Proper fastening of the saw blade in the jigsaw. Sawing. Preparing the tool for work and accessories

A jigsaw is not a guest, but a necessary tool in the house. Working with wooden blanks and parts, metal, plastic is not the whole list of operations performed by the tool. The jigsaw itself is long-lived, which cannot be said about the cutting equipment. The saw blade wears down over time and needs to be replaced. Another option is to update the cutting tool when processing different materials.

The tool is a smaller copy of a saw with a mechanical drive. The principle of operation, like that of a manual jigsaw, familiar from childhood, is to move the file in a vertical plane. Difference from analog, other cutting tool.

One of the critical nodes is the saw blade attachment mechanism. There are a number of tools on the market equipped with different clamps:

Side threaded clamp. Fastening is carried out by means of a screw clamping the file shank in the slot of the mechanism. Differs in simplicity of installation of a saw cloth and reliability of fixing.
Shoe fastening. It is applied in inexpensive tools of a household class. The threaded tool is placed in the slot. Fixation is carried out with two screws with an internal hole in the cap for a hex key. The main advantage is the ability to work with all types of shanks, of different sizes and regardless of the purpose of the saw.
Quick release mechanism. The most convenient of the presented methods. No additional wrench or tool required.

The saw blade belongs to consumables - in the process of work it becomes blunt, grinds off. Deformations due to off-design loads are possible. The main division of the cutting tool, according to the type of material being processed:

Wood and products based on it. The cutter is thicker. Tooth size up to 6mm. Wiring within 1mm. Blade length 60~150mm. Marked with the abbreviation HCS. On the side surface, the inscription “for Wood” or “for Wood” is made.

Increased accuracy is facilitated by a decrease in the size of the tooth to 3 mm, a small divorce to the sides. The inscription "clean for Wood".

Metal. They differ from “wooden” files in length (~50mm), small teeth (up to 1~1.5mm), undulating wiring. The inscription "metal" or "metal". HSS mark.
Plastic. Medium tooth (~3mm), slight set. The inscription "special for Acrylic".

Files are produced for ceramics, glass, drywall and other materials. They differ in geometric parameters and cutting part - instead of teeth, an abrasive coating is applied. Universal models are presented that work with wood, metal and plastic. Figured cut is carried out with narrow saw blades.

The only structural part that unites the files is the shank, designed to be fixed in a power tool.

Shank types

Initially, there were 5~6 kinds of saw blade ends on the market. Over time, the most popular remained:

U-shaped shank. Or, in other words, the American type of attachment. Used for jigsaws designed by North American manufacturers. According to geometry, it owes its name to an arcuate notch at the end of the file. An additional fixation element is a hole on the shank.
T-shaped (cruciform). European type of fixation. The pioneers are the designers of the German company Bosch. In shape, the end of the file resembles a cross.

Files with similar shanks are widely represented on the market, so there should be no problems with choosing a cutting tool.

Fixing the saw blade, as mentioned above, is carried out by three types of locking mechanisms:

Quick release. From the name you can see the main advantage - a quick change of the cutting tool. But there are disadvantages:

The mechanism works only with "native", specially designed for it, types of shank. Other types will not fit.
There are restrictions on the geometric parameters of the files - in width and thickness.

Mounting order:

mechanism, - a plastic handle-block (lever), is pulled inside the jigsaw, the stem is released;
the file is inserted all the way, with the shank into the slot;
block is released - the saw blade is fixed.

ADVICE. From practical experience: there are file clips that occur due to abnormal cutting conditions (applying excessive force, a curved cut with a wide blade). Pounding, using pliers and other "brutal" tricks is extra work and the risk of damaging the tool. It’s easier, carefully disassemble the jigsaw itself and unlock the exposed locking mechanism.

2. Shoe screw fastening. By the way, it should be noted that all types of shank are suitable for this system. The order of installation of the file:

the fixing screws must be loosened - the protective cover is shifted and the threaded elements are unscrewed (two or three turns) with a key;
in the groove (slot), with the cutting part from the jigsaw, in the direction of cutting, a file is installed;
screws (located frontally, from the bottom of the tool) are tightened with a hex wrench (should be included in the kit);
cover is returned to its place.

The main disadvantage, which manifests itself immediately or over time, is inaccurate fixation in the direction of cutting. The canvas pulls to the side. Another disadvantage is the thread breakage with excessive tightening forces. The third negative factor is the failure of the support block. It is almost always impossible to find a replacement for it, you have to grind it yourself.

