the opposite side with a wrench key. Take care
no to allow the screws to slip o󰀨 the mounting
holes after you have removed the nuts.
Put the nuts you have removed in the accessory
box.
5) Aligning the screws with the taps of the X-feed support block, tighten the screws.

at the front side of the sewing machine
See below for how to change the installation
position of the thread stand.
2) Threading method
1. In the case you have installed the thread stand
to the table at the rear side of the sewing ma-
chine
2. In the case you have installed the thread stand
to the head of the sewing machine
6) Connect the cable
guide to the X
feed mechanism.
Then, tighten the
screws.

Check for a
clearance.
After you have set up the right and left
sub tables, check to make sure that there
is a clearance between the tables and the
X-feed mechanism.

3) For switch button (asm.) C, change round
the direction of assembly.
Then, secure it to the aluminum plate of the
front table (right) with T-head screw Aand
nut B.
Secure the switch button (asm.) so that its
three switch buttons are faced upward.

4) For the laser type model, also change instal-
lation of the power switch as shown in the
gure.
Changes described in the
aforementioned steps 3) and 4) may
not be carried out depending on the
usage.
3-1-7. Points to be checked and precautions to be taken before turning the power ON
1) Place accessory levels at the four corners of
the main table and adjust the table so that the
sewing machine is level.

2) Inspect whether the electrical components and
pneumatic components are correctly assembled.
3) Inspect whether the needle entry point is cor-
rectly aligned with the center of the needle hole
in the throat plate of the sewing machine.
4) Inspect whether the X-feed mech-
anism operates smoothly.

3-1-8. Installing the air hose
1) Connecting the air hose
Connect the air hose to ❶.
WARNING :
Check to be sure that the air hose is fully inserted into the air cock before supplying the air to the
machine so as to prevent the air from being blown directly to the human body. Then, carefully open
the air cock.
2) Adjustment of air pressure
Pull up air regulating knob ❷. Then, turn it to
adjust the air pressure to 0.5 - 0.6 MPa.
Then, push down air regulator knob ❷.
Pull up air regulating knob ❸. Then, turn it to
adjust the air pressure to 0.15 MPa.
Then, push down air regulator knob ❸.

3-1-9. Cautions for the compressed air supply (source of supply air) facility
As large as 90 % of failures in pneumatic equipment (air cylinders, air solenoid valves) are caused by "con-
taminated air."
Compressed air contains lots of impurities such as moisture, dust, deteriorated oil and carbon particles. If
such "contaminated air" is used without taking any measures, it can a cause of troubles, inviting reduction in
productivity due to mechanical failures and reduced availability.
Be sure to install the standard air supply facility shown below whenever the machine provided with pneumat-
ic equipment is used.

When the supply air contains a considerable amount of moisture
Ambient environment
When our machine is installed at a place where the temperature greatly
changes in the morning and in the evening from that in the daytime or
freeze is like to occur.
In the aforementioned cases, be sure to install an air dryer.
When the supply air contains a considerable amount of carbon
and dust
(Most troubles in the air solenoid valves are caused by carbon.)
Be sure to install a mist separator.

Cautions for main piping
• Be sure to slope main piping by a falling gradient of 1 cm per 1 m in the direction of air ow.
• If the main piping is branched o󰀨, the outlet port of the compressed air should be provided at
the top part of the piping using a tee in order to prevent drain settling inside the piping from
owing out.
• Auto drains should be provided at all lower points or dead ends in order to prevent the drain
from settling in those parts.

3-1-10. Checking the needle entry point and hook timing
* When the power to the sewing machine is in the
ON state, reset the sewing machine rst.
1) First, remove the auxiliary disk presser and the
intermediate presser.
Check the alignment of the needle entry point of
the sewing machine with the center of the throat
plate. (Check the direction of 360 degrees.)
2) Remove the throat plate and check the hook
timing. (Check the hook timing in all 360 de-
grees.)
