Setting up a sewing machine, adjusting components at home

Basic operating rules

Setting up a sewing machine will go without any problems if you familiarize yourself with the basic rules for operating the device and follow them. The exact requirements are described in the instructions for each model. But there are basic recommendations that will help you understand different machines:

• the machine is rotated only in the direction towards itself;
• You cannot “sew” on a machine if there is no fabric under the presser foot;

You need to know the device of the machine

• you cannot pull the fabric while the sewing process is taking place;
• it is necessary to lubricate the mechanisms in a timely manner with the means recommended for use in the instructions;
• It is important to refuel the machine in strict sequence.

Important! Not all machines require lubrication.

Typical sewing machine problems

With proper use and proper maintenance in accordance with the requirements of the instructions, sewing machines can be operated for a long time without breakdowns. Malfunctions that reduce the quality of sewing or lead to complete failure of the unit occur in the following cases:

• use of low quality consumables from unverified manufacturers
• frequent power surges in the electrical network, leading to failure of electronic boards and motors
• violation of the rules for using programs and modes of household appliances
• natural wear of parts during long-term use

The following common problems occur with mechanical components and electronic modules of sewing machines:

Causes of breakdowns

Adjustment of sewing machines should occur only after the cause of the breakdown has been determined. Experts identify several main problems:

• The threads break along the seam after sewing. This is due to a dull needle;
• stitches are skipped due to a mismatch between the needle type and thread;
• the fabric is damaged due to incorrect selection of material and needle number;
• the top line is missing due to the incorrect position of the bulb;
• the needle breaks if it is bent or installed incorrectly.

Important! Craftsmen often notice broken needles in Artista machines.

Technologies for cleaning machine parts

In order to troubleshoot problems in the operation of the product, you should adhere to the technology of cleaning mechanical elements.

• The process of adjusting the sewing machine hook begins with removing the needle plate using a small-section screwdriver.
• Using a hard brush, remove any remaining fluff, glue, or dried oil from the shuttle teeth.
• The machine is turned over on its side, then the shuttle is disassembled.
• The stroke parts, heel, nose and ribs, are subject to careful inspection. If the nose does not have a certain sharpness, it should not be sharpened, because a pointed element will easily rip the fabric. The way out of this situation is to replace the part. The heel should have a rounded shape and a clean surface.
• The ribs of the working element are rubbed with a soft cloth with GOI paste applied to it.
• The swing shuttle pusher is equipped with a leaf spring. The function of the spring is to soften the pressing force and make it smoother. At the same time, the spring causes the sewing thread to break. The thread should pass smoothly, without “clicks,” between the spring and the heel, without wrapping around each of the parts. If the heel and petals of the product are pinched or located at a large distance from each other, you should take the car to a workshop.
• The position of the hook nose is adjusted while bringing the device into a horizontal position to keep the parts within the nest. The mechanical or electrical product switches to a mode suitable for straight stitching, with the needle lowered to the lower working position. When the needle is raised by the handle of the machine by 1.8 mm, the nose approaches the end of the latter by 1.5-1.8 mm.

What parameters can be adjusted

Adjusting a household sewing machine does not take much time. There are few parameters that can be adjusted.

• stitch length;
• reverse;
• presser foot pressure;
• thread tension;
• height of teeth.

Important! The wobbling shuttle of Bernina machines often bends needles and tears threads.

Setting the sewing stitch

Setting up sewing machines is carried out using tools and buttons, screws and knobs located on the device panel. To adjust the stitch, the second adjustment method is sufficient. For the correct stitching, adjust:

• Presser foot pressure. The adjustment is carried out with a bolt that presses the foot. It is located on the arm of the sewing machine. For thick fabrics, the pressure is increased, for thin fabrics, the pressure is weakened.
• Comb height. The position of the teeth is determined visually. When sewing thick material, they protrude more than when working with thin fabric.
• Upper thread tension. Its adjustment is carried out using the adjustment wheel, which is located on the top panel of the device.
• The degree of tension of the lower thread. Adjustable with a screw on the bobbin case spring. The uniformity of tension is checked by pulling the lower thread in the position when the machine is threaded. The thread should stretch freely, without jerking, but with little tension.

Setting up a stitch doesn't take much time and is something every necker should be able to do.

What you need to set up the sewing unit

Setting up a sewing machine often does not require special tools. At home, use a syringe to inject lubricant. And also a screwdriver for tightening the bolts. Parameter adjustment occurs without tools. They may be needed if a breakdown occurs. But in this case, the machine is taken to a specialist who will repair the device.

New models of machines from such lines as Brother are sold complete with all the equipment necessary for setup.

Instructions for winding thread on a bobbin

Setting up machines at home does not require much effort. Any owner of a sewing machine can handle winding thread onto a bobbin.

How to proceed:

1. Place the coil on the vertical pin.
2. Pass the thread through the thread guide.
3. Pull the thread between the tension discs clockwise.
4. Insert the tip into the hole on the bobbin. Place it on the spindle of the winding unit.
5. Press the bobbin and move it to the right.
6. While holding the thread, press the pedal.
7. Make a few turns and trim the end of the thread.
8. Continue winding at speed.
9. Move the bobbin to the left.

