Dewalt has officially recalled about 1,364,000 12″ sliding miter saws in the USA, and about 118,600 units sold in Canada.
This recall affects Dewalt DWS779, DWS780, and DHS790 12″ sliding miter saws that were sold from April 2019 thru May 2022.
According to the US CPSC recall notice, Dewalt has received 571 reports of the blade guard assembly breaking or detaching. There were 9 reports of laceration injuries.
Dewalt’s notice says:
The plastic rear guard assembly can break/shatter when struck, exposing the saw blade and posing a laceration hazard.
Consumers are advised to immediately stop using the recalled miter saws and contact Dewalt for a free repair kit. Alternatively, you can take affected saws to a Dewalt service center for a free repair.

To determine whether your saw is affected, refer to the date code, which is located on the nameplate (DWS779, DWS780) or battery mount (DHS790).
Dewalt date code format is 20XX YY-ZZ, with 20XX being the year, YY being the week of manufacture, and ZZ being a plant code (CJ or 49).
Affected date codes are numbered 2019 04 through 2022 04.

If your saw has a green or black dot next to the serial number or on its frame in the designated location, it has already been inspected and is not affected by the recall.
Recall Number: 22-196
Contact Dewalt at 800-990-6421 from 8am to 6pm ET Monday thru Friday.
Dewalt’s recall notice also has a web form for repair kit requests.
Dewalt issued a stop sale for the same miter saws in June, and so this recall has been anticipated.
Thank you to Pete for bringing this to our attention!
