As far as it turned out to be perfect, "advanced" and reliable sewing machine, before each work session, an experienced master checks its setting. This is vital for trouble-free operation of the unit for a number of years before it is repaired after breakdown or replaced by another.
What parameters can be adjusted?
The need to accurately adjust the operation of the sewing machine is a consequence of not quite a correct selection to a specific material of the thread of the corresponding thickness. No less important and suitable needle tissue. For example, thick and coarse material requires a larger needle number and less - for thread. Then set the following settings.
- Length (step) Stitch - by 2 mm. Thin matter requires more frequent stitches, thick - on the contrary, but not more than 4 mm. The thickness of the fabric (its total value for several stratified layers) on electronic sewing machines using the regulator is set on the scale. The upper position of the regulator means that broaching rollers promoting the fabric will not spin. The lower the regulator's arrow, the longer the stitch machine will give out.
- Reverse (the tissue is applied on the contrary) - Movement of matter towards the tailor. You can enable this mode using the adjusting (multi-position) lever by setting the desired value. The length of the stitch remains the same - there is no need to pull out the matter and stop the process.
- Power attached by a paw to cloth clapper. Work with a more easy matter, for example, when sewing products from Silka, needs only a small decrease in the presser power from the paw. The thickened and coarse tissue needs to increase the pressure so that the fabric is accidentally shorted, which would lead to a seam curve. Setting the clamping force acting on the fabric is carried out by a screw, on the knob of which divisions are applied.
- The tension of the thread should be such that the bottom and the upper threads felt in the middle of the stratified layers of matter. On both sides of the seam looks equally. It is necessary to adjust the screw and on the tensioner itself.
Fundamental rules
Alone configure the sewing machine parameters may even beginner. It is necessary to use the instruction manual of the product, but when something is not fully clear, consult a more experienced tailor.
- Adjust the spring, With the help of which the thread is supplied up to the needle. Find her position at which the rolling threads are carried out when it is fixed using a bobbin.
- Get the desired thread pulling force - It is performed by the mechanics of the tunnel screw of the shuttle and the front on the machine itself.
- Test the operation of the device after adjustment . You will need unnecessary flap. After taking test stitches on the newly configured typewriter, check the absence of hanging stitches. If they are - the tensioner of the top thread is tightened too much, loosen it. Repeat the test stitching when the tensioner is properly adjusted, it will be smooth, uniform, not responded. At the same time, in the middle contains nodules that are not tested with a detailed inspection.
- The correct value of the presser power on the side of the paw is selected when turning a separate screw . For most models of electromechanical and electronic sewing machines, it is present in the access area and turns without much effort from the user. This is necessary for accurate and fast - for a few seconds - adjustment. Do not drag and do not weaken overly this screw. In the first case, the fabric can be tangled, in the second - the seam will be released, since the clamping paw does not presser the layers of matter properly.
- Make sure the electric drive is well-efficient n. Get the optimal frequency of rotation of its drive shaft (the number of revolutions per minute sufficient for fast and comfortable work). This parameter is set using a knob on a foot pedal. There are cases when the machine sharply starts even with a weak pressed on the pedal. The pedal itself also needs to be cleaned regularly.
- Finally, Check out the correct operation of the needle holder. The needle should not be blued, otherwise it will overtake the material with each of its skewers in a new place before overlaying a new stitch.
These rules will fit and for tincture of an old manual sewing machine.
Step-by-step process description

- Disassemble the device and check which parts were oxidized. Clean them from rusty climb and lubricate. If some part collapsed (for example, the machine stood for a long time in the conditions of high humidity) - Try to find it a replacement. If the details are removed from production - it is possible, refer to the current or milling machine for its manufacture (show a specialist drawing and what remained from the old detail). The action makes sense when the rarity is valuable in itself, and it is worth trying to restore it.
- Raise the foot and drive the typewriter without threads So that the oil spread over rubbing surfaces.
- Change the needle (if it was originally) or immediately put a new one.
- Fill the thread of the desired thickness and strength, Run a typewriter on an unnecessary piece of matter.
If the machine is sewing well - start a full sewing.
How to set up a PMZ machine?
PMZ is able to flash the tissue of any thickness and density. It is not a problem with it to sew several different things on the elasticity and the thickness of the layer together. Although this typewriter is already almost a century, it is used by experienced seams to this day. This is one of the few devices created literally for centuries. To configure the "Podolsk" model, do the following.
