Operation Guide

1. Connect the electric pump to a grounded power supply (voltage per nameplate).
2. Tighten the release valve (clockwise); loosen the vented oil bolt.
3. Grease the die cover, swagging blocks and the pipe to be bent.
4. Lift the upper plate and fix the correct bending die to the cylinder ram end.
5. Turn the swagging blocks so the grooves face the pipe die; set them for the pipe length.
6. Start the pump and apply hydraulic pressure to bend the pipe to the desired angle (max 90°).
7. Release pressure by opening the release valve; the ram retracts automatically; lift the upper plate and remove the bent pipe.
