4.13 STARTING ENGINE
(a)
Starting Engine When Cold
Open the throttle lever approximately 1/4 inch. Turn “ON” the master switch and the
electric fuel pump.
Move the mixture control 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.
If the engine does not fire within five to ten seconds, disengage the starter, prime the engine
and repeat the starting procedure.
(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 optional feature called the Piper External Power (PEP) 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. Connect the RED lead
of the PEP kit jumper cable to the POSITIVE (+) terminal of an external 12-volt battery and the
BLACK lead to the NEGATIVE (-) terminal. Insert the plug of the 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.
NOTE
For all normal operations using the PEP jumper cables, the master
switch should be OFF, but it is possible to use the ship’s battery in
parallel by turning the master switch ON. This will give longer
cranking capabilities, but will not increase the amperage.
