For now,
we
willput two
turnsof initiol
tension
on
the moin-
spring. lf everything
is
working
properly,
two turns of tension
should be
sufiicient
to
cock
ond
releose
ihe shutter. But
the
initiol
tension
moy require
further odiustment
to bring
in the
shutter
speeds.
Cocking
the
shutfer odds
initiol
tension
to the moinspring.
So we wont
to cock
the
shutter twice without
releosing
it
--
the
moinspring
then retoins
the initiol
tension.
First,
cock the
shutter by
turning
the
sprocket in the
film-
odvonce direction.
Then,
turn the moin drive
column
slightly in
o clockwise direction
(os
seen
from
the top of the mechonism)
until it
is lotched by
the releosed-position
lotch. Although
the
moin
drive
column is now
in its
releosed
position, the
lower end
of
the tronsfer
shoft
still
blocks
the
wind com --
preventing you
from cocking
the shutter
ogoin. So
iustdepress
the
releose
plunger
--
thot moves
the tronsfer
shoft
below
the lug
on the
wind com.
Now,
cock the
shufter o second
time
by
turning the
sprockei.
You
hove
iust
opplied
two full turns
of initiol
tension to
the
moinspring.
Once
ogoin, turn
the moin
drive
column
clockwise
until
it is
hela by
the
releosed-position
lotch ond depress
the
releose
plunger. You
con nowcock
ond releose
theshutter in
the
normol monner.
Test
the shutter
operotion
ot
oll of the
shutter speeds. Then,
set the speed knob
to'ibulb"
--
cock ond releose
the shutter, but
hold the
releose
plungerdepressed.
While ihe moin drive
column
is
held
by
ihe bulb
lever,
check
the relotionship between
the
bulb
lug
(on
the moin drive
column)
ond the lotching
end of
the
bulb
lever --
the bulb
lever
should be
centered
on the bulb
