10-2. Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, special attention
should be given to the following items.
(1) Prior to reassembly, measure the insulation resistance of the Armature Ass'y [9], Stator [11], Switch [61], and
other electrical components and confirm that the insulation resistance of each part is 5 MΩ or more.
(2) When replacing Spring (A) [119], apply 5 grams of grease (Hitachi Motor Grease is recommended) to its inner
circumference.
(3) When inserting the Armature Ass'y [9] into the Housing Ass'y [1], install the Wave Washer [8] without fail.
10-3. Adjustments
(1) Perpendicularity adjustment of the TCT Saw Blade [87] (or dummy disc) and Vise (B) [108]:
After disassembly or replacement of the Base [135] and/or Vise (B) [108], adjust the perpendicularity of Vise
(B) [108] and TCT Saw Blade [87] (or adjustment disc).
(2) Height adjustment of the Hex. Hd Screw M10 x 65 [110]:
After disassembly or replacement of the Base [135], adjust the height of the Hex. Hd Screw M10 x 65 [110]
so that it is 88 mm above the upper surface of the Base [135].
On completion of adjustment, fasten the Hex. Hd Screw M10 x 65 [110] with the Nut M10 [111].
If the bolt height is too low, there is a danger that the TCT Saw Blade [87] may cut into the Base [135] or the
floor surface; if it is too high, the workpiece material may not be cut completely. Confirm correct adjustment.
(3) Height adjustment of the Bolt M10 x 60 [114]
After removing and replacing the Base [135], adjust the height of the Bolt M10 x 60 [114] so that the opening
between the Safety Cover [84] and the Saw Cover [37] becomes 10 --- 20 mm. Then secure each nut.
Properly adjust the height of the Bolt M10 x 60 [114]. If the height is too low, the Gear Case [29] may fall
backward and if it is too high, large-diameter workpieces cannot be cut.
10-4. Wiring
Ensure that the wiring is connected as shown below. As incorrect wiring may result in non-rotation or reverse
rotation, careful attention is required to ensure correct wiring.
