Checking Of Insulation Distance; No-Load Current; Reassembly Requiring Adjustment - Hitachi C 12LSH Technical Data And Service Manual

11-5. Checking of Insulation Distance

Do not remove too much of the insulation coating at the internal wire connection. Take care not to let the core of
the internal wire stick out the Connector 50092 [267] or let the internal wires get caught in a joint between Switch
Handle (R) [269] and Switch Handle (L) [263].

11-6. No-load Current

After no-load operation for 30 minutes, the no-load current values should be as follows.
Voltage
No-load current

11-7. Reassembly Requiring Adjustment

(1) Adjustment of squareness between the saw blade (dummy disc) and the fences
It is necessary to check and adjust the right-angle orientation
between the saw blade (dummy disc) and the fence after
disassembly and replacement of the Base Ass'y [59], Turn
Table [26], Fence (A) [96], Fence (B) [51], Holder (A) [145]
and Hinge (A) [173] and after disassembly, reassembly and
adjustment of the Ball Bushing [144]. Adjust the squareness
(rated value 0.15/100 mm) by moving the fences along the
saw blade (dummy disc).
First adjust the squareness between the saw blade and either fence. Then adjust flatness of the two fences by
applying a straight edge to the right and left fence surfaces. Finally, apply a square to the fence surface that
has not been checked yet and make sure it forms squareness (rated value 0.15/100 mm) with the saw blade.
(2) Adjustment of the lower limit position of the saw blade
Adjust the unit so that the saw blade (305 mm (12")) is 9 to 11 mm (23/64" to 7/16") below the base surface (or
top surface of the table insert). Lower the Gear Case [275] (head) and make Hinge (A) [173] contact with the
Nylock Bolt M8 x 40 [274] for lower limit position adjustment. Turn the Nylock Bolt M8 x 40 [274] with a 13-
mm wrench and change the height to adjust the lower limit position of the saw blade.
