SAE O1W-30 or 10W-40 may be used as an acceptable
alternate under all temperature conditions.
SAE 10W-30 or l0W-40 must be used during operation in
extreme heat, dusty, or sandy areas.
Engine oil must conform to Specification MIL-L2104 and be
marked "For API Service CC," or "For API Service CD."
NOTE
Pour slowly, crankcase capacity is about 1 qt. (1.0 liter).
h. Fill the engine Fuel Tank (1, Fig. 1-3) with clean, fresh diesel fuel, type #2, or 2D. Do not mix oil with diesel
fuel. Do not use gasoline, fuel additives or other starting fluids in fuel tank. Do not overfill or spill. If fuel is spilled, wipe up
immediately.
WARNING
Diesel fuel is highly flammable. Do not store or use diesel fuel near
open flame or extreme heat emitting devices such as heaters,
welders, torches, lanterns, etc. Use diesel fuel only in a well
ventilated area. Do not fill tank with engine running.
i.
Check that a clean filter element is installed in the compressor air intake filter (12, Fig. 1-3). Check that the
prefilter and inlet hose (11, Fig. 1-3) is properly installed.
j.
Check that all drain valves (16 & 17, Fig. 1-3) operate freely and that all safety valves are installed and are
secure.
Section II
COMPRESSOR LOCATION
2-2.
GENERAL. To avoid contaminants that are sometimes found in free air, it is essential that the air compressor
intake is not exposed to the contaminating effects of internal combustion engine exhaust, ship engine or ventilator
exhaust, unventilated rooms or ships compartments, areas of high dust levels, or areas where excessive moisture is
present. It is also not advisable to fill SCUBA tanks when an air pollution alert is in effect. The method of avoiding
contamination is given below.
2-3.
OUTDOOR LOCATION.
a.
Position compressor unit so that exhaust fumes from the engine are blown away from the unit.
b. Connect black plastic hose of pre-filter (supplied with each compressor unit) to the compressor air intake filter
(11, Figure 1-3). Locate pre-filter as shown in Figure 2-1
