The modes of operation of the screwdriver. How to use a screwdriver: step by step instructions. Screwdriver breaks needed

The rechargeable screwdriver is a tool that must be present in the working kit of any home master. Its multifunctionality allows you to easily perform work both by twisting and on the unscrewing of various types of fasteners (screws, screws, screws), as well as drilling holes.

Let's look at how drill a screwdriver works and discern in nozzles and devices.

Tool package

Usually this tool is sold in special suitcases, where for each part is intended its place.

The drill screwdriver itself consists of a main tool and a removable battery, which recharges from the household electrical network.

For charging, a special charger is used, which is equipped with a set.

Rechargeable Battery Charging Procedure

It is necessary to insert the battery into the device, while observing the polarity (the corresponding signs "+" and "-" are affixed and on the battery and on the device), i.e. Plus combined with a plus, and minus - with a minus.

A glowing red diode on the device panel shows that the charging process goes. It lasts this procedure from 3 to 5 hours.

The battery has a recharge protection, so it can be left in the device and for more, but not more than 24 hours.
In the process of recharging the battery and the device itself can be heated, which is not a malfunction indicator.

Bits - Nozzles

Complete with a screwdriver go there are several types of bits with a different form of the working edge.

Direct edge bits are designed to work with fasteners having one slot (slot). Depending on its length and depth, a suitable bit is selected.

Similarly, the shape of the cruciform bits is also selected - the width of the slot and the size of the fastener cap itself is taken into account. For reliable operation, the edge of the bits must be tightly into the slots, otherwise there is the likelihood of "licking" of the faces of the slots.

For mounting bits in the cartridge, a special nozzle with a magnetized holder is used, which does not allow the design to break up and reliably holds the bat in a variety of positions.

To secure the nozzle with the bat, you need to unscrew the movable part of the cartridge.

Insert the nozzle and wrap the cartridge until you stop.

There are very convenient bilateral bits that can be fixed in the cartridge without nozzle.

Installing torque

The drill has an adjusting ring to set the torque on which its values \u200b\u200bare applied.

It is necessary in order to set the most suitable value when working with materials having various hardness.

For example, to twist the screws in drywall (with a small force), the range of values \u200b\u200b2-4 is suitable, and for solid wood, the torque can be set on the maximum number on the ring.

Such adjustment helps to avoid rapid damage to the fasteners slots.

During operation, you can change the frequency of revolutions, increasing or reducing the force of pressure on the tper tool.
This allows you to stop the tool in time when you start twisting the self-press or screw.

Direction of turns of the cartridge

In the drill design - the screwdriver there is a switcher of the pushing type with which you can change the direction of rotor speed to twist or unscrew the fastener.

On both sides of the tool near this switch there is a reference designation. By pressing the switch, you can perform a reverse.

It should be remembered that it is possible to change the direction of revolutions only with a complete stop of the electric motor.

In the middle position, the switch blocks the tool operation. This blocking is used for the time replacement or drill.

If necessary, the chip-screwdriver cartridge can be replaced. It should be borne in mind that it is fixed with a screw with the left thread and then it is necessary to unscrew it clockwise.

Access to this screw can be obtained through the front of the cartridge.

The instrumental kit also includes a set of drills of different diameter. All of them are designed to work in relatively soft materials.

Click drills in the cartridge is similar to the nozzle with a bat. (See photo above)

To care for the instrument, it is enough to wipe its body with a damp cloth and then dry, it is impossible to use household chemicals and solvents.
The freezing of the battery is not allowed.

Before starting work, make sure that all parts of the instrument;

After a long break in the operation, the battery is still discharged, in which case it should be recharged;

It is necessary to make sure that the electric cable does not pass in places of drilling and the water and gas pipeline pipes are not laid;

When the tool is running, it is necessary to avoid frequent braking of the electric motor, this may fail the battery;

Take carefully to check the polarity when connected to the charger;

The first charging of the battery can last up to 12 hours;

Avoid moisture from entering the tool housing;

Screwdriver - a tool with which you can quickly screw fasteners (screws, screws, screws); It is used to collect furniture, hang shelves, drill holes, install suspended ceiling or crate. To understand how to properly use the screwdriver, it is worth learn more about how it works, what work can be performed with it.

Modern devices are divided into subspecies that differ in functionality.

Exist:

screwdrivers with which you can only twist fasteners;
wheelners used to twist the hexagons;
rechargeable screwdrivers - the least powerful simplest tools;
drills-screwdrivers used as well used for drilling holes.

