The start aid as-sembly mounted on the center support, is usedasan aid in starting the engine at temperatures below40° F. This system is controlled by the ENGINEPRIMER switch on the control cubicle panel whenthe engine is being cranked aml the START-RUN-STOP switch is in the START position. Each timethe ENGINE PRIMER switch is momentarily actu-ated, under these conditions, one metered shot ofether is injected into the engine air intake system.This section also contains information for main-tenance of the electric fuel transfer pumps whichare utilized to transfer fuel from the main fueltank to the daytank.3 - 1 6 2 .
