Workplaces must be cleaned, mark the workpiece, only after you can start working.

The equipment must be held with both hands. If the wheel becomes jammed, the tool must not be pulled out of the hand. You should always be prepared for kickback, which can cause a lot of displacement. In general, kickback is one of the most dangerous moments in the operation of an angle grinder. In this case, a sharp sudden rejection of the tool occurs when the disc jams in the workpiece.

Basic cutting rules

When cutting a workpiece, it is important to make sure that you follow the basic rules. The cut line should pass by the person, but not rest against him. If the disc jams, the jet movement of the equipment will bypass the operator. It is important to provide protection with a casing. It must be placed between the worker and the circle.

It is not necessary to apply excessive pressure to the tool. The unit will be able to cope with tasks using its own weight. Whereas overloads will cause the circle to skew. The inclusion of the angle grinder is excluded when the disc is in the profile of the workpiece. Start cutting the profile from the place where the smallest cross section.

It is important to remember that when cutting tiles, concrete and stone, a lot of dust will be generated. Respiratory organs should be protected from it. Some manufacturers produce casings with a nozzle for a vacuum cleaner. You can also suppress dust with water, directing the jet into the cut. If you need to work on cutting a wall, you must be prepared for the fact that fittings, pipe or cable can get under the circle. This will certainly cause a backlash. To avoid injury, stay away from the equipment offset line.
