70 Class Machines Threading

THREADING
1) To thread the machine, follow the Threading Diagram – click on the machine style below to acces the online diagram – provided with each machine. A duplicate may be obtained upon request provided that the style and serial number of the machine is included with the request. The matter of threading is important and although simple, it must be accurate.

2) When threading the Looper Threads, it will be found convenient to use a threading wire. With the thread or yarn inserted in the eye of the threading wire, pass the wire through the thread eyes and tension discs as shown on the threading diagram. To place the Lower Looper in position to be threaded, turn the Hand Wheel until the Needle is in its highest position. Then, it will be possible to pass the threading wire through both the Lower Looper Thread Tube and the Lower Looper simultaneously.

3) The machine is ready to “chain” after threading the Needle or Needle and Looper as shown on the Threading Diagram.

4) It is generally advisable to keep tension on the thread as light as necessary to produce good results.
