Checking Of Insulation Distance; No-Load Current; Reassembly Requiring Adjustment - Hitachi C 10FSB 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 [158] or let the internal wires get caught in a joint between Handle (L)
[148] and Handle (R) [153].

11-6. No-load Current

After no-load operation for 31 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
Fence (B)
Square
Fig. 73
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

The Bolt M8 x 50 [83] must be easily turned by hand when performing the operations specified in page 14 of the
Instruction Manual "4. Lower limit position of saw blade when cutting a large workpiece" and page 25 "11. Groove
cutting procedures". Check that the Bolt M8 x 50 [83] can be turned idly by hand.

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 [54A], Turn
Table Ass'y [26], Fence (A) [53], Fence (B) [23], Holder (A)
[115] and Hinge (A) Ass'y [75] and after disassembly,
reassembly and adjustment of the Ball Bushing [106].
Adjust the squareness (rated value 0.15/100 mm) by moving
the fences along the saw blade (dummy disc).
Adjust the unit so that the saw blade (255 mm (10"))
is 9 to 11 mm below the base surface (or top surface
of the table insert). Loosen the Wing Nut M8 [82].
Turn the Hex. Socket Set Screw M8 x 10 [78]
counterclockwise viewing from the rear of the
Turn
machine using a 6-mm hex. bar wrench at the
opposite side of the Bolt M8 x 50 [83].
Turn the Bolt M8 x 50 [83] until the head of the bolt
contacts the Gear Case [196] then change the height
to adjust the lower limit position of the saw blade.
Press the Hex. Socket Set Screw M8 x 10 [78]
against the tip of the Bolt M8 x 50 [83] and turn the
Wing Nut M8 [82] until it contacts the Gear Case
[196] to tighten it securely.
