3-3. Adjusting the height of the knee lifter

WARNING :

To protect against possible personal injury due to abrupt start of the machine, be sure to start the following work after turning the power off and ascertaining that the motor is at rest.

1) The standard height of the presser foot lifted using the knee lifter is 12 mm.

2) You can adjust the presser foot lift up to 13 mm using knee lifter adjust screw 1.

Do not operate the sewing machine in the state that the presser foot 3 is lifted by 12 mm or

more since the needle bar 2 comes in contact with the presser foot 3.

3-4. Installation of thread stand

Assemble the thread stand, set it up on the machine

table using the installation hole in the table and

tighten nut 1 gently.

300 mm from the top

surface of table

4. PREPARATION OF THE SEWING MACHINE

4-1. Method of lubrication

For this sewing machine, one of two different lubricating methods can be selected.

(1) Method of circulating lubrication (when the oil collected in the under cover is reused)

Lubrication to hook side

Reux oil

from hook

Filter for plunger

To ensure the long service life of the sewing machine, be sure to clean up the aforementioned

lter sections (at four locations) periodically (approximately once three months). When the lter

is clogged, lubrication trouble will occur and break-down will be caused. In addition, when the oil becomes dirty, replace the oil gathered in the oil tank and the under cover.

Plunger

Urethan lter

Lubrication

Oil tank

Ball oat case

Oil inlet lter

Circulation

Filter for

circulation

(2) Method of non-circulation type lubrication (when only the clean oil is always used)

Insert inlet port 1 for circulation into section 3 of

the feed box cover until it will go no further to put it

into the state as it has been delivered to your plant.

* Drain oil dropped into the under cover by remov-

ing drain screw 2.

When inlet port for circulation 1 comes

in contact with the oil surface, oil is

absorbed without passing the lter. As a

result, break-down will be caused.

If inlet port 1 for circulation is not insert-

ed into the feed box cover, oil may leak

from inlet port 1 for circulation or the

quantity of oil in the hook may uctuate.

Page 10

4-2. Lubrication to the oil tank

WARNING :

1. Do not connect the power plug until the lubrication has been completed so as to prevent accidents due to abrupt start of the sewing machine,

2. To prevent the occurrence of an inammation or rash, immediately wash the related portions if

oil adheres to your eyes or other parts of your body.

3. If oil is mistakenly swallowed, diarrhea or vomitting may occur. Put oil in a place where children cannot reach.

Lower

engraved

marker line

Upper engraved marker line

Fill the oil tank with oil for hook lubrication before

operating the sewing machine.

1) Remove oil hole cap 1 and ll the oil tank with

JUKI NEW DEFRIX OIL No.1 (Part No. : MD-

FRX1600C0) or JUKI MACHINE OIL #7 (Part

No. : MML007600CA) using the oiler supplied

with the machine.

2) Add oil until the top end of oil amount indicating

rod 3 does not go above the upper engraved

marker line.

If the oil tank is lled with an excessive amount

of oil, oil will leak from the air vent hole in the ball

oat case or proper lubrication will not be carried

out. So, be careful.

3) When you operate the sewing machine, rell oil if

the top end of oil amount indicating rod 3 comes

down to the lower engraved marker line of oil

amount indicating window 2.

• For the rst time you ll the oil tank with oil, add 280 cc of oil as a guide and check to be sure

that the oil amount indicating rod works. If the oil amount indicating rod does not work, bring it

to the workable state by tiling the sewing machine once.

• When you use a new sewing machine or a sewing machine after an extended period of disuse,

use the sewing machine after performing break-in at 2,000 sti/min or less.

• For the oil for hook lubrication, purchase JUKI NEW DEFRIX OIL No. 1 (Part No. : MD-

FRX1600C0) or JUKI MACHINE OIL #7 (Part No. : MML007600CA).

• Be sure to lubricate clean oil.

In case of the circulation type lubrication method, when using the sewing machine for the rst time, the oil amount in the oil tank decreases until the oil has collected in the ler for circulation.

When the top end of oil amount indicating rod is lower than the lower engraved marker line, add

the oil to the oil tank again so that the top end enters between the upper and lower engraved

marker lines.

4-3. Draining of oil from the oil tank

WARNING :

1. To prevent accidents caused by abrupt start of the sewing machine, do not connect the power plug until draining of oil has been completed.

2. To prevent the occurrence of an inammation or rash, immediately wash the related portions if

oil adheres to your eyes or other parts of your body.

3. If oil is mistakenly swallowed, diarrhea or vomitting may occur. Put oil in a place where children cannot reach.

When draining oil from the oil tank, loosen and re-

move oil conrming window 1.

Oil may burst out from the oil conrming

window at the time of draining.

It is recommended, in this case, only to

loosen the oil conrming window instead

of removing it. Then, drain oil while con-

trolling the oil amount bursting out from

the oil amount conrming window 1.

4-4. Adjusting the amount of oil in the hook

WARNING :

To protect against possible personal injury due to abrupt start of the machine, be sure to start the following work after turning the power off and ascertaining that the motor is at rest.

Oil amount

decreases

Adjust the amount oil using adjusting screw 1. Turn screw 1 clockwise to increase the amount of oil in the

hook or counterclockwise to decrease it. Measure the amount of oil in ve seconds. When the amount of oil

is excessively decreased, break-down will be caused. So, be careful.

