2. To protect against electrical shock, do not immerse cord, plug, or appliance in water or other liquid.
3. Do not touch hot surfaces. Always use oven mitts when handling the hot bread pan of bread.
4. Close supervision is necessary when the appliance is used by or near children.
5. Unplug the unit from the outlet when not in use and before cleaning. Allow the breadmaker to cool before attaching or removing parts.
6. Do not touch moving parts.
7. Do not operate the appliance with a damaged cord or plug or after the appliance malfunctions, or it has been dropped or damaged in any manner. Return the appliance to the nearest authorized service facility for examination, repair, or mechanical adjustment.
8. Attachments that are not recommended or sold by the appliance manufacturer should not be used.
9. Do not use outdoors.
10. Do not let the cord hang over the edge of the table or counter or touch hot surfaces.
11. Do not place on or near a gas or electric burner, or in a heated oven.
12. To disconnect, grip the plug and pull it out from the wall outlet. Never pull the cord.
13. Do not use the appliance for other than the intended use.
14. This product is intended for household use only.

2. SERVICING PRECAUTIONS

The following cautions should be observed when troubleshooting.

a) As the appliance is made to be serviced only by properly qualified service personnel, it cannot be repaired by the user.
b) Before servicing, you should keep your hands dry. The power cord must be unplugged to protect electrical hazards.
c) Wear gloves when assembling or disassembling the appliance to avoid being injured by a sharp edge.

3. INSTALLATION INSTRUCTIONS

a) Place the breadmaker allowing at least 4-inch air space around sides and top of the breadmaker.
b) Always place the breadmaker on a heat-proof counter top or table during operation.
c) This breadmaker must be placed on a firm, flat, and solid surface.
d) 120/60Hz reted bread Machine has a polarized plug; one blade is wider than the other. 230V/50Hz rated bread Machine has to be earthed.
e) Extension cords are available and may be used if care is exercised in their use.

EXTENSION CORD IS USED

1. The marked electrical rating of the extension cord should be at least as great as the appliance.

2. The longer cord should be arranged so it will not drape over the counter top or tabletop where it can be pulled by children or tripped over.

2) When constant pressure is applied to the pad, the time will advance quickly from 4:10 to 13:00.
3) After 13:00 is set, press once more, then the REMAINING TIME displays 4:10.
4) If you pass the time that you wanted, press TIMER DOWN PAD (▼) to go back.

(f) After selecting PROGRAM SELECT and BAKING CONTROL, press the START pad. Then the colon on the REMAINING TIME blinks to indicate that the breadmaker starts to operate.
(g) Press the CANCEL(STOP) pad to cancel all baking processes. If the START pad is already pressed, just press the CAN-CEL(STOP) pad and hold for MORE THAN 1 SECOND.

CAUTION

1. The TIMER can not be used in CAKE AND JAM.
2. After setting the time, press the START pad to operate the breadmaker. Check to see if the colon blinks.

1. TEST KEY PROGRAM CHECK

You can check the operating of each load by using the self-diagnosis program.

(a) OPERATION CHECK

1) When power is supplied while pressing the TIMER UP PAD (▲) and TIMER DOWN PAD (▼) at the same time, the self-diagnosis program will start.
2) After checking 1), press the START pad, then the process will advance as follows.

REMAINING TIME display	18:00	P:1	P:2	18:00 → P:1 →
OPERATION	LED CHECK	Kneading motor	Heater	......

3) After 60 seconds from the starting points of processing, or if the CANCEL(STOP) pad is pressed, the self-diagnosis program will be canceled.

(b) BAKING PROCESS CHECK (for the only Russian Cook)

1) When power is supplied while pressing the START pad and CANCEL(STOP) pad at the same time, the self-diagnosis program will start.
2) After checking the REMAINING TIME (IR displayed with beeps), press the START pad.
3) The breadmaker starts to operate and the baking process will advance as followsl.

The temperature is controlled at 25°C (77°F).

Breadmaker starts to operate intermittently to proof flour splashed for 2 minutes. After mixing flour with water, kneading blade rotates with 250rpm for 5 minutes. After resting for 23 minutes, rotation again for 12 minutes. During knead and rest courses, the temperature is maintained at 30°C (86°F) by using the sensor and heater.

Accurate temperature control is essential during rising, (Dough temperature: Approx. 36°C (97°F). Microcomputer controls the power supply accurately to keep suitable dough temperature.

Bread is baked with high power. Bread is baked with a crisp golden crust and a fluffy inside.

Immediately after baking, bread can not be eaten because it's too hot.

Breadmaker maintains the bread at a suitable temperature (60°C/140°F) for 3 hours.

DISASSEMBLY INSTRUCTION

• PAY ATTENTION TO THE FOLLOWING IN SERVICE AND INSPECTION.

(a) Protect against electric shock: Pull out the plug for service and inspection. Don't touch live components when service and inspection are made.
(b) Restore the original conditions of components and wire layout; Safety provisions are made by using tube and the other insulation material and by preventing wire from contact with heat generating or movable components by means of layout and binding. They should be restored to the origina conditions.
(c) Safety inspection after service is required as follows: confirm that screws, nuts, components, and wires removed for service are restored. Check the deterioration around service components, and check for insulation.

1. Turn the Top Cover assembly upside down and pull out the inner cover and the viewing window.
