rising sufficiently
in
bread
slot when
bread
is
removed. This
in
turn would keep
the other end
(E)
(Diagram
I)
from moving out far enough
to
allow Trigger
(C)
to
drop into position shown. The friction might
be due to
Trip Lever
(E)
rubbing
guide
wires,
as
there
is
not
sufficient end play
at
the bearing points for free
action;
or
the
ends
of
the
Trip
Lever
entering
the
bearings
might
not
be
straight,
thus causing binding.
If
Trip Lever appears
to be
free of
excessive
friction,
then
it
is
likely that clearance indicated by dimension
(D)
(Diagram
I)
is
insufficient.
To
check this clearance
it
will be
necessary
to
remove End
Shell from Toaster. Make sure Thermostat
is in
"off" position, and Contacts
(H)
are
open,
then with the Trip Lever up
(no
bread
in
Toaster)
this clearance,
as
indicated by dimension
(D)
,
should be approximately
1/16".
Adjust by bending
Trip
Lever.
If
this
dimension
is
too
small,
then
as
Toaster heats
up,
it
is
likely that Trigger
(C)
will not fall
down,
when toasted slice
is
removed,
to
properly position
it
for next cycle.
If,
on the other hand,
this dimension
is
too great,
there
is
a
possibility that
the
Thermostat Blade
(A)
will not be
pushed forward sufficiently when next
slice
is
inserted,
causing
the
results
indicated
in
paragraph, Section
D-3
(c)
If
the Bread
Lifter Assembly
(17)
cannot be pushed down by
hand,
it is
possible
that the end of the Trip Lever
(E)
Diagram
I,
got caught over the top of the
Trigger
(C)
.
This
might
happen
in
shipping
if
the
stops
on
the
Side
Frame
Assemblies
(14
and
16)
are
bent
out
of
position,
allowing
the
Bread Lifter
Assembly
to pass
the
stops.
Bend stop lugs
in
correct position
so that
Bread
Lifter Assembly
(17)
cannot pass by when forced
to one side or the other.
(d)
The Reset
Pin
(G)
might have come out
of
the hole
in
the Thermostat Bracket
(F)
preventing
the
Contacts
(H)
from closing. This can be caused by the Trigger Arm
(K)
being bent
out of
shape permitting the Pin
(G)
to
pass by the Trigger Arm
(K),
or
the
Contact
Spring
(H)
might
be
improperly
assembled
causing
misalignment.
Correct
by bending
Trigger
Arm
(K)
in
correct
position
or
by
adjusting Contact Spring
(H)
.
After this adjustment, care must be taken
to
make
sure there
is
a
clearance
of
a
few
thousands
(not
over
1/64")
between
the Pin
and Trigger Arm when
the
Thermostat Blade
is in
the "off" position. To make sure
Thermostat
is
in
the
"off"
position,
push
the
Reset
Arm
(Diagram
II)
inward
below
the pivot.
(e)
Any
electrical
interruption
will
prevent
the
Bread
Lifter
Assembly
from
lowering. Check all connections and cord.
3.
Bread Moves
Up and Down
Continuously
at Top of Slot
-
Dimension
(D)
(Diagram
I),
as
explained
above,
is
too
large.
When this
occurs,
Thermostatic Blade
(A)
cannot
be
moved forward sufficiently
to snap
it to
its
toasting position. However,
the
movement
is
usually sufficient
to
close Contacts
(H)
.
When this happens,
the Bread Lifter
Assembly
will begin
to
move
down, but
as
soon as
it
moves about
1/2 inch,
the
Contact
Points
(H)
will open causing Bread Lifter Assembly to rise. This, in turn, will cause
Contact
(H)
to
again close and thus repeat above cycle. Adjust
