How to work properly Bulgarian. Councils of masters. Be sure to read before working with the USM

Recommendations for safe work with the Bulgarian

Bulgaria( angular grinder or USM) is one of the most traumatic hand tools. The reasons for this:

• high rotation speed( more than 10 thousand rpm),
• lack of circular protection of the cutting blade with a casing( a large part of it is open),
• lack of the possibility of hard fixing the tool.

The probability of getting injured at any time is high, but knowing the how to properly operate the Bulgarian and following these rules, any woman will successfully cope with the USM.

Protective equipment

When cutting various materials with a Bulgarian to protect the body and respiratory organs, you will need:

• glasses or a protective mask protecting the eyes from three sides,
• clothing that should not hang loose, so as not to be tightened by a rotating mechanism, the
• shoes are stable, onflat sole,
• gloves are dense, better leather,
• respirator for respiratory protection if the Bulgarian is used for cutting stone, porcelain stoneware, ceramic or glass tiles.

Checking the serviceability and readiness of the

tool Before how to operate the Bulgarian , always first check the serviceability of the tool:

• the correct installation and the tightness of the protective cover. It must be securely fixed and installed so that sparks and pieces of cut material do not fly toward the operator;
• the integrity of the cutting blade, no defects on it. Any defect can lead to injury. If there are breaks on the cutting blade, chips, cracks, it must be replaced with a new one. It is not worth saving on disk, buying cheap Chinese counterfeits, it is better to purchase brands of reliable manufacturers: Kronomax, BOSH, LugaAbrasiv;
• evenness of rotation at idle speed with maximum spindle speed for 0.5-1 minutes. Strong vibrations should not be.

Protecting surrounding surfaces from damage and ignition

If the tool is used in a room for cutting water pipes, plastic or finishing materials, before is used as a Bulgarian , it must be protected from sparks by flammable objects, adjacent wallsand the floor with a damp, damp cloth or asbestos cloth.

Using a special disk for each type of operation

The most common injuries when using the EWM operators are if the disc is torn to pieces or broken from the spindle. Parts of it can fly at great speed on an unpredictable trajectory.

Professionals who know how to work safely with the Bulgarian pay great attention to the choice of work disks. Each of them indicates the purpose of the application.

• Use discs strictly for their intended purpose. Depending on the purpose of the cutting blade used, choose the number of revolutions. When cutting tiles or ceramic granite with a metal disc, incandescent materials above 600 ° C will fly in different directions. The same will happen if the tile is cut at a speed of more than 3 thousand rpm. If the diamond is cut with a diamond cloth, the tool can be torn from the hands.
• Do not use the Bulgarian in working with wood, even if it saves time. When cutting plywood as a result of overheating, toxic fumes of tar will be released, and if the cutting blade hits the knot of wood, the machine will vomit from its hands.
• Do not place cutting elements on the circular saw, even if they are ideally suited to it.
• Do not sharpen the side of the disc with metal. This will lead to a breakdown and injury to the operator.

Correct position of cut material parts

Before how to operate the Bulgarian , it is necessary to prepare the seat and pay special attention to possible interference.

• When cutting metal, remember that unlike a tree, it practically does not crack until the end of the sawing.
• The saw should always be carried out in the direction of rotation of the disc on the fractured parts, and not on their squeezing.
• It is dangerous to saw metal fixed to the ends on two supports. At the end of the sawing, the tool is clamped and torn from the hands.
• Care should be taken to ensure that there is no distortion, and the cutting plane does not change during operation.
• You do not need to press the tool when cutting. If the work advances slowly, the cutting element should be replaced.

Carefulness and comprehension in the work of

Any small thing is important in the use of the ears, so the recommendations on how works correctly with the Bulgarian should be observed rigorously.

• If the material to be sawed is a stone or other hard object that can fall under the disc, there will be a strong jerk, a breakdown of the machine or an operator's injury. Therefore, you need to exclude such opportunities and be very careful.
• When making concrete wall sections it is recommended to make sure beforehand that there are no electrical wires in the place of the cut of the reinforcement, hidden pipelines. This can be done with a metal detector and electrical detectors.

The correct position of the

• tool should always be held with both hands.
• The position of the body must be very stable to hold the instrument when it strikes.
• When cutting, the cutting line must be sideways, so that in case of tool jamming its movement is on the side of the operator, and not directed at it.

Correct start, stop, breaks

Knowing how safe it is to operate the Bulgarian , the start-up and shutdown of the machine should also be performed correctly:

• the start-up of the UWB is performed only when the disk is free;
• insert into the sawing can only rotate with a working speed of the blade. Do not let the machine out of your hands until the rotation is completely stopped. You can stop the rotation, for example, about a tree. Put the Bulgarian with a rotating working disk on the floor or the ground should not be;
• you can change the work place when the machine is completely stopped;
• When fixing the cutting element in the machine, do not tighten the mounting nut with a wrench. It is enough to tighten it together with the disk by hand;
• when cutting, you should take breaks in accordance with the manufacturer's recommendations.

Working with the UWB significantly reduces the time for repair and installation work. Following the manufacturer's recommendations on how works correctly with the Bulgarian for a particular brand and instructions on how to safely work with power tools, everyone can protect themselves from possible injuries.