Important! When full, the bobbin stops rotating.

Classification of sewing machines by type of control

All sewing machines are divided into three main classes:

• Mechanical;
• Electromechanical;
• Electronic.

We all remember our grandmother’s old “Singer” with a simple hand or foot drive that set the sewing mechanism in motion. Later, the Soviet “Chaika” and “Podolsk” appeared with an electric drive and backlight bulbs. These and similar machines belong to the mechanical class. They are simple and quite reliable, can sew almost any fabric, and are easy to maintain and repair.

On the other hand, mechanical sewing machines are usually equipped with the most primitive swing-type shuttle, which limits the speed of work and increases the noise level. The disadvantages include poor functionality, a small number of stitches produced and exclusively manual settings.

The electromechanical sewing machine has evolved significantly from its predecessor. It is equipped with an electronic unit that controls all functions and settings. The most inexpensive models of electromechanical sewing machines are still equipped with oscillating hooks. The new generation equipment is equipped with two modern types of shuttles: horizontal, which provides high speed and soft movement, and vertical, an almost perfect mechanism that produces perfect stitches.

The productivity of electromechanical machines with modern shuttles is incomparably higher, the noise level is quite comfortable, and the range of possibilities and variety of stitches is incomparably wider. The electronic control unit has a certain set of programs, and also allows you to independently select and save settings for certain operations in memory.

As for the disadvantages of such machines, there are very few of them. Firstly, they are much more expensive than mechanical ones. Secondly, they require a more attentive attitude in terms of maintenance, and in the event of a breakdown, repairs in the workshop will also be expensive.

An electronic sewing machine has even more functionality, and each of them is controlled by a built-in microprocessor. Working on such a machine is as comfortable as possible: you just need to select any of the programs stored in memory and press the appropriate button. Depending on the model, there may be several dozen built-in programs. The tailor does not need to manually adjust the length or width of the stitch, or look for the desired type of stitch in the settings - the machine will do all this for him. The processor controls the stroke of the needle, regulates the speed of work regardless of pressing the pedal, controls the thread tension, etc. Electronic sewing machines are equipped with the most modern shuttles, so their stitch quality is impeccable.

As for the disadvantages of such equipment, first of all, buyers may be put off by the very high prices for cars of this class. Electronic “filling” is very sensitive to failures and voltage drops in the electrical network. Most models are not designed to work with very dense and thick materials. And, of course, the cost of repairs can amount to a very impressive amount.

Eliminating knocking

The service technician always knows how to get rid of knocking. Seamstresses often encounter this problem when working on the Podolsk unit. To do this, pull the flywheel in the axial direction from the machine. In most cases, cunning helps. Sometimes you have to disassemble the device. It is necessary to unscrew the limiter in the form of a screw under the drive. Remove the flywheel. As well as the bobbin and sleeve. The master puts on a washer, which he can make himself. This trick helps get rid of knocking for a long time.

Rules for setting up modern machines

Repair and adjustment of modern sewing machines is different. At home, adjustments are a little different. Included with the new electric model, the buyer receives adjustment wheels for manual adjustment, for example, like with Janome.

A spring is used to press the thread when winding. Then the upper thread is threaded through the eyes, tension regulator, thread puller, staples, and needle. Presser foot pressure is adjusted by a spring.

To prevent adjustment from causing damage, use the instructions for the individual model. Use the tools that came with the machine. Do not use other available means. In case of problems, contact the specialist.

What does a modern sewing machine consist of?

Setting the stitch length and type

The manufacturer has provided different types of stitches for all materials. For knitwear or thick fabrics, lines are selected separately. The purpose of tailoring also influences. Therefore, the length and width are set on the machine.

Important! The thinner the fabric, the shorter the stitch should be.

Sets the width of zigzag and other types of stitches. The types of needles are selected based on these parameters. Each line has a purpose.

In the instructions for the machines, manufacturers indicate the compliance of stitches, material, threads and needles. Therefore, it is not difficult to choose them.

Adjusting the stitch length

Setting the interaction between the needle and the sewing machine hook

The shuttle must interact correctly with the sewing machine needle. The parameter is especially important if a zigzag is performed. The position of the looper nose is set a few millimeters above the eye of the needle.

The nose of the shuttle normally fits closely with the needle. In this case, no gaps are formed. The ratio is adjusted by loosening the screw with a wrench and holding the flywheel with your hand. The needle should drop to its lowest point and meet the hook at a 1.8mm lift.

The sewing unit should be taken to a specialist if interaction cannot be established.

Setting shuttle operating parameters

Attaching the needle bar and tensioner

Often the machine stops working due to the top thread breaking and looping. Gaps occur and lines are uneven. It all depends on how the tension regulator is mounted. The tensioner wobbles or falls out. The needle bar moves upward along with the needle.