By type of power, devices can be battery or network. The first are considered more convenient because they allow you to carry out the work away from the outlets, including on the street.

The screwdrivers can be with a key cartridge for fastening the drill or quick-release.

Selection of tools

The most important indicators to pay attention to when buying is the speed of rotation and the power of the screwdriver.

The speed of rotation affects the functionality of the device. To twist or unscrewing fasteners, the tools are suitable, whose speed does not exceed 350 revolutions per minute. The drilling will require devices, the speed of rotation of which is higher or equal to 1000 revolutions.

If you plan to purchase a battery screwdriver, you should find out its type. The most common devices with lithium-ion elements that are distinguished by a long service life. They are recommended to choose if the device will use often.

If working with the use of the screwdrity is rare, the nickel-cadmium element is more suitable - they are cheaper, they are not so prone to self-discharge as lithium-ion. For extremely home use, devices operating from the network will also be suitable.

Additional parameters that will make work with a screwdriver easier and more convenient:

illumination of the working area;
pulse increasing torque used for drowning fasteners;
shock mechanism;
increase the speed of rotation.

Design

The tool consists of a housing in which the engine and gear mechanism is located; cartridge (clamp for replaceable drills); Battery or cord to connect the device to the network.

Preparation for work

Before using the screwdriver, you need to pick up a nozzle that is suitable in size to the cap of the fastener. To install into a tool with a quick-inspection cartridge, the nozzle is pushed between the cams, turn the sleeve clockwise. To fix the nozzle in the device with a key cartridge, the key is inserted into the socket, turn clockwise until it enaches.

A device equipped with a battery should be charged, and the device running from the network is included in the outlet.

To make sure that the screwdriver is working, at first it is turned on in good. Look, whether the direction of rotation of the nozzle is fastened to the direction of the fastener thread.

Screwing and twisting fasteners

The instruction on the use of the device is simple:

The tip of the nozzle is inserted into the slot of the self-press or screw, turn on the device.
To increase or decrease the spinning speed, you should strengthen or reflect the pressure on the start button.
When the self-tapping will be twisted, the mechanism will automatically work the mechanism of limiting effort, after which the work will stop.
To unscrew the screw, the nozzle is placed in the slot, after setting the lever direction of rotation of the nozzle in the opposite direction.

Features of operation

Incorrect work and breakdowns may occur after switching to the instrument operation modes during the rotation of the cartridge. That this does not happen, it is recommended to perform all operations only after turning off the screwdriver and stop the engine stop.

It is also necessary to properly select the torque of the device, given the hardness of the material with which:

DVP and plasterboard. To spin self-tapping screws into these materials, 1-4 modes are used.
Wood solid rocks. The regulator ring is moved to the maximum value.

Important! It is better to set a smaller torque value than required. When choosing an overpriced value after twisting the screw, the cartridge of the screwdriver will continue to rotate, and will not stop, as it should be. Slot will be damaged.

Use the screwdriver as a drill can only be briefly. With a long-term load of a tool that is not intended for drilling, the electric motor can overheat, which will damage the device.

Safety regulations

It is impossible to make moisture, sand and construction dust inside the tool.
The room in which the work passes must have high-quality lighting. In the event that an electricity operating screwdriver is used, you should make sure that the network is stable, there are no voltage drops.
Switching operation modes are carried out only when the tool engine is completely stopped, in the off state.
If the tool begins to work with an effort, the speed of revolutions reduce or turn off it for a while.
It is impossible to touch the instrument of grounded items: the worker can strike the current.
So that the screwdriver regularly worked, the cartridge is regularly lubricated and cleaned from dirt.

Knowing how to use the screwdriver correctly, you can not make common mistakes of beginners, which significantly reduce the service life of the device and sometimes lead to the complete output of the instrument.

An indispensable power tool with the speaker name screwdriver is actively used in construction work. The most common procedure with such an appliance is the replacement of the drill. Sometimes it seems that this process is very complex and practically impossible. However, in fact, replacing the drill in the screwdriver will not be much difficulty, the main thing is to step by step to follow the instructions and pay attention to the details.

Features of the screwdriver

Under the screwdriver implies the same drill, but it has a smaller speed of rotation of the cartridge and the ability to adjust the twisting force. Multiple twisting and spinning with their own hands has not yet delivered pleasure. The screwdriver will help to quickly and high quality and promotion fasteners.Also, with the help of this device, you can perform holes in materials of various density - metal, wood and stone. The meal of the screwdriver comes from the mains or battery.

