3-8. 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
"contaminated 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 re-
duction 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
pneumatic equipment is used.

Quality of the air supply
When the supply air contains a considerable amount of moisture
Ambient environment
When our machine is installed at a place where the temperature great-
ly 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.
(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 pro-
vided 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.

3-10. Installing the cloth chip bag
1) The cloth chip bag should be installed when
the bird's nest reducing device is used. Refer
to "I-5-3. Bird’s nest reducing device"
p.19 for the description of the bird's nest
reducing device.
2) Attach cloth chip bag ❷(supplied in the ac-
cessory box) to duct ❶.
3) Putting the cloth chip bag on the projection of
duct ❶, zip the bag to secure it.

If the feeding frame comes in contact
with eye protection cover ❶when
the former goes up by its rebound,
install eye protection cover ❶while
shifting it upward.
WARNING :
Be sure to attach this cover to protect the eyes from the disperse of needle breakage.

4. PREPARATION OF THE SEWING MACHINE
4-1. Lubrication
1) Check that the place between lower line B
and upper line A is lled with oil. Fill there
with oil using the oiler supplied with the ma-
chine as accessories when oil is short. (two
locations)
2) Apply one drop of oil to the hook race ❶part
to spread on it.
1. Do not lubricate to the places other than the oil tank and the hook of Caution 2 below.
Trouble of components will be caused.
2. When using the sewing machine for the rst time or after an extended period of dis-
use, use the machine after lubricating a small amount of oil to the hook portion. (For
removing the shuttle, see “III-1-2. Adjusting the needle-to-shuttle relation” p.100.)
The lower oil tank is used for supplying the oil to the hook section. The upper oil tank
is used for supplying the oil to the crank gear section. It is possible to reduce the oil
amount when the number of rotation used is low and the oil amount in the hook portion
is excessive. (Refer to "III-1-12. Amount of oil supplied to the hook" p.116.)

A
Use [JUKI No. 2 oil] (supplied in the accessory box) for your sewing machine.
Capacity JUKI part No.
100-cc bottle B91212200A0
900-cc bottle MDFRX2001L0

WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.

When tightening setscrew ❶, be
sure to use the screwdriver (Part No.
: 40032763) supplied as accessories.
Do not use L-shaped hexagon wrench
key. There is a danger of breaking
setscrew ❶.
WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.

1) Open hook cover ❶.
2) Raise latch ❸of bobbin case ❷, and re-
move the bobbin case.
3) When entering bobbin case, insert it with the
latch tilted until “click” sounds.
4-4. Installing and removing the bobbin case
❶

❷If it is not fully inserted, bobbin case
❷ may slip o󰀨 during sewing.
WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.
WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.
1) Set the bobbin ❶into bobbin case ❷in the
direction shown in the gure.
2) Pass the thread through thread slit ❸of bob-
bin case ❷, and pull the thread as it is. By so
doing, the thread will pass under the tension
spring and be pulled out from thread hole ❹.
3) Pass the thread through thread hole ❺of the
horn section, and pull out the thread by 2.5
cm from the thread hole.
If the bobbin is installed in the bob-
bin case orienting the reverse direc-
tion, the bobbin thread pulling out
will result in an inconsistent state.

4-6. Adjusting the thread tension
Adjusting the needle thread tension
1) Select thread tension tab A
on the sewing screen.
2) Set a needle thread tension using
PLUS/MINUS (+/–) button B. There
is a setting range of 0 to 200. When
the set value is increased, the tension
becomes higher.
* When the set value is 50 at the
time of standard delivery, the thread
tension is adjusted so that H type
is 1.08N and S type is 0.88N (spun
thread #50).
(When thread tension No. 1 is re-
leased)
A
If thread tension controller No. 1 ❶is turned
clockwise, the length of remaining thread on the
needle after thread trimming will be shorter. If it is
turned counterclockwise, the length will be longer.
Shorten the length to an extent that the thread is
not slipped o󰀨.
Adjust needle thread tension from the operation
panel and bobbin thread tension with ❷.

1. When raising the intermediate presser height, turn the pulley by hand to lower the needle
bar, and conrm that the needle bar does not interfere with the intermediate presser. (When
using DP X 5 needle, use the sewing machine with the height of 3.5 mm or less.)
2. Take care not to get your hands and ngers caught in the feeding frame or intermedi-
ate presser.
