4 Disassembly and Assembly Instructions
Precautions: Make sure to power off the vacuum cleaner before replacing the parts.
Disconnect the plug from the outlet.
Caution:
(1) When disassembling, check the component fitting state and wirings. After repairing, always restore them to the origi-
nal state.
(2) Carefully handle the removed components, packing, etc. If they are damaged, then replace them with new ones.
(3) 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.
(4) Do not alter the model, parts, or materials during repair.
