3）Check the mandrel, the stopper, and the turntable of Steel bar bending machine should be free from damage and cracks, and the protective cover should be fastened and reliable, and the operation can only be performed after the empty machine is running normally.
4）During operation, insert one end of the steel bar that needs to be bent into the gap provided by the turntable, and the other end is tightly fixed against the body and pressed by hand to check the fixation of the body.It can be moved only when it is installed on the side that blocks the steel bars.
5）It is strictly forbidden to replace the mandrel, change the angle, and adjust the speed during the operation, and do not add oil or remove it.
6）When bending steel bars, it is strictly forbidden to process steel bars that exceed the diameter, number of bars and mechanical speed specified by the steel bar bending machine
7）When bending high-hardness or low-alloy steel bars, the maximum limit diameter should be changed according to the mechanical nameplate, and the corresponding mandrel should be exchanged.
8）It is strictly forbidden to stand on the side of the fuselage that is not fixed within the working radius of the bent steel bars. The bent semi-finished products should be stacked neatly, and the hooks should not face upwards.
9）When the turntable changes direction, it must be done after stopping.
10）The work is completed, the site is cleaned, the steel bar bending machine is maintained, and the lock box is powered off.
