My machine has been out of commission for a month now because I hit the hoop with needle number 2. This is the second repairman that adjusted my hook timing without straightening presser foot first on my needle number 2. Consequently, needle number 2 is still looping, skipping stitches, etc. I am so upset. Why don't these repairmen read your note? I had to leave my machine there again. What can I do? I am so worried that they are going to charge me more money now. All they did was clean it, and adjust the hook timing on the 4 needles. $189. I feel like that's outrageous. I haven't paid them yet since it is still broken and at their shop. The first repairman from a different shop actually ruined my timing on needles 1, 3 and 4 and then kept my $30 bench fee. How are these Janome Service Dealers able to get away with this?? Please help.
Re: Repairman adjusting hook timing with first straightening pre
If your needles are inserted incorrectly, needle hole not centered DEAD-ON, turned the slightest, or in backwards, etc. it will cause issues that you described. So will burrs on a pressor foot that was bent when you hit hoop if your needle pierced the pressor foot, as your thread spools down through the tensioners/guide above needle the thread maybe coming in contact with burr on pressor foot.
If that isn't the issue, then:
Perform a Tension Test, make sure it's threaded correctly through all tensioners and guides and that the bobbin case is clean and thread spools out correctly and lastly, check to make sure the thread is spooling off Cones through Thread Tree smoothly, not getting caught on anything as it flows.
Any of the above can also cause the issue you described above.
Please reference your Machine Parts Manual for the Hook area. You will find the Hook is under the Needle Plate area, as far as I am aware, each needle does not have a separate Hook that needs to be timed (Never used your brand of machine, maybe it's unique?).
Also, know hitting a hoop is common for Newbie, expensive way to learn to always make sure your design is centered before sending it to your machine and to always do a frame check with pressor foot UP, just in case. ALWAYS, no matter how much of a hurry you're in or how routine your chore, ALWAYS do a Frame Check.
Know, you can straighten Pressor Foot yourself. Use a screw driver or Hex or whatever is required to remove it, then take a pair of pliers and another pair, needle nose work good and straighten it. To make sure it's straight compare it to another that isn't bent. After you put it back on, lower the needle into center of pressor foot ensuring it's straight. If any burrs on the metal, use fine sand paper or fine nail file if no emory cord to remove any burrs (if you needle pierced the pressor foot).
Know, you'll probably never hit another hoop and you can easily learn to trouble-shoot and maintain your own machine, always post HELP questions when in doubt, you'll probably get helpful responses.
BOL and Happy Embroidering!!!
