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
(1) Adjustment of squareness between the saw blade (dummy disc) and the fences
Voltage, frequency
No-load current

After disassembly or replacement of the Base Ass'y [167],
Turn Table Ass'y [108], Fence (A) [172], Fence (B) [150] or
Hinge Ass'y [43], 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: 100 mm).
As shown in Fig. 55, 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 Ass'y [108]
When reassembling the Turn Table Ass'y [108]
and the Base Ass'y [167], tighten the Nylon Nut
M8 [104] so that the Turn Table Ass'y [108] turns
smoothly without excessive play or vibration.
During reassembly, liberally apply grease (Hitachi
Motor Grease) at the point marked "A" in Fig. 56.
