Operation and Maintenance Manual, SEBU7252-03, "3500B High Displacement Generator Set Engines". Make a note about the information that follows in this Operation and Maintenance Manual. The correct information is in Operation and Maintenance Manual, SEBU7252-04, "3500B High Displacement Generator Set Engines". The correct information is in the Service Information System.Corrections to the Programmable System Parameters
The , "Ether Control" information that is on Page 31 is not correct. The correct information follows.Ether Control
Note: This is an optional feature.The ECM automatically injects ether into the air inlet manifold when the following conditions are met:
The engine rpm is greater than 75 rpm.
The temperature of the jacket water is below 31 °C (88 °F).The duration of ether injection varies linearly with the temperature of the jacket water. The duration of ether injection varies within the following range:
10 seconds at the maximum temperature of 30 °C (86 °F)
130 seconds at the minimum temperature of -40 °C (-40 °F)The longest duration of ether injection is 130 seconds even if the temperature of the jacket water is less than -40 °C (-40 °F). See Illustration 1.

Temperature of the jacket water and duration of ether injection (Y) Temperature in °C (X) Time in secondsA switch is installed on the control panel or the instrument panel. The switch enables the operator to inject ether manually under the following conditions:
The switch for ether injection is in the manual position.
The engine rpm is greater than 75 rpm.
The temperature of the jacket water is less than 31 °C (88 °F).Correction to the Maintenance Interval Schedule
The second Top End Overhaul that is identified on Page 92 is not correct. NO second Top End Overhaul should be scheduled. The Major Overhaul should occur between 18,000 and 22,000 Service Hours.Correction to the Maintenance Recommendations
Table 54 on Page 124 and Table 55 on Page 125 are not correct. NO second Top End Overhaul should be scheduled. The correct information is in the Table 1 and the Table 2 that follows:
