Small angle grinders are power tools that we often use in our daily lives, but we usually ignore the maintenance of angle grinders, so I remind everyone that they also need maintenance during use.
1. Frequently check whether the power cord is firmly connected, whether the plug is loose, and whether the switch action is flexible and reliable.
2. Check whether the brushes are too short of wear, and replace the brushes in time to prevent excessive sparks or burning of the armature due to poor contact of the brushes.
3. Pay attention to check that the inlet and outlet of the tool should not be blocked, and remove the oil and dust from any part of the tool.
4. Grease should be added in time.
5. If the tool fails, send it to the manufacturer or the designated maintenance center for repair. If the tool is damaged due to abnormal use or man-made wrong disassembly and repair, the manufacturer generally does not repair or exchange it free of charge.
6. Check the mark of the angle grinder. Angle grinders that cannot be used include: unmarked, unclear markings, unverifiable, regardless of defects.
7. Check the shortcomings of angle grinders. There are two kinds of inspection methods: visual inspection, directly observing whether there are cracks on the surface of the angle grinder with eyes; percussion inspection, which is the inside of the main angle grinder to be inspected, and the method is to hit the angle grinder with a mallet. If there is no problem with the angle grinder, it should be a crisp sound, if it is other sound, it should be a problem.
8. Check the rotation strength of the angle grinder. The same type of angle grinders of the same batch of models are used for random inspection of rotation strength. Angle grinders that have not been tested can never be installed and used.
