(3) When connecting the Earth Terminal
[37]
to
the internal wire (middle wire among three) of
the Noise Suppressor
[38]
, strip off about 6
mm of the insulation sheath on the internal
wire, and then press-connect it together with
the Earth Terminal
[37]
with a clamping tool
available on the market.
(4) Confirm that the spring end does not hold the
pigtail when mounting the carbon brush. Do
not catch the pigtail in the tail cover when
mounting the tail cover.

Upon the completion of disassembly and repair, measure the insulation resistance and conduct a dielectric
strength test.
Insulation resistance: 10 M
Ω
or more with DC 500 V megohm tester
Dielectric strength test: AC 4,400 V for 3 seconds, with no abnormalities ----------- 220 to 240 V products
AC 3,000 V for 3 seconds, with no abnormalities ----------- 110 to 127 V products
After no-load operation for 30 minutes, the no-load current value should be as follows:
