Step 2: Connect the Main Frame. Secure the central support frame (Part 4) to one of the assembled base frames. Then, attach the main upright support (Part 3) and the upper converging arm support (Part 6) to the central frame using the appropriate hardware (Parts 15, 27, 32, 24). Insert the foam rollers (Part 14) onto the support bar (Part 13).
Step 3: Secure the Second Base Frame. Connect the second assembled base frame to the main central support using bolts and nuts (Parts 16, 32, 23, 34).
Step 4: Install Weight Plate Holders. Attach the weight plate holders (Parts 16, 32, 23, 34) to the sides of the main frame.
Step 5: Prepare the Bench Seat. Attach the adjustable bracket (Part 11) and the adjustment knob (Part 12) to the underside of the bench seat (Part 1) using the provided bolts (Part 20).
Step 6: Attach the Leg Extension/Curl Bar. Secure the leg extension/curl bar (Part 9) with its foam padding (Part 28) to the bench seat assembly using the pin (Part 22) and bolts (Parts 20, 32, 31).
Step 7: Mount the Bench Seat. Attach the assembled bench seat to the main frame of the machine using the pivot pin (Part 21) and secure it with the appropriate bolts and nuts (Parts 18, 32, 31).
Step 8: Install Converging Arms. Attach the left (Part 7) and right (Part 8) converging arms to their respective pivot points on the main frame. Secure them with the pins (Parts 19, 27) and ensure the handle grips (Part 37) are in place.

Operating Instructions
Adjusting the Bench
The bench can be adjusted to flat, incline, or decline positions to target different muscle groups. To adjust, locate the adjustment pin beneath the bench seat, pull it out, and reposition the bench to the desired angle. Ensure the pin locks securely into place before use.

Using the Independent Converging Arms
The independent converging arms provide a natural range of motion, mimicking free weights while offering the safety of a machine. Load weight plates onto the weight posts on each arm. Grip the handles firmly and push forward in a controlled motion. The safety spotter holders are designed to catch the arms if you cannot complete a repetition, enhancing user safety.
