How to use a cordless screwdriver correctly. Unusual uses of a screwdriver. Preparing to work with a screwdriver

The presented tool can be mains-powered or cordless, and according to the type of work, there are drill-drivers, cordless screwdrivers, impact wrenches and screwdrivers. All these tools have the same operating principle, but perform different functions.

If a conventional screwdriver only works with fasteners, then a drill-driver can also drill holes. The impact wrench is designed for loosening or tightening bolts and nuts. The cordless screwdriver has a Phillips-shaped bit. In terms of power, this device is weak.

Working without the presented tool is quite difficult, especially if you have to tighten a large number of screws. Arranging a suspended ceiling, attaching insulation or drywall to the surface and many other actions - this is what a screwdriver is for.

How to use a screwdriver - setup stage

The design of the screwdriver is quite simple. The plastic housing houses the motor and gears that drive the bit. The bit is located at the end of the device. The case also contains LED lighting, switches for speed and direction of movement, a tightening torque regulator, and a power switch.

Principle of operation The screwdriver is also very simple. With the help of an engine, a shaft with a cartridge is driven through a gearbox, in which the necessary attachment is fixed. Now that you know how a screwdriver works, you can learn how to use it. First you need to provide safe conditions work. It is also advisable to check whether the battery is well charged. If everything is in order, then you can start working.

Before using a screwdriver, you need to insert the desired attachment into it. It is selected in accordance with the size of the head of the self-tapping screw or screw. To do this, you need to remove the chuck and coupling from the device and insert the bit into magnetic holder, which is then reinserted into the device and fixed in it.

Now you can adjust the bit rotation speed. For this purpose, the device has a special regulator. It is advisable to carry out this stage before you start using the tool. To know how to operate a screwdriver correctly, you must first understand changing the direction of rotation of the spindle, for which there is also a switch.

Using the chuck, the depth of the self-tapping screw is adjusted. The magnetic holder will need to be replaced from time to time. To do this, you need to remove it by first removing the chuck with coupling from the screwdriver, replacing it with a different type of holder of a different type and again installing all the elements in their place.

How to use a screwdriver - accuracy and safety

After the settings are made, you can start using the tool. To do this, the battery is connected to the device and necessary work. Knowing how to use a screwdriver correctly, you can avoid unwanted actions when handling the device, which will increase its trouble-free service life.

You cannot adjust the frequency and direction of rotation of the nozzle if the device is turned on and running. The device should be protected from moisture getting inside it. The room in which the device will be used must be well lit, and the electrical power supply must be stable, without fluctuations.

Do not touch the device to grounded objects, otherwise the user may receive an electric shock. Do not use the device continuously for a long time, otherwise it will simply burn out. It is advisable to work only with a working device and in special protective clothing.

A screwdriver does the same thing as a screwdriver, but hundreds of times faster. Therefore, if you need to tighten one or two screws, use a screwdriver. But if you need to assemble a wardrobe or, say, insulate a balcony with plasterboard, then you can’t do without an electric screwdriver. It is similar to an electric drill, but it drills with bits rather than drills. A bit is a special attachment for a screw, screw or self-tapping screw. Each self-tapping screw (screw, screw) has its own bit. It can be of different sizes.

A screwdriver is similar to an electric drill, but instead of a drill, it has a bit.

How to use a screwdriver?

A screwdriver is designed specifically for driving screws, self-tapping screws, and screws. Its great advantage is that it is self-contained, meaning there is no need for an outlet and the cords will not get in the way. It runs on a battery that is charged from the mains alternating current via an adapter (the battery charging process resembles the charging process mobile phone). After charging the battery, lightly pressing it, insert it into the handle of the tool.

The batteries are nickel-cadmium, nickel-metal hydride and lithium-ion. Which one should you choose? Nickel-cadmium is the cheapest, but toxic. Lithium-ion - environmentally friendly, but expensive. Nickel-metal hydride ones are intended for professionals who, as part of their duties, have to deal with repairs for a long time.

Replaceable tips, bits, are fixed in a three-jaw chuck manually no deeper than the top edge. To make it more convenient to hold the cartridge in your hands when attaching attachments, the cartridge is covered with ribbed rubber on top.

How to use a screwdriver? After required nozzle installed, put a self-tapping screw on the bat, place it on Right place, press the screwdriver button - the self-tapping screw is tightened.

The screwdriver can be used as a stand-alone electric drill. You cannot drill with it for a long time, as the battery discharges quickly. But it is quite possible to make several holes in the profile or drywall.

