When the machine is not in use, it is recommended that the electric supply plug is disconnected from the wall socket to avoid any possible hazards.

Notes on the motor

-The maximum operating speed of this sewing machine is 1,300 stitches per minute, which is quite fast compared to the normal operating speed of 300 to 800 stitches per minute for the ordinary sewing machine.

-The bearings in the motor are made of a special sintered, oil-impregnated alloy mounted in oilsoaked felt to withstand long hours of continuous operation.

-Continuous operation of the sewing machine can cause heat to build in the motor area, but not enough to adversely affect its performance.

It is important to keep fabric and paper away from the air openings on the back and sides of the machine so air can get to these openings.

-When the motor is running, sparks can be seen through the air openings in the motor bracket on the side opposite the hand wheel. These sparks are produced by the carbon brushes and the commutator, and are part of the machines normaloperation.

Differential feed

This serger is equipped with two sets of feed dogs under the presser foot to move the fabric through the machine. The differential feed controls the movement of both the front and the rear feed dogs. When set at 1, the feed dogs are moving at the same speed (ratio of 1). When the differential feed ratio is set at less than 1, the front feed dogs move slower than the rear feed dogs, stretching the fabric as it is sewn. This is effective on lightweight fabric that may pucker. When the differential feed ratio is set at greater than 1, the front feed dogs move faster than the rear feed dogs, gathering the fabric as it is sewn. This function assists in removing the rippling when serging stretch fabrics.

1 Less than 1.0 2 Greater than 1.0 <A> Selection mark

An example

When stretch material is sewn without using the differential feed, the edge will be wavy.

English

To get smooth finish, adjust the feed ratio from 1.0 toward 2.0.

(The feed ratio required depends on the elasticity of the material.)

The more elastic the material, the further toward 2.0 the differential feed ratio should be set. Test sew with a scrap of the fabric to find the correct adjustment.

CAUTION

When sewing thick non-stretchable material such as denim, do not use the differential feed as it may damage the fabric.

Adjusting the presser foot pressure

Turn the pressure adjustment screw on the top left of the machine. You can adjust by reffering the value on the screw.

The normal setting is "2".

Tension adjustment dial

There is a thread tension dial for each needle thread, the lower looper thread and the upper looper thread. The correct thread tension may vary according to the type and thickness of the fabric and the type of thread used. Thread tension adjustments may be necessary for any change in sewing materials.
