Gloves For Working With Angle Grinder

Features of application of the angle grinder for wood

Sawing wood with a hand tool comes with a number of features. Wood is a heterogeneous natural material, its density is unevenly distributed. After a relatively loose area, a denser area may suddenly begin, there may be defects hidden in the thickness, once filled with resin in the process of tree growth. There may be developed or underdeveloped knots, and sometimes ingrown foreign inclusions (nails, wire, shot, or even bullets that fell into a tree in the forest, for example, during a hunt).

Thus, it is almost impossible to unambiguously select the operating mode of the cutting hand tool. This can lead to jerks, the energy of which has to be extinguished with the help of the hands; in special cases, the instrument may even break out. If a cutting tooth hits metal, it can be broken and ejected by the next tooth at a sufficient speed to cause serious injury.

When adjusting this tool for sawing wood, the craftsmen often removed the protective cover, which is categorically unacceptable, given the above-mentioned features of wood, as a natural material with unpredictable variations in properties. If the need to use an angle grinder as a circular saw nevertheless arises in order to ensure safety and get the greatest effect, you need to purchase a special disc designed specifically for this tool.

Advice

If you need to use an angle grinder for sawing wood, it is better to use a small diameter of 115 or 125 mm. The 230th circles are much more dangerous, they have a large inertia, in the event of an emergency, it is not possible to stop their rotation immediately. Attaching the saw blade to the angle grinder \. The direction of rotation must be taken into account, it is often indicated on the disc itself in the form of arrows. Circular saw teeth have special solders that increase their efficiency. A disc mounted on the contrary will not be easy to saw. When purchasing saw blades for an angle grinder, you need to pay attention to the following parameters:

  • Saw diameter;
  • Required cutting depth;
  • Shape and number of teeth.

If you plan to cut wood infrequently, then it is better to choose a saw blade with teeth that have a variable set. If the main material on which it is supposed to work is chipboard, it is better not to take a saw with a large number of teeth. If the angle grinder will be used on the construction of a log structure, it is better to purchase a circular saw. Sawing boards will require paying attention to the depth of cut and the diameter of the blade.

A circular saw will last longer, if teeth that are blunt during operation are sharpened, it is better to entrust this to a specialist. In order to sharpen the saw, the same angle grinder can only be used with a special abrasive attachment. Also for this operation you will need a stationary vise.

How to choose a wood saw blade for an angle grinder?

an angle grinder, or an angle grinder, is a tool that has no analogues in its popularity. If initially the scope of its application was limited to operations that determined the name of the unit (grinding and technologically related types of material processing), then gradually the range of application of this power tool and the replaceable nozzles produced for it has incredibly expanded. Now the angle grinder cuts metal, grinds various surfaces, removes dirt and old paint and much more.

The presence of a rotating rod made it possible to adapt the angle grinder for sawing wood. They began to try to install saw blades produced for circular saws on it. Manufacturers of attachments for this tool reacted by developing and producing special wheels, similar in effect to circular saw blades, but adapted to high speeds and increased safety requirements for hand tools.

Saw blades for angle grinder

Saw blades for wood for an angle grinder have been developed by various manufacturers and, accordingly, have several varieties. The simplest and definitely the most budgetary option is to install a circular disc of appropriate dimensions on an angle grinder. both the outer diameter and the diameter of the inner mounting hole. For an angle grinder, which, according to its dimensional characteristics, is classified as small, a 125×22 mm circle is suitable.

Technically, a disc with a diameter of 230 mm can be installed on a small angle grinder, but for this you have to remove the protective cover, which is absolutely unacceptable. The user’s hands of the angle grinder are in close proximity to the rotating work surfaces and any abnormal situation can cause serious injury. Using such a wheel on an angle grinder can cause serious safety violations and is strongly discouraged for beginners.

Any misalignment, including those associated with the unevenness of the wood structure, can cause the disc to jam and, as a consequence, a sharp jump of the entire unit, up to the point that it can escape from the hands and make a dangerous unpredictable flight. The circular saw blade is not designed for such fast revolutions that the spindle of an angle grinder produces; this results in its excessive heating, which affects the strength of the steel. As a result, when skewed, the saw wheel may collapse with the scattering of fragments at high speed in unpredictable directions.

