Insight From The Work Bench

Recently I taught a repair class on the Husqvarna Viking Diamond sewing machine in Portsmouth, New Hampshire. A special thank you to Mary from Merri's Stitches for inviting me to teach my class.

With the 2018 VDTA Show being in my home town of Charlotte, I have scheduled the same Husqvarna Viking Diamond repair class for March 21, 22, and 23. The VDTA Trade Show is open from the 24 – 26. The fee for the 3-day class is $750 per person. The class will have a 10-person limit, and each class will be approximately 8 hours long. Once you understand the Diamond design completely, you will also fully understand every model below the Diamond that shares the same frame. My class will be at a local hotel here in Charlotte to be announced closer to the class date.

In this class, we remove both the hook and feeding system, and service them both to eliminate any binding. We then free up the rest of the machine so the drive motor runs with the smallest load possible. Once I show where the binding occurs and how to remove it, you will immediately feel it in the hand wheel.

We next separate the top of the machine from the bottom of the machine to understand the load differences, and for a feeling of what normal load is. We examine needle bar play and address how to identify where it is and how to fix it.

Then we cover how to get the pre-tension value to register proper resistance plus motor belt tracking issues and how to correct them. Of course, we also cover proper techniques of how to reset factory portioning and tension settings with an understanding of how they work with one another so you get perfect stitching. Your machine will also be very quiet in its operation, and you will fully understand why your previous repairs were not.

Once you know where to start the adjustment process, you'll see the machine from a totally new perspective and get the most perfect results for your customers.

Eddie Ryan from Nashua Sew and Vac is a Technician with 40 years of experience who recently took my class in New Hampshire. He and I share the same viewpoint that you
never quit going for training! He emailed me quite a nice letter after our class, expressing his new excitement about what he learned. He also said that when he got home, he attacked an original Diamond in for service, and that after his service, "The machine had never been so quiet and the tension perfect!" He did the same to a Diamond Royale with the tension portioning system and "was so thrilled to finally understand the concept and adjust the machine perfectly."

If you are a Husqvarna Viking dealer and struggle with anything in terms of setting their machines to work perfectly, you need this class. You don't work on this $10,000 sewing machine like you do a $300 machine. You need to spend more time to make it perform like the engineers intended. When I see people complaining on the internet about the Diamond and how they have a lemon, I get slightly irate. There are no lemons, only dealers who don't take the needed time to service it right.

No machine made by man is perfect. Every brand has its own strengths and weaknesses. It is our job as technicians to figure out those weaknesses in the field and correct them, even when the manufacturer doesn't.

When you minimize the mechanical load or "binding" in a top-of-the-line machine, you don't overload the motor's operation or "electrical draw" through the main PC board. When your customers sew a 45-minute embroidery and their motor has the slightest additional load, it compromises other electrical functions of the machine. Strange things occur, and inexperienced techs just start swapping boards like throwing darts. They are the ones you read about on the internet, the ones whose customers blame Husqvarna for a bad design when the real blame should be placed elsewhere.

I don't see a lot of the machine problems that other dealers complain about and haven't for years. I figured out that with my approach to service, I stop a lot of problems from developing.

I'm looking for top technicians who want to be better. You can sign up for my class by calling my store at: 704-541-1303; full payment reserves your spot.

My last class also had two ladies who were brand new to service. They both were great with handling all the new information, and I look forward to helping them on the phone in the future. So when I say I'm looking for top technicians, I'm looking for people with the right viewpoint, who don't blame the customer first, & won't quit until their repairs sew with the best stitch possible.
