Setting Up the Thread Guide Holder
POLARIZED PLUG INFORMATION (FOR U.S.A. & CANADA ONLY)
This appliance has a polarized plug (one blade wider than the other). To reduce the risk of
electric shock, this plug is intended to fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified
electrician to install the proper outlet. Do not modify the plug in any way.
Warning:
* Be sure that the electrical voltage of the electric outlet (wall receptacle) is the same as the rated
voltage of the motor.
* Handle the foot controller with care and avoid dropping it on the floor. Be sure not to place
anything on top of it when not in use.
* Disconnect the power line plug from the electric outlet when changing needles, presser feet or
throat plates, or when leaving the machine unattended. This eliminates the possibility of starting
the machine by accidentally pressing the controller.
This machine is shipped with the thread guide holder
in the lowered position.
Fully extend the thread guide holder.
The two joints on the telescope will click into place
when they are correctly positioned.
Center the thread guides above the spool pins.
Place thread over the cone adapters on the spool
pins.
Note: If the machine is threaded, straighten the
threads to prevent tangling.