The construction device is divided into the following types:

standard;
rechargeable screwdriver;
drill screwdriver;
wheel.

All Tool Types differ only to the assignment: the screwdriver (normal) applies only in operation with fasteners, the drill will help to drill the necessary hole, the screwdriver is designed to twist and unscrew the elements of fasteners with a cross-shaped "hat", the instrument with the speaker name wrench perfectly copes with bolts and nuts .

Replacing the cutting tool

"Tail" drill the screwdriver is fixed in the cartridge. It happens different sizes, like nozzles. With the incorrect installation of the cutting tool, the screwdriver can cause damage to the workflow and harm to health. For example, due to the "wrong" drill, openings of different sizes with a damaged surface may be obtained. The sharp element with the "departure" from the cartridge will cause serious injury.

Most modern screwdrivers have cam cartridges.They consist of a cylindrical body, as well as sleeves and cams. When the sleeve rotates clockwise, the cams are simultaneously pressing the drill.

The process of its replacement is simple, but has a number of individual characteristics. The whole process can be described as follows:

it is necessary to choose the necessary nozzle (bit) for drill;
then you need to take a cutting tool and install it in the center of the cartridge (between the revealed "cams");
after that, it should be fixed, turning the sleeve climbing the sleeve (with a key type cartridge, the key is installed in the recess);
tighten the sleeve before fixing the nozzle.

Change the drill is easy, but before you need to pull the previous one. The following options for the development of the situation are:

standard removal of drill (the cartridge has no damage);
pulling the drill in the absence of a key;
removing the stuck cutting element.

With good operation of the screwdriver of problems when replacing its working tool, it should not occur- Elementary operation. To do this, take a key that is designed to weaken the cartridge, and insert it into the deepening. Current counterclockwise. Splitting is carried out at the expense of special teeth that are available on objects. There is also another option to seize the drill. To do this, turn on the screwdriver the reverse rotation mode, keep the external cartridge housing and press the "Start" button. Thus, the drill is easy to free.

In the absence of a special key, the drill can be removed using a crust screwdriver or nail.It must be inserted into the deepening on the patron and fix it half. The opposite part of the cartridge is twisted. However, if such spout does not bring the result, we take the gas key or vice - these tools will help to increase the cartridge turning. If the previous options for pulling off the drill were fiasco, then you should resort to "heavy artillery". In some cases, get the drill makes it difficult to external damage. In the current situation it is necessary to relax "cams" using gas keys and vice. Fully clamp the cartridge keys and produce rotation (unscrewing).

This process welcomes simultaneous use and key, and vice. You can also take a hammer and bring them easy blows on the cartridge - vibration from shock contributes to relaxation.

The radical option at the very hopeless situation will be twisting the cartridge from the screwdriver.To do this, it is necessary to squeeze it in the vice and with force to knock out a cutting tool from the inside using a bandwicker. Naturally, after such a procedure, the screwdriver should be attributed to the repair. Summing up, it is worth noting that the procedure of inserting drills into a screwdriver is quite simple and even one who has never done this can cope with it. The main thing in this process is to follow the recommendations.

How to use a screwdriver?

It often happens that without a screwdriver can not do. The screwdrity is an indispensable assistant in the manufacture of the suspended ceiling, the mounting of the drywall. Repair works are complicated, if there is no screwdriver at hand, which can easily spin the screws and fasteners. In the household sphere, it is in demand no less than in professional activities.

However, how to use the screwdriver, not all the tool owners know about it. There is no hard thing about it, the main thing to adhere to some rules and recommendations for beginners.

Tool varieties: characteristic signs

Screwdriver can be classified for the following varieties:

Drill-screwdelt
Gaikovert.
Rechargeable screwdriver
Standard screwdriver

The principle of work in the tools is similar to each other, but still there are differences in functionality.

Drill-screwdriver is able not only to spin the screw, but also to drill a hole. The wrench specializes in bolts and nuts. The third representative is a battery screwdriver, designed exclusively for twisting / unscrewing the fastening elements with a cross-shaped hat. The latter species is characterized by low power, unlike the above.

What is the screwdriver? Device setup.

In the plastic case there is a motor and a gear mechanism that actuates the bit that is installed at the end of the screwdriver. The device is provided for the presence of a start-up toggle, direction switch and speed, diode highlighting and tightening time regulator.

