Assuming that the selected pipe bender is the correct choice for bending the required diameter of pipe, the first thing to check is the hydraulic fluid level in the cylinders. Hydraulic leaks due to any broken, cracked, bent or missing parts may compromise the safe operation of the machine. Users should also make sure that the power cord, plug and other electrical components are in a good state. They should also check if the appropriate bending forms are used & supports are placed in symmetrical holes. Finally, grease should be added on the side of the corner bracket for reducing abrasion related damages on contact with the pipe.