Special attachments for sawing wood, developed for UMSH, have significant differences from the circular saw blade. Let’s consider the most common options for sawing wood. On sale you can find saw blades similar to circular saws, having an increased set of teeth, which significantly reduces the likelihood of their jamming. In addition, the differences for the manufacture of such a disk are that other alloys are used, this reduces the risk of destruction of the disk when it is heated.

Further attempts to protect the blade from jamming led to the combination of circular and chain saws in one product. A chain similar to a chainsaw chain moves freely along the working surface of the disc, which absolutely excludes jamming. There are quite a few modifications of such a hybrid. Craftsmen with the help of such a combination saw successfully saw branches and can even saw not very thick trees.

A completely new direction in the evolution of circular discs was marked by the invention of a special nozzle that is suitable for working on various materials. This universal disc is made of a special composition. tungsten carbide. There are no teeth at all on such a saw blade. This type of disc allows you to cut a wide variety of materials well, it can be considered the safest disc for sawing wood of all that is used on an angle grinder.

Sawing with an angle grinder

If there is no other way out, that is, a special saw for wood is missing (broken) or an urgent little work is required, of course, an angle grinder can help out. However, we must remember that the main purpose of this machine is still not in sawing wood. To use an angle grinder as a hand-held circular saw, you will need to stock up on one or more specialized attachments.

To avoid distortions and jamming, you need to saw in a comfortable position and fix the tool with both hands. The best results can be obtained if you do not remove the special guide handle, with its help it is much easier to control the angle grinder. It is not at all easy to saw off the workpiece correctly with an angle grinder, the mode of operation will constantly change due to the heterogeneity of the wood. Therefore, during work, it is better not to be distracted and watch how the cut is going.

Safety engineering

Using an angle grinder for sawing wood is a responsible and unsafe undertaking. That is why it must be well thought out and prepared. There are not so many basic security requirements:

  • Before installing the saw blade, the angle grinder must be de-energized;
  • It is impossible to remove the protective cover in any case, even if the diameter of the disc is larger, it is better to postpone the work and purchase the appropriate tool;
  • It is imperative to use protective equipment: gloves and goggles (mask);
  • When sawing wood, you cannot use a large angle grinder; it will not be possible to stop it when it jams;
  • the angle grinder must be kept strictly at a right angle, otherwise it is difficult to avoid teeth snagging and pulling the angle grinder out of hands;
  • Under no circumstances should the start button be fixed, otherwise the emergency shutdown of the angle grinder will be impossible.

For how to cut wood with an angle grinder, see the following.

Gloves for working with an angle grinder

When using an angle grinder, a number of rules must be followed to ensure the safety of working with this tool:

Do not use an angle grinder without a protective cover. The guard must be between the disc and the operator. This is necessary in the event of a disc break in order to protect the person working with the angle grinder from being hit by disc debris.

It is necessary to use discs that correspond to the “angle grinder” type in all parameters: outer diameter, thickness, bore diameter, as well as 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 injure a person.

Do not use circular saw blades with an angle grinder.

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

During metal cutting, very often there are cases when the wheel is jammed, the angle grinder at this moment can very much throw the workpiece off or slip out of your hands. All this happens in a split second, so the master must be ready for such a situation and hold the car very tightly. This is very common among small angle grinders: work takes place at high speeds with a relatively low weight of the tool.

Be sure to wear safety glasses and a respirator before working. Failure to do so can lead to sparks, abrasive dust, or even a splinter of discs in the eyes, again resulting in serious injury. Use ear protectors.

Wear full body protective clothing. When cutting metal, the cutting temperature is very high. If even one particle hits the body, it can cause burns. It is best to use cotton clothing.

Keep angle grinder at the same angle during operation.

Use the tool strictly for its intended purpose.

Do not use the tool for work that it has not been designed for in the required power range (heavy work requires a heavy-duty tool; for light work, a low-power tool is sufficient). Do not use the tool for purposes for which it was not intended.

It is important to follow the simplest rule: if you have made a cut, turn off the tool. It can be placed on the table only after the disc has come to a complete stop.

Work zone

Keep the work area clean and well lit. Clutter, debris, unlit areas of the workplace can lead to accidents. Keep bystanders and children away from your work area while operating a power tool. Keep the entire tool out of the reach of unauthorized persons, preferably in a tool cabinet or room when not in use.

Do not allow electrical wires to come into contact with the work surface during operation.