3. Lateral screw fastening (on locks). It occupies an intermediate position in terms of the convenience of changing the file between the block fixation and the quick-clamping mechanism. Stages of work:

the side screw is untwisted;
the shank is installed in the opened groove;
the canvas is exposed visually and to the touch;
the screw is turned back.

Installation accuracy depends on the initial factory assembly. Over time, individual elements wear out, play appears, the file begins to walk.

In addition to the main performance characteristics, the attachment point in the jigsaw is a mechanism that affects the accuracy of cutting the workpiece. Hence, when visually inspecting the selected tool, you need to take a closer look at the work of the fastening elements:

Check for backlash - insert the file and move, there should not be a free yaw.
Turn on the tool and try to determine the presence of blade runout. Minimal displacements are difficult to notice, but visible to the eye, indicate a poor-quality assembly.
Perform a control cut (if the seller allows). The cut must match the markup - the saw follows exactly along the path of the cut.
Evidence of reliable fastening - during the test test, the cutting tool remained in place and did not fall out of the locking mechanism.

It will not be difficult to master the method of installing a saw blade in a power tool; it is enough to carefully study the instructions that came with the product. In the further operation of the jigsaw, carefully monitor the condition of the attachment of the saw blade.

Jigsaw: the nuances that are important to know

One of the universal tools is a jigsaw. It can work as a hacksaw, a grinder, a milling cutter, and a circular saw. The area of its functioning extends to various materials: wood, metal, ceramics, laminate, glass, drywall, tiles, plastic, etc. In order for everything to fully function, you need to know how to insert the file into the jigsaw correctly. And for competent and full-fledged work with each of these materials, it is necessary to choose the appropriate file or saw blade.

To work with an electric jigsaw, you need to stock up on a set of files, since different files need to be used for different materials.

Electric jigsaw: features, device and advantages

This tool is a very useful acquisition for the home workshop. It has many functions, with it you can work in various conditions and in almost any position.

Electric jigsaw device.

Thanks to the achievements of modernity and high technology, the jigsaw has ceased to be just a hand tool. After all, the use of an electric or pneumatic drive in its work makes the jigsaw an almost universal home tool. It has also been improved with built-in safety features, noise and vibration dampeners, electronic speed control and touch guard (saw blade).

In a nutshell, the principle of operation of a jigsaw can be described as follows: from the engine, the torque turns into movement, due to which the file moves forward progressively in the vertical direction.

Jigsaw design

Conventionally, the entire tool device can be divided into the following parts:

engine housing;
reducer;
sole;
handle.

If the handle is bracket-shaped, then the machine will be a closed structure, and you can keep your palm on the handle exclusively from above. The mushroom handle option can be gripped in different ways, as well as calmly change the position of your hand.

It is necessary to ensure that the sole and the body are firmly connected to each other, because. even the slightest play can adversely affect how the tool will work.

The sole of the jigsaw is placed on the surface that you saw off. Files (or saw blades) cannot be sharpened, they just need to be changed. The tool will not overheat or experience additional overload if you replace a dull file in time.

Jigsaws: main types

In terms of purpose and design, they are all the same. But there are several types of tools depending on how the file is attached to the jigsaw.

For cross shank saws.
For saws with smooth shank.
For a saw with a shank that has a hole.

You need to choose a saw blade for your tool so that it matches the work that you are going to do and the tasks that you need to perform.

Depending on the purpose and application, the files are marked with different letters and numbers.

First, decide on the materials. Relatively soft, among which rubber, chipboard, fiberboard, wood can be noted, must be processed with high-carbon steel blades. The teeth of such a file can also be different: either ground at a free angle, or ground divorced.

To make straight cuts, use a straight file with large teeth. And for any indirect cuts, it is better to choose a narrow file (5-7 mm wide).

For cutting laminate, you can find special saw blades. They will have small teeth that have a reverse slope.

For metal work, it is worth choosing parts made of high-speed tool steel. Such files come with a curvature at the bottom, made so that the metal does not bulge. They also have variable tooth geometry.

A set of saw blades for wood is marked with the letters HCS.

The steel sheet will be cut by a tool that will have a wavy profile and fine teeth. For working with non-ferrous metal, the same ones are suitable, only a little larger. True, they may differ in the shape of the teeth, because. can be different (like a wavy fabric or milled divorced).

