Check the following after reassembly:
(1) Confirm normal switching operation of Switch (E) (1p Screw Type) W/Lock
[41]
.
(2) Confirm that the stroke speed changes depending on the turning amount of Controller
[43]
.
(3) Confirm that the blade can be attached securely.
Upon completing disassembly and repair, measure the insulation resistance and conduct an insulation test
(dielectric strength test).
Insulation resistance: 7 M
Ω
or more with 500 V DC megohm tester.
Dielectric strength:
AC 4,000 V for 1 minute, with no abnormalities ---- 110 V, 220 V, 230 V, 240 V
AC 2,500 V for 1 minute, with no abnormalities ---- 120 V
After no-load operation for 30 minutes, the no-load current value should be as specified below at a
frequency of 50/60 Hz.
