Adjustment Procedures Results of Improper Adjustment

1. Start the Test Mode I10 (IP-410).

2. Tread on the start pedal for origin retrieval, and make adjustments by

turning the sensor slit so that the lines combining the center of the intermediate presser lifting shaft , the standard hole of the intermediate presser lifting cam , and the center of the cam follower become almost a straight line.

3. Press of the panel three times. Loosen the first screw of the

drive bevel gear of the intermediate presser variable shaft . Take out the drive bevel gear from the flat part of the intermediate presser variable shaft and move it in the direction of the Arrow A.

4. Using the [+] key or the [–] key , turn the intermediate presser variable

shaft until the second screw of the intermediate presser variable arm settles in the center of the arm’s left-side hole C. (Insert a hexagonal wrench to adjust positioning so that the arm comes in the center of backlash deflection.)

5. Turn the intermediate presser lifting shaft so that the second screw

of the intermediate presser lifting cam comes just above. Press the drive bevel gear of the intermediate presser variable shaft in the direction of the Arrow B to fix it.

6. After the completion of second origin retrieval, press of the panel twice to secure the [timing adjustment position]. In this case, confirm that the second screw of the intermediate presser variable arm is positioned in the center of the arm’s left-side hole C or below it. (If the screw seems to have been positioned above the center, return to Step 4 and repeat the above-mentioned adjustments.)

7. If the second screw of the intermediate presser variable arm is not positioned in the center (or lower), loosen the setscrew of the sensor slit and turn this sensor slit in the direction of the Arrow D for fine adjustments.

8. Make origin retrieval and confirm that the the cam follower is located in the parallel section of the intermediate presser lifting cam

. When the condition has been found normal, fasten the setscrew of the drive bevel gear and the setscrew of the sensor slit

regularly.

(Caution) For the prevention of the sensor from destruction,

make origin retrieval after confirming that the slit of the sensor slit is positioned in the center of the sensor

o There will be a displacement

between the variable value of the intermediate presser lower position and the panel setup value.

o If there is no cam follower in

the parallel section of the intermediate presser lifting cam at the time of origin retrieval, stepping out may occur in the intermediate presser motor, thus causing defective stitches, generation of sound from the face plate section, and destruction of parts.

o If adjustments of backlash are in-

sufficient for the drive bevel gear

, stepping out may occur in the intermediate presser motor, thus causing defective stitches, generation of sound from the face plate section, and destruction of parts. .

1. Turn ON the power supply and set the height of the intermediate presser to 0mm. Turn OFF the power supply in the state that the intermediate presser has been lowered.

2. Loosen the intermediate presser stroke adjusting screw .

3. Turn the pulley and move the needle bar to the lower dead point. When the intermediate presser is lifted and the intermediate presser stroke adjusting screw is moved to the right or left, confirm that the intermediate presser adjusting arm is positioned not to move vertically and that the intermediate presser positioning link keeps a close contact with the arm. In this state, tighten the setscrew of the intermediate presser drive arm. (The clearance is approximately 3.6mm between the intermediate presser needle bar connection and the intermediate presser bar metal

4. After the setscrew has been tightened, confirm that there is no backlash in the intermediate presser adjusting arm in the forward and backward directions.

5. Finally, make adjustments of the intermediate presser stroke. (Refer to Instruction Manual III. MAINTENANCE OF SAWING MACHINE, 1-4. Adjusting the vertical stroke of the intermediate presser.)

o If there is no clearance, there will

be interference between the intermediate presser bar metal and the intermediate presser needle bar connection during sewing machine operation, and this will generate abnormal sound as a result.

o If there is too much clearance,

there will be interference between the intermediate presser adjusting arm and the arm during sewing machine operation, thus generating abnormal sound as a result.

o If there is too much or too less

clearance, the lower dead-point height of the intermediate presser

may be changed as a result of intermediate presser stroke adjustments.

2) Turn the lower shaft rear metal in the direction of the arrow and adjust the backlash, keeping the metal to contact closely with Face A. Size of backlash is 0.1mm at the tip of the driver . The shaft is required to rotate smoothly.

