Eliminate the knock
The adjuster always knows how to get rid of the knocking. Seamstresses often encounter such a problem when working on the machine “Podolsk”. To do this, pull the flywheel in the axial direction from the machine. In most cases, the trick helps. Sometimes you have to disassemble the device. Requires unscrewing the limiter in the form of a screw under the drive. Remove the handwheel. As well as the bobbin and bushing. The master puts on a washer, which he can make himself. This trick helps get rid of knocking for a long time.
Next, let’s look at the basic adjustments of the machine to get quality stitches. Let’s start with the most basic settings, and then explore possible problems at the end.
Stitch type, length and width
Despite the simplicity, the adjustment of these values can affect the quality of the finished product. For different materials and tasks, the machine manufacturer has provided special stitches (knitwear, blindstitch, edge stitching) with specific recommended length and width. Even straight stitches cannot be the same for thin and thick fabrics. The thinner the fabric, the shorter the stitch length should be set, but on a thick coat fabric or leather stitch should be 3-4 mm.
The width of the zigzag should also be set according to the type of fabric and task. A wide stitch can pull down on thin fabric, and a narrow zigzag stitch will not cut a seam allowance in a loose, thick material.
Select special needles and threads for each fabric, as well as the optimal balance of stitch length and width. Always test a stitch on a scrap of the same fabric before starting.
Thread tension
The sewing machine stitch should be set so that the top and bottom thread weave knot is inside the fabric, and will not be visible from the front or the wrong side. If the adjustment of thread tension in the machine is mechanical, then for the upper thread on the body will be a special regulator.
On the test stitch, check to see if the weave knot is visible:
- if the knot is visible from the front side of the fabric, it means that the upper thread is too tight;
- a knot on the wrong side indicates low tension of the upper thread.
The bobbin thread tension is changed with a special screw on the hook and this knot should only be used as a last resort when changes to the upper thread do not produce the desired result. On machines with a vertical hook, check how easily the thread pulls out of the cap. To do this, take the tip of the thread tucked into the cap of the bobbin and lift the entire device up. Ideally, the hook cap hanging from the thread should go down 2-3 cm. If it does not respond to hanging, the tension is excessive, and if it descends quickly, the tension is weak. To adjust, use a special screwdriver to tighten the small screw on the side of the cap, no more than half a turn.
In machines with a horizontal hook, the tension is controlled by a screw on the hook, which can vary from machine to machine. Sometimes it may be necessary to remove the needle plate. If the screw is closed with a seal, it means that the manufacturer does not provide the possibility of such an adjustment and unlocking this place will void the warranty of the machine.
There are also modern models on the market with automatic tensioning and electronic controls.
Setting the presser foot pressure
Some machines have manual presser foot pressure adjustment, which is used when sewing thick and thin fabrics. Pressure is increased for thick fabrics and decreased for thin fabrics. The tension is adjusted by turning the screw, which is usually located on top of the machine or by the regulator on the left side of the machine.
Some modern machines offer automatic or electronic foot pressure adjustment.
Setting up a sewing machine for today’s models
No matter what kind of machine you have. Our tips on how to set up your sewing machine are universal and will work for Brother and other well-known manufacturers.
Stitch settings
Even the budget model has a sufficient choice of stitches, allowing you to sew with different techniques. In many ways, how to adjust the stitch on the sewing machine determines the choice of fabric. You can select the stitch parameters manually. Then the stitch will come out a quality stitch.
Note, for delicate materials, you need to adjust the stitch on the sewing machine so that the step is shorter.
The instruction manual for Brother, for example, has a detailed description of the stitches with tasks and fabric type, so setting up the sewing machine yourself won’t be difficult. For some fabrics and modes, it will be necessary to change the stitch width and needle.
Installing the needle in the sewing machine
Installing a needle in a sewing machine
Seen inexperienced seamstresses with uneven or skipped stitches? This means that the machine’s needle to hook is out of alignment. Especially important is the correct setting of the needle if you sew with a zigzag stitch.
The needle going up 1.8 mm to meet the hook. Adjust the desired position with a wrench, open the fastener a little, fixing the wheel.
If you suddenly can not use a double needle on the sewing machine, call the master.
Adjusting the needle bar and tensioner
Adjusting the sewing machine needle bar and tensioner
There is often a problem with the thread. It can tear at the most inopportune moment, sag excessively or be constantly in motion, which interferes with work. In this case, the stitching is uneven or skipped. The tensioner will help correct this. If it is not monitored at all, it may even move or fall out. And then the needle bar is at the top with the needle.
