Dual Feed System (Dfs); To Engage The Dfs System - Pfaff C1100 Pro Owner's Manual

DUAL FEED SYSTEM (DFS)

The DFS system feeds fabrics from the top and bottom simultaneously, ensuring that the fabric
layers feed evenly. Use this when sewing checked, striped or plaid fabrics, as well as quilt layers.
It is also helpful when sewing lightweight or difficult-to-handle fabrics such as silk or rayon, as the
DFS system prevents puckering.

To engage the DFS system

Attention: Only use presser feet with the back opening when engaging the DFS
mechanism .
Raise the presser foot.
Lower the DFS mechanism slowly.
Swing the DFS mechanism forward under the
back of the presser foot until it is engaged and
stays in the lowered position.
