Dewalt 188579 Bracket Contact Arm

Product Description

The DEWALT 188579 is a replacement bracket contact arm designed for use in DEWALT power tools that rely on a contact trip mechanism. The contact arm assembly controls the actuation point of the nailer or fastening tool, engaging the driver mechanism only when the contact tip is depressed against a work surface. This part is typically installed by contractors, finish carpenters, and tool repair technicians performing preventive maintenance or restoring a tool to safe operating condition after component wear or damage.

This bracket contact arm is suited for repair and maintenance of DEWALT fastening tools that use a contact trip firing mode. It is most commonly replaced when the existing arm becomes bent, cracked, or worn to the point that the tool fires inconsistently or fails to actuate properly. Technicians replacing this part should confirm the specific tool model number against DEWALT service documentation to verify fitment before installation.

Installation Notes

Disconnect the tool from its power source and depressurize any pneumatic supply lines completely before disassembling the contact arm area. Refer to the applicable DEWALT service manual for the correct disassembly sequence and reassembly procedure.
