Using the Jet JWDS - 1020 benchtop drum sander is easy. First, plug it into a 115 - volt power source. Then, adjust the conveyor speed according to the type of wood and the sanding task using the variable - speed control. Place your board on the precision - flattened conveyor bed and make sure it's properly aligned. Start the machine and let the conveyor system pull the board through the sander. Remember, the maximum board width is 20 inches and the maximum thickness is 3 inches. When it comes to dust collection, connect the 4 - inch dust port to a dust collector with at least 550 CFM. This will keep your workspace clean. As for maintenance, check the abrasive regularly and change it when it gets worn out. You can do this quickly with the toolless abrasive take - up fasteners. Also, keep an eye on the motor. The control system has a circuit breaker to protect it from overheating, but it's still a good idea to let the sander cool down after long - term use. Lastly, be aware that this product has a Prop 65 warning about cancer and reproductive harm, so take necessary precautions.