Do not run wires under any kind of cover. Do not cover wires with carpets or other covering. Place the wires so that they do not obstruct movement in the room and do not get tangled. Do not tie wires in knots.

It is unacceptable to suspend the electrical wire on nails, metal objects. It is unacceptable to place wires and cords on gas and water pipes, behind radiators, etc.

When unplugging the equipment, never pull the plug from the outlet. Always disconnect the plug from the outlet by grasping the plug body.

When connecting the equipment to the mains, provide free access to the socket in case of a quick disconnection of the appliance from the mains. Do not use twin extension cords or reels on power tools with a grounding loop. Always use three-wire extension cords or coils with a grounding conductor connected to earth. When using the power tool outdoors, use only outdoor extension cords that are marked (W or WA).

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

For extension cords longer than 15 meters, use a wire cross-section of 2.5 mm2.

Protect the extension cord from sharp objects, excessive heat, and damp or wet location. Repair any damage to the extension cord before use.

Check the power cord of the tool periodically. If damaged, contact an authorized service center to have it replaced.

Don’t make a lot of effort.

Stay alert, be aware of what you are doing, and use your general senses when operating a power tool. Do not operate a power tool while fatigued, under the influence of drugs, alcohol, or drugs. Inattention when operating a 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 let go of the tool until the moving parts of the tool come to a complete stop. Rotating parts of the tool can snag on the supporting surface and lose control of the tool. Find a comfortable and stable position with the tool. This gives you better control over the performance of the instrument in unexpected situations. Work with dry hands, free from oil and grease. Use construction gloves.

Some parts of the equipment, while in working order, reach high temperatures. To avoid burns, do not touch heated parts during operation.

Additional instructions for work

Use appropriate assistive devices (metal detectors, etc.) to locate hidden supply systems (hidden wiring, etc.) or contact your local utility company for fusion. Contact with electrical wiring may result in fire or electric shock. Damage to the piping can cause leakage of a substance that can be dangerous. Secure the work piece securely. The workpiece, installed in the clamping device, is held more securely than in the hands.

ATTENTION! The handling of some materials can be hazardous to health and requires increased safety measures during work. It is important to take into account when working, the fact that asbestos-containing building materials, etc. are carcinogenic. Combinations of materials of various kinds can cause hazardous chemical reactions, including waste dust, etc. Consult the appropriate company department before proceeding.

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

Check the integrity of the body of the power tool, the correct adjustment of the moving parts, make sure that they do not jam. Check the presence 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 securely attached to a suitable workbench.

Lubricate and replace accessories and power tool parts promptly. Keep ventilation slots clean and free of dust. Blocked ventilation slots can cause overheating and damage to the motor. Use only consumables recommended by the manufacturer and those that fit the specification of the equipment. Use only high quality consumables.

Do not use damaged, worn out tools and consumables, as this may cause injury.

ATTENTION!

The use (installation and operation) of grinding wheels and other consumables with a maximum permissible speed of less than 11000 rpm for discs with a diameter of 115-125 mm and less than 6000 rpm for discs with a diameter of 180-230 mm is prohibited. See appropriate markings on discs, wheels, etc. Consumables. The use of discs with a lower maximum speed can lead to dangerous damage to the operator during operation, as well as to the structure of the tool.

The machine is equipped with a removable metal protective cover, with a pivoting function, instead of a non-removable cover. Always install the protective cover when working. Check that the hood is securely fastened before operation. The installation of the cover should be done from the operator’s side in such a way as to protect the operator from the loose parts during work.

Important!

Repairs should only be carried out by qualified personnel using original spare parts. Failure to do so could result in significant danger to the user.

Eye and face protection:

It is recommended to use protective goggles with the face shield to protect against fine dust

Metal processing without cooling

  • The highest dust emission is accompanied by the processes of abrasive processing of metals: cleaning, polishing, grinding, etc.
  • The resulting dust is 30. 40% by weight of the material of the abrasive wheel and 60. 70% of the material of the workpiece.
  • The intensity of dust emission is related to the size of the abrasive tool and some technological parameters of cutting.

According to GOST 32602-2014 “Rules for calculating emissions of pollutants into the atmosphere during machining of metals based on specific indicators”.

What remedies to choose for your operation?

The degree of protection required is determined by the intensity of the pollution:

Short-term grinding work

3M ™ Aura 9300 respirators are among the most comfortable respirators available. They fit perfectly, do not create discomfort when working. They do not obstruct breathing thanks to the exhalation valve. Perfectly compatible with 2890 goggles.