You need to loosen the screw and place the needle so that the groove is in the correct plane.
Setting the tension of the work thread and the lower thread
Setting the sewing machine thread tension
How you adjust the sewing machine thread tension will produce that stitch. Ideally, it will be smooth, without tension and loose stitches. If you see that the upper thread is too tight, you need to set the regulator on the machine to a lower number. Do it carefully. Try moving the adjuster slightly and then stitching to see the result. If you are still not happy with it, turn the regulator some more.
The half stitch at the bottom should not go up. If nothing changes from adjusting the upper thread, try adjusting the lower thread.
The hook will help you adjust the lower thread tension of your sewing machine. If the bobbin in it does not move in any way when you hang the hook on the thread, you need to loosen the tension. And when the bobbin moves too much. reinforce.
To make the tension more, clamp the key with the screw, moving clockwise. And if you want, on the contrary, to reduce it. counterclockwise. And better, after each rotation of the adjustment check the result with new stitches.
Adjusting the position of the bar
Adjusting the position of the bar
The toothed bar affects how the fabric will move during operation. When the needle goes through the fabric, the tooth should be level with the table. Otherwise, when you use the sewing machine, the fabric will lie still or pull hard, tear. The stitching will also be very bad.
Adjusting the position of the bar is easy. Raise the presser foot and move the bar to the correct position by moving the handwheel closer to yourself. How to do this, even better described in the manual.
Sewing machine foot adjustments
How hard you press the foot, depends on the quality of the stitching and your comfortable sewing. If the machine is quite simple in its construction, the sewing foot is easy to use, you need to adjust it with a screw on the holder. In modern models, the screw is on the body. And you need to adjust it depending on the instructions.
Pedal tuning
Adjusting the sewing machine pedal
If you have an electric drive, problems with the pedal may be due to the drive itself. For example, when you use a Janome sewing machine, there is a speed regulator in the pedal. And if it fails, the pedal behaves unusually.
This can be solved as follows. When you act on the lever, the tablets fold into one, the resistance goes away, and the speed increases. You have to take the pedal apart, clean it and put it back. But if that doesn’t help, you have to buy a new speed controller.
How to adjust the sewing machine
Synchronization of sewing machine parts and mechanisms is very important. Although the overall setup process is basically the same for most types of sewing machines, but the method of disassembly and assembly of parts is different for each machine. so be sure to refer to your machine’s instruction manual, as you will need to go through the steps of checking and fine-tuning. And before you begin the repair process, you still need to decide whether it is wise to start the repair yourself, or turn to specialists who make quality repair of sewing machines.
Needle Alignment for Brother CS-6000i
Part 1 Diagnosing the problem
Be sure to check for other potential problems, other factors that may be causing problems in the normal operation of the machine, because there is no point in taking the machine apart if it doesn’t need to! Make sure that the sewing needle is not bent and that it is fully inserted and firmly secured with the screw. Make sure that the needle size, thread type, and fabric type are compatible. Heavier fabric requires a larger needle size and thicker thread.
Check synchronization errors, because by checking the needle and hook position, you can determine whether your machine needs a synchronization adjustment. To do this, leave the needle in place and remove the bottom cover and the bobbin. Turn the handwheel slowly to make sure that the hook of the hook picks up the thread smoothly. If this does not happen, you may have to adjust the mechanism. Use a ruler to measure the timing settings. Use the handwheel to put the needle at its lowest point and then raise it 2.4 mm. The axis of movement of the hook should be directly above the needle hole. If it is not, you may have to adjust the timing of the machine.
If you determine that you need to adjust the timing, make sure that the machine is ready for it. It may be necessary to switch the stitch position to straight stitch, ensuring that the needle is lowered through the center position. Remove the cover over the hook, switch knobs, bobbin, and allow access to the base of the machine. Gather the tools you may need, such as a large and small screwdriver, an oil can with appropriate oil, and provide the workplace with good lighting. At this point, you should think again about turning to a sewing machine repairman, especially since he has an inexpensive overlock repair.
Part 2 Adjustment and tuning
Set needle clamp height. Most machines have markings that indicate the proper height to properly adjust that position. Refer to the manual for instructions on how to access the needle clamp adjustment. If time stamps are present, loosen the needle clamp and move it up or down to align the top mark. If there are no marks, lower the needle all the way down with the handwheel, then raise it 2.4 mm. Adjust the height of the needle so that the needle hole, was located at 2.4 mm below the tip of the hook.
