11-6. Reassembly Requiring Adjustment
(1) Adjustment of squareness between the saw blade (dummy disc) and the fences

7.5 A max.
After disassembly or replacement of the Base Ass'y [169] ,
Turn Table [107] , Fence (A) [165] , Fence (B) [152] or Hinge
[30A] , it is necessary to perform necessary adjustment to
ensure that the fences are positioned at precise right angles
with relation to the saw blade (or dummy disc). Align fence (B)
with the saw blade (or dummy disc), and adjust them as
necessary to ensure squareness (tolerance: 0.2/100 mm).
As shown in Fig. 44, use a square to adjust fence (B) so that it
is square with the saw blade. Next, use a straight edge to
adjust fence (A) so that it is exactly aligned with fence (B).
Finally, use the square to confirm squareness of fence (A) with
the saw blade (tolerance: 0.2/100 mm).
(2) Reassembly of the Turn Table [107]
When reassembling the Turn Table [107] and the
Base Ass'y [169] , tighten the Nylon Nut M8 [118]
so that the Turn Table [107] turns smoothly without
excessive play or vibration. During reassembly,
liberally apply grease (Hitachi Motor Grease) at
the point marked "A" in Fig. 45.
