Operating
Instructions for X35
and
X45 Devices
a. Turning on
Master
Switch HS
Motor M starts running. Since both switches,
FS
and
ES,
are closed,
current flows to clamp lifting magnet HM (Circuit
I).
As a result, the plunger is
attracted
and
the work
clamp
raised.
b. Inserting the
Work
and
Operating
Foot Switch FS
(1st Switch Position]
Insert fabric
and
depress foot control FS to the first switch position. By this
action, circuit I is
opened
and clamp lifting magnet HM de-energized. As a
result, the work clamp is lowered
onto
the work by spring action.
If it should
become
necessary to reposition the work in the machine, simply
remove your
foot
from the control. As
foot
control FS returns to its normal
position, it again closes circuit
I.
As a result, clomp lifting magnet HM is
energized
and
the work
clamp
raised.
c. Starting the Machine by
Operating
Foot Switch FS
(2nd Switch Position)
Press
foot
control FS all the
way
down to the second switch position, This
action closes circuit
II
in
that
current flows through switches FS
and
SS. Electro
magnet
EM is
energized
and
starts the machine only
ofter
the
plunger
in
clamp lifting magnet HM has dropped bock and thereby has closed switch SS.
d. Sewing Cycle
and
Automatic Stopping of Machine
Releose
foot
control
FS.
Immediately on starting the machine, lever B presses
against
switch T
and
opens
it. As a result, the flow of current to clomp lifting
magnet
HM is inter
rupted
at
a second
point
in the circuit
and
the work clamp kept from being
raised inadvertently while the machine is in
operation.
On completion of the sewing cycle, the machine stops automatically. At the
same
time, switch ES is closed so
that
current flows through switch FS to
clamp
lifting
magnet
HM
As a result, the work
clamp
is raised
and
upper
and
lower
threads
trimmed.
The
work
can
be
removed.
