Using the Jet JSG-6DC Sander is a breeze. First, plug it into the appropriate voltage (it can be set to 115V or 230V). Before starting, make sure the belt and disc are properly installed. You can adjust the belt tracking using the dual thumbscrew or the tracking adjustment knob with the quick - lock handle. For different sanding angles, use the precision - ground cast iron tables with positive stops at 90° and 45°. When changing the belt, use the quick - release belt tension lever. And for disc changes, the quick - lock dust cover makes it fast. As for maintenance, regularly clean the dust port at the back of the base to keep the dust collection effective. Also, since the graphite - covered steel platen runs cooler, it's important to check its condition over time. Remember, the rubber - coated drive drum provides a better grip on the belt, so look out for any signs of wear. Always follow safety guidelines and turn off the machine before making any adjustments.
