3. Removal of front panel ass'y
* The front panel ass'y is fixed to the cabinet ass'y with
dowels. As a flatblade screwdriver is used for removal,
use special care not to cause damage to the cabinet
ass'y.
a. Remove 2 bushings. (Fig. 4)
* Used bushing, once removed, cannot be reused. Be
sure to use a new bushing in place of the removed
used bushing.
b. First, insert a flatblade screwdriver at 2 dowel positions
and push up the front panel ass'y. (Fig. 4)
c. Next, using the metalblade or the like, push the front
panel ass'y upward until it comes off. (Fig. 4)
Note: • Removing the front panel ass'y with the
flatblade screwdriver only without using the
metalblade or the like may cause a damage to
the front panel ass'y.
• When installing the front panel ass'y, apply
quick-drying bond or the like to dowels and
then fit them into dowel holes for secure instal-
lation. (The front panel ass'y will come off eas-
ily if its dowels are fitted into dowel holes with-
out applying quick-drying bond or the like.)
