4.7 STARTING ENGINE

(a) Starting Engine When Cold
Open the throttle lever approximately ¼ 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 ½ 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.
