Assuming that the selected drill press is supplied with the correct power supply and is the correct choice for the desired hole size, the first thing to check is the status of the wiring connections. Users should also check & clean dirt or dust accumulated on the motor causing heating up of the motor. Motors, step pulley & belt drive should also be lubricated regularly for smooth operation. Users should take care that they do not run the drilling machines in a workpiece not suitable for drilling according to the product's operating manual. They should also check for wear & tear on the drill press parts.
