SAFETY PRECAUTIONS
BEFORE OPERATING THIS VACUUM CLEANER, READ THIS SERVICE MANUAL THOROUGHLY,
AND OBSERVE EACH POINT CAREFULLY.
1. Motor filter(Air Cleaner)
1) This filter is reusable.
2) Never use the vacuum cleaner without filter.
It may damage the motor.
3) If the suction power is decreased after cleaning
dust tank, clean or wash the motor filter and air
filter.
4) The motor filter and air filters clean or wash at
least once a month
NOTE : Reusing of the motor filter.
• Never wash the filter in a washing machine or in a
dishwasher.
• Never use hot water for washing the filter.
• Reuse the filter after drying it completely in the
shade for a day.
• Do not dry near fire or direct sunray.
2. Exhaust filter (Micro filter)
1) This filter is reusable filter.
2) For cleaner air, filter must be assembled.
NOTE : Reusing of the exhaust filter.
• Never wash the filter in a washing machine or in a
dishwasher.
• Never use hot water for washing the filter.
• Re-use the filter after drying it completely in the
shade.
• Do not dry near fire or direct sun ray.
Option (Choose according to buyer’s request)
Exhaust filter (HEPA filter)
1) This filter is reusable HEPA filter.
2) For clean air, filter must be assembled.
3) Dust off filter. (Do not wash filter with water.)
4) Clean the exhaust filter once 1 year.
NOTE : Reusing of the exhaust filter.
Do not wash filter with water.
Do not brush the filter. This will cause permanently
damage allowing dust to by-pass the filter.
3. Avoid suction such materials as :
1) Liquid or wet dust :
Clogs the ventilation holes, reduces the suction
power significantly and harms the motor.
2) Inflammable liquids such as benzene, alcohol or
solvents.
3) Burning objects such as cigarette butts.
4) Bulky objects such as vinyl, paper etc.
5) Sharp objects such as needles, pins, metal, glass
particles etc.
4. Attachments
Nozzle : for cleaning wooden floor, the room floor
and carpet.
Crevice Tool : for cleaning any crevice, inside
corners or window frames. However, do not use
the crevice tool more than 20 minutes because it
may cause harm to the motor.
Dusting brush : for cleaning clothes curtains.
Upholstery nozzle : Clean the furniture, mattresses etc.
5. Close supervision is necessary when this
vacuum cleaner is used by or near children.
Childrenís carelessness may cause damage to
the cleaner or injure persons.
6. Air exhausted from the vacuum cleaner is
normally warm. But if extraordinarily hot air is
exhausted, check if the telescopic tube, hose or
clean filter is clogged or not.
7. Electric shock could occur if used outdoors or
on wet surfaces.
CAUTIONS
BEFORE ATTEMPTING TO SERVICE OR ADJUST ANY PART OF THE VACUUM CLEANER,
DISCONNECT THE ELECTRICAL POWER SUPPLY CORD FROM THE WALL OUTLET.
1. Motor exchange
1) Separate the Body Cover and Body Base by
unfastening the screws.
2) After disconnecting the lead wires, replace the old
motor with a new one
.
2. In case of exchanging other parts.
refer to the exploded view.

Methods for Disassembly, Assembly and Repair of Main Parts
Need-to-know for disassembly
Pull out the plug before disassembly and adjustment.
1. All the parts are almost connected by screws or
assembled by insertion. Disassemble in order with
reference to the disassembly diagram.
2. Do not proceed with further disassembly except the
necessary part. Parts beyond the disassembly
diagram are not to be disassembled.
Method for disassembly of main parts
1. Method for disassembling the cover of the main
unit.
1)
Press the release button on the handle of the dust
tank.
Then pull the tank assembly out of the main unit.
2) Remove pre-filter assembly from the main unit.
4) Loosen the screws in the base of the main unit.
(with TPL4X20: 7 pieces,
type driver)
5) Lift the cover assembly of the main unit
3) Remove the exhaust filter on the back side.
6) Unplug the cable on the board.

2. Method for disassembling case assembly / cord
reel
1) Loosen the screw fixing the chamber.(with
TPL4X16:1 piece, type drive)
2) Unplug the cable on the board.
(Hold the board tightly not to move)
4) Lift the Case Assembly
5) Lift the Cord Reel Assembly
3) Unplug the cable between board and motor
3. Method for disassembling Top cover assembly
1) Loosen the screw fixing the Top cover assembly.
(with TPL4X14:4 piece, type drive)
2)Remove Top cover assembly from the main unit.

3. Replacement of motor
1) Disassemble the motor assembly as shown in the
figure.
2)
For re-assembly after disassembling the motor
cover, do so in the reverse sequence and insert
the packing seal, motor and mount packing. During
the assembly, make sure to prevent the packing
seal and motor mount packing from dropping out
(which may reduce the suction force).
4.Replacement of PWB Assembly
1) After removing the cable on board (Page 6)
2) Loosen the 1 screw fixing the board.(with
FAB3X8: 2 pieces, type drive)
3) Re-assemble PWB Assembly.
Do insert rubber Gasket before assembling PWB
