Connecting Machine to Power Supply

Before connecting the power supply, make sure the voltage and frequency shown on the machine conform to your electrical power.

Turn off the power switch, and insert the foot control plug 1, machine plug 2, into the machine and power supply plug 3 into the outlet in the following order.

1 Foot control plug

2 Machine plug

3 Power supply plug

4 Power switch

5 Power supply cord

6 Foot control

For Your Safety

* While in operation, always keep your eyes on the

		sewing area. Do not touch any moving parts such as
	3	the thread take-up lever, handwheel or needle.
		* Always turn off the power switch and unplug from the
		power supply:
		- When leaving the machine unattended
		- When attaching or removing parts
		- When cleaning the machine
		* Do not place anything on the foot control, when not
		sewing.
		Operating instructions
		For appliances with 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 it 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.
		Foot controller Model 21371 for use with Sewing Machine
		MC4800.
		Controlling Sewing Speed
		Speed setting lever
		The maximum sewing speed can be controlled by the
		speed setting lever. To increase the speed, slide the
		lever to the right (toward “	“).

To decrease the sewing speed, slide the lever to the left (toward “ “).

Foot control

Sewing speed can be varied by the foot control. The harder you press on the control, the faster the machine runs.

Note: The Memory Craft 4800 is equipped with a protective circuit to prevent overheating.

NOTE:

*In general, fine threads and needles are used for sewing fine fabrics, and thicker threads and needles are used for sewing heavy fabrics.

Always test thread and needle size on a small piece of fabric which will be used for actual sewing.

*Use the same thread for needle and bobbin.

*When sewing stretch, very fine fabrics and synthetics, use a blue tipped needle. The blue tipped needle effectively prevents skipped stitches.
