Puller

Functions:

Automatic raising puller is associated with three cases:

• Sew foot lift

• Start/End backtack

• Reverse

When the sewing foot is lifted, the puller is automatically rised, when the foot is lowered, the puller is also lowered.

During the sewing the start/end backtack, the puller is automatically raised, once the start/end backtaak is complete, the puller is also lowered.

When manual reverse button is pressed, the puller is automatically raised, once the reverse is turned off, the puller is also lowered.

An input port can be configured to switch between raising and lowering the puller. When the key is pressed to raise the puller, it will remain raised until the key is pressed again to lower it.
