11-2. Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, special
attention should be given to following items.
(1) Prior to reassembly, measure the insulation resistance of the armature, stator, switch and other electrical
components and confirm that the insulation resistance of each part is more than 7 M .
(2) When assembling the Angle Regulator [32] and the Arm [120], apply 2 grams of Hitachi Motor Grease to the
oil groove of the Angle Regulator [32].
(3) When replacing the Torsion Spring [36], apply approximately 2 grams of Hitachi Motor Grease to the inner
circumference of the new Torsion Spring [36] prior to reassembly.
(4) When replacing the Rotation Slide Plate [72], assemble it into the unit as illustrated in Fig. 19. During
reassembly, apply 6 grams of Hitachi Motor Grease to the Rotation Slide Plate [72] against the sliding surface
of the Base [74].

Ensure that the Rotation Slide Plate [72] fits into
the groove portion of the Base [74].
(5) If the Center Shaft [75] at the bottom of the Base [74] is tightened excessively, the movement of the Table [60]
will become sluggish and heavy. If the bolt is loose, it will cause vibration and looseness of the Table [60]
which will reduce cutting accuracy. Adjust the Chuck Nut M8 [58] so that the Table [60] moves smoothly with
minimum play and vibration.
