(3) Change lubrication engine oil
Oil should be changed once after the first 20/40 hours of operation and then once every 250
hours of operation thereafter. The generator set is equipped with an hourmeter which records
actual engine operating time. The ideal time to change oil is soon after a power delivery run
when the engine is at operating temperature.
NOTE: If lubricating oil is drained immediately after the unit has been run for some time, most of the
sediment will be in suspension and oil will drain readily without clinging to internal surfaces.
CAUTION
NOTE: Change the oil filter each time the oil is changed (250 hours).
(4) Change oil as follows:
a. Provide a container for catching used oil. Capacity should be greater than 2 gallons.
b. Remove drain plug located in oil pan. Allow sufficient time for oil to drain from valve train,
timing gear case, etc., before reinstalling plug.
NOTE: Change oil filter while oil is draining.
Change oil filter as follows:
c. Place a container under the oil filter to catch oil drippings.
d. Loosen filter with a special oil filter removal wrench. Several types are available. Discard oil
filter.
e. Coat the gasket on the new filter with oil.
f. Place the new filter in position on the cylinder block and spin on until the gasket contacts the
adapter face; then hand tighten another 1/2 turn. Do not over-tighten.
g. Clean drain plug and reinstall. DO NOT over-tighten.