Porcelain files require a solid abrasive edge and must be toothless, while medium-toothed files are suitable for plastic, and toothless wave-shaped files are suitable for rubber.

Consider when choosing and the geometry of the canvas. Too short a file can break, jammed in the canvas. Therefore, you need to take such a length that the end of the blade extends beyond the cut. The shape of the teeth of the file is also of great importance. Too large teeth can not only cut deeply into the material, but also break the edges of your workpiece.

Metal files are marked HSS.

By choosing homogeneous canvases, you can perform a number of different jobs. But if you need to do something special, it is better to prefer a non-uniform file. The most popular are bimetallic models with unique qualities. Due to the fact that their teeth are made of hard metal grades, they can cut wood, plastic, steel or any other material with great strength. And given the flexibility of their carrier strip, you can safely bend such files if necessary without fear of breaking them.

File attachment

Every master sooner or later faces the problem of replacing the saw blade. This can happen both from their fragility and from the need to perform different types of operations.

The file for ceramics has a continuous abrasive edge, marked HM.

The easiest way to fasten are locks that are clamped with a key. The best option with such a mount would be a jigsaw with one screw on the side. So you can fix canvases of all thicknesses and even types quite reliably. But there are many models that are widespread due to the favorable price, however, the file is pressed against them with a special block with a slot. This block must be tightened with two screws that are located frontally. During the installation process, you may experience several inconvenient moments. Even if you managed to insert the file into the jigsaw correctly, but you clamped the fasteners unevenly, the work will be skewed. It can also wedge the lock when removing the canvas. It is also possible to break the threads of the screws or break the front block due to impacts with the end of the file on the workpiece (during incorrect or uneven fasteners).

The most convenient is the jigsaw, in which the file attachment system is quick-clamping. But its disadvantage is that there are certain restrictions on the thickness of the clamped canvases.

Installing or replacing the saw blade

If we consider the quick-clamping fastening system, then we can distinguish several basic steps for replacing the file (Fig. 1.).

The jigsaw has a special lever. It is located on the body and frees the file, so you can change the blade without removing the protective cover.
Pull this lever. So you will open the lock and the stem will move forward.
Next, insert the saw shank into the jigsaw and release the lever.
You will now need to adjust the blade fixation fork to complete the installation. To do this, turn the adjusting screw, gradually achieving the desired position, or tighten it until it stops, and then loosen it a little.

A jigsaw with a locking method requires the following steps to install a saw blade.

Figure 1. The process of installing a saw blade into a jigsaw.

Open the protective screen of the instrument.
Turn the lever located on the stem to insert the file.
After you release the lever, lightly slide the blade into the clamp.
Keep in mind that a jigsaw with such a lock will accept files of limited thickness (according to the size of the slot).

To insert a file into a tool with a screw fastening system, you will need to follow a few steps:

remove the cover;
loosen the screw (usually hex keys are used for this);
insert the saw blade into the jigsaw (in a special hole near the support roller with the teeth forward);
tighten the fasteners (tighten evenly with both screws);
reinstall the cover.

Jigsaw: the nuances that are important to know

In order for your tool to work efficiently and well, and serve for a long time, you need to follow simple safety rules and do not forget about the recommendations for its operation.

Before starting work, thoroughly prepare. Depending on what exactly you are going to saw and what should come out of it, select the appropriate file and set the speed mode of the tool. For fine work, you will need a lower stroke rate setting than for fast and coarse cuts. If in the first case you have to drive the tool as slowly as possible, then in the other case, set the maximum speed with the highest degree of pumping.

Before you start working with a jigsaw, you need to set it up for a certain type of work, change and fix the file, prepare an emphasis and protection.

To avoid problems with chips, take care of a special liner that will serve as an emphasis (installed on the sole). Files and sawing speed can also play an important role in this matter.

Understand well how to insert the file correctly. Don't overtighten it because it can start to "play" which will make the cut line uneven and prevent you from doing a good job. Be careful when replacing so as not to break the file near the clamps, as often happens.