3) Tighten the 2 setscrews .

4) Tighten the 2 setscrews .

(Caution) When eliminate the backlash, the direction of rotation

should always be kept in the direction of the arrow.

2. Lower shaft connection/disconnection

1) Loosen the 2 setscrews .

2) The lower shaft can be taken out if it is pulled in the direction

of the arrow.

3) When mounting the lower shaft , insert it in the lower shaft rear metal and the lower shaft gear . Apply 1 of the setscrews to the flat section of the lower shaft and tighten it approximately in the center. Tighten the remaining setscrew .

*Connection and disconnection of the lower shaft become easy if

the above-mentioned backlash has been relieved in advance. In this case, backlash adjustment must be done after the lower shaft has been installed.

o If the backlash is excessive, the

hook noise will be increased.

o If backlash is too small, the lower

shaft gear or the oscillator will give rise to frictional wear. In addition, this can be a cause of crank rod lock-up.

o If the front or rear position of the

lower shaft rear metal is displaced at the time of backlash adjustment, this can also be a cause of the lock-up of oscillator

or the crank rod.

1. Loosen the 2 setscrews and increase the backlash of the lower shaft gear .

(Caution) 1. If the lower shaft gear has insufficient backlash,

the oscillator does not swing correctly. In such a case, refer to [(13) Lower shaft backlash adjustment and connection/disconnection] and provide a sufficient backlash.

2. The 3 setscrews should have been loosened in advance. In this case, the second screw of the setscrews should be loosened first. Then, the first one can be loosened.

3. Lightly swing the whole body of the oscillator with a finger in the direction of the arrow. Decide the positioning of the oscillator so that it stays in the center of swinging.

4. Loosen the 3 setscrews and then fix them so that the oscillator is not displaced from the center of swinging. (Tighten the first screw first so that it comes in contact flatly with the oscillator shaft . Then, tighten the second one.)

5. Make backlash adjustment for the lower shaft gear , according to [(13) Lower shaft backlash adjustment and connection/ disconnection].

(Cautions)1. In the case of disassembly and adjustment, grease-

up treatment is always needed for the specified places (2 positions) and the gear area A of the oscillator .

2. When the crank rod (under-cam) is removed, actions for under-cam positioning must be taken, without fail. Refer to [(6) Crank rod connection/ disconnection].

o If the position for fixing the

oscillator is inadequate, this can also be a cause of the frictional wear or lock-up of the oscillator pin, crank rod lid, undercam, and the crank rod.

1. Loosen the setscrew and remove it.

2. When the adjusting screw is tightened, the quantity of oil can be regulated for the lubrication pipe left .

3. After adjustments, tighten the setscrew to fix it.

(Cautions) 1. In the state of standard shipping, the hook lubrica-

tion reducer is positioned so that it is lightly tightened and the adjusting screw is return-loosened by 4 turns.

2. When reducing the oil amount, the screw should not be tightened up fully. Tighten the hook lubrication reducer and then return it by two turns. In this position, wait for half a day to see how it goes. Too much reduction can be a cause of hook wear.

o If the amount of hook lubricant is

reduced too much, this can be a cause of frictional wear of the hook race plane or lock-up.

1. Pass the two lubrication pipes and and the oil drain pipe through the frame, and mount the shuttle .

2. Hold the lubrication pipes and with the pipe holder and fix them with the setscrews .

3. Fix the two lubrication pipes and with the cord clamps and the setscrews .

The distance is 139.5 mm between the measuring plane B of the bobbin winder driving wheel and the cover mounting plane

of the sewing machine frame .

(43) Adjusting the bobbin winder amount

The position of the bobbin winder lover is based on the standard that it is 14 mm apart from the bobbin winder shaft . Try to perform bobbin winding actually and make fine adjustments of the bobbin lever set screw in the directions of the arrows A and B so that the amount of thread winding becomes adequate (recommended value: 80 to 90% of the bobbin.)

