OPERATOR MAINTENANCE INSTRUCTIONS
Section I. LUBRICATION INSTRUCTIONS
TOOLS AND EQUIPMENT (Not Applicable to Air Force.) The tools required to perform operator and unit
maintenance on the generator set are listed in Appendix B of this manual.
3-2 GENERAL LUBRICATION INFORMATION.
This paragraph contains lubrication instructions which are supplemental to, and not specifically covered
in the Lubrication Order.
b. Refer to Lubrication Order LO 9-6115-464-12 for lubrication instructions.
The dipstick is marked to indicate that the crankcase oil level may be
checked and oil added while the engine is running or stopped. Always make
sure the correct side of the dipstick is checked. When checking oil with en-
gine running, remove oil filler cap. Equipment damage could result if cau-
tion is not observed.
c. When changing the engine crankcase oil, never fill the crankcase above the FULL mark on the dipstick.
Do not allow the oil level to fall below the ADD mark on the dipstick. Service the oil filter element each
time that the crankcase oil is changed.
d. A seal in the dipstick cap prevents oil from leaking from the crankcase and foreign material from entering.
Keep the dipstick firmly seated on the adapter tube at all times.
Keep the crankcase breather tube open at all times to prevent pressure build-up in the engine crankcase
which will cause oil leakage from the crankshaft seals.