And yet, the main purpose of a screwdriver is to tighten screws without drilling a profile. With a certain force, the self-tapping screw will drill through both aluminum and even steel profiles.

On the tool, if necessary, there is a button for smoothly changing the speed and a reverse button if you need to unscrew the screw back.

Safety precautions

The instructions instruct you to use a screwdriver after all settings have been made.

When the tool is turned on, you cannot adjust the frequency and direction of rotation of the tip (bit). It is necessary to protect the tool from water entering it. The room in which production will take place renovation work, should be well lit.

If the screwdriver is powered by the mains, then the electrical network must be stable and the socket must be in working order to avoid damage electric shock or fire.

Do not touch grounded objects with a working tool to avoid electric shock.

It is necessary to work only with a serviceable tool wearing work clothes and gloves. Do not use the device continuously to avoid burnout.

Contrary to popular belief, not every man knows how to use a screwdriver. What can we say about women?

Such knowledge can hardly be called innate, so it is better to learn the intricacies of the work in advance if you do not want to harm your own health or the mechanism of the device.

There are several basic rules for working with a screwdriver. How you work depends on the type of device you are using. If you managed to buy a screwdriver or receive it as a gift, find out in advance how to use such a device correctly.

Let's start with the basics. There are several classifications of devices of this type that you can use in your work.

What types of screwdrivers are there?

Let's start with the classification by type of nutrition. Highlight:

• battery,
• network devices.

The former can work in any conditions, regardless of whether they are connected to the network or not. The battery is charged from the mains and holds a charge for a certain time, depending on its capacity.

Corded screwdrivers only work when they are connected to the network. This is not always convenient, and does not allow you to move far enough away from the outlet. long distance. However, when working with such a screwdriver, you don’t have to worry about the battery running out at the most inopportune moment.

By type of operation, several groups of devices can also be distinguished:

• Cordless screwdriver - not very powerful, has a Phillips-shaped bit.
• Impact wrench - designed for tightening and unscrewing nuts.
• A drill-driver not only tightens and unscrews screws, but can also make holes, having a variety of drills in its arsenal.
• A screwdriver is the most common version, used most often for loosening and tightening screws.

The speed of work depends on its complexity, the power of the device you are working with, and the properties of the materials. In short, there are many factors that influence operation, but the principle of operation of all screwdrivers is approximately the same.

How does a screwdriver work?

The bit, which is the main operating element, is driven by a small motor and gears located inside the screwdriver body. Depending on the configuration, the screwdriver may also have additional lighting, speed switches, etc.

A certain attachment is fixed into the cartridge, then, when the toggle switch is switched, the shaft with the cartridge is driven by the switched on engine. The rotation speed depends on which mode you select. In any case, touching the drill while the screwdriver is turned on is quite dangerous.

It is important to provide yourself with safe working conditions. Also, make sure the screwdriver is sufficiently charged before starting work.

Working with a screwdriver

So, when starting work, you must choose the right nozzle. This is quite simple to do - you need to take the nozzle that corresponds to the size of the head of the screw or self-tapping screw.

It is necessary to remove the cartridge and coupling from the device, insert the bit into the magnetic holder, and install the remaining elements in place. Make sure that the bit in the screwdriver is installed securely enough.

Another stage of preparation for work is adjusting the bit rotation speed. Using a special regulator, you should test in advance, without starting work, how fast the bit rotates.

Also, by switching the regulator, determine in which direction it rotates to tighten the screw, and in which direction it should rotate when it is necessary to remove the screw from the material.

In addition, it is necessary to check the depth to which the screw will enter the material. From time to time, to adjust the depth of penetration, it will be necessary to change the magnetic holder.

After the settings are made, you can start working.

If you know how to properly use a screwdriver and have made the correct settings, you can be sure that your device will last as long as possible. An important role in determining the service life of a screwdriver is played by its original quality.

At http://www.ru.all.biz/ you will find big choice devices that will become excellent helpers in your household long years. At the same time, the cost of screwdrivers will not be too high.

Please note that the device cannot be adjusted while the screwdriver is running or connected to the network. This can be dangerous, first of all, for you.

Prevent water from getting inside the device and the device falling from a great height. In addition, if the screwdriver is powered by the network, you need to make sure that the network is stable and without fluctuations.

Do not touch grounded objects while the screwdriver is running to avoid electric shock. Remember that a certain amount of caution should always be present when working with electrical items.