1. Loosen the 2 setscrews to adjust the position (139.5mm) of the bobbin winder driving wheel and fix it with the 2 setscrews .

o If the distance of 139.5mm is

insufficient, rubber ring wear may occur in the bobbin winder unit. In addition, the bearing life may be reduced in the bobbin winder unit.

o If the distance of 139.5mm is ex-

cessive, normal thread winding may fail. In addition, this will also cause rubber ring slippage in the bobbin winder unit and give rise to wear.

1. Loosen the setscrew of the bobbin winder lever and adjust the distance to 14mm between the bobbin winder lever and the bobbin winder shaft . After that, tighten the setscrew of the bobbin winder lever.

2. Start the sewing machine and wind the thread at the bobbin winder. Confirm the amount of winding.

1) If the amount of winding seems to be too much, adjust the bobbin

winder lever in the direction of the arrow B.

2) If the amount of winding seems to be too less, adjust the bobbin

winder lever in the direction of the arrow A.

3. If the winding state of the thread around the bobbin winder seems to be uneven, loosen the nut and adjust the height of the thread tension control . (Example) If the amount of the wound thread is less on the upper

side of the bobbin winder as illustrated, adjust the thread tension control upwards.

o If too much thread is wound

(thread protruded from the bobbin winder ), the thread will come in contact with the inside of the bobbin case and this can be a cause of sewing deficiency.

o If the amount of thread winding is

uneven at top and bottom of the bobbin winder , stitch perforation may become irregular.

(44) Adjustment of the shuttle upper spring and lower thread holder position

1. Shuttle upper spring : In regard to the right and left positioning, secure coincidence between the center of the needle and that of the groove width C. For the front-rear positioning, join the needle rear end and the corner A block.

2. Lower thread holder : The amount of overlapping with the shuttle upper spring should be adjusted so that the thread of Vinylon #8 can pass smoothly when it is pulled in the direction of the arrow E. After the best positioning has been secured, fasten the 2 setscrews .

(Caution) If Part

and

is damaged, this is the cause of thread breakage, hangnail of thread, stain on thread, etc. Therefore, this part should be polished by the use of a buff or the like. In particular, the rear side should be handled with care.

(45) Shuttle felt

1. Remove the work feed bar, feed plate, and the throat plate. Adjust the positioning of shuttle upper spring with the setscrews (2 pcs.).

2. Using the setscrew , adjust the amount of overlapping D for the lower thread holder and the shuttle upper spring .

(Caution) The right and left positions can also change during (18)

hook adjustments. Position adjustment for the shuttle upper spring should be done after the completion of standard hook adjustment, without fail.

o If there is a front and rear

displacement or a right and left displacement, needle thread biting may occur into the hook. Too much motion to the rear side will cause the moving knife to fail to hook the needle thread.

oToo much motion to the rear side

will cause the moving knife to fail to hook the needle thread.

oToo much motion to the left side

will cause the moving knife to fail to hook the bobbin thread.

1. If the shuttle felt seems to be protruded or it has been replaced with a new one, push it in by means of tweezers or the like.

(Caution) Do not push it in excessively. Align the height and the

plane of the shuttle race .

2. Confirm that the shuttle packing has been mounted assuredly.

o If the shuttle felt is protruded,

this will be turned into a rotary load of the inner hook, causing a sewing error.

o If the shuttle felt is missing or

pushed in too much, this will result in hook lubrication deficiency , causing hook overheating and wear.

o If the shuttle packing has been

missing, the shuttle felt and others may be lost, and this can be a cause of shuttle heating and wear.

(Caution) Set the stroke of the thread take-up spring shorter

for thin threads with thread number #50 or higher.

o If the stroke of the thread take-up

spring is larger than the specified value: Length of remaining needle thread is shortened, causing the needle thread to slip off the needle at the sewing start.

o If the stroke of the thread take-up

spring is smaller than the specified value: Needle thread breakage will occur at the time of thread trimming when using a thin thread.

(Caution) If the thread take-up spring interferes with the L-shaped thread guide , the thread takeup spring may fail to return to the initial position before thread trimming, and the length of remaining needle thread may be short. If such a trouble occurs, bend the section

of the thread take-up spring to widen the clearance
