Education DepartmentTraining Workbook: HAPPY HCS-1201 Voyager Operations and MaintenanceRecoveringg From Sewingg InterruptionspYour machine remembers the last-sewn stitch and position after most sewing interruptions, including threadbreaks, hoop strikes, or shut-down. As long as the garment remains hooped, there is a good chance you canresume sewing once you’ve fixed the problem. Note: Sudden power loss or emergency shut-down may resultin slight mis-alignment.General Steps for Recovering from Sewing Interruptions1. Fix the problem. Repair thread break/ replace needle, clear any blockage of thread or broken needle. Check that the bobbin andneedle are re-threaded properly.2. Verify sewing position. If the current needle does not appear to be over the correct position to resume sewing, press FUNC, thenarrow down to POSITION, and press SET. If the sewing arm has been moved off the current sewing position, the carriage shouldreturn to this position now; otherwise it will not movemove. The stitch counter should also now reflect the current sewing positionposition.3. Back up if necessary. To overlap slightly to prevent gaps, press the STOP key until the satisfied.4. Press START to resume sewing.If the Garment Has Become Mis-AlignedgIf you find the machine is slightly off-alignment when resuming sewing, follow this procedure:1. Make note of the current sewing position (stitch#). At this point, also make a mental note (best-guess) of how far off the sewingposition is, and in what direction.2. Return to the design Origin position. Do this by pressing the FUNC key, selecting ORIGIN, and pressing SET.3. Adjust the position of the hoop using the arrow keys based on your guess in step 1.4. Return to the stitch # of the last-sewn position by pressing MENU, choosing POSITION, and pressing SET. Arrow down to thethird option (stitch #), enter the stitch # from step 1 using the arrow keys and press SET. The sewing arm will now move to the lastsewn position. Press ESC to return to the main (drive) screen.5 Test-sew5.Test sew or trace to verify before resuming sewing.sewing If youyou’rere still slightly offoff, repeat steps 11-44 aboveabove.Chapter 4: Troubleshooting & Maintenance2

Education DepartmentTraining Workbook: HAPPY HCS-1201 Voyager Operations and MaintenanceBasic Troubleshooting:g Thread BreaksWe’ve listed the most common causes for thread breaks are listed in a flowchartbelow, in order of frequency. Learn this checklist to keep your machine sewingtrouble-free.Thread Breaks: Other CausesSometimes less-obvious causes maycontribute These regular maintenancecontribute.steps will further reduce causes forthread break:Thread BreakIs the threadactually broken?NOCCheckif:(1) bobbin out & reloador(2) if sensor is working/properly threadedYESKeep Hook Area CleanOver time, lint, bits of thread and other debris oilcombinebi iin ththe rotarythhookk area tto coatt iimportantt tsewing surfaces and interfere with sewing. Cleanthis area from time to time (more if you run yourmachine hard) with compressed air and/or a spraycleaner such as Hook Wash.If the thread is actually broken, then:Check Thread Feed/Path:- thread path: is it correct at all points?- feed: is it smooth? Is it catching on anything?- Correct Needle orientation? Scarf should be at back.If path/feed is not the cause, then:Check condition/quality of thread:Old or mis-handled thread will break more frequently,especially when running in significant volume/speed.Use quality 40-wt polyester or rayon embroidery thread.If the bad thread is not the cause, then:Maybe a design problem if breaks in the same place(s).1. Turn on the Stitch Sweeper, and reload the design, or2. Have the digitizer fix the bad section or run a designcleanup to remove short stitches.If the design is not the cause, then:Check for damage/scarred surfaces from hoop strikeor needle break. Broken bits of needle/other metal mayscar/bur surfaces that contact thread i.e. needle, presserfoot, needle plate, point area of rotary hook. Replaceneedle, use fine abrasive cord/cloth to “polish” thesesurfaces smooth again.Chapter 4: Troubleshooting & MaintenanceRe-threadand sewagain.Improper Thread TensionOOver-tightti ht AND over-looselttensioni eitherith att ththebobbin or the upper thread contribute indirectly tothread breaks.Rotary Hook TimingIf you’ve eliminated the most common causes,check to see if the rotary hook may have slippedslightly out of time. Read more on rotary hooktiming, its significance, how to check and adjustlater on in this chapter.3

