WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.
CAUTION :
When handling the lubricating oil or grease, wear safety goggles and protective gloves to prevent
the lubricating oil or grease from coming in contact with the skin. The lubricating oil and grease
can cause inammation on skin if contacted. In addition, never swallow or eat the lubrication oil
and grease. The lubricating oil and grease can cause diarrhea or vomiting.
Refer to "I-4-1. Lubrication" p.9 in the Instruction Manual for the AMS-224EN for the
additional information.

Unclamped state Clamped state
1) Fit projection ❷ of sewing cassette ❶ into the slit on auto-ejector ❸. Now, sewing cassette ❶ is
automatically clamped.
2) To unclamp the sewing cassette, press UNCLAMP switch ❹.
3) Check that the sewing cassette is clamped. Then, press two two-hand control start switches ❺
simultaneously to start sewing.
When starting sewing, check to be sure that the sewing cassette is securely xed in position.
・
If not, personal injury or sewing machine breakage can be caused.
If a clamp fault such as the slip-off of the clamp is detected during sewing, the sewing machine
・
makes an emergency stop and the panel displays the message "PAUSE switch is pressed".
In this case, however, the RESET button is not displayed. In this case, turn the power
switch OFF, close the air cock to discharge air (refer to "I-3-4. Installing the air hose" p.4).
Remove the sewing cassette and turn the power switch ON. After having removed the cause of
the clamp fault, carry out sewing again following the steps of procedure from step 1).
If you turn the power switch OFF when the auto-ejector is in the unclamped state, the au-
・
to-ejector carries out clamping. So, be careful to protect ngers and other parts of your body
against pinching by the auto-ejector.
In the case of a faulty clamping (pinching of foreign matters, inadequate insertion of the
・
sewing cassette), the sewing machine will not start sewing even if you press two two-hand
control start switches ❺ simultaneously. In this case, press UNCLAMP switch ❹ to release
the sewing cassette from the clamped state, remove the cause of faulty clamping, and start
sewing again following the steps of procedure from step 1).
Be aware that hands or ngers can be caught in opening A of the throat plate auxiliary cover
・
during sewing or when the feed is brought forward by jump operation.
4) After the sewing, the auto-ejector automatically pushes out the sewing cassette to complete the sewing.
5) To temporarily stop the sewing machine during sewing, press PAUSE switch ❻.
6) To stop the sewing machine in the event of an emergency, press POWER switch ❼ which is also
used as EMERGENY switch.

III. MAINTENANCE OF SAWING MACHINE
1. MAINTENANCE
1-1. Adjusting the height of the needle bar (Changing the length of the needle)
WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.

❶
* Turn ON the power once, and turn OFF the power again after making the intermediate presser
in the lowered state.
1) Bring needle bar ❶ down to the lowest position of its stroke. Loosen needle bar connection screw
and adjust so that the upper marker line ❸ engraved on the needle bar aligns with the bottom
❷
end of the needle bar bushing lower ❹.
2) As illustrated in the above gure, change the adjusting position in accordance with the needle
count. (The standard needle count is DP x 17 (B point), #24.)
* If sewing problems such as stitch skipping and thread breakage when the needle bar is set at the
standard position, the problems may be xed by nely adjusting the needle bar height within the
range of one marker line.
After the adjustment, turn the pulley to check for an extra load.
1-2. Adjusting the needle-to-shuttle relation
WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.
* Turn ON the power once, and turn OFF the
power again after making the intermediate

2) Loosen setscrew ❽ in the driver. Drawing
bobbin case opening lever hook ❾ toward
you, open it to the right and left until bobbin

3) Adjust so that the point of shuttle meets the
center of needle , and that a clearance of 0
mm is provided between the front end face of
driver and needle as the front end face of
driver receives needle to prevent the needle
from being bent. Then tighten setscrew ❽.
4) Loosen shuttle race screw , and adjust the
longitudinal position of the shuttle race. To
do this adjustment, turn shuttle race adjust-
ing shaft clockwise or counterclockwise to
provide a 0.05 to 0.1 mm clearance between
needle and the blade point of shuttle .
5) After adjusting the longitudinal position of
shuttle race, further adjust to provide a 8 mm
clearance between the needle and the shuttle
race. Then, tighten screw of shuttle race.
Carefully protect against personal injury caused by a possible contact with the sewing
machine strut, switch, etc.
The cushioning materials are adhered on the sewing machine strut, switch, etc. in order to avoid per-
sonal injury.
Inspect the cushioning materials before the operation of the sewing machine for peeling and any other
defects. Change the cushioning material with a new one if it has peeled off or has any defect.

1-9. Needle cooler unit
❶
Thread breakage due to the rise in the needle
temperature can be prevented by the use of the
needle cooler unit.
1) The needle cooler unit blows compressed air
to the needle through air nozzle ❶ and stops
blowing simultaneously with the completion of
sewing.
2) Turn ow regulating valve ❷ to fully open it,
then give it two turns in the reverse direction.
This procedure is the reference for the adjust-

Refer to"III-2-1. Table of Needle hole guide" p.115 in the Instruction Manual for the AMS-
224EN.
When the φ3 mm needle hole guide with counterbore (B242621000G) is used, well-tensed
seams are produced. However, isolated idling loops may be produced in the case the needle penetrates the bobbin thread for some type of the material and thread. If such a trouble
occurs, use the φ3 mm needle hole guide (B242621000F).

When the thread is not adequately tensed, use
the silicon oil tank asm. (40097301).
The silicon oil tank asm. should be fixed on the
sewing machine by means of setscrews ❶ (SM-
4041055SP) and ❷ (SM4042055SP) supplied with
the unit. To tighten setscrew ❷, tighten it together
with thread guide collar ❸ (11315108), silicon oil
tank thread guide ❹ (40010414) and thread guide
setscrew washer ❺ (WP0501046SC). Silicon oil
tank thread guide ❹ (40010414) should be placed
so that it is in parallel with silicon oil tank base ❻
(40096982).
