Automatic shutdown due to cooling fan fault

It may be the case that your PLANEX Drywall Sander turns off due to the electronic fan. To ensure proper air circulation, the vents on the handle of the PLANEX Drywall Sander must always be kept clean and clear.


Clean the vents with an extractor or a brush (Note: Do not clean with compressed air). Turn the tool back on.


If the problem occurs again, please contact the Festool customer service.
