Using the Makita 9237C is easy. First, plug it into a 120V outlet. Use the variable speed dial and trigger to set the right speed for your job, whether it's automotive detailing or stone polishing. When starting, the soft - start feature will give you a smooth start. For continuous operation, press the lock - on button. When you're done, turn it off and unplug it. To keep it in good shape, regularly check the wire mesh intake cover and clean it if there's debris. Also, make sure to clean the externally accessible brushes when needed. When using the tool with the side handle, you can place it upside down on the rubber tool rest. Always be careful to avoid getting static electricity by using the 3 - prong plug. And don't forget to use the included pad alignment/centering sleeve for better results.
