Remove the four Tapping Screws (W/Flange) D5 x 90

, provided between
Casing (B)
[46]
and the Gear Cover
[10]
(including the Inner Cover Ass'y

to open a gap between them. Then, apply two flat-blade screwdrivers at diagonally opposite points (near the
screw mounting holes) between the Inner Cover Ass'y
[40]
and Casing (B)
[46]
and pry them gently apart so
that the gap between them is enlarged evenly at both sides. When the gap is opened sufficiently, the dust
collection mechanism, consisting of Casing (B)
[46]
, Casing (A)
[69]

Then, after separating Casing (B)
[46]
from Casing (A)
[69]
, support Casing (A)

,
should it come off together with the Dust Shaft
[65]
, insert two flat-blade screwdrivers between the back
surface of the Dust Fan
[48]
and the Ball Bearing 6001DDCMPS2L
[67]
, and pry them gently and evenly apart
to remove the Ball Bearing 6001DDCMPS2L
