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 MΩ 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.

Voltage (V) 110 120 220 230 240

Current (A) Max. 4.0 3.0 1.8 1.8 1.8
