3-1. Installing the extension plate and the power switch
1. Do not lean over extension plate
❶
or push it by hand so as to prevent
bodily injury due to abrupt lowering of
extension plate
❶
.
2. When returning extension plate
❶
to its raised position from the tilted
position, take care not to allow your
hands and ngers to be caught in it.
3. When loosening toggle clamp
❼
,
slowly lower it while supporting
extension plate

by hand. Never let
the toggle clamp fall freely in order to
prevent bodily injury.
4. Do not place any heavy object on the
extension table sections.
1) Insert pin
A
of positioning plate
❷
into the hole
in extension plate
❶
. Then, secure the pin with
hexagon socket head screw
❸
and washer
❹
.
2) Attach toggle clamps
❼
respectively to left exten-
sion plate
❺
and right extension plate
❻
. Then,
secure them respectively with hexagon socket
head screw
❸
and washer
❹
.
3) Firstly, detach power switch (asm.)
from main
table
❾
. Align the position of left extension plate
❺
and right extension plate
❻
with the position
of main table
❾
. In this state, secure the exten-
sion plates and the main table using table support
bracket
❽
and bobbin winder device mounting
plate
with hexagon socket head screws
❸
and
washers
❹
. At this time, carefully align the outer
peripheries of left extension plate
❺
and of right
extension plate
❻
with the outer periphery of
main table
❾
and adjust them so that no clear-
ance is provided between the extension plates
and the main table.

❶
and main table
❾
are
correctly positioned, x extension plate

with
hinge
using hexagon socket head screws
❸
and washers