In addition to comfort, this respirator provides a very high level of respiratory protection.

These goggles provide superior eye protection when grinding and cutting metal.

Thanks to a well thought-out ventilation system, these goggles do not fog up even during prolonged work.

These headphones provide a high level of protection while maintaining the highest level of comfort, even during very long periods of work.

Formation of aerosols and dust when working with various abrasive wheels

When grinding metal or cutting it with an abrasive wheel, a large amount of waste material is formed. It consists of metal particles and particles of the circle itself.

Depending on the operation, type of circle and type of metal, these particles can have different sizes.

The classic solution is an abrasive bakelite wheel 6 mm thick

How long aerosols can stay in the air?

Now you can see: when grinding or cutting metal, a huge amount of waste materials is formed, of different shapes and sizes. And all this easily gets into our respiratory tract, eyes and is harmful to health.

But in addition to grinding products, a high noise level is generated during operations.

In both cases, the noise level is exceeded.

This means the use of hearing protection is required.

Siz when working with an angle grinder

When purchasing one or another hand-held power tool, how many of you, dear readers, study in detail all sections of the attached instructions? I think not. Usually, its reading is limited to familiarization with the technical characteristics and how to get IT to work. Such negligence can have absolutely irreparable consequences. And it is on this that we would like to dwell in more detail, and specifically on the need for personal protective equipment when working with various power tools.

Despite the fact that manufacturers are trying their best to secure the tool supplied to the modern market, it still remains quite traumatic.

A threat to life and health is, first of all, electricity itself, working attachments (drills, cutting and grinding discs, saws, knives, etc.) that circulate at great speed, their flying fragments, random uncontrolled emissions of chips, shavings and crumbs of the processed material, dust, noise and vibration.

Today there are a huge number of different means of protection that allow you to preserve hearing, vision, protect all parts of the body from mechanical and thermal injuries. Perhaps, when using the tool at home, many of them seem superfluous, but for professionals they are simply necessary.

Safety glasses and face shields

The modern range of goggles is large enough. They vary in material and shape. Glasses with transparent glasses are used to work with power tools. angle grinders, circular saws, planers, etc. They consist of a body in which glasses are directly attached, and temples. A headband can also be used as a fixing element.

To protect against small particles flying from the front and from the side, you can limit yourself to open glasses. In case of possible multidirectional emission of solid particles, closed glasses with direct ventilation are preferable. With a large formation of dust, which is typical, for example, when working with grinding machines, or splashing non-aggressive liquids (for example, when wet grinding), closed glasses with indirect ventilation are the best option.

Considering the possible impact force of traumatic particles, the speed of which can be 45 m / s and more, it is better to pay attention to glasses with glasses made of special polycarbonate. They are highly durable and have little abrasion with proper care.

Safety goggles are tailored to the nature of the job to be done and the ability to customize them for a secure fit on the head. over, there are models that can be used over corrective glasses.

To prevent the glasses from fogging up, you can treat them with special compounds, or you can do with improvised means. rub the inner surface of the glasses with baby or glycerin soap and polish it with velvet.

Face shields are more practical, since they protect not only the eyes, but also the skin of the face and neck from mechanical damage.

For working with power tools, shields with a head mount and shields with a helmet attachment (of course, if it is supposed to be worn), with movable or fixed glass holders, are most in demand. Such masks are made of durable polycarbonate glass, including three-layer glass, and may contain additional steel mesh.

Respirators and masks

For the most part, power tools designed for work accompanied by the formation of a large amount of dust are equipped with special dust collectors or equipped with nozzles for connecting to an industrial vacuum cleaner. But, for example, in drills, rotary hammers and jackhammers, built-in dust extraction systems are quite rare, and in this case, the user must take care of respiratory protection himself.

The simplest means of protection in this case can serve as disposable gauze respirators. They are not burdensome when worn for a long time, but, alas, they are not always effective enough. If you often have to deal with work of this kind, it is better to purchase a professional mask with a replaceable filter. However, full-face masks do not need to be supplemented with goggles. Having spent one time to purchase such an accessory, you will for a long time get rid of the need to swallow dust when cutting and drilling concrete, during intensive work on sawing wood, etc.

