due to outgassing.
Never lift the sewing machine in such a state since the machine can drop to pinch hands,
ngersandarmsresultinginseriousinjury.
* Be sure to fully understand "10.(14) Standard of replacing time of the gas spring" P.63 and
"10.(15) Replacing the gas spring" P.63 before putting the sewing machine into operation.
2. Inordertopreventpinchingofhands,ngersandarmsthatcanresultinaseriousinjury,be
sure to strictly observe the following when carrying out work.
2-1. Be sure to hold the rib on the bed periphery when holding the sewing machine.
2-2. Be sure to lock the hinge stopper to firmly secure the sewing machine in its raised
position.

3) When returning the sewing machine, support
periphery ribs ❶of the machine bed with your
left hand, hold grip ❹of the hinge stopper
section with your right hand, pull it to this side
(direction A) to release the lock and slowly
lower the sewing machine after confirming
that there is no tool such as screwdriver and
the like in the bottom cover.

2) When raising the sewing machine, push feed base ❷away from you (in the direction of the arrow),
then hold periphery ribs ❶located on the front side of the sewing machine bed to slowly lift it.
At this time, do not hold feed base ❷and feed guide shaft fixing base ❸.
DANGER :
1. Do not hold any part other than periphery ribs ❶of machine head.
2. Conrmthathingestopper❹is locked with support shaft ❺.
CAUTION :
If you raise the sewing machine from its home position with the feed base remained near side,
thefeedbasecanmovetopinchhandsandngersleadingtoanunexpectedinjury.
DANGER :
1. Do not lower the sewing machine
while keeping pulling the hinge stop-
per in direction A, in order to prevent
pining of fingers, hands and arms
under the sewing machine leading to
a serious injury.
2. Do not hold feed base ❷and feed

5) The sewing machine stops once more at the
final stage of lowering for the safety. Support
the periphery ribs of machine bed with your
left hand, hold the grip of hinge stopper sec-
tion with your right hand to release the lock
and slowly lower the sewing machine follow-
ing the description of step 3).
Fix operation panel base ❶at the dotting punch
section on the machine table with wood screw ❷.
Protection vinyl is coated on the surface
of the operation panel. Remove it.
1) Assemble thread stand unit ❶.
2) Insert it in the hole located in the rear of the
machine table, and tighten locknut ❷to fix
the thread stand.
When the ceiling wiring i s possible, pass
the power cord through the spool rest
rod.
DANGER :
Take care to prevent pinching of hands
and fingers between the sewing machine
and the bottom cover. In particular,
never lower the sewing machine holding
parts other than the bed rib with two or
more workers, since doing so can cause
pinching o f hands, fingers and arms
leading to a serious injury.

When installing the presser unit ❺,
insert correctly thread t rimming driving
arm roller ❼into the concave in looper
thread trimming cylinder click ❻. If the
roller is off, the looper thread trimming
unit interferes with the throat plate during
sewing. As a result, component breakage
will be caused.

■How to remove
1) Turn clamp holding plate ❶to remove from
presser plate ❺.
2) Lifting presser plate ❺, remove it so as to
draw it.
When moving the feed base by hand, or
removing/at taching the presser unit ,
be careful so that the cloth cutting knife
does not come in contact with the holding
plates, orthe thread trimming unit does
not come in contact with the throat plate.
■How to install
1) Install the presser unit so that presser lever ❸
fits in the letter “U” of presser base ❷.
2) Adjust the hole of presser plate ❺to cloth
open pin ❹.
3) Turn clamp holding plate ❶to hold presser
plate ❺.
It is comparatively easy to install or
remove the presser unit by moving feed
base ❻to the cloth cutting position.
([ ] button is convenient. Refer to
"6.(6) Performing threading" P.21.)
When moving feed base ❻by hand, fol-
low the aforementioned caution.
