An angle grinder or simply a grinder is by no means as simple as most citizens would like. When handling this tool, you can not only break firewood, but also remain without fingers in the truest sense. In order not to burn down half of the dacha cooperative and not to leave by ambulance on early leave for medical reasons, you should not forget a few important things.
1. Fastening quality
The fixing nut on the tool is not provided for beauty at all. It must be tightened properly so that the disc does not have any play during operation. If the deviation is 3 mm or more, then the nut should be tightened even tighter. You can check the backlash as follows: draw a straight line at the place of the cut, put and clamp the disk on the grinder, then turn on the tool and bring it without touching the markup. If the backlash is serious, then it will immediately be noticeable. An attempt to work with a dangling disk may result in a rupture of the latter.
2. Cable damage
One of the most insidious malfunctions, which, with the connivance and wrong approach, can cause serious injury. First, the grinder abruptly stops working, then the person tries to fix the wire, when suddenly the tool turns on abruptly and breaks out of his hands. To prevent this from happening, the wire should be checked only after removing the disc. It is also strongly recommended to always ensure that the wire lies flat, does not tangle or break.
3. Cut direction
Until now, there are no strict rules regarding the direction of cutting the disk of the grinder, which is why the adherents “on themselves” and “on themselves” continue to converge in frantic battles on the Internet. The indisputable advantage of the cut "from oneself" is that the sparks do not obscure the markings. However, in this case, a person exposes himself to a much greater risk, since the angle grinder disk in this case spins in his direction, and if something happens to the disk, then all the fragments will fly, including in the face. For this reason, it is generally accepted that cutting "on yourself" is generally safer.

4. Size and brand
As practice shows, many citizens still need to be reminded that any angle grinder should use only “native” disks. Do not try to save on the quality of the tool. A hospital bed will always cost more. The same applies to the size of saw blades. You should not even try to install discs of a larger diameter than indicated on the angle grinder, since in this case the risk of damage to the disc is radically increased due to a mismatch between the dimensions and the speed.
5. Work without protection
You should not even approach the tool if it does not have a protective cover on it. The master himself must wear work gloves, goggles or a screen, as well as special work clothes. All of the above seems like trifles, but in reality, a few millimeters of fabric or plastic is often the fine line between a happy outcome and injury.
