FUNCTION
The main switch remains ON during the washing time set by turning the timer knob.
At the same time, the internal switch T1 and T2 which provide power to WASH MOTOR alternately at assigned Intervals.
Select switch knob sets the wash type by means of controlling the interval of internal switch contact.

SPIN TIMER
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 upon 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 1,600rpm 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 atop the DOOR SPIN falls off the
contact, and cuts off the power going into the SPIN MOTOR.

BRAKE SYSTEM
BRAKE SYSTEM
When the DOOR SPIN is opened, LINK WIRE which connect
to DOOR SPIN loosens. And then the BRAKE BAND touches
the DRUM COUPLING assemply and stops the SPIN DRYER
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 SPIN DRYER stops slowly if the gap between
the two is too narrow, the SPIN DRYER 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
increeases 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
GEAR HOUSING ASS’Y
The GRAR HOUSING ASSEMBLY is a transmission device which turns the PULSATOR at 3.3:1 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.
SPIN GELLOWS ASS’Y
The wrinkled rubber device on the botton of the BASKET SPIN is
called SPIN 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 provied 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.
