[7] Replacing Armature
DISASSEMBLING
1. Remove Carbon brushes.
2. After separating Stop ring E-8, Lever 40, M6 Hex
nut and Flat washer from M6x90 Flat head screw,
loosen three M5x40 pan head screws. (Fig.15)
5. Pull Armature out of Motor housing.
6. Remove Ball bearings of the Armature.
ASSEMBLING
Note: 1) When passing Armature through York unit, Armature is attracted to the magnet of Yoke unit.
Therefore, pay attention not to scratch Armature coils. Do not pinch your fingers between Fan of Armature and
Yoke unit.
2) When fixing Motor housing to Blade case complete, be sure to mount Motor housing transversely to Blade case
complete to prevent Baffle plate from being dropped out of Motor housing. (Fig. 15).
[8] Adjusting for accuracy of 90 and 45 cut
As illustrated in Fig.16, use Triangular rule and hex wrench 2.5 to set the desired angle.
Adjust the fastening torque of M5 thrust head screw in order to prevent backlash when doing cutting depth adjustment.
See Fig.17.
Adjust the locked position of Lever 40 within 30 degrees from horizontal line as illustrated in Fig.18.