The principle of the instrument is very simple. The nozzle, pre-fixed in the cartridge, moves with a shaft, which proceeds to move from the motor operation through a gearbox. Before using the screwdriver, it is necessary to find out whether the battery is charged, and the right nozzle is installed.

Immediately before performing the work, you need to look after such a nozzle so that it corresponds to a self-supersay hat or screw.

To install the desired nozzle, it is necessary to pick it up with the magnitude of the cap of the fastener element and fasten in a magnetic cartridge holder. First, the cartridge with the coupling must be removed from the device, and after fixing the bits, the cartridge must be fixed to the casing of the screwdriver.

Then you need to assign a suitable frequency of bits. Setting is performed by means of a special regulator. The required mode is set in the tool disconnected state.

Before using the power tool, you must adjust the depth of screwing the fastening element. After some time, the need to replace the magnetic holder may occur. To change it to be removed, the cartridge, magnetic fastening and coupling. Next, the cartridge with the coupling is fixed back to the screwdriver block.

After the desired nozzle (bit) is selected for the drill, given the magnitude of the screw screw and the configuration of the recesses (straight, cross), it must be installed in the heart of the open cams, and fasten in the cartridge by turnover the sleeve at the time direction. If a key type is selected, then the key is set to the deepening on the cartridge, and then turns on the hourly until the nozzle is secured. The end of the nozzle is placed in a scarpet groove. Before the device is running, check the accuracy of the direction of rotation direction, the direction must match the screw of the screw.

Increased pressure on the start button adjusts the optimal rotation speed. With full immersion, the screw is activated by the mechanic limiting effort, and then the drill stops.

After the end of all settings, you can take the use of power tools. After examining the instruction manual of the screwdriver, you can prevent possible malfunctions in the process of handling the device, thereby increasing the service life of the tool.

It is not allowed to configure the frequency and direction of nozzle revolutions in the included state of the device. You can not touch the power tools to grounded objects, otherwise a person can strike the current. Do not use the device for a long time because it can burn.

The room in which the screwdriver is best to be well lit, and the power supply is constant, without jumps, it will avoid equipment malfunctions. Work should be held in specialized clothes and only with a good tool.

Is it possible to use drill as screwdriver

The screwdriver can be used as a drill. The cartridge mechanism makes it possible to firmly fix the drill with a cylindrical tail. To get started, you will need to install the drill on the clamping cartridge.

Be careful, as the design is not provided to do the holes, especially the solid wood, metal or concrete, because there is a high probability of breakage of the planetary gearbox.

Maintenance screwdriver + (video)

There is nothing remarkable in service, since today modern models have increased strength and withstand even falling from a small height. The cartridge should be regularly lubricated and cleaned. Avoid moisture ingress, sand dirt in the middle of the instrument. Follow the overload of the screwdriver if you feel that the screwdriver begins to work with effort, lower the speed of revolutions.

Device and appointment of power tools

Screwdriver applies to twist and unscrewing various fasteners. The tool can be cutting the thread and drill. It makes it much easier and speeds up work. Sculptors are used in everyday life, construction, assembly of furniture, in the car service, wherever need to work with a lot of fasteners.

Screwdriver can be rechargeable and network

The main elements of the screwdriver:

Cartridge.
Torque adjustment coupling.
Speed \u200b\u200bshifter.
Engine in the screw is screwed.
The reducer is enclosed in the tool housing.
Reverse switch.
Power button.
Handle rubbled to eliminate slipping.
Battery.
Network cord.

Sculptors feed on batteries or from the network.

Types of bits for screwdriver: how to choose

To select the nozzles correctly, you need to study their varieties. First, determine the type of shape of the shank and diameter. It happens from 1/4 to 1 inches.

Classification of shanks:

main;
special;
combined.

Types of major bits:

Types of special bits:

Combined bits have two types of shape of the shank or one, but of different sizes. For example, a slotted shank and the stars.

Example of a combined nozzle

Slot Shank and Star

Determine the bit length that you need to work. It ranges from 10 to 200 mm.

Depending on the shape of the shank, the nozzles have a definite labeling:

SL (SLOT) - Slotsey;
PH (Philips) - Cross-shaped universal;
PZ (Pozidrive) - Cross-shaped with additional subtle ribs;
T (Torx Hole) - Stars;
H (Hex) - hexagon.

