PFAFF coverlock 4852 Owner's Manual - 2004 Edition
The PFAFF coverlock 4852 is a high-performance household sewing machine engineered with advanced overlock and cover stitch capabilities to manage diverse textile densities. Reliability and equipment uptime are significantly enhanced by the requirement for EL X 705 (Category No. 2002) needle systems, which are specifically designed to prevent skipped stitches and needle deflection during high-speed operation.
