hot.
If it occurs, repeat the starting procedure with the
throttle approximately 1/2 open, the mixture in IDLE CUT-OFF
and the primer switch OFF.
As the engine fires, move the
mixture control to FULL RICH and close the throttle to idle.
If an engine is underprimed, as may occur in cold wea-
ther with a cold engine, repeat the starting procedure while
holding the primer switch on for 5 to 10 seconds until the
engine fires.
If cranking longer than 30 seconds is required, allow
starter-motor to cool five minutes before cranking again,
since excessive heat may damage the armature windings.
After the engines are started, the auxiliary fuel pumps
should be switched to LOW to provide for improved purging and
vapor clearing in the fuel system.
TAXIING
A steerable nosewheel, interconnected with the rudder
system, provides positive control up to

left or right,
and free turning from 18° to 55° for sharp turns during
taxiing.
Normal steering may be aided through use of dif-
ferential power and differential braking on the main wheels.
These aids are listed in the preferred order of use.
NOTE
If the aircraft is parked with the nosewheel
castered in either direction, initial taxi-
ing should be done with caution.
To straight-
en the nosewheel, use full opposite rudder
and differential power instead of differen-
tial braking.
After a few feet of forward
travel, the nosewheel will steer
norm~lly.
At some time early in the taxi run, the brakes should be
tested, and any unusual reaction, such as uneven braking,
should be noted.
If brake operation is not satisfactory, the
aircraft should be returned to the tie-down location and the
malfunction corrected.
The operation of the turn-and-bank
indicator and directional gyro should also be checked during
taxiing.
