Using the RDB - 100 tubing bender is easy. First, when it arrives, it's mostly pre - assembled. Just attach the handle and the stand. Before you start bending, choose the right die set for your tubing or pipe. The bender can accept hundreds of different die sets for round and square tubing as well as round pipes. When bending, use the degree scale to quickly check your bend angle. The start - of - bend indicator line on the tooling helps you make precise complex bends. If you're working with lighter - gauge materials, you can use the manual override feature of the ratcheting bend system. When loading and unloading the material, the quick - release counter die system makes the process simple. As for maintenance, keep the bender clean and free of debris. Check the steel plate construction regularly for any signs of wear or damage. If you have any issues, you can contact our team for lifetime technical support. Remember, all capacities are based on A53 grade A (mild steel) 48,000 psi tensile materials. If you're using heavy wall or high tensile materials, it may reduce the machine's capacity. So, it's a good idea to consult Baileigh Industrial to review your material specifications. Also, tooling is not included, so call Baileigh at 920 - 684 - 4990 to get the correct sizing.
