NORMAL PROCEDURES

Verify that the carburetor heat for each engine is off and the cowl flaps are
open.
Verify that both stabilator and rudder trim is set to neutral and that the fuel
selectors are on.
All other electrical switches and radio master switch should be off to
avoid an electrical overload when the starter is engaged. Check that all circuit
breakers are in.

When starting at ambient temperatures +20°F
and below, operate first engine started with
alternator ON (at max charging rate not to

before initiating start on second engine.
4.13a Normal Start - Cold Engine (4.5c)
Turn the battery master switch ON and check that the three green gear
position lights are illuminated. Open the throttles about 1/4 inch. Advance the

one engine at a time using the following procedure.
Turn the electric fuel pump on. Prime the engine as required. Verify the
propeller area is clear, then turn on the magneto switches. Engage the starter.
When the engine starts, adjust the throttle and monitor the oil pressure. If
no oil pressure is indicated within 30 seconds, shut down the engine and have
it checked. In cold weather it may take somewhat longer for an oil pressure
indication.
Repeat the above procedure for the opposite engine. After the engines
have started, check the alternators for sufficient output and the gyro vacuum
gauge for a reading between 4.8 and 5.2 in. Hg. and that the flow buttons are
