Fuel
CAUTION: Fill fuel tank at the end of each day of operation to drive out moisture-laden air
and to prevent condensation. Do not fill the tank to the brim. The fuel expands when it
gets warm and may overflow.
Water and sediment should be drained from the fuel tank at the start of each shift or after the fuel
tank has been filled and allowed to stand for 5 to 10 minutes.
Drain fuel tank of moisture and sediment as required by prevailing conditions.
After changing fuel filters, always bleed fuel system to remove air bubbles from system.
Air intake
Service air cleaners when RED band in indicator locks in visible position.

A-2A. LUBRICATION SPECIFICATIONS
Crankcase Lubricating Oils
Use oils which meet Engine Service Classification (MIL-L-2104D) or CD/TO-2. These are
additive-type oils that have been approved for use in Diesel Engines.
Consult the "EMA Lubricating Oils Data Book", Form SEBU5939, for a listing of CD oil brands.
The proper SAE grade of oil to select is determined by the ambient temperature at which the
engine is started and the maximum ambient temperature in which the engine will be
operating. To determine if the oil in the crankcase will flow in cold weather, remove the oil
dipstick before starting. If the oil will flow off, the oil is fluid enough to circulate properly.
Lubricating Grease
Use Multipurpose-type Grease (MPGM) which contains 3-5% molybdenum disulfide
conforming to MIL-M-7866, and a suitable corrosion inhibitor. NLGI No.2 Grade is suitable
for most temperatures. Use NLGI No. 0 or No. 1 Grade for extremely low temperatures.
