A045 Presser Foot Lifter Set Complete for GK9 Portable Bag Closer

The A045 Presser Foot Lifter Set Complete is a direct replacement assembly designed for the manual presser foot lifting mechanism found on GK9 portable bag closer machines. This complete kit restores smooth lifting and lowering of the presser foot, making it easier to position bags, align materials, change thread, and remove finished sacks after stitching.

This all-in-one replacement includes the lifting lever, mounting pivot pin, and internal lifting cam components required to replace a worn, loose, or damaged presser foot lifting mechanism. It is engineered for standard GK9 portable bag closer machines, making installation straightforward without modifying the machine.

Whether you repair packaging equipment or operate a bag stitching machine daily, replacing a worn presser foot lifter helps maintain smooth operation and consistent handling of packaging materials.

Complete Replacement Assembly

Instead of replacing individual worn components, this complete set provides everything needed to restore the presser foot lifting system.

The assembly includes:

• Presser foot lifting lever
• Internal lifting cam
• Pivot pin
• Matching lifting mechanism components
• Complete ready-to-install assembly

This reduces installation time while restoring proper lifting action.

Designed for Easy Manual Operation

The high-leverage lifting mechanism allows operators to raise the spring-loaded presser foot using minimal effort.

Its ergonomic design helps during:

• Bag loading
• Material alignment
• Thread replacement
• Cleaning around the needle area
• Removing completed stitched bags

The smooth lifting action improves daily operation, especially during continuous bag closing work.

Secure Raised Position

A precision-machined locking detent keeps the presser foot securely raised when required.

This hands-free raised position makes it easier to:

• Insert thick bags
• Reposition packaging materials
• Replace sewing thread
• Inspect stitches
• Perform routine maintenance

The mechanism helps improve operator convenience while reducing unnecessary handling.
