Do not use the grinder again until you have identified and fixed the problem. The most common cause of a smoking grinder is a bearing that has gone bad. To fix this problem, you will need to replace the bearing. You can also try cleaning the grinder's armature and commutator, which can sometimes help to reduce smoking.
• The grinder is not cutting properly. This can be caused by a number of things, such as dull blades, incorrect settings, or a problem with the gearbox. To troubleshoot this issue, first check the blades to make sure they are sharp. If the blades are sharp, then check the settings to make sure they are correct. If the settings are correct, then the problem may be with the gearbox. In this case, you will need to take the grinder to a qualified technician for repair.

Here are some additional tips for preventing problems with your Makita GA9020R:
