Preparation before threading

When doing preparation before threading, turn off the machine for safety.

Thread tree

Raise the telescoping thread tree to its highest position. Make sure that the thread holders are in alignment above the spool pins as illustrated below.

Thread spool

 

Using the thread spool cap

 

When using sewing thread spools, the thread spool cap should be used as illustrated below.
Make sure that the spool notch is on the bottom.

  • If the thread spool cap is not fully pushed down, the thread may become entangled on the spool pin or the needle may bend or break.

 

Spool mat

 

When using thread spools or loosely spun thread that easily slips off the spool, place this mat under the spool.

This prevents the thread from becoming entangled on the spool pin.

Using the spool mat

 

  1. Remove the spool cushion, and then place the spool mat on the spool pin.
  2. Place the thread spool (with the spool notch at the bottom) on the spool pin, and then place the thread spool cap on top and fully push it down.

    If the thread spool cap is not fully pushed down against the thread spool, the thread may become entangled on the spool pin or the needle may bend or break.

 

 

Using the thread net

 

If you are sewing with loosely spun nylon thread, we recommend that you cover the spool with the included net in order to prevent the thread from slipping off the spool.
Adapt the net to the shape of the spool.
