16 [4] OPERATION OF THE SEWING MACHINE 1. Lubrication Turn OFF th por bfor starting th ork so as to prvnt accidnts causd by abrupt start of th sing machin. A B Chck that th plac btn lor lin B and uppr lin A is filld ith oil. Fill thr ith oil using th oilr supplid ith th machin as accssoris hn oil is short. * Th oil tank hich is filld ith oil is only for lubricating to th hook portion. It is possibl to rduc th oil amount hn th numbr of rotation usd is lo and th oil amount in th hook portion is xcssiv. (Rfr to 8. Amount of oil supplid to th hook of [7] MAINTENANCE.) 1. Do not lubricat to th placs othr than th oil tank and th hook of Caution 2 blo. Troubl of componnts ill b causd. 2. Whn using th sing machin for th first tim or aftr an xtndd priod of disus, us th machin aftr lubricating a small amount of oil to th hook portion. (Rfr to 2. Adjusting th ndl-to-shuttl rlation of [7] MAINTENANCE.) 2. Attaching th ndl Turn OFF th por bfor starting th ork so as to prvnt accidnts causd by abrupt start of th sing machin. Loosn stscr and hold ndl ith th long groov facing toard you. Thn fully insrt it into th hol in th ndl bar, and tightn stscr. If th stitchs ar mad as shon in, attach th ndl facing to th dirction to a small xtnt. 13

17 3. Thrading th machin had Turn OFF th por bfor starting th ork so as to prvnt accidnts causd by abrupt start of th sing machin. Thin synthtic thrad or th lik Pull out th thrad by approximatly 4 cm from th ndl aftr thrading through th ndl. 1. Whn th silicon oil is usd, thrad through thrad guid for silicon (Optional) 2. For thick thrad, pass th thrad through on hol only of ndl bar thrad guid. 4. Installing and rmoving th bobbin cas Turn OFF th por bfor starting th ork so as to prvnt accidnts causd by abrupt start of th sing machin. 1) Opn hook covr. 2) Rais latch of bobbin cas, and rmov th bobbin cas. 3) Whn installing th bobbin cas, fully insrt it into th shuttl shaft, and clos th latch. If it is not fully insrtd, bobbin cas may slip off during sing. 14

18 5. Installing th bobbin Turn OFF th por bfor starting th ork so as to prvnt accidnts causd by abrupt start of th sing machin. 1) St th bobbin into bobbin cas in th dirction 2.5 cm shon in th figur. r 2) Pass th thrad through thrad slit of bobbin t cas, and pull th thrad as it is. By so doing, th thrad ill pass undr th tnsion spring and b pulld out from thrad hol r. 3) Pass th thrad through thrad hol t of th horn sction, and pull out th thrad by 2.5 cm from th thrad hol. If th bobbin is installd in th bobbin cas orinting th rvrs dirction, th bobbin thrad pulling out ill rsult in an inconsistnt stat. 6. Adjusting th thrad tnsion Long Short If thrad tnsion controllr No. 1 is turnd clockis, th lngth of rmaining thrad on th ndl aftr thrad trimming ill b shortr. If it is turnd countrclockis, th lngth ill b longr. Shortn th lngth to an xtnt that th thrad is not slippd off. Adjust ndl thrad tnsion from th opration panl and bobbin thrad tnsion ith. Adjusting th ndl thrad tnsion h 1) Slct thrad tnsion ith ky. 2) St ndl thrad tnsion ith ky or ky. Thr is a stting rang of 0 to 200. Whn th st valu is incrasd, th tnsion bcoms highr. * Th tnsion is st so that 1.5 N (spun thrad #50) is obtaind at th st valu 50 at th tim of standard dlivry. (Whn thrad tnsion No. 1 is rlasd) 15

19 7. Adjusting th thrad tak-up spring Th standard strok of thrad tak-up spring is 8 to 10 mm, and th prssur at th start is 0.1 to 0.3N. 1) Adjusting th strok Loosn stscr, and turn thrad tnsion asm.. Turning it clockis ill incras th moving amount and th thrad draing amount ill incras. 2) Adjusting th prssur To chang th prssur of th thrad tak-up spring, insrt a thin scrdrivr into th slot of thrad tnsion post hil scr is tightnd, and turn it. Turning it clockis ill incras th prssur of th thrad tak-up spring. Turning it countrclockis ill dcras th prssur. 8. Exampl of th thrad tnsion Whn using th sing machin for th first tim, adjust th thrad tnsion rfrring to th tabl blo.