To correct the situation, you should loosen the screw and adjust the position. The blades and groove of the needle must be in proper contact. If problems arise, check the interaction of the needle and the shuttle.

Refueling the machine

Adjusting the upper thread tension

Adjusting the tension helps to cope with the problem of uneven and unsightly lines. Most often it is excessive. To reduce the tension of the upper thread, turn the adjuster in the direction of decreasing numerical marks. In this case, they do not rotate the entire division at once. Check the lines periodically. The bottom thread should not show through on the top side. If the adjustment fails, try to correct the lower thread.

Adjusting thread tension

Adjusting the bobbin thread tension

Check the tension of the lower thread using a removable hook. If you hang it by the end of the thread that comes from the bobbin, and at the same time does not unwind it, loosening is required. If there is a strong unwinding of the bobbin, the tension, on the contrary, is weak.

Use a screwdriver to turn the adjusting screw clockwise to increase it. To decrease - counterclockwise. Then a check is carried out. Scroll until the shuttle goes down a few cm. For proper adjustment, test lines are periodically laid.

Threading the bobbin thread

Adjusting the height of the gear bar

The toothed bar affects the movement of the material relative to the machine and the needle. When the needle pierces the fabric, the top of the strip should be level with the work surface. If the height is set incorrectly, sewing may occur in one place or the fabric will tear. Often the lines turn out uneven. The quality of tailoring is falling.

To adjust, you need to lift the presser foot lever and move the bar to its normal position. It is indicated in the instructions. The flywheel is turned towards itself.

Rail height adjustment

Height of teeth for tissue advancement

Often the teeth are not raised enough above the insert. The height is adjustable. To do this, tilt the car. Then loosen the screw and set the height. Normally, only the teeth rise above the plate in the middle part. In this case, the front part is higher than the back by 0.5 mm. In difficult cases, it is necessary to install gaskets between the platform and the teeth.

Adjusting the tine height

Threading the bobbin thread into the bobbin case

To thread the bobbin thread into the bobbin case, just follow a few steps. How to refuel:

1. Insert the bobbin into the cap.
2. Thread the thread into the slot under the spring.
3. Insert the cap into the shuttle.
4. Switch the machine to working speed.
5. Bring the thread up.

Modern machines have a vertical or horizontal shuttle. It is easier to work with it in a vertical position. But seamstresses say that it is recommended to purchase a model with a horizontal device. It's more reliable.

Threading the bobbin thread

Mechanism lubrication

Lubrication of sewing machine parts is necessary to extend its service life. Due to friction, the mechanisms wear out quickly. Frequent sewing requires monthly lubrication. If a seamstress rarely sits down at the machine, 3 times every six months is enough.

The oldest method of lubrication is using vegetable oil. But it quickly evaporates and also oxidizes. Motor oil is chosen with a low viscosity.

Important! You cannot use solid oil or lithol.

For modern models, manufacturers recommend purchasing special store-bought formulations. For precise dosage, use a regular syringe.

Mechanism lubrication

Setting the presser foot pressure on the fabric

The uniformity of stitches and the quality of sewing of products depends on the force with which the foot presses on the fabric. To adjust this indicator on old machines, a screw located on the rod was used. Modern devices have a regulator that is located on top of the body. It is used according to the instructions.

Important! Computerized models do not require such adjustments.

Pressure adjustment. Setting up and adjusting the Podolsk sewing machine

Setting up the Podolsk machines yourself does not take much time. These units are distinguished by their ability to work with dense fabrics. To ensure high quality products, it is important to properly prepare the device.

The setup begins with threading. Then the needle is installed. Then thread the upper thread from right to left. The flywheel is rotated towards you, the handle - away from you. When the machine is idle, the foot is raised.

Machine "Podolsk"

The rack moves to the lowest position along with the needle

The needle always moves to its lowest position at the same time as the feed dog. And the most important parameter by which this interaction is regulated is the moment the needle tip “meets” the teeth of the rack. The teeth of the rack should already be slightly lowered in the needle plate, but “peek out” a little, and the tip of the needle at this moment should be slightly above the teeth, by 1.5 - 2 mm. Actually, this is the main parameter for adjusting the rack of any lockstitch machine. If you install it correctly, your machine will stop skipping, picking up fabric and tearing thread. But, provided that other settings are made accurately.

Seagull sewing machine: setup and adjustment

“Singer”, “Chaika”, “Veritas” or other machines are configured according to similar principles. The adjustment of modern machines is different; some operations occur automatically.

The “Seagull” begins to be set up by installing the needle and thread. Then adjust the tension. Place the coil at the top. Thread the thread throughout the mechanism.

Important! There are no special features in preparing for sewing.

Setting up mini cars

Even a small machine can be configured in the same way. These are mostly modern models. It is recommended to prepare them for work strictly according to the instructions. Experts recommend not purchasing such devices. They are often brought in for repairs. However, finding parts or fixing them is difficult. Most often, the units cannot be repaired. They use fragile parts.
