Assemble by reversing the disassembly procedure.
Note 1. The recommended tightening torque for four 2x10 + Pan head
tapping screws is 0.15-0.35 N·m (Fig. 2-2-8) .
Note 2. Remember that the orientation of Flange matters (Fig. 2-2-5) .
Note 3. When tightening M6 Hex nut to fasten Fan 94 to Motor section:
• Hold Fan 94 as shown on right, with leather safety gloves on,
to prevent corotation of Fan 94 and M6 Hex nut.
• Turn M6 Hex nut clockwise with an impact driver and
Socket bit 10; if you use a DTD137 class impact driver,
set it in soft mode, then turn the nut for 0.5 minutes.
The recommended torque is 2-3 N·m.

Note 4. When handling or storing multiple Rotors,
be sure to keep a proper distance between Rotors.
Because Rotor is a strong magnet, failure to follow
this instruction could result in:
• Finger injury from being pinched between Rotors
•Magnetic loss of Rotors or damage to Rotors.
Note 5. When inserting Rotor into Stator:
・While pushing Stator against a workbench, insert Rotor straight into Stator.
・Do not pinch your finger between Rotor and Stator.
・Once Rotor has been inserted, do not force
it into Stator any further or you will break
the printed wiring board of Controller B.

Note. Even if this vacuum cleaner is used with care and according to the instructions in the user’s manual,
dust may accumulate in Rear block filters, reducing the capacity of this vacuum cleaner.
So whenever Upper and Lower housing completes are separated, remove two Rear block filters
(one on each side) from Upper and Lower housing completes, and then:
• Remove dust from the inside of Upper and Lower housing completes by blowing with compressed air.
•Remove dust from Rear block filters by blowing with compressed air or washing with water.

Note in Repairing
Whenever you find any trouble in your machine, first, refer to this list to check the machine for solution.
(1) Use a full charged battery that has the star mark. (Fig. T-1)
(2) When Housing is disassembled, check the conditions of the electrical parts
(Connectors, Lead wires, Switches, etc.), Rotor, Stator, Gear section, etc.
(3) Do the running test 10 times.
3TROUBLESHOOTING
Fig. T-2
Troubleshooting of Controller Using Tester
Trouble on Controller can be checked with Tester (1R402-A) as described in Fig. T-2.
Fig. T-1
Star mark
(1) Set Tester (1R402-A) to Diode mode ( ). (2) Remove Battery from the machine,
(3) Touch (+) Terminal with the black probe and (-) Terminal
with the red probe. Then wait until the reading voltage
reaches a stable value.
Note: You cannot make a correct test, if you touch
(+) Terminal with the red probe and (-) Terminal
with the black probe.

(4) If it reads 0.9 V-1.3 V, Controller is in order.
If it reads 0 V, about 0.4 V or about 0.8V,
FET (Field Effect Transistor) built in Controller
is broken, and Controller must be replaced.

Check the connection.
