Any device ever fails. And to delay this, you need to properly handle the Metabo grinder. When working with the device, you should periodically carry out a technical inspection, clean and lubricate the grinder inside. If during the operation of the tool there are interruptions in work, you should stop the machine and identify the cause. Before disassembling it, check the integrity of the power cord, if your grinder has one. It often bends and breaks inside.

If the wire is intact, then you should pay attention to the trigger mechanism itself. Often the start button becomes greasy and clogged with dirt. It can be simply removed and washed, and in extreme cases replaced with a new one.

But it is not always possible to fix the device yourself. There are some breakdowns that only a professional can handle, for example, your device needed to change the gearbox bearing or the gear in the head needs to be replaced.In this case, it is better to hand over the angle grinder to a service center, where highly qualified specialists will carry out a complete diagnosis of the device and replace worn parts, especially since the authorized Metabo services have a fairly developed network in our country.

• Work in overalls and glasses. Sparks and abrasive particles can bounce off and injure you, so protection should not be neglected.
• Do not remove the cover from the grinder without special need during operation. It will also protect you from serious injury in the event that the disc breaks apart.
• Do not cut the chipboard with this tool. Use a saw or hacksaw for this material.
• Hold the device firmly during operation. If the disc is jammed, the tool may fall out of your hands and harm your health.
• When working, do not under any circumstances speed up the process by pressing on the processing material. You only need to apply force to the instrument itself, and even then it is insignificant.
