutting down the generator and
waiting several minutes before checking the oil.
