Makita GA4550R Problems and Solutions

If the carbon brushes are worn down to the point where they are no longer making contact with the commutator, they will need to be replaced. To replace the carbon brushes, simply remove the old brushes and install the new ones. Make sure that the new brushes are the correct size and type for your grinder.
• The grinder is making a loud noise. This could be caused by a number of things, such as a worn bearing, a loose nut, or a damaged blade. To troubleshoot the noise, first unplug the grinder and let it cool down. Then, start the grinder and listen for the source of the noise. If you can identify the source of the noise, you can take steps to fix it. For example, if the noise is coming from a worn bearing, you will need to replace the bearing.
• The grinder is smoking. This is a serious problem and should be addressed immediately. Smoking can be caused by a number of things, such as a short circuit, a bearing failure, or a fire. If your grinder starts smoking, immediately unplug it and let it cool down. Do not use the grinder again until you have identified and fixed the problem.
