Work Protection With Angle Grinder

Safety precautions when working with an angle grinder (angle grinder)

Using an angle grinder, it is necessary to observe a number of rules that will ensure the safety of working with this tool:

Do not use an angle grinder without a guard. The cover must be between the disc and the operator. This is necessary in the event of the destruction of the disk, in order to protect a person who works with an angle grinder from splinters of the disk.

It is necessary to use discs that correspond to the “angle grinder” type in all respects: outer diameter, thickness, landing diameter, and also at the maximum speed.

Before starting work, be sure to check the integrity of the abrasive disc. it should not have even the slightest cracks and chips. A circle that has been damaged (albeit invisible at first glance) as a result of a fall or impact cannot be used. This can lead to destruction of the disc during operation and personal injury.

It is forbidden to use discs from a circular saw with an angle grinder.

The workpiece you are working with must be firmly fixed to the work surface. Hold the tool with both hands.

During metal cutting, very often there are cases when the wheel becomes jammed, the angle grinder at this moment can very strongly reject the workpiece or slip out of hands. All this happens in a split second, so the master must be prepared for such a situation and hold the car very firmly. This is very common among small angle grinders: work occurs at high speeds with a relatively small mass of the tool.

Be sure to wear safety glasses and a respirator before work. If this rule is not observed, sparks, abrasive dust, or even a fragment of the disk may get into the eyes, which, again, will lead to serious injuries. Use ear muffs.

Wear protective clothing over the entire body. During metal cutting, the cutting temperature is very high. If even one particle gets on the body, it can cause a burn. It is best to use cotton clothes.

Keep the angle grinder at the same angle during operation.

Work Protection With Angle Grinder

Use the tool for its intended purpose.

Do not use the tool for the work for which it was not designed in the required power range (for heavy work, you need a tool designed for hard working conditions; for carrying out light work, a low-power tool is enough). Do not use the tool for purposes for which it was not intended.

It is important to observe the simplest rule: have completed the cut. turn off the tool. It can be put on the table only after the disk has completely stopped.

Work zone

Keep your work area clean and well lit. Clutter, trash, unlit areas of the workplace can lead to an accident. When working with a power tool, do not allow unauthorized persons and children close to your workplace. The entire tool should be kept out of the reach of unauthorized persons, it is preferable to store them in a tool cabinet or room for a time when these tools are not used.

Remove service (installation), mounting tools (wrenches, screwdrivers, etc.) before turning on the equipment. A tool or keys located in the working area of ​​the equipment may get into moving parts of the tool, which may result in injury to the operator.

Remove personal protective equipment before starting work. The removed personal protective equipment located in the working area of ​​the equipment can get into the moving parts of the tool, which can lead to injury to the operator. Plates and large workpieces must lie securely on a support to reduce tipping or jamming of the tool.

Work environment

Do not expose your power tool to rain, snow, or use it in wet or damp places. Do not use electrically powered tools in places where there is a risk of explosion or fire due to the presence of combustible materials, flammable liquids, paints, varnishes, gasoline, etc., aggressive media, flammable gases and dust of an explosive nature. As a precaution, it is recommended that you consult a fire safety specialist regarding a suitable fire extinguisher and how to use it.

Individual security

Use personal protective equipment when working with equipment. During operation, it is necessary to apply personal protective equipment in accordance with safety measures at the workplace. The use of personal protective equipment reduces the risk of injury.

Clothing: Do not wear loose clothing, jewelry, or anything that could interfere with work or be pulled over by moving parts of the tool. Hair: Avoid getting hair in moving parts of a power tool. Wear protective hats to hold long hair.

Eye protection: a mandatory requirement is to wear special goggles, masks (ordinary glasses are not enough to protect the eyes).

Hearing protection: hearing protection is recommended during periods of prolonged use.

Shoes: in cases where there is a risk of damage to the legs with heavy objects or the risk of slipping on wet or slippery floors, appropriate non-slip safety shoes should be worn.

Head protection: in cases where there is a risk of falling objects or hitting protruding or low-lying obstacles, a hard construction helmet should be worn.

Respiratory protection: in cases where the machining operation leads to the formation of dust, use protective masks or special dressings. Use a respirator when special respiratory protection is required during work.

Avoid unintentional starting.

For equipment powered by a power supply: Before plugging the instrument into a power outlet, make sure that the switch (s) are in the OFF position.

For battery equipment: Before connecting the battery to the tool, make sure that the switch (s) are in the OFF position.

When transporting equipment, make sure that the switch is always in the off state.

Dust removal equipment

If the power tool is equipped with a dust removal and collection device, make sure that it is connected properly and in good working order. The use of a vacuum cleaner can reduce the dangers posed by spent dust and chips.

Disconnect power tools

When shutting down, ensure that the power tool is disconnected from the power supply. Disconnect the power tool from the power supply also before servicing, lubricating or making adjustments and when replacing accessories such as blades, drills, cutters, etc.

electrical safety

The electrical wiring to which the equipment is connected must always be in good condition, have protection against short circuits (equipped with circuit breakers or plug fuses).

