Using the Jet 723950 Oscillating Spindle Sander is straightforward. First, make sure it's properly plugged into a 115V power source. You can adjust the table tilt according to your needs, up to 45° forward and 15° backward. When changing spindles, use the spindle lock for a quick and easy swap. Connect the 4 - inch dust port to your dust collection system to keep your workspace clean. For safety, always use the paddle switch with the safety key. When it comes to maintenance, regularly check the dust collection chamber under the table and clean it. The sealed access door to the storage area helps keep dust out, but it's still a good idea to clean the storage periodically. Also, keep an eye on the motor, which is independently mounted in the base for easy access if servicing is needed. The oscillating action reduces heat, but overheating can still occur with extended use, so give the machine breaks when doing long sanding jobs.