Thanks to the versatility of this tool, you get a whole set:

hand saw - you can cut and adjust not very massive lumber in place;
circular saw - it is possible to carry out longitudinal cutting of various materials (plywood, chipboard - even laminated, etc.);
reciprocating saw - you can fit the mounted lumber near the joints or where it is high, and in other inconvenient cases;
chain saw - you can safely cut thin trunks or branches, other wood waste into firewood;
angle grinder - you can cut tin, sheet materials (with a cement base), tiles, cut metal blanks (not very massive) and carry out other work;
milling cutter - a jigsaw is capable of cutting not too complex elements, curvilinear cutting, etc.

A jigsaw is a tool familiar to many men since childhood, from school labor lessons. Its electric version is currently one of the most popular hand tools that has greatly facilitated the work of home craftsmen. Unlike a hand saw, this electrical tool needs more attention, especially its most important element - a movable assembly with a removable file.

What can be a saw holder?

The saw blade is attached to the moving rod of the jigsaw by means of a saw holder - one of the most vulnerable parts of the unit. It is the blade holder that experiences the greatest loads during the operation of the device, this device especially suffers when using a blade with dull teeth, which is sometimes allowed by inexperienced craftsmen.

The material for this part is supposed to be of the highest quality, but not all manufacturers think the same way. Often it is the saw blade that needs to be repaired or replaced first. Modern power tool manufacturers are constantly working to improve this assembly.

This has led to a wide variety of saw blade holders used for electric jigsaws.

The earliest design is a bolted clamp-block. Although many firms have long since moved away from this option, models where this archaic mount is used are still found. There are two bolts on this block. One clamps the canvas, and the second allows you to adjust its position.

Both bolts must be unscrewed or tightened when mounting or dismounting the saw blade. Their heads are made for a flat screwdriver or a hex key. For such blocks, the shape and thickness of the saw shank often does not matter. There are models with one bolt. It is not necessary to adjust such a latch, the file is simply clamped by turning the bolt.

A quick-release mount is installed on most modern models of electric jigsaws. Pressing a special key releases the clamp, and the canvas easily comes out of the mount. The same manipulation will make it easy to insert the file into the slot. Such a device does not need to be adjusted, it is devoid of bolts. This type of mount is divided into two subtypes, according to the position of the movable key mechanism: side and front.

Radial clamp - a type of quick-clamp fastening. In units equipped with such a node, inserting a file is even easier. The device must be rotated 90 degrees, insert the file into the slot and release, under the action of the spring, the clamp will return to its original position and automatically fix the blade shank. All quick-clamping fasteners have a strict limitation on the thickness of the blade and the shape of its shank.

Some craftsmen prefer to make this knot with their own hands, thus trying to increase its working time. Indeed, it is not always possible to buy a part of the same quality. You can make a saw holder-block from a steel bar with a side length of no more than 2 cm. The following tools are needed for work: a drill, a hacksaw, a grinder, a vise, an accurate tape measure, a caliper.

Using an old part, you need to try to copy it by making a homemade one from a bar. If there is no skill in such work, it is better not to waste time, but to show the old saw holder and the workpiece to an experienced craftsman. If you still decide to do it yourself, be patient and, just in case, prepare a couple more blanks.

When replacing a saw blade in a jigsaw, you should pay attention to the condition of the attachment point - the most vulnerable part of the entire tool. Over time, backlash, beating of the blade, displacement of the cut from the markup may appear.

All these signs indicate an imminent problem with the fastening and it is better to find out their cause at an early stage.

How to insert a file into a jigsaw?

An electric jigsaw is not that old a tool, it is about 30 years old. Having changed little constructively, it has gone quite far from the prototype in terms of ease of operation and power. The mount holding the canvas has undergone the greatest upgrades. Shoe markings - the knot is quite simple and inserting a file into it is usually not difficult, especially since the shape of its shank and the thickness for such an attachment do not matter at all.

To put the file in the block, you need to slightly loosen both mounting bolts counterclockwise. The canvas is inserted with teeth forward, then the bolts are tightened alternately, evenly. You need to make sure that there is no skew of the canvas. You need to pull hard enough.
If there is one screw on the saw holder, then it will also be easy to change the files, you only need to tighten one bolt. To properly install the canvas, you need to check its position from time to time, slightly adjusting it with your hand. Tightening to failure is not recommended, this creates excessive vibration and may affect the quality of the cut.

