CONDITION CHECKPOINT FIGURE CHECK METHOD REMEDY
The motor doesn’t
rotate.
CORD REEL PAR-
TITION UNIT
• Check the continuity at both
ends of the Plug and both ends
of the Lead Wire Terminal of the
Cord Reel Partition Unit. (Dis-
connection check)
• Check the continuity of the Lead
Wire connected to the Body
Partition Assy.
• There must be no problems
between the Cord Reel Assy
and the Body Partition Assy
(e.g. burns in the contact, entry
of dust).
• If there is no continuity, replace
the Cord Reel Assy, Body Parti-
tion Assy, or Cord Reel Partition
Unit.
MOTOR • Check the continuity between
the terminals of the Motor.
• Confirm that the Motor can be
rotated by fingers without being
locked.
• Visually check for burns in the
Motor (e.g. burns in the coil).
• If there is a problem, replace the
Motor Set.
* Also check and replace
the ON/OFF Switch (with
the Fuse Unit).
POWER CON-
TROL UNIT
• There must be no broken com-
ponents.
If they are normal:
(1) T1-T2: There is not continu-
ity.
(2) T1-G: There is continuity.
• There must be no broken foil of
the Printed Circuit Board.
• There must be no breaks in the
Lead Wires.
• If there is a problem, replace the
Power Control Unit.
FUSE UNIT • Check if the Fuse has blown.
Causes of fuse blowing:
1. Overcurrent
2. Burn of the Motor
3. Short-circuiting due to incor-
rect wiring
• Replace the ON/OFF Switch
(with the Fuse Unit/Thermo Pro-
tector).
*If a burn in the Motor
caused the Fuse to blow,
then also replace the
Motor.
THERMO PRO-
TECTER
• Continuity check.
ON/OFF SWITCH • Check the continuity by press-
ing the ON/OFF Switch.
1. The Motor
doesn’t rotate.
2. The Power Con-
trol doesn't func-
tion.
POWER CON-
TROL UNIT
• Check that the Triac has not
been short-circuited.
If there is continuity between T1
and T2, then there is a problem
in the components.
• Replace the Power Control Unit.
POWER CON-
TROL SWITCH
• The resistance between A and
B must be switchable.
* See the circuit diagram
(6. Printed Circuit Board)
for the switch resistances.
• Replace the Power Control
Switch.

The Cord cannot
be pulled out.
CORD REEL PAR-
TITION UNIT
• If the Cord cannot be pulled out,
press the Brake Lever and con-
firm that the Cord can be
rewound.
Repeat operations to rewind
and pull out the Cord two or
three times and confirm that it
can be normally rewound.
• If it is impossible to resolve the
problem due to an abnormal
condition of the Cord, separate
the Body, untwist the Cord, and
rewind it. Or, replace the Cord
Reel Unit and rewind the Cord.
1. The Cord cannot
be rewound.
2. The pulled out
Cord cannot be
locked.
Separate the Body and;
• Confirm that a sufficient number
of spare turns have been made.
• Confirm that the Cord Reel
Spring is working.
• Confirm that the Brake Lever
Unit is working correctly to stop
the Cord from rewinding.
• Make spare turns according to
the engraved number of turns,
or;
Replace the Cord Reel Unit.
Replace the Cord Reel Parti-
tion Unit.
1. The suction
power is low.
2. The Motor stops
during vacuuming.
(The Thermo Pro-
tector works.)

4 Disassembly and Assembly Instructions
Important: Always turn the vacuum cleaner’s power off before replacing components.
Remove the power cord and plug from the mains.
* Attention
(1) When disassembling the vacuum cleaner, check the connections and wiring (pulling) of each component, and ensure
that everything is restored correctly once repairs are complete.
(2) Handle all disassembled components and packing with care, and be sure to replace any components that may be acci-
dentally damaged.
(3) Once repair operations are complete, always inspect the area around the repairs for any degradation, and ensure that
all components that were removed for repair have been replaced in the correct wiring configurations. It is also necessary
to test the operation of the vacuum cleaner and ensure that it is safe for subsequent use.
• Insulation resistance:
Must be at least 5MΩwhen a direct current of 500V is applied between the power plug terminals and the exterior of the motor.
• Dielectric strength:
Must be able to withstand 1250V of alternating current applied between the power plug terminals and the exterior of the motor for
one minute.
(4) Do not make changes to models, components, or materials during repairs and services.
(5) If a wiring unit has been supplied as a spare part, the wiring unit must be simply replaced as it is, without any addi-
tional repairs or connections made to even part of the wiring.
(6) Insert/remove the fast-on terminals by pushing/pulling them straight out without jiggling them or applying unneces-
sary force.
