Pre-service Trial

Our certified technicians prefer to compare the state of your sewing machine before and after maintenance. Therefore, as soon as they get their hands on your Viking Husqvarna sewing unit, they check the machine for any startup or power troubles and then run a series of stitches.

This allows them to get a good assessment of the current state of your sewing machine. They note down any visible issues and keep them for later comparisons.

Outer Survey

Once they are done with the Pre-service trial, they inspect the external body of your sewing machine. Parts such as the needle plate, hook, bobbin, spool pin, and head wheel are examined for any damages.

Our techs also check for burrs because burrs can cause damage to the thread and also influence the thread tension in the system.

Stress Inspection

Next up is a stress test on both the top and bottom threads. Thread needs to be distributed perfectly with the right amount of tension for the machine to perform as expected.

Any faults in the stress discs or the overall spring tension retention on the machine will cause overlapping stitches and other issues. So we evaluate the stress by moving along the top thread and also making sure that it passes through every mechanism it needs to.

Once we are done inspecting the top thread, we move onto the bottom thread and the bobbin winder. Here we check the bobbin tension along with its speed.

A bobbin needs to feed the bottom thread fast enough to create evenly spaced stitches and have the right amount of tension to avoid loose stitches. If we find any issues here, we make the adjustments and modifications to get it back on track.

Feed Dog Check

The Feed dog plays an important role in getting your stitches right. It feeds the product into the sewing machine on time so that the stitches created are evenly spaced.

Any issue with your feed dog will cause uneven or, even worse, overlapping stitches. None of us are too keen on wasting time removing stitches and ruining the fabric.

So, we test every feature of your feeding mechanism. Generally, a feed dog comprises two feed teeth.

The feed teeth of a Viking Husqvarna sewing machine usually move forward and in reverse and some models even let you elevate and lower them for free handwork. When examining the feed teeth we will check if the feed teeth move in every direction possible and also that the special movement works fine.

Issues With Extra Features

Our techs pay attention to any additional features your sewing machine may offer. Many recent sewing machines come with an inbuilt needle threader. It’s quite useful for anyone having trouble getting the thread into the eye of a needle.

Our specialist will examine the mechanism and do the adjustments needed for proper functioning. If the needle threader cable is damaged beyond repair, they might suggest a replacement. Another handy feature in modern sewing machines is the Automatic Button Holer. Our techs will inspect its functioning as well.

Along with the inspection of extra features, our techs test out your firmware if you’ve got an electronic sewing unit. And if it requires an update, they’ll have it installed by the time the machine is handed back to you.

A Look Inside

Once the outside of your Viking Husqvarna sewing machine is taken care of, we take a look inside. We remove the covers and give the internal chassis a thorough cleaning. The dust and dirt are taken care of while old oil or lubricant is replaced. We make sure that every crevice, even the ones that are hard to reach, is dust/dirt-free.

The oil change of the machine is done with extreme care because we don’t want oil seeping into areas that do not need it. This will do more harm than good.

Once the internal cleaning session is over, we examine the stitching operation and the timing of your machine. A sewing machine uses both the top and bottom thread to form a stitch. It does this by grabbing hold of the top thread when the “top thread” fastened needle punctures the product.

A hook called the shuttle hook grabs hold of the top thread and creates the stitch after a 360 rotation. The needle puncturing the fabric, the shuttle hook grabbing the top thread, and the hook resetting should all be done at the perfect time to create a stitch.

A delay in any of these actions will cause an issue with the stitches. So, we make all the adjustments to get the timing right, including. We also deal with any feed timing issue here.

Post-service Trial

After all the internal problems are taken care of, our techs put the covers back on and give it a nice wipe. They use 100% natural cleaner so that it doesn’t harm the exterior. Our certified specialists then conduct a few tests to assess the current state of the machine.

First, they test out various stitch types like straight stitches, Zig-Zag stitches, and Reverse stitches. They then run the machine at its highest sewing speed to assess the internal workings.

Finally, our technicians go through every additional feature your sewing machine offers to make sure that they are working fine.

There’s way more technical stuff happening on the benches of our professionals, and this is just a peek at it. Nevertheless, we are pretty proud of our sewing machine repair process and got plenty of reviews to back up its success. So, if you are having sewing machine troubles, join us and we’ll solve them all for you!