An important characteristic is the steel brand from which the bit is made. The nozzle may have a torn coating. The durability of the equipment depends on it. The main types of steel and covers that should be preferred:

Nozzles differ depending on the purpose:

twisting and unscrewing;
drilling;
skill;
polishing;
milling.

Considering all the considered parameters, you can easily choose the necessary bits.

How to work with nozzles

Different cartridges are installed in screw leads. Consider how to change the nozzle in all types.

Magnetization and hardening of the nozzles

A large number of nozzles produce in China from a soft material. Therefore, they quickly lose their shape. The new bits grabs quite a while. To extend the service life, the nozzle must be hardening. You will need: Machine oil, gas burner or gas stove, small oil capacity from any tin can, piece of steel wire.

The hardened bit will serve longer than the usual.

Video: Overlaying Bit Oil

For the convenience of work, especially in hard-to-reach places, the nozzles are magnetized. This can be done in several ways.

Method 1.

You will need to purchase special screwdrivers. Insert the bit there. The square window magnetizes, and the stepped - on the contrary.

Device for magnetization and demagnetization

Method 2

Method 3.

Method 4.

As a result, the nozzle will magnify the fastener better than the new one.

Video: Magnetization of bits with neodymium magnets

After purchasing a screwdriver, observe simple recommendations for use. And then the tool will work for a long time and qualitatively:

before connecting and removing the battery, turn off the screwdriver;
do not bring the tool until overheating, take breaks;
correct torque adjustment clutch;
after applying high revs, install the minimum and lead the engine in a fast-minute engine so that it is cooled;
check the power screw cable, and at the battery-network cord of the charger. If the tool or charger periodically loses the network, the wire must be replaced;
do not use screwdriver in the rain and snow. In a wet environment, you can only work under the canopy.

How to regulate turns and effort

The rotational speed varies with the switch, which is located on the screwdriver housing. High speed is used for large bolts and screws, as well as for drilling, if such a function is present.

Speed \u200b\u200bshifter

Many models have an effort limit coupling. Its presence in the power tool can be determined by a rotating ring with numbers. Some users do not understand the values \u200b\u200bof the coupling and do not touch it. Using the ratchet, you can adjust the depth of screwing the screw. In the too soft material, the fastener hat is easily comfortable and can pass through. When using fine fasteners, a very high torque can destroy it. The ratchet prevents the cutting of the slot from the screws and wear the bits of the screwdriver. To determine the desired value on the adjusting ring, make several goals starting with the minimum. For drilling mode, the maximum torque is used. But only with such a function.

Coupling Limitations Efforts

The start button also adjusts the speed of rotation, but not more than that is installed by the switch. Suppose you put the switch to the first speed, which is declared to 800 rpm. With a maximum press on the trigger, the speed above will not rise. And torque in the maximum mode will be low, that is, you will not be able to twist the large screws and drill. And if you set the switch to the maximum speed, you can drill and turns will be much higher.

Adjust the speed, torque and reverse in the disconnected state of the tool.

Tool use options

The screwdriver can not only twist and unscrew the fastener. To make the tool, it can be found, it can be found a lot of applications.

Is it possible to use screwdriver as a drill

You can only drill a screwdriver if this mode is provided by the manufacturer. Then the drilling will be safe. Carefully read the instructions. On the coupling, this is the last position or pictogram with the image of the drill.

Designation of drilling mode

In screw leads with a drilling function, a quick-release or key cartridge is installed. A magnetic or snatching cartridge will not be able to keep the drill and ensure the safety of work. To replace the equipment, do the following:

Another application

Using various nozzles, the tool can be performed by the following works:

You can still find a lot of applications for this tool. But remember that you need to work in protective glasses and gloves.

Care and storage

disarmatically disassemble and clean the internal elements of the screwdriver from Nagara, dust and dirt;
in case of unstable work, conduct diagnostics. Check the brushes wear so that the engine anchor should not be changed;
do not leave the instrument in rooms with high humidity and under the sun. The same applies to the battery;
do not keep the battery next to keys, coins and other short metal objects. With random contact with poles, a short circuit of the battery will occur. As a result, a fire may occur;
at the end of the working day, take clean rags and wipe the tool. Rag can be slightly moistened with water without using detergents;
keep screwdriver needed in a dry medium with a plus temperature. Use a case or other packaging so that the tool is not covered with dust.

Work screwdriver, observing the safety and rules described in the instructions. Pick the right tool. And then the tool will serve you for a long time.

