Notable features include an LED GripLight, HexGrip handle, integrated blower, and 50 degree bevel capacity. While the model is now discontinued, it remains compatible with RIDGID 18-V Li-ion slide-pack batteries. If researching repairs, check for typical wear items (brushes, switch, guard components) and confirm parts availability through third-party suppliers.

Always remove the battery before servicing or changing blades. Check for worn brushes and cracked guards during maintenance.