A screwdriver has become one of the most popular tools for interior finishing work. This is explained by the widespread use wall panels, ceiling suspended ceilings, applications wooden slats as a covering material. These works require mass use screws and for screwing them into the surface. Therefore, the issue of proper operation of the device so that it works for a long time and reliably is relevant. In this article we will talk about cordless screwdrivers, as the most popular form of this instrument.

To bring this device into working condition necessary:

1. Take it out of the case and inspect it for visible damage - cracks on the case, etc. If they are found, it is prohibited to use the tool.

2. After inspection, attach the battery to it, and then make sure that there is enough charge to start work. If the battery slowly rotates the tool spindle, you need to remove the battery and put it on charge (see how to charge it below), and connect another battery to the tool instead.

3. After making sure that the battery has gained sufficient charge, the required attachment is installed in the screwdriver depending on the nature of the work (tightening screws or drilling) and the size of the screws. We will tell you in detail about installing the nozzle further, but here we emphasize that for the safety of work during installation or replacement of the nozzle, battery must be removed so as not to accidentally turn on the screwdriver.

4. Using the controls on the instrument, select:

• operating mode - drilling, working with screws, some models also have an impact mode, for example, the.
• rotation speed of the nozzle (if the tool model has several stages of rotation, for example); direction of rotation - for drilling and tightening screws clockwise, for unscrewing screws - counterclockwise.

5. If you have to drill to a certain depth, then in screwdriver models that have limiters on the drilling depth, you need to set it.

remember, that proper preparation a tool is a guarantee of safety when working with it.

The most important part of the operation of the tool, on which the operating life of the device largely depends. How to charge a screwdriver battery depends on its type. The most common are lithium-ion batteries. Such a battery, with its compact dimensions, charges quickly and has no memory effect. The main disadvantage is the rapid discharge in the cold and the high price.

In outdated models there are nickel-cadmium batteries. They are cheap, reliable, but have a memory effect. That is, if you do not completely discharge them before charging, the battery capacity will gradually decrease.

How long you need to charge a battery depends on its type and capacity. Fastest to recruit charge Li-Ion Battery The battery of a household screwdriver charges within an hour. The same capacity will charge for 7 hours.

How do you know that the screwdriver is charged? On charger There is an indicator, for example, for the model, it is on the right. The red light is on - the battery is charging, the green light means it can be used. You can also rely on your own experience. By the charging time and the nature of the screwdriver’s operation, you can judge whether its battery is charging.

If you have a model with a nickel-cadmium battery, then you should know how to pump up the screwdriver battery, which will inevitably reduce its capacity after several years of use. And if you use the tool incorrectly, that is, do not let the battery fully discharge before charging, then it will be faster.

In order to restore capacity, you need to know how to discharge the screwdriver battery correctly. And this means a gradual decrease in charge by connecting a twelve-volt light bulb with a power of 25-40 W to it. After complete discharge, charge the battery to capacity and then discharge it again. Repeat the procedure at least 5 times. This procedure cannot completely restore the capacity, but it will significantly increase the operating time of the screwdriver.

Equipment installation

The screwdriver can be equipped with drills or attachments for tightening and unscrewing screws. When the required attachment is selected, it is necessary to rotate the chuck sleeve counterclockwise until its jaws are separated enough to insert the shank of a drill bit or screw bit between them. Then clamping is done in reverse order. There are two types of cartridges:

• the clamp is made without a key, but only by rotating the cartridge sleeve by hand;
• requiring compression using special key, which is inserted into a recess in the chuck and rotates it, resting on a toothed rim, for example, as in a gear chuck.

How to remove the chuck from a screwdriver, for example, to lubricate it or replace it if it does not hold the attachment well. IN modern models The cartridges are screwed onto the shaft and secured with a screw with a left-hand thread for reliability. This is how the cartridges are attached in screwdrivers, etc. It is necessary to unscrew the screw and unscrew the cartridge by rotating counterclockwise. detailed instructions How to do this is available in the documentation for the tool.

How to use a screwdriver correctly and safely

Working with this tool is intuitive. But you need to know certain subtleties that reduce the risk of injury and tool breakage. So, how to tighten a self-tapping screw safely with a screwdriver:

1. Read the instructions carefully BEFORE using the tool for the first time, and not after something unpleasant has happened.

2. Correctly select the maximum torque at which the protective “ratchet” will operate and no force will be transmitted to the shaft. The tool is, of course, designed for maximum effort. But first of all, Full time job at maximum reduces service life. Secondly, the likelihood that the screwdriver can be torn out of your hands increases. Thirdly, by learning to correctly determine the maximum torque, you will reduce the likelihood of damaging the surfaces into which you screw screws. This is especially true for polished and fragile surfaces. For example, in the model the maximum torque is 30 nm, but you can set it to 5 nm.