24 5. Winding a bobbin 5-1. To ind a bobbin hil th sing machin is prforming sing Thrad th bobbin indr and ind th bobbin thrad onto th bobbin as illustratd in th figur To ind a bobbin indpndntly 1) Prss ky to mak th SEWING LED go off. 2) Slct th bobbin indr ith ky. h h Slction cannot b prformd hn th Sing LED is lit up. 3) Prss ky. Th ork clamp ft com don and th Sing LED lights up. 4) Whn th pdal sitch is dprssd, th sing machin rotats. 5) Whn th pdal is dprssd again, or ky or ky is prssd, th sing machin stops. 6) Whn ky is prssd, th Sing LED gos off, th ork clamp ft go up and ky bcoms ffctiv. d Bobbin indr dos not ork immdiatly aftr turning ON th por. Prform th bobbin inding aftr stting pattrn No. or th lik onc, prssing th ky, and making th sing LED light up. h 21

25 6. Thrad clamp dvic Troubl of sing (slip-off of ndl thrad, stitch skipping, or stain of ndl thrad) at th tim of highspd start can b prvntd ith th thrad clamp dvic. Th thrad clamp dvic orks in th stat that th thrad clamp indication LED lights up and dos not ork hn th LED gos off. Changovr of ON/ OFF motion is prformd ith ky. Whn th thrad clamp dvic is OFF, th start automatically bcoms th slo start. 1. Whn mmory sitch No. 35 is "1" (prohibitd), th thrad clamp dos not ork. In addition, ky is inffctiv. 2. Mmory sitch, rfr to [8] HOW TO USE THE MEMORY SWITCH. * Mattrs that dmand spcial attntion hn using th ndl thrad clamp dvic (1) In cas of ith th ndl thrad clamp (motion), mak shortr th lngth of ndl thrad rmaining on th ndl at th sing start for us. Whn th lngth of ndl thrad is lngthnd, ndl thrad on th rong sid of matrial is apt to protrud. In addition, hn th lngth is xcssivly lngthnd, th nd of ndl thrad hld by th ndl thrad clamp may b rolld in th sams. 1) In cas of ith th ndl thrad clamp, th 1) standard of th lngth of ndl thrad is 33 to 36 mm. 33 to 36mm 2) Whn ndl thrad is long aftr rplacing thrad or th lik or sing hil holding ndl thrad by hand, turn OFF th THREAD CLAMP ky. 3) 3) Whn th ndl thrad hld ith th thrad clamp is rolld in th sams, do not dra th matrial forcibly and cut th conncting ndl thrad ith th scissors or th lik. Th sams ar not damagd sinc it is th ndl thrad at th sing start. (2) It is possibl to adjust ndl thrad shortr by making th ndl thrad clamp ork hil holding th stabilizd sing at th start of sing and th gathring (bird's nst) of ndl thrad on th rong sid of matrial can b lssnd. Hovr, for th pattrn hich th stitch lngth for natly rolling in ndl thrad is short, ndl thrad may protrud from th rong sid of matrial. Slct ith/ithout thrad clamp rfrring to th itm blo. 1) Whn th sing lngth is short (lss than approximatly 10 mm), th nd of ndl thrad (Right sid) may protrud lik bard vn hn adjusting ndl thrad shortr. 10mm (Wrong sid) Ndl thrad 22

26 (3) Whn th typ of lor plat that matrial dos not com in clos contact ith throat plat is usd, ndl thrad on th rong sid of matrial may b rolld in th sams rgardlss of ndl thrad play or sing lngth.
