2. Constructions and Operation
1.ConstructIons
The kneader blade attached to the inner pot ass’y is rotated by the main motor by way of the pulley and
the belt. The ingredients inside of the inner pot are kneaded by the kneader blade. The inside of the
temperature is controlled by the thermal sensor and the heater between the processes of “kneading”
and “baking” .—

●Description of operation
(1) VDD-VSS Power supply (5V)
The secondary output of power transformer(PT101 )is given bridge-rectification by the diode
(D101 -D104) and the condenser (C107) to produce 13V voltage at@. The voltage at@is used to
compose@ 5V power supply by the operation of constant voltage circuit consisting of 3-terminal
output voltage regulator (ICI 01).

●Description of operation
(1) Heater control circuit
When the voltage at pin 13 of the micro computer (ICI) becomes Low (OV), the signal will drive
transistor (QI 05), transistor (Ql 03), Photo triac (PH101 ), and thentriac(TAC101 )to operate the
heater,
(2) Motor control circuit
When the voltage at pin 14 of the micro computer (IC1)becomes Low (OV), the signal will drive
transistor (Q104), transistor (Ql 02), Photo traiac (PH102), and thentriac(TAC102) to operate the
motor.

7. Disassembly Procedures
1. Disassembly of lid
(1) The lid ass’y can be dismounted while the lid open and pulling upward.
(2) The window, holder (window) and air window can be dismounted by removing tab of lid fixing frame.
(Fig. 1)
2. Disassembly of main unit
/(1) The bottom lid can be dismounted by removing 4fitting screws and 4 stands on the bottom lid.
(2) Removing the fitting screw on the rear and left side of control panel. The control panel can be
removed from the main unit by removing tab of control panel out of cabinet, through pressing
rightward on the rear surface of control panel. The control panel can be dismounted by removing
detached 2sockets from the control PCB ass’y.
(3) The control PCB ass’y can be removed from control panel by removing the 3fitting screws and tab
of control panel.
(4) Removing the 3fitting screws of the terminal. And removing the power cord ass’y can be
dismounted from the main unit by loosen the fasten screw of the cord bushing.
(5) The main unit can be pulled up after removing 6fitting screws of inner cabinet (U), and the main unit
and hinge can be separated out of cabinet. (Fig. 2) The cord bushing can be dismounted by
removing the net of the cord bushing from the cabinet.
(6) Cut the 3fixers that hold the lead wire. Then, remove the following sockets: socket from the motor,
socket from the heater, socket from the fuse ass’y, connector from the motor and connector from the
two lead wires.
(7) The power PCB ass’y can be dismounted by removing the fitting screw of power PCB ass’y and
fitting screw of support. (Fig. 3)
(8) The capacitor can be dismounted by removing the fitting screw. (Fig. 3)
(9) By removing the 3motor fitting screws,

(10) The pulley (big) and holder can be dismounted by removing the pulley (big) fitting ring. (Fig. 4)
(11)Removing the fitting screw on the eafih read wire 65L of the chassis side. Removing the two lead
wires 155L, the earth lead wire 65L and two Ceramic Capacitor, fixed on the terminal. By removing
the terminal fitting screw, the terminal and the sheet can be dismounted.
(12) The power cord can be taked off by removing the cord bushing from chassis.
(13) The inner cabinet ass’y can be removed by removing the 3fitting screws of the holder (base) ass’y,
and setting tab of the shield to its horizontal position. (Fig. 3)

fitting nut and the insulator Afitting hook@ of inner cabinet (M), the heater ass’y and insulator A
can be dismounted from the inner cabinet. (Fig. 5)
By removing the fitting screw of the holder (heater), the holder (heater) and the insulator can be
dismounted from heater ass’y. (Fig. 5)
The fuse unit can be dismounted by removing the screw inside of the inner cabinet which is fixing
the fuse unit. The fuse ass’y can be removed by straightening the fixing tab of the holder (fuse).
(Fig. 5)
The sensor ass’y and the holder (sensor) can be dismounted by removing the screw inside of the -
inner cabinet which is fixing the sensor ass’y. (Fig. 5)

(19) The spring plate can be taken out by removing its fitting screw.
(20) The joint ass’y, the holder (base) and tube can be dismounted by removing the holder (base) fitting
ring,
Precautions for Reassembly
(1)When mounting the power cord, the cord bushing should be attached to the cord holder so that the
dimensions between the bushing and the top of the terminal is approx. 25 mm. (Fig. 6)
(2) Wiring should be made as shown in the specified wiring diagram. (Fig. 6)
