second pull is necessary, set the choke lever at the original
position. When the engine starts, slowly return the choke
lever to the fully open position. After engine warm-up,
adjust the throttle to the fully open position.
h. As the compressor package assembly operates,
check the receiver pressure gage (see Figure 2-2) at
regular intervals to make certain air pressure in the
receiver is increasing at a steady rate. Allow the unit to
operate until the receiver pressure is adequate to supply
the charging requirements.

to the appropriate outlet fitting, open the corresponding
high or low pressure shutoff valve (see Figure 2-2).
