To maintain a good condition of the power tools by order of the head of the organization, a responsible worker who has a group W should be appointed

Electrical appliances that are used in everyday life and in production does not matter to which type of equipment they include, should clearly correspond to the list of tasks for which they are intended. The basic requirements for the power tools are usually listed in the operating instructions that accompany these or other equipment. However, for all types of tools, there are general requirements that suggest a detailed review for safe and high-quality work.

Power tools help significantly accelerate repair work, but it is necessary to use them correctly.

Types and types of power tools

Tools in their characteristics are accepted for professional and domestic ones. Professional power tools features the increased strength of the main nodes. This tool is intended for long, intensive use.

As a rule, professional power tools satisfies the requirements of work in conditions of long overload and increased wear. Professional power tools can be used around the clock, often in severe environmental conditions, without much harm for the functional nodes of the device.

Household or non-professional power tools differs from professional models exclusively by its technical characteristics. It is much less resistant to wear. Power tools should be soldered and used with small breaks in the work, often giving it to relax. The advantage in this case is the price of such equipment, choosing a tool from a well-known manufacturer's company, you can purchase not only a cheap, but also a high-quality power tool that will serve you for a very long time.

General requirements

The general requirements that any power tools must be corresponded primarily for the convenience of its operation.

Electrical diagram of the perforator.

Requirement 1: Any powerful power tools must have a smooth start function. It does work with such a tool more secure, because the device does not twitch in the hand when the start button is pressed. Significantly reduces the load on the network due to the reduction of starting currents.

Requirement 2: If the operation of the power tool due to functional features leads to a large dust or fine particles, the device must be equipped with a dust removal assembly or is equipped with a special nozzle to which the vacuum cleaner needs to be connected.

Requirement 3: The device is equipped with a reverse function - the power tool shaft must rotate in both directions. A big advantage will be the presence of a function of smooth adjustment of the number of revolutions.

Requirement 4: The device must be protected from an invalid mechanical load. The clutch of the ultimate moment will work if the drill or drill, and thereby protects the gearbox of the power tool from damage.

Classification of power tools

Harvesting vibration perforator.

Before you begin working with the power tools, you should understand what kind of type it should be used. It is necessary to understand which class of the power tool is more expedient to apply to fulfill a task.

Class requirements:

Grade 1 - In the tools of this class, all parts that are under voltage have a double or particularly enhanced isolation. Class 1 power tool plug supplied with ground contact.
Grade 2 - nodes under the tool voltage are isolated. In special cases, some elements have double isolation.
Grade 3 - In the power tools of this class, the nominal power supply may not exceed 42 V. Internal or external chains in such equipment cannot be under any other voltage. Power supply of such a class of devices is provided by means of autonomous current sources. Power supply from a network using a transducer or a power transformer with an idle stroke voltage of no more than 50 V. The secondary chain of the transformer should not be grounded.

Important little things and requirements

Table Characteristics of the screwdrivers.

Electrical manufacturers indicate the degree of protection of the power tools on the housing. Double square talks about two-level protection, where the first square is the designation of the insulation of all internal electrical nodes of the tool, the second is the protection of all conductive hull elements available for the touch.

It must be remembered that the power tool feeding from the network must be connected to the current source of a fixed cable of sufficient length and flexibility for comfortable operation.

In case of damage to the insulation of the internal components under voltage, the class 1 tools must be grounded parts accessible to the touch. Electrical equipment 2 and 3 class is usually not grounded.

Power tools 1 and 2 classes are designed for voltage not exceeding 220 V, in the case of equipment intended for power supply from a DC power, and 380 V for devices that feed on AC.

Features of security requirements for power tools

Connecting and rules for performing work with power tools.

Before you start working with power tools of any class, it should be checked:

complete set and reliable fastening of all parts of the device;
the serviceable condition of the power cable and forks, insulating parts, housings, handles and body elements must be integer, without cracks and other physical damage;
good condition of the switch, it must gently change the position; If the switch sparks, hences, changes its position only with a strong pressure, the instrument should be replaced and immediately show a specialist to repair;
work at idle.

Additional requirements

A flexible non-removable power cable in a class power tool must be equipped with residential grounds, which is connected from one end with the ground pin on the plug and ground clip inside the instrument housing. The same refers to equipment intended for nutrition from a single-phase network. To connect a three-phase power tool, the use of a four-core power cable is required.

Power tools are forbidden to ground with zero wire. In this case, manufacturers do not guarantee a good operation of the equipment, as well as the security of the personnel working with it. Fower Cables 3 class electrical cables must be equipped with plugs having a design other than forks connected to a voltage network voltage over 42 V.

As for portable lowering transformers, separation transformers, as well as converters, such devices must be equipped on the top voltage side cable with a plug outlet for connecting to a network of 220 V or 380 V.

Working with drilling and other rotating power tools in mittens is not allowed.

In the process of working on a drilling power tool, you should install the drill to the location, previously scheduled to the core, then turn on the power tools and submit the drill by clicking on the handle. Press should be uniformly until the end of the drilling.

In the case of the drill in the hole, the power tools should stop, remove the drill, clean the hole, and then continue to work.

When drilling through holes at the end of the work, pressing the tool should be reduced.

3.10. When working with a grinding tool, the circle should be uniformly move along the material being processed in the lateral direction.

3.11. Do not include equipment in the work if a prohibiting security mark with explanatory inscription is installed on the control panel "Do not include - people work!". Only the employee who installed it can take it.

4. Requirements for labor protection in emergency situations

4.1. It should be stopped when at least one of the following faults occurs:

damage to the plug, cable (cord) or its protective tube;

damage to the lid of the brush holder;

sparking brushes at the collector accompanied by the appearance of circular fire on its surface;

leakage of grease from gearbox or ventilation channels;

the appearance of smoke or odor characteristic of burning insulation;

the appearance of increased noise, knock, vibration;

breakdowns or cracks in the cabinet part, handle, protective fence;

damage to the working tool.