Setting the gap between the shuttle and needle. The adjustment of this position varies depending on the manufacturer and model. However, there is a general approach, to adjust the distance between the hook and needle.
Using the handwheel, lower the needle bar to its lowest position. Loosen the hook assembly at the base of the machine. Change the clearance from hook to needle, which should not be less than 0.04 0.1 mm depending on the model of machine.
Check the accuracy of the settings. When you retest the needle and hook positions, you can tell if your settings have improved the sewing machine’s performance. If you have removed the thread from the needle, rethread it. Slowly turn the handwheel to check that the hook of the hook catches the thread smoothly. If the hook catches the thread every time, your time has been well spent.
Part 3 Assembly and testing of the machine
Reassemble your sewing machine. Carefully tighten all screws and make sure there are no excess parts and screws/bolts/nuts.
Clean any dirt and dust and oil any exposed gears. Refer to manual to find specific items that definitely need lubrication. Use only the recommended brand of oil for sewing machine lubrication.
Install covers and switch knobs.
Check the results of the repair. Re-thread your machine and sew a test piece of fabric. Stitches should be of good quality, with no puffs, missed stitches, or broken needle.
If the problem persists, you may still need to contact a shop that also repairs your Brother sewing machine.
Purpose
There is a persistent misconception that you only need to sew with a double needle on a sewing machine when you need to get two parallel stitches. In fact, the “possibilities” of the dual device are much wider. It is used when necessary:
- To hem a sleeve or the bottom of a knitted garment;
- Lay decorative stitching;
- To make a measure;
- Sew on a braid;
- Form embossed guards.
For sewing lace and shaping pins, you will also need to purchase special feet.
Please note. These stitches are designed for decorating and undercasting, not for sewing over individual patterns.

The Brother manual, for example, has a detailed description of the stitches with tasks and types of fabric, so setting up the sewing machine yourself will not be difficult. For some fabrics and modes will need to change the stitch width and needle.
Installing the needle in the sewing machine
Seen inexperienced seamstresses with uneven or skipped stitches? This means that the machine has not adjusted the needle to the hook. It is especially important to put the needle correctly if you sew with a zigzag.
The needle should be 1.8 mm higher and meet the hook. Adjust the desired position with a wrench, open the fastener slightly, fixing the wheel.
If you suddenly can not use the double needle on the sewing machine, call the master.
Adjusting the needle bar and tensioner
There is often a problem with the thread. It can tear at the most inopportune moments, excessively slack or constantly be in motion, which interferes with work.
In this case, the stitching is uneven or with gaps in the stitching. Use the tension adjuster to correct this.
If it is not followed at all, it may even move or fall out. And then the needle bar is up with the needle.
How To Change The Needle Position on a Brother Sewing Machine
You need to loosen the screw and place the needle so that the groove is in the correct plane.
Adjusting the working thread tension and the bobbin thread tension
How you adjust the sewing machine thread tension, that’s how the stitch will turn out. Ideally, it will be smooth, without any tension or loose stitches. If you see that the upper thread is too tight, you need to set the regulator on the machine to a lower number. Do it carefully. Try moving the adjuster slightly, then do a stitch to see the result. If you are still not happy with it, turn the dial again.
The half bobbin thread from the bottom should not go up. If nothing changes by adjusting the upper thread, try adjusting the lower thread.
To adjust the tension of the lower thread sewing machine will help shuttle. If the bobbin does not move when you hang the hook on the thread, you need to loosen the tension. And when the bobbin moves too much. reinforce.
To get more tension, tighten the wrench with the screw moving clockwise. And if you want to decrease it, on the contrary. counterclockwise. And it is better, after each turn, check the result of the adjustment with new stitches.
Adjusting the position of the bar
Toothed bar affects how the fabric will move during operation. When the needle goes through the fabric, the tooth should be level with the table.
Otherwise, when you use the sewing machine, the fabric will lie still or pull hard, tear.
The stitching will also be bad.
It’s easy to adjust the position of the bar. Raise the presser foot, and move the bar to the correct position by moving the flywheel closer to yourself. How to do this, even better described in the manual.
Adjusting the foot in the sewing machine
How hard the foot is pressed affects the quality of the stitching and your comfortable sewing.
If the machine is fairly simple in its construction, the sewing foot to use easy, you need to adjust it with a screw on the holder.
On modern models, the screw is on the housing. And you have to adjust it depending on the manual.
Pedal Adjustment
If you have an electric drive, problems with the pedal may be due to the drive itself. For example, when you use a Janome sewing machine, there is a speed regulator in the pedal. And if it fails, the pedal behaves unusually.