Instruction: how to use a screwdriver

The word "screwdriver" is present even in the lexicon of kindergartens. After trying on the construction helmet and taking toy tools, they begin to get acquainted with their destination. Even children understand that without a screwdriver could not do, if, for example, you will need to hang in the room the picture or replace the spoiled door lock. But how to use a screwdriver, not anyone and adult is known.

The screwdrity is used in wood, metal, and if necessary, the preparation of a small hole in the concrete wall, if more large-scale work is coming, it is better to use a drill or a perforator.

Screwdriver and Drill: Subtleties Differences

The presence of a plug indicates a drill, and the battery is a screwdriver. Typically, such a response is given by the streets when they are asked about the distinguishing criteria for instrument data. He is incomplete and not quite correct, as you can use the screwdriver by connecting it to the power grid.

Those who are more attentive to have seen and enjoyed this tool indicate the rapid termination of its operation - immediately pressing the corresponding button. The reason is the brake of the eleg, which there is no drill. Even when it was turned off, the cartridge is still moving and can damage the screw.

The screwdriver has a quick-release cartridge and a torque regulator. Setting the latter to the maximum position, the screwdriver used becomes a drill.

Being only the buyer, it is necessary to assess the convenience of working with the tool. Not bad if he has a fastener loop. This small device needs to take advantage when the tool is not in operation.

Scheme of the device of the screwdriver.

How to use a screwdriver, you can read in the instructions to it attached. But even more principled will be the solution to diligently explore the device of this device and only then following the recommendations, to accurately collect it. For example, the cartridge of the screwdriver after replacement must be securely secured by a special screw. If there is an error, then during the starting start it can jump from the shaft that performs rotational movements. Then you have to correct this trouble or even refer to the traumatologist.

In addition, by taking the tool assembly, you need to be careful with the electric motor. An incorrectly installed switch and more than necessary, the wriggled wires threaten the screwdriver.

By purchasing a battery device, you need to know: the first time the battery can be charged to twelve hours.

If there is a desire to experience this device, applying it as a drill, then large revs are needed. Because in this case it is necessary to use the screwdriver a short time. As an alternative, a different method is used: reducing the speed of rotation.

Proper nozzle - effective result

Scheme of nozzles for a screwdriver.

What to choose the nozzle to perform the task most effectively, you need to think in advance. It is necessary to work with wooden materials, and took the metal drill - the result can upset the initiator of the repair. It happens that the drill has to be replaced. The screwdriver can be used when it is necessary to prepare a small deepening in the wall made of concrete. But if global work is coming, then you should use a shock drill. It is useful here and the perforator.

If you purchase special nozzles (bits) inexpensive, then bolts, nuts and self-tapping screws can not be spinning quite efficiently. Usually on cheap models do not have a workshop located on the workspace. The material from which bits are made should be durable. Otherwise, such an unpleasant situation will be formed: we use a tool for a long time, and a little incorrectly turned - and discovered wasteless faces. Exit - replacement of the nozzle.

Choosing bits, do not save on additional properties (magnetic), which, when working in hard-to-reach areas, have their advantages.

After selecting the bits, you need to correctly configure the tool. In this regard, it is necessary to realize how the spindle rate changes is occurring: they pay attention to the switch.

What kind of depth is required to complete the screws, adjust, using the cartridge.

Screwdriver breaks needed

For a screwdriver to serve the owner for a long time, it is necessary to use them and remember: loading the mechanical parts of this construction tool at the maximum should not count on prolonged and at the same time efficient operation. If the electric motor works on maximum revolutions, it can overheat and lead to malfunctions in the winding. Special nozzles are also unwritten: contacting with materials intended for processing, they are heated. Therefore, experts recommend periodically to arrange breaks to cool the drill. With the help of water, it is not necessary to solve this problem: sharp differences of temperature indicators are undesirable.

The compilers of the instructions to the tool are warning: to adjust the bits rotation course, the frequency is prohibited if the screwdriver is enabled. Where this apparatus has to be used, sufficient lighting is required and a stable operation of the power grid.

It is necessary to be careful if there are objects with grounding. It is strictly forbidden to touch them a screwdriver, the blow to the current to anyone will not be pleasant. Defending himself, a person must treat the tool carefully. For example, it is necessary to ensure that the housing does not threaten moisture.

Use the screwdriver carefully. Prepare holes in the concrete surface easily, but it should not be harmful to their light and bronchoms. Without special protection (a respirator is carried out here) it is better not to take for this repair operation.