Education DepartmentTraining Workbook: HAPPY HCS-1201 Voyager Operations and MaintenanceGeneral Maintenance and Upkeeppp Oiling: Use only white sewing machine oilThere are 2 oiling schedules based on how frequently themachine is used:- Every 8 hours (or more if used heavily) – 1 drop of oil onthe “race” of the hook as shown.- Every 40 hours (as shown in diagram below, right)(a) needle bars: 1 drop on each(for b, c, and d, move head to Needle 1)(b) “cup” cut-out marked in yellow on machine( ) reciprocator(c)it andd presser footf t shafts,h ftupper portiona(d) reciprocator and presser foot shafts,lower portion“race” of the hookbc CleaningdClean the rotary hook area on a regular basis(especially with regular use) using solvent andcompressed air. Helps prevent buildup of debris/oily filmfrom lint/dust and oil spray. Reduces thread breaks &other sewing problems. Remove theneedle plate first to getbetter accessfor cleaning.Removing the needle plate exposesmore of the rotary hook area formore-thorough cleaning.Chapter 4: Troubleshooting & Maintenance4

Education DepartmentTraining Workbook: HAPPY HCS-1201 Voyager Operations and MaintenanceAdvanced Maintenance/Repair:pHook TiminggRotary Hook TimingThe rotary hook is responsible for catching the top thread and creating a loop around thebobbin thread in order to form a stitch. To catch the top thread, the point of the rotary hookmust arrive at a precise moment and distance to the needle (timing and clearance). Whenthe timing and clearance are out of adjustment, the machine will generally experiencemissed stitches, looping, thread breaks and needle breaks.Checking Rotary Hook Timing and ClearanceIf you suspect that your rotary hook timing is off, you or your customer can check this easilyyourself following these steps:1. Power the machine on and allow it to continue to the main drive screen.2. Select needle six (6). Do this using thekeys on the control panel3. Remove the needle plate and bobbin case . Do this by loosening each of the two (2) flatheadscrews with an offset screwdriver (provided in the machine’s toolkit)Timing for HCS-1201is at 25 degrees.degrees3. Remove the bobbin case.4. Engage the needle. Do this by pressing the P.FOOT key, which lowers thepresser foot. Then, grab the needle bar over the presser foot, and pull it downuntil it locks into place.5. Turn shaft to 25 degrees. Do this with a 3mm Allen wrench. Turn the main shaftfrom the rear of the machine clockwise to L 25 (25 degrees). The needle shouldbe down and in the basket area of the rotary hook at this point.Chapter 4: Troubleshooting & MaintenanceWith the needleengaged,d it shouldh ld fallf llinto this basket in frontof the rotary hook andjust behind the retainingfinger.5

If the pointis either touching or too far from the needle, the machine isnot set correctly and will require adjustment.Note that the hook pointpasses behind the needleacross the lower portionof the scarf.This clearanceshould be aboutthe width of abusiness card.Chapter 4: Troubleshooting & Maintenance6

Education DepartmentTraining Workbook: HAPPY HCS-1201 Voyager Operations and MaintenanceAdvanced Maintenance/Repair:pHook TiminggAdjusting Rotary Hook Timing1. Loosen the Rotary Hook. Do this by loosening each of the three (3) set screwsthat attach the rotary hook to the rotary hook shaft. Start with the larger screw on themilled flat spot of the hook’shook s neck (lower right).right) Loosen screws just enough tobreak the hook loose on the shaft. Turn the wheel as necessary to access eachscrew from either side.(3/4 view) 3 set screws are locatedalong the rear “collar” of the rotaryhook.3. Reset the dial to 25 degrees. Check that the needle is lowered into the rotary hookbasket once more and that the main shaft dial is set 25 degrees. Adjust the mainshaft as necessary by hand at rear of the machinemachine.4. Move hook and tighten screws. Adjust the timing and clearance simultaneouslyaccording to the diagrams on the previous page. Tighten screws carefully. If necessary,have an assistant hold the main shaft exactly at 25 degrees while positioning andtightening.Helpful Hints- Have a helper hold the timing wheel at 25 degrees with the T-handle wrench asyou make your adjustments and tighten the screws.(side view) Turn the hook as necessaryfor easy access with a screwadriver.- Tighten each screw just enough to snug the hook back on the shaft, then re-checkre checkthe timing, then tighten each screw further. Tighten all screws as firmly as you canmanage. When practicing, re-check constantly as each screw is tightened.- Use a quality flat-tip screwdriver with a wide grip to help you apply enough torqueto secure the rotary hook tightly on the shaft.Loosenoose thiss scscrewewfirst before theother 2.Chapter 4: Troubleshooting & Maintenance7

Education DepartmentTraining Workbook: HAPPY HCS-1201 Voyager Operations and MaintenanceMechanical Procedures: Hook Retainer AdjustmentjStub of hookretainerAbout the Hook Retainer (also called retaining finger)The hook retainer is located at the front of the rotary hook, near thetop of the bobbin case. It is responsible for keeping the inner basketand bobbin case from spinning freelyfreely, while still allowing thread topass across the front of the rotary hook.Adjusting the Hook RetainerFollow this short procedure to adjust the hook retainer:Hook retainer orretaining finger1 Remove the needle plate.1.plate Do this by loosening each ofthe two (2) flathead screws with an offset screwdriver.2.