3. Select the correct operating mode. There is no need to drill in the screwdriver mode, much less tighten the screws in the drilling mode, where the speed is higher. The tool may simply be snatched from your hands.

4. Don’t forget to control the direction of rotation. We tighten the screw - the cartridge should rotate clockwise, unscrew it - counterclockwise.

5. We do not change any cutting mode settings on the fly! This threatens to break the screwdriver and is unsafe.

Above we talked about the rules safe work directly related to the screwdriver. Now about general organization work with this tool:

• Work only with safety glasses and preferably with protective gloves, especially if you are drilling materials that can crack and “shoot out” sharp fragments.
• Before drilling, make sure that there is no electrical cables and other engineering networks.
• When tightening and unscrewing screws, as well as drilling small-diameter holes, do not lean on the screwdriver. The screw or drill may break and you may be injured.
• and have different time continuous operation. In any case, it is there! And you shouldn’t bring the tool to a hot state.
• After work, you need to disconnect the battery, remove the attachment, and wipe the tool from dust.

What is a screwdriver? Essentially, this is the same drill, but a screwdriver differs from it in that it has a lower rotation speed of the chuck and, at the same time, greater torque.

Another difference is that while on a drill the rotation speed can change smoothly, on a screwdriver, as a rule, “fixed” rotation speeds of the chuck are set. This is due to the “slip” function of the screwdriver chuck: when the screw is tightened, the chuck stops rotating, although the motor is still running. This function allows you not to tear off the splines and not “drive” the screw inside.

Different types of speeds are designed for specific types works and materials, as well as the “drilling” mode. Just like a drill, a screwdriver has a reverse function. The design features of the screwdriver allow it to perform a wide range of jobs: tightening and unscrewing screws and self-tapping screws, screws and nuts, drilling soft materials.

Using a screwdriver, e.g. in production plasterboard partitions or when assembling furniture, it increases the speed of work significantly. Therefore, a screwdriver is rightfully considered one of the most common tools in any craftsman’s kit.

The designs of all screwdrivers are approximately the same. They are quite light and have a “pistol” handle, designed for working with the tool with one hand. The start key is designed in such a way as to regulate the rotation speed by pressing force.

An important element of a screwdriver is its power source. If drills are produced in both mains-powered and autonomous (battery) versions, screwdrivers, due to the nature of their application, are almost exclusively battery-powered. The battery is the heaviest and most expensive part of the screwdriver.

Household models of screwdrivers are usually equipped with nickel-cadmium batteries (designated “Ni-Cd”), while more expensive professional models are equipped with lithium-ion (“Li-Ion”) batteries. Their difference is that nickel-cadmium ones have a shorter service life (about 1000 recharges), and also have one unpleasant feature: if the battery is not completely discharged, its capacity decreases during subsequent charging.

But whatever the battery, its capacity is limited by the weight of the tool. Therefore, even the most expensive models of screwdrivers can work continuously for no more than a few hours. Some manufacturers solve this problem by introducing a second spare battery into the screwdriver kit. However, this significantly increases the cost of the tool. The battery is charged from a regular network. The charging speed again depends on the model and can range from 2-3 to 6 hours, although some models of screwdrivers provide “fast” charging in 10-15 minutes.

Operating rules

Working with a screwdriver is easy. The jaws of the chuck hold the attachment required for the job (“bit”, or wrench, or drill), and by pressing the screwdriver with some force, pressing the button rotates the chuck. If it is necessary to unscrew a screw or pull out a drill, “reverse” is activated. When working, you should follow several rules:

1. Fully charge the screwdriver before using it. At the same time, strictly follow the charging time instructions - “overexposure” of the battery in the charger shortens its service life.
2. When working, choose the “screwing” or “drilling” mode correctly - this way you will protect the motor and gearbox of the screwdriver from damage. Please remember that the screwdriver is not designed for drilling into stone or concrete.
3. Try not to throw or drop the screwdriver - it is a rather fragile tool.
4. Keep the screwdriver clean - remember that fine dust and dirt particles act as an abrasive in the rubbing parts, and the screwdriver elements fail faster.
5. Now you're in general outline Do you have an idea of ​​what a screwdriver is and how to work with a screwdriver? It's time to pick up the instrument and create!
