The
initiol testof
the
speed com
position
is
similorto thot we
described
for the
Argus C-3.
You
should
hove no retord
on the
fostest speed
(l/300
second),
ond
iust
o whisper of retord
on the
next-to-the-highest
speed
(lrl100
second). But
for criticol
oc-
curqcy,
you con odiust
the
speed com
occording
to the
procedures we'll describe
in
your next lesson.
The
Argus C-4
speed com
hos on in-ond-out
odiustment.
So
for less reiord
(ond
thereby
o foster
speed),
we
move
the entire
speed
com in
--
toword
the escopement.
And for more
retord
(ond
thereby o
slower speed), we
move the
speed com toword
fhe
speed knob.
To reoch
the speed
com odiustment
point,
first toke off the
speed knob by
removing its
center
screw
--
there's
o compression
spring
under
ihe speed knob. Now,
locote
the bross.speed
control
d'isc
with its
locking
spline
screw, Fi9. 53. By
loosening the
locking
screw, you con
rotote the speed
control disc
ond thereby
chonge the
omount of reiord
for the
speeds of
