Reassembly - Hitachi C 10FM Technical Data And Service Manual

10-2. 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, field, switch and other electrical
components and confirm that the insulation resistance of each part is more than 7 M Ω.
(2) When assembling the Support [39] and the Upper Arm [86], apply 2 grams (2 pcs.) of Hitachi Motor Grease to
the oil groove of the Upper Arm [86].
(3) When replacing the Torsion Spring [48], apply approximately 5 grams of Hitachi Motor Grease to the inner
circumference of the new Torsion Spring [48] prior to reaasembly.
(4) When replacing the Slide Plate [75], assemble it into the unit as illustrated in Fig. 12. During reassembly,
apply 6 grams of Hitachi Motor Grease to the Slide Plate [75] against the sliding surface of the Base [59].
(5) If the Center Shaft [74] at the bottom of the Base [59] is tightened excessively, the movement of the Table [64]
will become sluggish and heavy. If the bolt is loose, it will cause vibration and looseness of the Table [64]
which will reduce cutting accuracy. Adjust the Nut Chuck M8 [60] so that the Table [64] moves smoothly with
minimum play and vibration.
