ROUTINE OPERATING INSTRUCTIONS

g. Pull the starter rope (Figure 2-3) with a quick,

steady motion in a straight line through the guides. If a

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.

I. Adjust the applicable high or low pressure regulator

(see Figure 2-2) for the required delivery pressure as

indicated by the corresponding outlet pressure gage.

j. With the air hose and chuck assembly connected

to the appropriate outlet fitting, open the corresponding

high or low pressure shutoff valve (see Figure 2-2).
