sensitive elastic and plastic deformation and anelastic unrecoverable for spring work is extremely unfavorable. If found to these problems need to be replaced immediately spring. Hazardous residual solvent printing process. Secondly, the establishment of printing woven cutting and sewing machine maintenance regulations. Offset machine maintenance instructions shall prevail. Such as regular oil changes, cleaning filters, periodic testing machine precision. Finally, the machine requires maintenance machine fully into account when designing the machine maintenance convenience. However, due to the complexity of the printing press, to each of these factors are taken into account is clearly impossible, and the environment is changed, the content will change machine maintenance. So to those of the structure is not conducive to the maintenance of the machine to be improved without affecting the normal operation of the premise. (Bzdjx)
