Makita GA5040C Problems and Solutions

To clean the air filter, remove it from the grinder and blow it out with compressed air. If the filter is severely damaged, replace it. To check the carbon brushes, remove them from the grinder and inspect them for wear. If the brushes are worn down to less than 1/4 inch, replace them. To check the belt, make sure that it is properly seated and not damaged. If the belt is damaged, replace it.
