 CAUTION
When leaving this sewing machine unattended, the main power and light switch of the machine must be
switched off or the plug must be removed from the socket-outlet.
When servicing the sewing machine, or when removing covers or changing the light bulb, the machine or
the electrical set must be disconnected from the supply by removing the plug from the socket-outlet.
FOR USERS IN THE UK, EIRE, MALTA AND CYPRUS ONLY.
If your sewing machine is fitted with a 3 pin non rewireable BS plug then please read the following.
IMPORTANTIf the available socket outlet is not suitable for the plug supplied with this equipment, it should be cut off and an
appropriate three pin plug fitted. With alternative plugs an approved fuse must be fitted in the plug.
NOTEThe plug severed from the mains lead must be destroyed as a plug with bared flexible cords is hazardous if engaged in
a live socket outlet. In the event of replacing the plug fuse, use a fuse approved by ASTA to BS 1362, i.e. carrying the
ASA mark, rating as marked on plug.
Always replace the fuse cover, never use plugs with the fuse cover omitted.
WARNING
DO NOT CONNECT EITHER WIRE TO THE EARTH TERMINAL WHICH IS MARKED WITH THE LETTER
E, BY THE EARTH SYMBOL 
 OR COLOURED GREEN OR GREEN AND YELLOW.
The wires in this mains lead are coloured in accordance with the following code:
Blue: Neutral
Brown: Live
As the colours of the wiring in the mains lead of this appliance may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows.
The wire which is coloured blue must be connected to the terminal which is marked with the letter  N  or coloured
black or blue.
The wire which is coloured brown must be connected to the terminal which is marked with the letter  L or coloured red
or brown.

CONGRATULATIONS ON CHOOSING THIS COMPACT
OVERLOCK MACHINE
Your machine is a high quality, easy-to-use product. To fully enjoy all the features, we suggest that you
study this booklet.
If you need more information regarding the use of your machine, your nearest authorized dealer is always
happy to be of service.
Enjoy yourself!
 CAUTION
When threading, replacing needle or light bulb, the main power and light switch of the machine must be
switched off or the plug must be removed from the socket-outlet.
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 foot-operated 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
normal operation.

bottom right side of the machine. Insert the power
supply plug into a power outlet.
2. Turn the main power and light switch  to I mark
(to O mark to turn off).

Operation
When the foot controller is pressed lightly, the machine
runs at a low speed. As the foot controller is pressed
further, the machine will increase speed. When the foot
controller is released, the machine stops.
NOTE (For U.S.A. only):
Foot controller: Model KD-1902
This foot controller can be used for sewing machine
models 3034D.
Turning direction of hand wheel
The hand wheel  turns in a counterclockwise
direction (direction of arrow). This is the same direction
as an ordinary home sewing machine.
The needles move to their highest positions by turning
the hand wheel so that the mark  on the hand wheel
is aligned to the line on the machine.
 
Opening/ Closing front cover
It is necessary to open the front cover when threading
this machine. Slide it to the right 1 and open 2, or
close it and slide it to the left.
