Before choosing a part
Start with these documented details. Read the requirements with each answer before choosing a needle, bobbin or foot.
GROZ-BECKERT 135 x 17 needles, sizes Nm 125 to Nm 180 (standard Nm 160), with thread #30 to #5 (US: #46 to #138; Europe: 20/3 to 60/3).
Requirements and sources →Not yet confirmed here: Manufacturer accessory group, Presser-foot shank type, Foot attachment, Foot holder / mount, Foot interface / generation, Bobbin type / class, Bobbin material, Bobbin diameter, Bobbin height, Hook type, Maximum stitch / zigzag width, Feed system, Bobbin loading direction. What is still to confirm →
Other names, regional versions and related models have not been confirmed here. A shared manual, product line or accessory group does not identify the machine's family.
These are the values in the specification column for the LU-1508N and LU-1509N; the LU-1508NH and LU-1509NH column lists other needles and threads, which do not apply. The manual names no other needle system or substitute, and none is inferred.
Documents and page references →The hook wording is quoted from the English specification table only; the manual’s other language tables describe it differently. No bobbin part number, size, class or material and no replacement hook or bobbin case is named; that is not stated, not incompatible.
Documents and page references →Turn the power off and check that the motor has completely stopped before adjusting the bobbin thread tension. Apply the same tension to both No. 2 thread tension nuts. The manual gives no tension values.
Documents and page references →The lift figures are in a specification row that covers all four models in the manual. No presser-foot or walking-foot part number, mount or third-party foot fit is stated.
Documents and page references →The 9 mm figures are from the column shared by the LU-1508N and LU-1509N; the 10 mm figures for the LU-1508NH and LU-1509NH do not apply. Stitches longer than 6 mm lower the maximum sewing speed.
Documents and page references →No. Do not exceed the value in the sewing speed table on PDF page 86 (printed page 44) for your stitch length and walking-foot movement, and run it at 2,000 sti/min or less for the first month. The LU-1508NH and LU-1509NH figures do not apply.
Documents and page references →Turn the power off and check that the motor has completely stopped first. Use “5. ATTACHING THE NEEDLE” on PDF page 62 (printed page 20). The needle-to-hook clearance check it refers to is an adjustment procedure and is not covered here.
Documents and page references →Turn the power off and check that the motor has completely stopped first. Use only the illustration labelled “LU-1508N / LU-1509N” on PDF page 68 (printed page 26); the LU-1508NH / LU-1509NH path on PDF page 70 (printed page 28) is not for this model.
Documents and page references →Turn the power off and check that the motor has completely stopped first. Use sections 6 and 7 on PDF pages 64–65 (printed pages 22–23). Never run the machine idle with the bobbin in it: for a test run, remove the bobbin and the needle thread.
Documents and page references →Keep the pressure as low as possible while the foot still holds the material securely, and tighten the nut after adjusting (PDF page 76, printed page 34). The manual gives no pressure value.
Documents and page references →Turn the power switch off before removing the belt cover or V belts, and never run the machine without the belt cover and finger guard. The rows are the manual’s LU-1508N and LU-1509N rows; it gives no belt, pulley or motor part number.
Documents and page references →Turn the power off and check that the motor has completely stopped before oiling. The oil points are the arrows on PDF pages 58–59 (printed pages 16–17). Adjusting the hook oil amount (PDF page 61, printed page 19) is an adjustment procedure and is not covered here.
Documents and page references →Turn the power switch off and remove the knee lifter hook before tilting the machine head. For the first month, run it at 2,000 sti/min or less. The checks are on PDF page 43 (printed page 1).
Documents and page references →Remove the cause first, then turn the power off and check that the motor has completely stopped. Follow the reset steps exactly as printed on PDF page 91 (printed page 49); outside this reset, do not let the machine turn in reverse.

GROZ-BECKERT 135 x 17 needles, sizes Nm 125 to Nm 180 (standard Nm 160), with thread #30 to #5 (US: #46 to #138; Europe: 20/3 to 60/3).
Turn the power off and check that the motor has completely stopped first. Then follow the four steps under "5. ATTACHING THE NEEDLE" on PDF 62 / printed 20, which include how the needle must face.
Turn the power off and check that the motor has completely stopped first. Then thread in the numbered order shown in the illustration labelled "LU-1508N / LU-1509N" on PDF 68 / printed 26. The illustration labelled "LU-1508NH / LU-1509NH" on PDF 70 / printed 28 shows a different path and is not for this model.
