11-5. No-load Current
After no-load operation for 30 minutes, the no-load current values should be as follows.
11-6. Reassembly Requiring Adjustment

, 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:
0.4/100 mm). As shown in Fig. 38, 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:
0.4/100 mm).
(2) Reassembly of the Turn Table
[50]
When reassembling the Turn Table
[50]
and the
Base Ass'y
[78]
, tighten the Nylon Nut M8
[46]
so
that the Turn Table
[50]
turns smoothly without
excessive play or vibration. During reassembly,
liberally apply grease (Hitachi Motor Grease) at
the point marked "A" in Fig. 39.
