Using the Makita HM1502 is straightforward. First, make sure it's properly plugged in and the cord is in good condition. The L.E.D. power lights will let you know if there's a switch failure or cord damage. When starting the tool, use the Soft Start feature for a smooth start. The slide switch with lock - on is easy to operate without having to release the handles. For working in different positions, you can swivel the side handle 360°. When using it in dusty environments, consider getting the optional dust extraction kit. As for maintenance, keep an eye on the L.E.D. service light. It'll notify you about 8 hours before the brushes need replacement. The automatic brush cut - off protects the commutator, but still, make sure to check the brushes regularly. After use, store the tool in the provided blow - molded rolling tool case to keep it safe and ready for the next job.
