Hydraulic stretcher must be operated strictly according to the method and procedure required in the instructions. The input working pressure and stretching length of the hydraulic stretcher can not be increased at will, so as to avoid damaging the sealing ring and the related mating parts.
After the hydraulic bolt tensioning tool is finished, it should be cleaned and kept properly. Especially, the oil inlet interface can not infiltrate into the ash, so as to prevent damage to the cylinder and piston after entering the cylinder.
When replacing O-ring and supporting ring of hydraulic bolt tensioner, attention should be paid to coincidence to ensure sealing effect.
