(OPTIONAL)
WARNING:
Avoid
making
sparks
and
keep
all
burning
cigarettes
or
fire
away
from
the
vicinity
of the
airplane.
Make
sure
the
oxygen
shut-off
valve
on
the console
is in
the
closed
position. Inspect
the
filler
connection
for
cleanliness before
attaching
St
to
the
filler
valve. Make
sure
that
your
hands,
tools,
and
clothing
are
clean,
particularly
of
grease
or
oil,
for
these contaminants
will
ignite
upon
contact
with
pure
oxygen
under
pressure.
As
a
further
precaution
against
fire,
open
and
close
all
oxygen
valves
slowly during
filling.
When
recharging
the
oxygen
system
remove
the
protective
cap
from
the
filler valve and
attach
the
hose
from
an
oxygen
recharging
cart to
the
filler
valve.
(On
TO-1
thru
TC-954
the
oxygen
cylinder
is located
behind
the
cabin
aft
bulkhead.
On
TC-955
and
After;
and
TE-1
and
After;
TH-1
and
After,
the
cylinder
and
filler valve
are
located
in
the
forward
utility
compartment
of the
nose
section).
To
prevent
overheating,
fill
the
oxygen
system
slowly
by adjusting
the
recharging
rate
with the
pressure
regulating
valve
on
the
cart.
The
oxygen
cylinder
should be filled
to
a
pressure
of
1850
50
psi
at
a
temperature
of
70"F. This
pressure
may
be
increased
an
additional
3.5
psi
for
each
degree
of increase
in
temperature;
similarly,
for
each
degree
of
drop
in
temperature,
reduce the
pressure
for
the
cylinder
by
3.5
psi.
When
it
becomes
necessary
to
I
disconnect
a
fitting
refer
to
the
table
of thread
lubricants,
Table
1,
for
correct
thread lubricant
before
connecting
the
fitting
back
into
the
system.
MA
GNETOS
Ordinarily,
the
magnetos
will
require
only
occasional
adjustment,
lubrication and breaker
point
replacement.
CA
UTION:
The
internal
automatic
grounding
devices used
on
the
original
S
series
magnetos
have
proved
unreliable
in
service
and
current
production
magnetos
do
not
have this
feature. To
be
safe,
treat
all
S
series,
S200
series,
and
51200
series
magnetos
as
hot
whenever
the
ground
lead is
disconnected.
To
ground
the
magneto,
connect
a
wire
to
the switch
lead at
the
filter
capacitor
and
ground
the
wire
to
the
engine
case.
If
grounding
is
impractical,
remove
the
cable
outlet
plate
on
the
rear
of
the
magneto
or
disconnect all the
spark
plug
leads.
DELCOTRON
ALTERNA TOR
The
Delcotron alternator
and
regulator
are
designed
for
use
on
only
one
polarity
system,
therefore,
the
following
precautions
must
be
observed
when
working
on
the
charging
circuit. Failure to observe
these
precautions
will result
in
serious
damage
to
the
electrical
equipment.
a.
When
installing
a
battery,
always
make
absolutely
sure
the
ground
polarity
of
the
battery
and the
ground polarity
I
of the
DELCOTRON
are
the
same.
b.
When
connecting
a
booster
battery,
make
certain
to connect
the
negative
battery
terminals
together
and
the
positive battery
terminals
together.
c.
When
connecting
a
charger
to
the
battery,
connect
the
charger
positive
lead
to
the
battery
positive
terminal and
the
charger
negative
lead
to
the
battery
negative
terminal.
d.
Never
operate
the
DELCOTRON
on
open
circuit.
Make
absolutely
certain
all
connections in
the circuit
are
secure.
I
e.
Do
not
short
across
or
ground
any
of
the terminals
on
the
DELCOTRON
or
regulator.
f.
Do
not
attempt
to
polarize
the
DELCOTRON.
For
additional
overhaul,
testing,
brush
replacement
and
lubrication,
refer to
Delco-Remy
Service
Bulletins
16-262
and lR-273.
