Connecting Machine
Before plugging in your machine, be sure that
the voltage and number of cycles Indicated on
the electrical nameplate A conform to your
electrical power supply.
If your speed controller cord has a motor
disconnect plug, push plug B into the receptacle
at the right end of machine. Then connect plug
C to your socket outlet.
If the speed controller cord is wired directly to
the motor, simply connect plugC to your
socket outlet.
CAUTION: Disconnect the power line plug
from the socket outlet when changing needles,
feet, or needle plates or when leaving the
machine unattended. This eliminates the
possibility of atarting the machine by
accidentally pressing the speed controller.
If your machine has a sewing light switch, press
or turn switch on the machine, as required.
If machine has a three-position switch”
• The OFF setting (switch moved to 0
symbol).
• The MIN. setting (switch moved to —
symbol) allows the maximum control for
special jobs.
• The MAX. setting (switch moved to =
symbol) allows for full speed capacity of the
machine.
To run the machine and control speed, press
the speed controller D with your foot. The
harder you press, the faster the machine will
sew. To stop machine, remove foot from
controller.
CAUTION: Because of the up and down
movement of the needle, you must work
carefully and watch the sewing area when
operating the machine.