Hearing protection

It is known that absolutely silent power tools simply do not exist. During operation, they create the most unpleasant shock noises for hearing.

Practice has proven that repeated prolonged exposure to noise levels of 70-90 dB can cause significant weakening or even loss of hearing, and the instructions for most power tools indicate a possible level of 85 dB. This means that during intensive work, personal hearing protection must be used. headphones or earplugs. The choice of both is extremely extensive.

Earplugs can be disposable or reusable, with a string or rigid rim. As for full headphones, you can find electronic ones with the ability to adjust the level of external sounds. suppress loud and amplify weak.

Do you prefer listening to music while working? And this is not a problem, since there are headphones with a built-in stereo receiver. Communication headphones absorb loud noises while allowing you to hear normal speech.

Protective aprons and suits

Even if you do not work with welding, but are only going to cut an angle grinder steel, it is worth getting special clothing made of fabric impregnated with a flame retardant compound. Hot sparks generated during the cutting process scatter within a radius of up to 2 meters, burning and igniting easily combustible objects. Oiled overalls not designed for this can cause severe burns.

For the safety of the user, chainsaws are equipped with a number of protective functions and devices, however, when working with them is an integral part of the professional activity, it makes sense to purchase special trousers containing inserts made of durable fiber material in the legs. When the saw is thrown back, the most likely affected area is the knee-lower leg. After a tear on the top layer of fabric, the fibers wrap around the headset, causing the saw to jam, providing additional protection against injury.

Gloves and shoes

Hands that are in direct contact with a power tool need protection, perhaps even more than all other parts of the body. They are the first to take on scalding sparks, thorny splinters and blows. A wide range of specialized gloves and mittens are available to protect the hands, depending on the type of work involved. When purchasing the latter, it is worth remembering that thread gloves are unacceptable for working with a tool, the working nozzle of which makes rotational movements. And these are angle grinders, circular saws, chain saws, drills, hammer drills, etc. Universal for working with almost any power tool are light leather split leather gaiters, which provide reliable protection against thermal and physical damage to the hands and wrists. However, they are not comfortable enough in summer. For work in heated rooms and during the warm season, it is better to get fabric gloves with leather inserts.

Work shoes should be as comfortable and durable as possible, as well as exclude all kinds of thermal and mechanical injuries. There are specialized safety shoes for welders, turners, riggers, etc. In the first case, the emphasis is on heat resistance, in the second. on preventing sharp chips from getting inside, in the third. on excluding self-harm as a result of falling heavy objects, etc. Which shoe is right for you depends on the type of proposed activity. For example, when making openings with an angle grinder, protect your feet with steel-toed shoes, and if you are going to cut metal, look for a shoe for welders. In any case, the shoes should be non-slip, with an impenetrable sole (you never know what will fall under the foot), a durable upper and preferably non-conductive.

In terms of protection against electric shock, it is preferable to have electrical insulating mats at a stationary place of work, and it is also necessary to monitor the integrity of the power cords. In addition, please be aware that double-insulated power tools must not be connected to extra-grounded sockets, while tools with a grounding pin on the plug (electrical protection class 1) must only be connected to grounded outlets. When using drills as mixers for mixing various mixtures and solutions, you should be warned against possible electric shock using dielectric gloves.

And, of course, do not forget about the first-aid kit: in which case, you should always have dressing materials, pain relievers, hemostatic, disinfectants and anti-shock agents at hand.

And I would like to end with what we started with. with instructions. Its careful study and strict implementation of all the requirements and recommendations set forth in it, taking into account the information provided, will make working with any power tool as safe as possible.

Disconnect Power Tools

When finishing work, be sure to disconnect the power tool from the power supply. Also unplug power tool before performing maintenance, lubricating or making adjustments, and when changing attachments such as blades, drills, cutters, etc.

electrical safety

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

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

Before operation, make sure that the power supply meets the specifications of the connected equipment.

Do not leave equipment running unattended.

Avoid using multiple extension cords in series, as this may cause the wire to overheat and result in a fire. Do not switch on equipment whose cord or plug is damaged or after any damage. Contact a service center for inspection or electromechanical repair.

Avoid introducing foreign objects into the ventilation system of the equipment to avoid fire, electric shock and damage to the device. Avoid locking the equipment in any way while it is in working order. Avoid contact with the power cord on the work (processed) surface. Do not allow electrical wires to come into contact with the work surface during operation.