You can solve that by doing the following. When you act on the lever, the pills fold into one, the resistance goes away, and the speed goes up. You need to take the pedal apart, clean it, and put it back in place. But if that doesn’t help, you have to buy a new pedal.
Adjusting the interaction of the needle and shuttle sewing machine
The quality of the result during sewing depends on the adjustment of the hook and needle assembly, or rather on the correspondence of the gaps between them to the correct values, and if not, it can also lead to skips, loops and breaks in the lower and upper threads. In order to be able to make this adjustment, you must understand how the machine works for looping.
Thus, when the needle is raised by 1.5-2 mm from its original position, a loop is formed from the upper thread, located slightly above the eye. In doing so, the hook’s spout should pass almost flush to the needle’s groove. This distance should not exceed 0.15 mm. The distance from the hook nose to the eye of the needle in this case should be 0.5 mm. These values are approximate and correspond to medium-thick fabrics. Depending on the type of fabric used, these may vary slightly. To know their numerical value can only be determined experimentally when working, and in most cases this skill comes with experience.
It is also worth noting the importance of the vertical position of the toothed rack. They are responsible for moving the fabric in relation to the needle and the sewing machine body in the process of work. At the moment when the needle pierces the fabric, the upper edges of the slat teeth should be at the level of the sewing machine table.
Breakdown Causes
Adjustment of sewing machines should only take place after finding out the cause of the breakdown. Craftsmen identify several major malfunctions:
- Thread breaks along the seam after sewing. It occurs due to a dull needle;
- Stitches are skipped because the needle type does not match the threads;
- Damaged fabric due to improper material selection and needle number;
- there is no top stitch due to the wrong position of the bulb;
- The needle breaks if it is bent or installed incorrectly.
Important! Masters often notice needle breakage in Artista machines.

Operating Instructions
The instructions for the sewing machine are not much different from the instructions for other portable devices and involve an explanation of the settings of the machine and the rules of its use. Before direct work, it is worth carefully setting up the machine.
How to adjust the sewing machine brother
To turn the machine on before setting it up, proceed as follows:
- Prepare the power cord for the machine;
- Check that the sewing machine is off by looking closely at the switch;
- Insert the cable with the power connector into the socket on the right side of the machine;
- Insert the cable plug into the mains;
- Press the switch and set it to the “on” position.
Important! Once the mains power is on, the light on the switch will turn on, indicating that you are ready to start sewing.
After one has figured out how to turn it on, there are a few more things to do:
- Winding the bobbin. To do this, the thread is wound onto the bobbin with the machine on. The bobbin is placed on the shaft, which slides to the right until it clicks. The spool pin turns upwards and takes over the spool of thread. After refilling, the shaft is moved back to its original position;
- Installing the bobbin. Press button “1”. raising and lowering the needle to raise the needle and raise the presser foot lever yourself. Turn the machine off and remove the hook cover. Insert the bobbin so that the thread winds to the left and pull the thread under the tab. Replace the hook cover;
- Threading the upper thread. Install the spool of upper thread and then thread the needle. You need to turn on the machine, raise the presser foot, raise the needle with the appropriate button, turn the spool pin and remove the cap from it, set the spool of thread on the pin. Next, the thread is simply guided under the thread guide and threaded into the machine according to the pattern shown on the machine;
- Threading the needle. It all depends on whether you have a model: with or without the thread guide disk. In the first case, everything is automated, while in the second. you will have to do the process yourself: tuck the thread, put the thread through the eye of the needle from the front back and pull the thread through the presser foot after it is lifted.
Important! After these adjustments have been made, you can start to work and avoid malfunctions. Additional items in each individual machine’s usage guide involve explaining how to use the twin needle, changing the needle, changing the presser foot, and so on.
How to use a brother sewing machine
The following instructions will show you how to use your Brother machine correctly:
- Place the machine on the work table, which should be stable and firm. It is recommended to use special stands;
- Insert the needle securely into the machine with the flat side back to lock it in place, and tighten the screw that holds it in place;
- Position the spool. As already understood from the instructions, these machines use two sources of thread: the lower and the upper;
- Insert the thread into the machine. Unwind the thread from the top and thread the needle;
- Take out both threads. This is done by swiping a flat object under the foot and releasing both ends;
- Plug the machine’s power supply into the home power supply and turn it on with the appropriate button;
- Choose a stitch type and size and practice on unwanted material. This will help you understand the machine and build up your hand;