In quick-clamping devices, replacing the file is even easier: pressing and holding the key, insert the shank of the corresponding file, release the key. If a click is heard, then the shank is fixed with a saw holder.
The radial mount is just as easy to handle. If the jigsaw has this fixation option, then when installing the saw blade it is very important not to confuse the shape of the shank. Currently, the industry produces files with two types of shanks: T-shaped and U-shaped. The first version of the files is currently the most common. The U-shaped shank has an additional hole for fixing the blade.

Jigsaw blades are divided into several main types, which can be determined by the shape and size of the teeth, as well as by marking. Various files allow you to successfully cope with cutting wood (boards), plywood, chipboard, plastic, metal, tiles, drywall, glass.

Wooden blanks are sawn using a long file with a tooth size of 3 to 5 mm, with a noticeable divorce. On such files there is an HCS marking, as well as an additional one - T101D, indicating the large size of the teeth.
Metal can be sawn with a shorter file with 1-1.5 mm teeth and a wave-like setting; the HSS marking and the T118A index will also help in choosing a file.
For laminate, webs with a reverse slope have been developed.

In the marking of such a file there will be an index T101BR, the last letter indicates the reverse position of the teeth.

Plastic is sawn with blades with an average tooth size (up to 3 mm), having a small wiring.
Special blades for ceramics do not have teeth at all, they are coated with carbide.
There are universal files that cut basic materials, but, of course, such products are not suitable for every job.
Models for curly cuts have a small width and index T119BO.

When operating a saw blade, one must not forget that this is a consumable material and it makes no sense to spend time sharpening dull teeth. A saw blade that has become unusable must be replaced.

How to insert into a manual jigsaw?

A manual jigsaw is a tool that has long been mastered by carpenters, its design has been honed over years of operation and has become as simple as possible. There are much fewer problems with its use and, accordingly, with the replacement of saw blades than with the electric namesake. The saw blade for this tool, as well as for the jigsaw, is a consumable. It is not repaired or sharpened.

The most problematic place is, of course, the attachment of the file. It must be installed without distortion. When fixing the web, a tight grip with the clamping bar must be ensured. The saw blade teeth must point towards the tool handle when installed. Replacing or installing a blade in a manual jigsaw is required quite often.

In order to install the file in the jigsaw holders, it is necessary to fix the edge of the file on one of the ends of the handle. Then, slightly squeezing the edges of the handle (sometimes you have to lean on them with the weight of your body), insert the second edge of the file.
The file is inserted with one hand, while the lamb must be screwed with the other. For a stronger connection, if there is not enough muscle strength, you have to use pliers, in this case the main thing is not to strip the thread.
You need to change the saw blade in the reverse order. If the canvas is broken, of course, it is not necessary to clamp the edges of the handle. Having loosened the wing fasteners, it is necessary to pull out the fragments of the canvas one by one.

Sometimes after a long operation it is necessary to replace the mount. It is not difficult to remove this knot from the jigsaw - the same lamb turns away.

There are manual jigsaws not with a flat, but with a tubular handle. Getting a file out of such a tool is not much more difficult. For such jigsaws, a simple device was invented. Two holes are drilled in the surface of the workbench or saw table.

The edges of the handle are inserted into them, and the file is tightened with clamping bars.

Installation in a jigsaw

Stationary jigsaws (jigsaws) are the result of the natural development of electric hand tools. When working with such a unit, both hands of the master can manipulate the material, which significantly increases productivity and facilitates work with overall workpieces.

For such electrical appliances, special blades are used, although craftsmen sometimes adapt the blades of a manual jigsaw. Pin files have a special pin at the end, which makes the fastening more secure. Pinless, respectively, do not have a special device and remain flat. Cloths can be with a divorce of teeth and without it.

Installing the file in the machine is actually quite easy.

The saw blade is fixed in special grooves, first in the bottom, and then in the top. The teeth of the blade are directed down and towards the sawyer. You need to tighten the canvas with a lever, the stretched file should ring from the impact.
Pinless files need to be tightened especially carefully, they tend to pop out of the clamping device, however, remain popular due to their wide range of uses for sawing complex shapes.

Possible problems

A jigsaw is a fairly reliable electrical device; during normal operation, all its components can work for quite a long time without any interruptions or interference. But the file holder, even with the most careful handling, is doomed to breakage and eventually replacement, not to mention files, replacement of which is a natural and necessary event.

A jigsaw in the household is an indispensable thing. Modern models of electric jigsaws can cut not only wood. They can also handle plastic and aluminum and even ceramics. But for each material, you should purchase your files. How to choose the right file for the material, and how to insert the file into the jigsaw, will be discussed in this material.