The English specification table lists a vertical-axis 2.0-fold capacity hook, in a row that covers all four models in the manual. The manual names no bobbin part number, size, class or material.
Turn the power off and check that the motor has completely stopped first. (the safety page also says to turn the power off when replacing the bobbin). Then follow "6. ATTACHING AND REMOVING THE BOBBIN" on PDF 64 / printed 22 and "7. THREADING THE HOOK" on PDF 65 / printed 23. Check: when you draw the thread, the bobbin must revolve in the direction of the arrow shown there.
The presser foot lifts 9 mm with the hand lifter lever and 16 mm with the knee lifter. To keep the foot raised, lift the hand lifter in the direction of the arrow: the foot rises 9 mm and stays there. Lower the hand lifter to bring the foot back down.
Turn the presser spring regulating dial clockwise to increase the presser-foot pressure or counterclockwise to decrease it, then tighten the nut. Run the machine with the pressure as low as possible while the presser foot still holds the material securely.
Specifications apply to the named model and document edition. Read any setup, fabric or safety requirements with the answer.
Not in every setting. The maximum is 2,500 sti/min, but the manual's sewing speed table limits it by stitch length and by the amount of alternate vertical movement of the walking foot and presser foot. Less than 3 mm: 2,500 sti/min with stitches of 6 mm or less, 2,000 sti/min with stitches over 6 mm up to 9 mm. 3 mm to less than 4 mm: 2,000 sti/min for either stitch range. 4 mm to less than 6.5 mm: 1,600 sti/min for either. Do not exceed the value for your sewing conditions.
Use JUKI New Defrix Oil No. 2. Once a day, apply an adequate amount of oil to the points marked with arrows on the face plate portion (the manual's steps for opening it are on PDF 58 / printed 16) and on the other parts (PDF 59 / printed 17). Tank C takes 5 ml of oil a week. Before first use or after a long period of disuse, also oil each felt and oil wick after removing the top cover. Too much oil may cause leakage. In the oil reservoir, keep the oil surface 1 mm above the top of the sponge; about 500 cc is needed, and oil poured in all at once may overflow.
Before first use after set-up, clean the machine thoroughly, remove the dust from transport and oil it well. Confirm that the voltage is set correctly and the power plug is properly connected, and never use it on a voltage other than the designated one. Normal rotation is counterclockwise as seen from the pulley side; do not let it turn in reverse. Never run it unless the head base has been filled with oil. For a test run, remove the bobbin and the needle thread. Operate the handwheel only after the machine has completely stopped.
The maximum stitch length is 9 mm in normal feed and 9 mm in reverse feed. To set it, turn the stitch dial until the number for the length you want is at the top, at the marking spot. Reverse stitches are sewn for as long as you hold the reverse feed control lever down; release it to return to normal feed.
Use an M type V belt and a 3-phase 400 W (1/2 HP) clutch motor, 2-pole or 4-pole. For the LU-1508N (2,500 sti/min; handwheel effective diameter φ 93.3 mm) the manual pairs: 2-pole, 50 Hz, 2,840 rpm: motor pulley φ 80, belt M 44; 2-pole, 60 Hz, 3,400 rpm: φ 65, M 43; 4-pole, 50 Hz, 1,430 rpm: φ 160, M 47; 4-pole, 60 Hz, 1,715 rpm: φ 135, M 46.
If too much load reaches the hook or other parts while sewing, the safety clutch operates, and the hook will not rotate even when you turn the handwheel. Remove the cause, then, with the power off and the motor completely stopped, follow the reset steps on PDF 91 / printed 49. The reset is complete when the handwheel clicks; then turn the handwheel by hand and confirm that the push button has returned.
Needle thread tension is set at thread tension nut No. 2, and bobbin thread tension at the tension adjustment screw. Follow the manual's steps on PDF 72 / printed 30 (needle thread) and PDF 73 / printed 31 (bobbin thread).
Use the full source procedure and its safety precautions. A short referenced answer is not a substitute for service documentation or qualified electrical/mechanical repair.
Service-manual availability and service-only procedures remain unestablished unless separately cataloged and reviewed.
Answers use this model’s own instruction manual with its stated safety conditions. Where the manual contradicts itself or gives no value, no answer is given. No hands-on testing or replacement-part fit is claimed.
An unanswered question does not mean a part is incompatible. We have not confirmed enough information to recommend it.
Other names, regional versions, production history, further specifications and documents are not fully covered here. Their absence is not a “none exist” finding.
