    9-1. Disassembly (1) First, remove the bit. If further disassembly is attempted with the bit mounted on the router, it may cause damage to the cutting edges of the bit and/or serious injury to the handler. (2) Removal of the Base [76] ([75]) (Fig. 3) (a) Stand the router upright so that the bottom surface of the Base [76] ([75]) is directed downward.
  • Page 10 (g) Being very careful not to damage the magnet component, fit a 14-mm wrench onto the hexagonal portion of the Magnet [4], and loosen and remove it from the Armature [34] ([33]) (Model M 8V2 only). (h) Loosen and remove the three Machine Screws (W/Washers) M4 x 12 (Black) [43] ([42]), remove the Bearing Cover [57] ([56]), Pushing Button [59] ([58]) and Lock Spring (A) [58] ([57]).

For this reason, be sure to handle the armature and its associated parts very carefully during disassembly and reassembly.
