3 Troubleshooting Guide
CONDITION CHECKPOINT METHOD OF INSPECTION CAUSE / REMEDY
Motor does not rotate. Power supply cord Check power supply cord continu-
ity. Check cord reel U electrical con-
tinuity.
If there is no continuity, replace
cord reel U.
Fuse (250V, 10A)
(above PCB)
Check for fuse meltdown.
Visual meltdown inspection:
• Investigate the cause of the
meltdown
1. Burnt-out motor, coil short
circuit
2. Lead wire short circuit (short)
3. Burnt printed circuit board
(PCB)
If there has been a meltdown,
remove the problem fuse and
replace the PCB AU.
Motor unit Check electrical continuity between
motor unit terminals.
If there is no electrical continuity,
replace the motor unit.
ON/OFF switch Turn the switch on and off to check
electrical continuity
If there is any abnormality, replace
the PCB AU.
Printed circuit board (PCB) AU Check that there are no internal
part abnormalities (burnt, melted,
split, etc.).
If there is any abnormality, replace
the PCB AU.
Triac
(inside the printed circuit board AU)
Perform the following examination
and check the triac.
If there is any abnormality, replace
the PCB AU.
Motor runs, but there is no suction. Paper dust bag, dust box, second-
ary filter
Check if the paper dust bag or the
dust box is full of waste.
Is there some blockage in the sec-
ondary filter?
If the paper dust bag is full, replace
it with a new one.
If the dust box or the secondary fil-
ter is full of waste or there is a
waste blockage, throw out the
waste and clean.
Hose, extension wand, floor nozzle Check if there are any blockages. If there is a blockage, remove it.
Excessive vibration, excessive
noise
Motor unit Check if dust has accumulated in
the motor unit.
(Dust and waste can enter the
motor unit if there is no secondary
filter.)
Check for dust and waste in the
motor unit, as well as the condition
of the filter, and replace if neces-
sary.
Motor power (suction power) does
not change.
Printed control board (PCB) AU Turn the power control knob and
check if the suction power can be
changed.
If there is any abnormality, replace
the PCB AU.

4 Disassembly and Assembly Instructions
Caution:
When disassembling, check the component fitting state and wirings. After repairing, always restore them to the original
state.
Carefully handle the removed components, packing, etc. If they are damaged, then replace them with new ones.
After repairing, check that the components, etc., in the vicinity of the repaired sections are not damaged, the removed
components are in place, and the wirings are restored to the original state. Carry out the test run. Also check that the fol-
lowing requirements are met.
Insulation resistance
Must be 5 MΩor more when a DC voltage of 500 V is applied across the power plug and the motor core for one second.
Dielectric strength
Must withstand an AC voltage of 1,250 V applied across the power plug and the motor core for one minute.
Do not alter the model, parts, or materials during repair.
If a wiring unit is supplied as a repair part, replace the whole unit with the new one instead of repairing or reconnecting the
broken portions only.
Insert/remove the fast-on terminals by pushing/pulling them straight out without jiggling them or applying unnecessary
force.
4.1. Dust box lid U removal
1. Open the dust box lid U, insert a screwdriver between the
upper body and the area where the dust box lid U is
attached and move it in the direction of the arrow to
remove the dust box lid U from the upper body.
4.2. Separate the upper and lower
body units
1. Remove the four screws from the top of the body.
2. Remove the two screws on the rear side of the lower
body.

3. Remove the wheel supporter right and wheel supporter
left.
4. Remove the upper body.
4.3. Separate the cord reel U and
the body partition U
1. Remove the cord reel partition from the lower body.
2. Remove the two lead wire terminals.
*Pull the terminals out while holding down the termi-
nal lock release.
3. Slowly remove the plug from the body cover partition
stopper and release the pre-winding spring.
4. After inserting a screwdriver into the slit in the shaft and
turning 90 degrees to the left, pull the cord reel U away
from the body partition U.
*When assembling, carry out pre-winding for the
spring.
(The number of times to pre-wind is noted on the
metal plate.)

4.4. Printed Circuit Board (PCB) AU
removal
1. Remove the control terminal U, the power control and the
switch from the motor support cover U.
2. Remove the four screws affixing the motor support cover
U.
3. Remove the motor support cover U and remove the PCB
AU.
4. Disengage the fast-on terminals of the two lead wires
connecting the PCB AU.
*Note:
When disengaging the fast-on terminals, pull straight
out without lateral movement while holding down the
lock release.

4.5. Motor removal
1. Remove the motor support rubber (rear) from the motor
support front.
2. Remove the two screws from the motor support front.
3. Remove the motor support front from the motor unit.
4. Remove the motor support rubber (front) from the motor
unit.
5. Remove the noise suppressor U from the motor unit.
6. Remove the two lead wires from the motor unit.
Note:
Make sure that the thermal protector is on the under-
side when setting the assembled motor into the lower
body.