Common in files

Regardless of the clamping system of the jigsaw itself, all files have the same, standard slots for the holder. Therefore, there is no need to look for files for a specific model of a jigsaw. They are perfect for any model. But how to insert a file into a jigsaw, it will already depend on how the mount itself on the power tool is designed.

The difference in files

Looking at the shop window, you can see that some saw blades have large teeth, while others have smaller ones. This is what says that each file has its own material. It can be understood that a file with large teeth is more suitable for soft wood, while cutting metal blanks can only be done with a file with fine teeth.

Files differ both in the materials from which they are made and in length. A more detailed classification will be given below.

Classification of saw blades for electric jigsaws

Sometimes, with some files, specialists make cuts in different materials. We will be guided by the advice of experienced experts and explain why it is best to use this or that file, based on their recommendations.

T101D - large teeth, so the cut will be rough, but the fastest. Great for ordinary wood (timber, board). Handles chipboard and plywood.
T101B - the teeth are smaller, and therefore the edges of the punch will be kept clean. Suitable for plywood and plexiglass.
T101BR - the letter "R" at the end means reverse. So the teeth are located in the opposite direction, even though the file itself is the same. It is best to cut glued wood, laminate with such files.
T119VO - due to the thin cross-section of the file, it can perform very accurate curly cutting on materials such as fiberboard or chipboard, keeping their edges as clean as possible.
T118A - fine teeth and high-strength steel of such saw blades allow them to make cuts in metal blanks and plastic.
T224D - great for sawing/cutting aluminum blanks.

Features of fasteners in electric jigsaws

Now that we have figured out a little with the choice and purpose of the files, we will figure out how to correctly insert the file into the jigsaw. Let's start with the fact that each company is constantly striving to improve tool mounts, making them more comfortable and simple, and not at the expense of reliability. Manufacturers correctly believe that the less hassle the tool will deliver during the maintenance process, the more likely it is that they will purchase it. But, meanwhile, there are still early models, the fastening of the files in which are far from perfect. We will analyze the types of running fasteners and how to insert a file into a jigsaw, based on each fastener, in more detail.

Clip-on fastening (shoe type)

This is becoming less and less common today. The shank of the file is inserted into the slot of the clamp and the bolts are wrapped. In the process, the saw blade is adjusted, otherwise some distortion may occur, and the cut will be far from ideal. The advantage of such clamps is that any kind of saw blades with any shank configuration are suitable for such jigsaws.

Sometimes there are fasteners with just one bolt. For example, some models of the German company Protool are equipped with such mounts. How to insert a file into a German electric jigsaw, and how to adjust it then? Everything is done simply. The shank of the file is inserted into the slot of the clamp, and the bolt is wrapped. No special settings are needed here anymore.

Most of the current models of jigsaws intended for domestic use are equipped with this. If the clamp is frontal, the key is in front, if it is side, respectively, on the side. To equip the tool with a file, you just need to press the key, insert the file into the slot of the clamp and release the key.

In new models of jigsaws, changing the file is even easier. For example, for those who are interested in the question of how to insert a file into a Makita electric jigsaw, let's say that often in the latest household class models, the quick-release key is pressed by pressing a protrusion (key) located on the front small casing of the upper protection that fits the front part . The rim of the casing in this case moves forward from the edge from which the pressing is carried out, the saw shank is inserted into the slot of the holder, the key is released, the casing is in place, and along the way, the saw shank is fixed in the mount.

You can verify the strength and operation of the fastener by pulling on the file. If it doesn't come out, then everything is fine. It would be useful to recall that it is strictly forbidden to take hold of the saw blade when the tool is connected to the mains (with a battery - not on the fuse).

This is one of the varieties of quick-release fasteners. The jigsaws of the German company Stayer are often equipped with this. How to insert a file into a jigsaw with a clamping mechanism of this configuration? Everything is simple. We scroll the head of the clamp to the side, insert the file with the shank into the slot of the clamp to failure, release the head. For those who do not understand anything or are too lazy to read, you can watch the following video.

So, as can be seen from the above, there is nothing difficult either in choosing consumables or in replacing files. By and large - we press the key, the old file pops up, we insert a new one into the slot in its place, release the key. Everything is ready. You can work.
