The resultant churning can cause extra loss, hightemperatures, and oxidized oil. If, during operation, the oil level goes above the maximum shownon the sight gauge, drain enough oil to bring the level back within the recommended operatingrange. Do not permit the operating level to fall below the minimum shown on the gauge.ATTENTION!Should it ever become necessary to add excessive amount of make-up oil, investigateimmediately for oil leaks.Change the oil at regular intervals. The time between oil changes depends upon the severity ofoperating conditions and, hence, must be determined by the motor user. Two or three changes ayear is typical, but special conditions, such as high ambient temperature, may require morefrequent changes. Avoid operating the motor with oxidized oil.Use only good grade, oxidation-corrosion-inhibited turbine oils produced by reputable oilcompanies.22
