Caution:
• In
order
to
keep the distance between the legs
of
the
relay
(RY901)
on the
AC
PW.B.
and
the
chassis, cut the
legs a bit
(1.5
mm) after replacing and soldering
the
relay.
• Pay
attention
to the following when replacing the
thermal fuse
(F903).
I)
Be
careful since the enclosed section may crack if the
force
is
applied
to
the base
of
the main body when
bending the lead wire
of
the thermal fuse.
2) Carry out soldering while radiating
heat
using a pair
of
radio pliers as shown
in
the figure below.
Attention:
•
Pour
conserver la distance entre les pieds du relais (RY
901),
de
la
plaquette acircuit imprime C.A.
et
Ie
chassis,
couper
legerement les
pieds(l,smm)apres
avoir remplace
les soudures de relais.
• Faire
attention
aux points suivants
quand
Ie
fusible
thermique
est
remplace
(F903).
1)
Toutes
les precautions necessaires doivent etre prises
pour
ne pas briser la section close
si
une force est ap-
pliquee
au
chassis de la partie principale quand
Ie
fi1
de
jonction
du fusible thermique
est
tordu.
2)
Effectuer
la soudure en
