Instructions for operating 3801(E), 3802(E), 3811(E), 3812(E), 3813(E), 3814(E) pipe benders, including tool assembly, bending operation, and straightening operation.
The RIDGID bend tube machines (models 3801(E) through 3814(E)) are hydraulic tools for bending pipes of various diameters up to 180°. They are powered by single‑phase (115 V or 220 V) or three‑phase (380 V) motors and include safety features such as a pressure valve.
The manual covers safety notices, step‑by‑step assembly, bending procedures, regular maintenance, a detailed parts list, accessories for 180° bends, troubleshooting tips, and warranty information. Users are instructed to follow the safety guidelines, check hydraulic oil level, and use the correct bending dies for the pipe size. This manual is written in Chinese.