Do not run wires under any kind of cover. Do not cover wires with carpets or other covering. Place the wires so that they do not obstruct movement in the room and do not get tangled. Do not tie wires in knots.

It is unacceptable to suspend the electrical wire on nails, metal objects. It is unacceptable to place wires and cords on gas and water pipes, behind radiators, etc.

When unplugging the equipment, never pull the plug from the outlet. Always disconnect the plug from the outlet by grasping the plug body.

When connecting the equipment to the mains, provide free access to the socket in case of a quick disconnection of the appliance from the mains. Do not use twin extension cords or reels on power tools with a grounding loop. Always use three-wire extension cords or coils with a grounding conductor connected to earth. When using the power tool outdoors, use only outdoor extension cords that are marked (W or WA).

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

For extension cords longer than 15 meters, use a wire cross-section of 2.5 mm2.

Protect the extension cord from sharp objects, excessive heat, and damp or wet location. Repair any damage to the extension cord before use.

Check the power cord of the tool periodically. If damaged, contact an authorized service center to have it replaced.

Don’t make a lot of effort.

Gloves For Working With Angle Grinder

Stay alert, be aware of what you are doing, and use your general senses when operating a power tool. Do not operate a power tool while fatigued, under the influence of drugs, alcohol, or drugs. Inattention when operating a 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 let go of the tool until the moving parts of the tool come to a complete stop. Rotating parts of the tool can snag on the supporting surface and lose control of the tool. Find a comfortable and stable position with the tool. This gives you better control over the performance of the instrument in unexpected situations. Work with dry hands, free from oil and grease. Use construction gloves.

Some parts of the equipment, while in working order, reach high temperatures. To avoid burns, do not touch heated parts during operation.

Additional instructions for work

Use appropriate assistive devices (metal detectors, etc.) to locate hidden supply systems (hidden wiring, etc.) or contact your local utility company for fusion. Contact with electrical wiring may result in fire or electric shock. Damage to the piping can cause leakage of a substance that can be dangerous. Secure the work piece securely. The workpiece, installed in the clamping device, is held more securely than in the hands.

ATTENTION! The handling of some materials can be hazardous to health and requires increased safety measures during work. It is important to take into account when working, the fact that asbestos-containing building materials, etc. are carcinogenic. Combinations of materials of various kinds can cause hazardous chemical reactions, including waste dust, etc. Consult the appropriate company department before proceeding.

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

Check the integrity of the body of the power tool, the correct adjustment of the moving parts, make sure that they do not jam. Check the presence 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 securely attached to a suitable workbench.

Lubricate and replace accessories and power tool parts promptly. Keep ventilation slots clean and free of dust. Blocked ventilation slots can cause overheating and damage to the motor. Use only consumables recommended by the manufacturer and those that fit the specification of the equipment. Use only high quality consumables.

Do not use damaged, worn out tools and consumables, as this may cause injury.

ATTENTION!

The use (installation and operation) of grinding wheels and other consumables with a maximum permissible speed of less than 11000 rpm for discs with a diameter of 115-125 mm and less than 6000 rpm for discs with a diameter of 180-230 mm is prohibited. See appropriate markings on discs, wheels, etc. Consumables. The use of discs with a lower maximum speed can lead to dangerous damage to the operator during operation, as well as to the structure of the tool.

The machine is equipped with a removable metal protective cover, with a pivoting function, instead of a non-removable cover. Always install the protective cover when working. Check that the hood is securely fastened before operation. The installation of the cover should be done from the operator’s side in such a way as to protect the operator from the loose parts during work.

Important!

Repairs should only be carried out by qualified personnel using original spare parts. Failure to do so could result in significant danger to the user.

The need to use PPE

The use of protective equipment when working with abrasive tools using an angle grinder is the most important condition for maintaining the health of the operator.

  • 100 out of 100 cases when using abrasive materials additional operator protection is required
  • Today, the use of PPE in small enterprises is practically absent.

Below we will explain why it is imperative to use PPE when working with an angle grinder and abrasive discs.

Breathing protection.

Half mask

These filter half mask kits provide an even greater level of respiratory protection while providing significantly greater comfort. This is very important for long-term work.

Long-term grinding work, cleaning and cutting of metal.

Such work requires even more serious protection, since the consequences of the influence of harmful factors tend to accumulate.
