NORMAL
PROCEDURES
When
using
an
external
power
source,
it
is
recommended
that the airplane
be
started with the alternator switches
OFF.
,--------NOTE-------......,
Release
starter
button
as
soon
as
engine
fires
or
engine
will
not accelerate
and
flooding
can
result.
The
continuous flow fuel
injection
system
will
start
spraying fuel in
the engine intake
ports
as
soon
as
the primer switch
;s
actuated
and
the
throttle
and
mixture control s are opened.
If
the auxil
iary
pump
is
turned
on
accidentally
while the engine
is
stopped with the
throttle
open
and
the
mixture
rich,
liquid
fuel
will
collect
temporarily
in
the
cylinder
intake
ports.
The
quantity
of
fuel
deposited
will
depend
upon
the
amount
of
throttl
e opening
and
the length
of
time the
pump
has
been
operating.
If
this
happens,
it
is
advisable
to wait a few minutes
until
the fuel
drains
away, then with the auxil iary fuel
pump
OFF,
magnetos
OFF,
mixture
IDLEI
CUT-OFF,
and
throttle
FULL
OPEN,
turn the propeller through
15
complete
revolutions.
This
is
done
to
prevent the
possibility
of
engine
damage
due
to
hydrostatic
lock before
starting
the
engine.
To
avoid
flooding,
begin
cranking the engine
prior
to
priming the
engine.
Engine
mi
s-starts,
characteri
zed
by
weak
intermittent
explosions
fol-
lowed
by
black
puffs
of
smoke
from
the
exhaust,
are the
result
of
flooding
or overpriming. This
situation
is
more
apt
to
develop in hot weather,
or
when
the
engines
are
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 weather 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 auxil iary fuel
pumps
should
be
switched
to
LOW
to provide
for
improved
purging
and
vapor
clearing
in
the
fuel system.
