It may be the case that your PLANEX Drywall Sander switches off automatically due to overload. In this case, switch the PLANEX Drywall Sander off and leave it to cool down for approx. five minutes. You can help it cool down by leaving the machine to run idle, allowing the accumulated heat to escape.

If the problem occurs again, reduce the application pressure or suction power and/or clean the vents on the sanding head.

If the problem persists, please contact FESTOOL customer service.