- Mix the required amount of thread on the bob. The cooler is placed in the back, next to the flywheel, with which the thread tensioner interacts. Install the bobbin on the cooler, and the coil with a thread is on the rod at the top of the case. Skip the thread under the tensioner washer and secure its end on the plug set. Take the frame of the cooler down until the rim of the pulley and the twist will not get in touch. For winding threads on a bobbin twist the flywheel. Drive the free edge of the thread so that the bobbin is filled with it smoothly.
- To install a bobbin with a thread, secure it in the cap so that the beveled slot remained from above. Through the latter and turns out the thread unlocking when working. Further, the same thread passes the clamping spring and comes out through the end slot. Fix the cap with a bobbin, output the end of the thread outside and close the shuttle compartment.
- Refueling the thread in the needle, be sure to block the flywheel using a locking screw, turning it towards the working machine . Before this, the mechanism that moves the needle, take the drive handle to the leftmost position. At the same time, the needle flasks should be addressed to the left. The stretching lever is allocated to the extreme upper position, then the top thread is in its ear. The flywheel is scrolled towards the seam. Stretching the thread through the tensioner and the forward guide, fill it into the needle.
- Pull the bottom thread out Turning a twilka.
If everything is done true, then when immersing the needle grabs the lower thread from the shuttle. Then she rises upstairs, and both threads are skipped through the stratified layers of matter.
Setting "Seagulls"
In the "Seagull", the algorithm of settings is similar to "Podolsky", but somewhat different. After disassembly, cleaning and lubrication, assembling the machines do the following.
- Install the thread and needle. For the installation of rapid threads, turn the flywheel until the needle product and the thread tensioner will not take extreme top positions. Insert the coil into the coil to the stop. Turn the coil with a flat slice towards the foot, fix it using the screw so that it does not fly when working. Skip the thread through the guide, the pressure mechanism, the tensioner lever, the needle holder loop and the needle hole.
- Mix the lower thread on the bobbin by filling it up to the limit. Insert the bobbin into the cap and skip her end out.
- Tighten the tilt Tension both threads and boil them under the sewing paw.
The machine "Seagull" has a disc with the working positions different from each other. If the matter is thick and coarse - the disk teeth are pulled out. In case of thin tissues, they hide. After completing the setting, fix the leg with the needle, turn the tilt to yourself. You can start the sewing process, substituting the tissue tissue into the stapler.
Setting up modern models
Use the instruction that comes in the kit. Most of the new models function equally, but the step-by-step instruction can be varied. Make the following:
- Adjust the optimal positions of working parts using special rollers to configure;
- Adjust the position of the bobbin so that its cap protects the thread from unnecessary unwinding;
- The thread is moving in a strict sequence: first through metal holes, then through the tensioner, lever stretching the thread, the buckney on the needle holder and through the end of the needle.
Details by which the thread is tensioned properly, placed within the shuttle screw, as well as on its end side (upper and lower thread).
Having finished the setting, make test seams on unnecessary flap matter. The indicator of the right seam is small nodules in the middle of each stitch, while the hanging loops are missing.
Setting the correct position of the foot is carried out using the appropriate spring. If the paw does not debug - the fabric breaks either the seam easily dismisses at the slightest tension. Guide the thickness and rigidity of matter, the parts of which you want to sew.
Set the required number of revolutions per minute. The regulator of the rotational speed of the electric motor shaft is placed on a foot pedal. If the engine speed control is unstable - disassemble and clean your contacts. With full wear of the current-carrying parts, the complete replacement of this component is required.
If the teeth regulator is present on this typewriter - insert the needle of the appropriate height, which will affect the length of the stitch. Thin thread should form a stitch with a length of no more than 2 mm. For thick stitch threads, a length of 3-4 mm is exhibited.
When is the adjustment required?
Setting the sewing machine is needed in the following cases:
- Before the start of the sewing of another product, for which the matter of other thickness and texture is used, as well as a thread of another nominal value;
- After a long idleness - it may be necessary to repair, cleaning and lubricating parts and mechanisms;
- In the process of planned prophylaxis.
Ignoring the reconfiguration of the sewing machine can lead to a breakdown of at least the needle, to confusing the thread and damage the material. The latter is particularly undesirable when the matter is "finishing", the main, and the additional quantity of it is now not at hand.
Even sewing machines of the lower price range - from several thousand rubles - can work out without any problems for ten years. And it doesn't matter, you use the machine once a few months or it works in a tense and productively for several hours a day - Adjusting, checking her work is important that this work is not stood.
