Remove the bender handle from the lower frame by cutting the cable ties securing the handle to the frame. See Figure 1. Figure 3 3. Once the initial set-up is complete, the bender will require specific steps to accomplish various conduit bends. See Figure 4. Figure 1 2.

Pin Position: Three locations to insert retaining pin, which will produce different heights of offset bends. b. Offset Height Range: The range of offset height that this pin hole position will produce. (ie. 0-3⁄4", 0-2" and 0-3") c. Add to Height for Springback: The fraction with a plus sign indicates the amount to add to the offset height to correct for conduit springback.