If damage to the insulation of the electrical appliance wire is detected, carefully disconnect the electric heater from the mains without touching the damaged area and contact an authorized service center. Do not operate the tool with a defective electrical switch. The use of improvised electrical devices, such as electrical extension cords, electric plugs, etc., is unacceptable.

Before work, make sure that the power supply meets the technical requirements of the equipment to be connected.

Do not leave equipment turned on unattended.

Avoid using several extension cords that are connected in series, as this can cause overheating of the wire, and, accordingly, a fire. Do not turn on equipment whose cord or plug is damaged or after any damage. Contact a service center for inspection or electromechanical repair.

Avoid getting foreign objects into the equipment ventilation system to prevent fire, electric shock, and damage to the device. Avoid any blockage of equipment when it is operational. Avoid hit of an electric cord on a working (processed) surface. Do not allow electrical wires to come into contact with the work surface during operation.

Do not run wires under all kinds of coatings. Do not cover wires with carpets or other coatings. Arrange the wires so that they do not impede movement in the room and do not get mixed up. It is forbidden to tie wires into knots.

It is unacceptable to suspend an electric wire on nails, metal objects. It is not permissible to place wires and cords on gas and water pipes, behind radiators, etc.

When turning off the equipment, it is impermissible to pull the plug from the outlet by the cord. Always unplug the plug by holding the plug body.

When connecting the equipment to the mains, provide free access to the outlet, in case you quickly disconnect the appliance from the network. Do not use twin-core extension cords or coils on power tools with an earthed circuit. Always use three-wire extension cords or coils with a grounding conductor connected to ground. If you need to use a power tool outdoors, use only extension cords designed for outdoor use and marked accordingly (W or WA).

For extension cords with a length of up to 15 meters, use a wire cross section of 1.5 mm2.

For extension cords with a length exceeding 15 meters, use a wire cross section of 2.5 mm2.

Protect the extension cord from sharp objects, excessive heat, and in a damp or wet place. Repair all damage to the extension cord before use.

Periodically check the power cord of the instrument. If damaged, contact an authorized service center to replace it.

Do not exert much effort.

Stay attentive, watch what you are doing, and use the general senses when working with the power tool. Do not use the power tool in a state of fatigue, under the influence of drugs, AL-KOgol or intoxication. Inattention while operating the power tool can result in serious injury.

Be careful when working.

During work, do not be distracted and carefully monitor the material being processed.

Never release the tool from your hands until the moving parts of the tool stop completely. Rotating tool elements can catch on the bearing surface, as a result, you can lose control of the tool. Take a comfortable and stable position with the tool. Thanks to this, you can better control the tool in unexpected situations. Work with dry, hands free of oil and grease. Use construction gloves.

Some parts of the equipment, while in working condition, are heated to high temperature. To prevent burns, do not touch heated parts during operation.

Additional instructions for use

Use appropriate auxiliary devices (metal detectors, etc.) to locate hidden supply systems (hidden wiring, etc.) or go to your local utility company for smelting. Contact with electrical wiring may cause a fire or electric shock. Damage to pipelines can cause leakage of a substance that can be hazardous. Securely fasten the workpiece. The workpiece installed in the fixture is held more securely than in the hands.

ATTENTION! Processing certain materials can be hazardous to health and requires increased safety measures during operation. It is important to consider when working, the fact that asbestos-containing building materials, etc., are carcinogenic. Various combinations of materials can cause dangerous chemical reactions, including waste dust, etc. Consult the appropriate service at the enterprise before carrying out work.

Before using the power tool, check all parts and components for damage.

Check the integrity of the power tool housing, the correct setting of the moving parts, make sure that they do not jam. Check the availability and functionality of all switches (especially ON / OFF) and parts. If necessary, contact an authorized service center for repair or replacement.

If the power tool requires fastening, make sure it is firmly attached to a suitable workbench.

Lubricate and replace accessories and power tool parts in a timely manner. Keep the ventilation slots clean and free of dust. Blocked ventilation slots can cause overheating and damage to the motor. Only use consumables recommended by the manufacturer and those that meet the specifications of the equipment. Use only high quality supplies.

Do not use damaged, worn tools or consumables, as this may result in personal injury.


It is forbidden to use (install and operate) grinding wheels and other consumables having a maximum permissible rotation frequency of less than 11,000 rpm for discs with a diameter of 115-125 mm and less than 6000 rpm for discs with a diameter of 180-230 mm. See the appropriate markings on discs, circles, and other consumables. The use of discs with lower maximum speeds can lead to dangerous damage to the operator during operation, as well as the design of the tool.

The machine is equipped with a removable metal protective casing, with a rotation function, instead of a fixed casing. Always install a protective cover when working. Check that the casing is securely fastened before operation. The casing must be installed by the operator in such a way as to protect the operator from the released waste parts during operation.


Repairs should only be carried out by qualified persons using original spare parts. Violation of this requirement may result in significant danger to the user.
