4. Check oil level -- oil level must be above the red
line on the sight gauge or to full mark on dipstick.
New unit is supplied with break in oil in the crank-
case.
5. Open the valve in the discharge line between the
compressor and air receiver, where used.
6. Make sure proper pressure relief valve is between
the compressor and any line shutoff valve, check
valve or aftercooler.
7. Open the valve in the air line to unloading control,
where used.
8. Check V--belt drive for alignment and proper ten-
sion.
9. Check compressor sheave for proper rotation.
Break- - in oil is supplied in the crank-
case from the factory. Change oil and
oil filter after 50 hours and refill the
crankcase with lubricating oil. See
FIGURE 1, below, for viscosity re-
quirements.
INITIAL STARTING -- When starting for the first time,
be certain that all items in the prestart have been com-
plied with.
Warm Weather Operation: 32_ F to 90_ F Ambient
Warm Weather Operation: Above 90_ F Ambient

FIGURE 1 - - VISCOSITY REQUIREMENTS FOR VARIOUS TEMPERATURE RANGES
On initial start or after the compressor has been over-
hauled, run the compressor with the receiver outlet
valves wide open for about ten minutes so that oil will
be distributed over all wearing surfaces. When sure
that the unit is operating satisfactorily, partly close the
receiver valve and gradually bring the pressure up to
normal working pressure.
To ensure proper ring seating on a new or overhauled
unit, run fully loaded for the first 40 hours.
COLD WEATHER STARTING -- In addition to the nor-
mal starting procedure, make sure the weight of the oil
in the crankcase is suitable for existing temperatures.
Refer to "Lubrication" section, below. Start the unit un-
der no load and stop before gaining full speed. Repeat
this operation until pressure registers on the oil gauge
or until oil has a chance to reach all moving parts.
After the unit is started, proceed as under normal start-
ing.
LUBRICATION -- Oil level in the crankcase must be
maintained. Add oil as required to maintain the correct
level. The viscosity required for various operating tem-
perature ranges is listed in FIGURE 1, below.
The correct weight of oil for existing temperatures is
most important. Oil which is too heavy cannot splash
freely and will cause bearing damage and subsequent
failure. Approximately 9 quarts of oil are required to fill
the crankcase.
The oil level must be checked and maintained on a daily
basis.
