What should I do if my unit is overheating? If your Sun Joe Scarifier Dethatcher is overheated, allow the unit to cool for up to 60 minutes. Clean any grass-clogged air vents with a fine-pointed swab, and raise the dethatching height to allow for more air flow and to ensure that the unit is not being overworked. If you are still having issues, please reach out to our customer support team for assistance. Related articles The motor does not run. Why won't my CJ602E restart?
