How to Work Press Brakes & Bending Machines
Working a press brake or bending machine is common in industries like auto building or steel shaping. Although very useful, press brake machines can be dangerous if not properly operated, since they are designed to bend metal using tremendous amounts of pressure. Misuse can result in a crushed hand or other body part.

Ensure that the machine is not in repair and is in ready working order. A good lock out/tag out program should let you know when the machine is safe for use. Check the last inspection date to see if a recent one has been conducted within the appropriate time frame. Mechanical bending machines have many moving parts that could wear down over time and get stuck during the process. Hydraulic machines will require certain amounts of fluid and pressure for safe operation. If the last inspection is out of limits or reveals significant damage, do not try to work around it.

Clear the machine of any foreign objects before applying power. You don't want to make the instinctual mistake of trying to move something off of the press brake's surface while it's powered on. Your body could end up leaning on an actuating button or part, causing you great harm.

Adjust the machine to best fit your ergonomics. Your back should not bend too far over to use the press brake; nor should your arms have to extend so that your fingertips do all the piece placement and work. If possible, adjust the level of the machine or safely put yourself at the best ergonomic position to work. Standing on a cardboard box, for example, is not considered safe, whereas an approved metal step may do.

Wear all required protective gear and use all required safety equipment. Some machines may require safety gloves and glasses for operation. Other bending machines utilize light curtains to better separate the user from pinching points. If safety equipment is required and is not available, do not use the machine.

Operate the machine according to use and not for ease. If the press brake machine is for embossing but you use it for bending, the machine could be damaged or malfunction in a way to cause you harm. It's basically voiding a warranty that could not only hurt you but make you pay for any damages incurred.

Tips & Warnings
Many modern electronic press brake machines severely limit the operator's interaction with the pinching and moving parts. However, you still have to keep safety in mind while operating them.
Do not attempt to repair the bending machine while powered, regardless of the machine's condition. Failure to do so can cause great injury.