6-12. Replacing the bobbin thread slack preventer spring

(For LH-3568A,

3568A-7, 3588A and 3588A-7)

1) Loosen screw 1 and remove bobbin thread

slack preventer spring 2 from the groove on the

bobbin case.

Groove

2) Fit bobbin thread slack preventer spring 2 which

replaces the removed spring in the bobbin case

through the groove.

or the spring.

6-13. Stop of the needle bars and angle of corners for corners stitching

(For LH-3568A, 3568A-7, 3588A and 3588A-7)

• Stop of the needle bar

When change lever 1 is moved to position L, the left-hand needle bar stops, and when it is moved to position R, the right-hand needle bar stops.

(3/16" gauge)

3 stitches

90˚

3 stitches

• When returning to 2-needle operation

Press change xing lever 2. Change lever 1 re-

turns to the position "0", and the machine returns to 2-needle sewing.

• Relation between the angle of corners and

stitch length

To perform corner stitching with accuracy, the stitch length can be determined referring to the table of the number of stitches by gauges. However, check whether the stitch length determined really matches the corner by actually sewing it.

(Example)

To sew a correr of 90˚ of angle using a 3/16" gauge with the stitch length specied to 1.6mm, the number

of stiches can be obtained in the following way. Ob-

serve the "90˚" columns on the table of the number

of stitches by stitch length gauges to search for the column in which "1.6" is indicated. Then, you can

nd "3" on the top of the "1.6" lines. This means the

number of stitches is 3.

• If sewing a corner of which angle is 40˚ or less, the thread take-up amount of the bobbin thread slack preventer spring will be insufcient. In this case, the thread will remain on the wrong side

of the material.

• When performing the operation of changeover of separately driven needle bar, perform the work after stopping the sewing machine once.

When the operation of changeover is performed at 1,000 sti/min or more, break-down will be

caused.)

• When the sewing machine is used as the substitute for 1-needle sewing machine in the state of separately driven needle bar, break-down of the sewing machine will be caused. When performing sewing with 1-needle sewing machine, remove one of two needles and use the sewing machine in the state that two needle bars operate.

9. TROUBLES AND CORRECTIVE MEASURES

TROUBLES CAUSES CORRECTIVE MEASURES

1. Thread breakage (Thread is untwisted

or scraped.)

(Needle thread 2 to

3 cm is left on the wrong side of the fabric.)

(Bobbin thread

comes out of the bobbin.)

2. Stitch skipping

There is a sharp edge or burr on

the thread path, needle point, hook blade point or bobbin case resting groove on the throat plate.

Needle thread tension is too high.

Bobbin case opening lever

provides an excessive clearance at the bobbin case.

Hook blade point hits the needle.

Hook is not lubricated properly.

Needle thread tension is too low.

Thread take-up spring is too tight

and its stroke is too small.

Needle-to-hook timing is wrong.

Thread untwines.

Uniform thread loops cannot be

formed when making chain-off thread.

Bobbin is wound with excessive

amount of thread. (In particular,

lament thread)

Clearance between the needle and

the hook blade point is too great.

Needle-to-hook relation is wrong.

Pressing force of the presser foot

is not enough.

Needle bar height is wrong.

Needles are a little too thin.

Synthetic thread or thin thread is

used.

Stitch skipping occurs at the

beginning of sewing.

Stitch skips when sewing

multilayered parts of the material.

Stitch skipping occurs when the

material thickness changes, i.e., from a two-ply part to a multilayered part and vice versa.

Remove sharp edge or burr using a ne

™

sandpaper. Polish the surface of the bobbin case resting groove on the throat

plate using a bufng wheel.

Adjust the needle thread tension.

™

Reduce the clearance.

TROUBLES CAUSES CORRECTIVE MEASURES

3. Loose stitch

4. Thread trimming failure

5. Amount of idling is excessively large.

6. Clamp failure

Bobbin thread does not pass

through the forked end of the tension spring on the bobbin case.

Thread path has rough surface.

Bobbin does not spin smoothly.

Bobbin case opening lever

provides too much clearance at the bobbin.

Bobbin thread tension is too low.

Bobbin is wound too tightly.

The presser foot does not securely

press the multi-layered section of the material.

Needle eyelet is too small for

thickness of thread, preventing smooth take-up motion of the thread take-up lever.

With respect to tensing of thick

thread, neither needle thread tension nor bobbin thread tension can be increased, resulting in production of isolated idling loops.

Isolated idling loops are produced

during the reverse feed stitching.

The position of the moving knife is

1

not correct. Bobbin thread cannot be trimmed

2

by dropping the thread trimmer.

The counter knife pressure is

inadequate.

Backlash between the bobbin and

the bobbin case is excessively large.

The idling prevention spring does

not work adequately.

The idling prevention sheet is not

placed.

Thread trimming speed is too high.

The clamp pressure has adjusted

1

to an excessively high or low value. The clamp pressure works

2

excessively, resulting permanent set in fatigue of the clamp plate clamp spring. The bobbin thread slips off due to

3

the bobbin thread slack prevention spring of the cap hook. Due to difference in thread count

4

number between the needle thread and bobbin thread, they excessively tangle with each other at the time of thread trimming.

The feed dog height is too low.

Thread the bobbin case correctly.

™

Remove rough surface using a ne

™

sandpaper or polish the surface using a

bufng wheel.

Replace the bobbin or the hook.

™

Refer to

™

guide", p. 37

Adjust the bobbin thread tension.
