Dear Industrial sewing machine operators,
My friend bought this sewing machine and I can't find a manual or any information on how to thread it properly and make it work. I do not believe it is broken at this point. I think I don't know how to operate it properly.
Can you help?
vgibson @vix.ca
I have the manual in pdf form here
http://myweb.tiscali.co.uk/stitches/BROTHER-DB2-B755-MKIII-MANUAL.pdf
Seems this industrial machine is branded with several well known makes. I have purchased the machine direct with the manufacturerTamata and the model is a PF8500 which is branded as a Brother SL7553A or Brother DB2-B755 - Also known as Wimsew High Speed Lockstitch Industrial sewing machine.
Re: query by hawthornhedg Please please could I have the pdf? I have had my machine serviced (at great cost) and know that it works OK but find it far too fast for normal sewing jobs and wonder if there is a way of slowing it down by adjusting the pedal. Hello, I know that this thread -and your question- is tad dated, but since nobody answered I decided to post my explanations. Besides, those are rather "universal" issues, so others might benefit from my advices as well. About the manual: The manual, as a pdf file is available, surprise surprise ;-) on... brother-usa.com website: http://www.brother-usa.com/ModelDocuments/Consumer/Instruction%20Manual/IM_DB2_B755_EN_5013.PDF It is NOT the same manual that was available here - it is kinda abbridged, multi-lingual version - but it still contains all the info about various adjustments and user-serviceable parts. Abridging in this case means getting rid of all that superfuous "safety precautions", like "don't drink the lubricating oil", "don't sew through your fingers with dirty needles" - and other such pieces of wisdom. If one cannot live without abovementioned knowledge and sophistication, please do visit this page in few days time - I just exchanged few emails with the user mikerbot, to whom I just sent that "bigger" manual - and he's going to upload it on some filesharing service and post the link to it here.
About the "slowing down the machine" (and "regulating the pedal"):
The "pedal" only operates the clutch - providing you've got a standard, flywheel-and-clutch sewing machine motor on your Brother (or Yuki, or Whatnot Brand), either single- or triple phase (doesn't really matter which).
In this case the clutch (pedal-operated) is not really meant to "regulate" the speed (the "top speed", at least), but to provide soft ("smooth") start for the machine - and TEMPORARY only "speed adjustments". (You can use it for that purpose, for example, when starting or stopping making a seam, or when doing some "small and precise jobs".)
But the clutch is just that - a clutch - a single disc, "dry" friction clutch (seehttp://en.wikipedia.org/wiki/Clutch)
Perhaps (I guess so) by "too fast" you meant that the machine starts too suddenly ("jerks") when clutch pedal is depressed - in that case the problem is not really with a "regulation", but -most likely- with too dry disc friction facing (a.k.a. clutch pads).
Although technically it is a "dry" clutch (i.e., not immersed in oil) it still should be greased with a solid grease "every now and then" (preferably, a graphite grease - although plain, regular industrial grease would also do).
Typically, the disk friction facing is made of cork, and it slowly wears off during normal machine use. (Some manufacturers, like then-East German or Chechoslovak ones used formaldehyde resin pads, which are to be used REALLY dry - no grease at all - and are nearly service-free and could last almost a lifetime - but, AFAIK, MOST manufacturers use cork pads.)
Apart from regulating the free play of the clutch, one also has (which is even more important!) to apply periodically some grease on the cork pads.
To do so one has to take apart the clutch-motor assembly (see your MOTOR owner manual; although it should be pretty simple job - a screwdriver or flat spanner, or a hex key, and three screws plus two able hands).
Once the clutch is dismantled, spread a thin layer of a grease on the cork pads (preferably leave it overnight in warm place to let the grease "soak" into the cork), then wipe off excess of the grease and reassembly back the clutch and the "proper" motor.
How often this procedure should be repeated? As often as needed, depending on the use of the machine - for "normal, small workshop use" one good greasing should last for at least couple of months, maybe up to a year, depending on the "style of the operator" and quality of the grease used (that's why graphite grease is recommended - graphite binds to the metal face of the flywheel and makes the whole things work smoother for longer time).Â
Also, some sewing machine motors have two (or more) points on the clutch lever, where a thin rod (or chain) connecting the lever to the pedal can be attached to - in that case try moving the rod (or chain) to the point closer to the "free" end of the lever.
This will make the clutching action smoother, but it may require additional adjustment of free play of the clutch.
If this solves your problem then you're set. If not, and the real problem is the top speed itself, then the solution is going to be more expensive and/ or more complicated.
If you want to "slow down the machine" altogether, you can either slow down the motor itself, or increase the V-belt transmission ratio (i.e. relation of diameters of V-belt wheels on the motor and the machine).
To slow down the motor, the best (?) and simplest way would be to use some electronic device, like VFD (Variable Frequency Drive,http://en.wikipedia.org/wiki/Variable-fr...
Sorry, no idea how these thingies cost - check the power rating or amperage of your motor, and then find "right" VDF device ("right" means ot the same of greater power/ amperage rating, single- or triple phase, depending on your motor).
To slow down the machine "mechanically" one has to change the relative diameters of the V-belt transmission - either to put smaller V-belt wheel on the motor ("driving wheel"), or a bigger wheel on the machine ("receiving" or "driven wheel").
The first is simpler in theory, but motors typically have already rather small driving wheels - so there isn't much room to adjust the ratio.
Some motors have DOUBLE V-belt wheels (i.e. with two "groves" for belt, with different diameters) on the "power output" shaft - in that case is is a snap: one nas to move V-belt to the smaller wheel (and adjust the tension of the belt, of course).
sorry, something is, uh, broken on FixYa website - I can't add the last part of the solution - pls email me directly if you want to know it

Please please could I have the pdf? I have had my machine serviced (at great cost) and know that it works OK but find it far too fast for normal sewing jobs and wonder if there is a way of slowing it down by adjusting the pedal. I remember seeing someone using the machine to repair harness once but can't imagine how they controlled it.
