WORK PRINCIPLE INSTRUCTION
I. Time part
1. The extro force will make 7(main shaft), 4, 6(cam) and 37(first cam) rotate clockwise to a certain angle, then
43(spring) transmogrify and accumulate power, the both sides of 48, 49(reed) be contacted, move limitation of
8(sway slice) was released. When the force is released, 8(sway slice) swift by constant frequency. After gear
move by variety speed, 43(spring) mode 7(main shaft) can only rotate back by constant velocity.
2. A moment later, the gap in 6(buzzer cam) reach 46(adjustor), the 47, 48(reed) be contacted, begin to buzz, the
gap in 4 (main cam) reach 44(adjustor), the main circult disconnect, the movement of 8(sway slice) is limited,
cease to buzz, the timer stop working.
II. On, OFF part
15, 33(program cam), 21, 32(adjustor) move along with the surface of program cam, 22, 31(reed) swing with its
elasticity so as to ON and OFF freely.
III. Conversion part for strong, medium, weak.
When exact force add to 29(reversion shaft) 30(the program reversion panel) will glide by horizontal, due to the
three stage strong, medium, weak designed on the 30(program reversion panel), the 20(shaft cover) move by
vertical, which made 21, 32(adjustor) move by horizontal so that there will by three rate strong, medium, weak
can be chose 15, 33(program cam).

FUNCTION
The spin timer is the switch providing power to the SPIN MOTOR(DRAIN PUMP MOTOR) during the set spin dry
time, and is a spring-type time switch comes on turning and those contact points comes off after the set time.
STRUCTURE AND PRINCIPLE OF ACTIVATION
1) The main shaft turns due to the unwinding force when the spin timer is turned, the spring wound with that force
being delivered through each gear and the spring slowly unwinding at a speed finally controlled by the angle
assembly.
2) The contact point Turns ON and the assembly angle is set in motion which is in the CAM groove in the OFF
state, comes off the groove when the main shaft is turned to wind the spring. The contact point turns OFF,
return to CAM groove when the spring unwind completely.
SAFETY DEVICE FOR BASKET SPIN
The BASKET SPIN is an apparatus which eliminates the water from the laundry through centrifugal separation
generated by rapid revolution(approximately 1,700rpm for 60Hz). Accordingly, there are a DOOR SWITCH to cut
off the power going into the DOOR SPIN is opened and a brake system to stop the rotating BASKET SPIN.
DOOR SWITCH
When the DOOR SPIN is opened during spinning, the DOOR
SWITCH LEVER which sites atopt the DOOR SPIN falls off the
contact, and cuts off the power going into the SPIN MOTOR.

BRAKE SYSTEM
When the DOOR SPIN is opened, LINK BRAKE which con-
nect to DOOR SPIN loosens. And then the BRAKE BAND
touches the DRUM COUPLING assembly and stops the BAS-
KET SPIN as it is pulled by the SPRING in the BRAKE FIX
PLATE assembly.
BRAKE BAND GAP CONTROL METHOD
The BAND BRAKE works best when the gap between it and
the DRUM COUPLING is about 2mm when the DOOR SPIN
is closed. The BASKET SPIN stops slowly if the gap between
the two is too narrow, the BASKET SPIN revolution is affected
and the PLATE CONTROL WIRE may be adjusted to main-
tain the BRAKE BAND gap adequately.
WASH DECELERATOR ASSEMBLY
The initial deceleration following the activation of the WASH MOTOR takes place through the PULLEY MOTOR
and PULLEY PULSATOR, and the secondary deceleration is done by the gear in the GEAR HOUSING which also
increases their revolution strength. This revolution speed and strength is delivered to the PULSATOR, which is
then able to cause water current that is strong yet soft so that wash loads are not damaged.

GEAR HOUSING ASS’Y
The GRAR HOUSING ASSEMBLY is a transmission device which turns the PULSATOR at 6:1 lowered speed
through the gear unit assembly which receives power at the GEAR SHAFT UNIT.
1) The two sides of the GEAR SHAFT UNIT are supported by the
OILLESS BEARING in the GEAR HOUSING ASSEMBLY.
2) The GEAR UNIT ASSEMBLY is connected to the GEAR
SHAFT 1 and GEAR SHAFT UNIT by the GEAR and GEAR
UNIT respectively.
3) The two sides of GEAR SHAFT 1 are supported by the OIL
SEAL and OILLESS BEARING in the GEAR HOUSING
ASSEMBLY.
BELLOWS ASS’Y
The wrinkled rubber device on the botton of the BASKET SPIN is
called BELLOWS ASSEMBLY.
It has a waterseal and a oilless metal inside to prevent leakage and so that the BASKET SPIN may work smoothly.
Much lint may be obtained depending upon the kind of clothes to
be washed and same of the lint may also be suck to the clothes.
To minimize this possibility, a lint filter is provide on the upper part
of the FILTER OVERFLOW to filter the wash water.
Use of the lint filter during every wash is recommend.
CLEANING THE LINT FILTER
1) Remove the FILTER AS from the FILTER OVERFLOW by
pressing it downwards.
2) Turn the FILTER AS inside out, and wash the lint off with
water.
3) Return the FILTER AS it was, and fix the FILTER AS to the
FILTER OVERFLOW.
