10-2. Reassembly
Perform reassembly in reverse order of disassembly while observing the following precautions.
(1) Prior to reassembly, measure the insulation resistance of the armature ass'y, stator ass'y, switch and other
electrical components with a DC 500 V Megohm Tester, and confirm that the insulation resistance of each part
is more than 5 M .
(2) Dielectric strength test
After testing the insulation resistance, apply 1,200 volts (for 100 --- 127 V products) or 1,800 volts (for 220 ---
240 V products) between the blade of the Power Cable [112] and the Body Shell [99] for one second with the
Rocker Switch [118], NVR-Switch [161] ON, to check that no dielectric breakdown will take place.
(3) No-load current value
The figures indicated below are the no-load current values after the machine is operated without load for 30
minutes.
No-load Current (max.): 8.5 A at AC single phase 110 V, 50 Hz
No-load Current (max.): 6.2 A at AC single phase 115 V, 60 Hz
No-load Current (max.): 3.9 A at AC single phase 230 V, 50 Hz
No-load Current (max.): 3.6 A at AC single phase 240 V, 50 Hz
(4) When assembling the Slide Plate [61], see Fig. 31 for the direction in which it is mounted on the Body [70].
Thoroughly wipe off the old grease on the sliding portion between the Slide Plate [61], and the Slide Bracket
[62] and Bracket [211].
Then apply two grams of motor grease No. 29 (Code No. 930035) there. Thoroughly wipe off the old grease in
the gear box of the Bracket [211], and apply two grams of motor grease No. 29 (Code No. 930035) to the
Needle Bearing [210]. Also thoroughly wipe off the old grease on teeth of the Helix Gear [208] in the Spindle
Ass'y [201], pinion of the Armature Ass'y [212], thread portion of the Screw Bar [68], and teeth of Bevel Gear
(A) [59] and Bevel Gear (B) [67]. Then apply motor grease No. 29 (Code No. 930035).
Refer to Fig. 30 for the part numbers of the 200 level.
