Guard components are critical safety parts on power tools, shielding the user from blade or disc contact and containing debris. This part is sourced directly from DEWALT and is intended for technicians and service professionals performing tool repairs or safety-compliance restorations on DEWALT power tools. Proper guard function is non-negotiable for safe tool operation, making accurate part replacement essential.
The 90559429 SA guard is used in service and repair applications where the original guard has been damaged, worn, or lost. It is appropriate for shop technicians, tool repair facilities, and trade professionals who maintain DEWALT power tools in working order. Specific compatible tool models were not provided in the product data; refer to the DEWALT parts lookup or your tool serial number to confirm fitment before ordering.
Designed as an OEM-style replacement SA guard for compatible DEWALT power tools. Confirm fitment by cross-referencing the 90559429 part number with the specific tool model using DEWALT's official parts documentation.
Guard replacement should be performed by a qualified tool repair technician. Disconnect the tool from all power sources before beginning any disassembly or parts replacement. Follow DEWALT service documentation for correct guard mounting and fastener procedure. Do not operate the tool without the guard fully secured and verified.
