The Dual-Drive feature will continuously drive the socket as you swing the handle, regardless of which direction. To initiate this feature, just hold the dial on top of the ratchet head still. The Speed Ratchet feature will drive the nut or bolt at a 2 to 1 ratio. To use this feature, simply hold the handle still whilst turning the dial on top of the ratchet back-and-forth quickly. For every full rotation of the dial the bolt turns twice.
