NORMAL PROCEDURES
(b) Starting Engine When Hot
Open the throttle approximately 1/2 inch. Turn ON the master
switch and the electric fuel pump. Move the mixture control lever
to full RICH and engage the starter by rotating the magneto switch
clockwise. When the engine fires, release the magneto switch and
move the throttle to the desired setting.
(c) Starting Engine When Flooded
The throttle lever should be full OPEN. Turn ON the master
switch and turn OFF the electric fuel pump. Move the mixture
control lever to idle cut-off and engage the starter by rotating the
magneto switch clockwise. When the engine fires, release the
magneto switch, advance the mixture and retard the throttle.
(d) Starting Engine With External Power Source
An External Power receptacle allows the operator to use an
external battery to crank the engine without having to gain access
to the airplane's battery.
Turn the master switch OFF and turn all electrical equipment
OFF. Insert the plug of a 28 volt DC aux power jumper cable
into the socket located on the fuselage. Note that when the plug is
inserted, the electrical system is ON. Proceed with the normal
starting technique.
After the engine has started reduce power to the lowest
possible RPM, to reduce sparking, and disconnect the jumper
cable from the aircraft. Turn the master switch ON and check the
alternator ammeter for an indication of output. DO NOT
ATTEMPT FLIGHT IF THERE IS NO INDICATION OF
ALTERNATOR OUTPUT.
