The Front Grille B Ass'y once removed cannot be re-

used. Be sure to use a new Front Grille B Ass'y for re-

placement.

* The Front Grille B Ass'y is fixed with 4 dowels. Use full

care when removing it so as not to cause damage to the

main unit.

a. Push up the Front Grille B Ass'y with a Flatblade screw-

driver or the like inserted from the rear. (Fig. 1)

b. Remove the Front Grille B Ass'y by lifting it up.

c. Remove 4 screws (1) and remove the Driver Woofer.

(Fig. 2)

d. Remove broken dowels remaining in 4 installation

holes.

e. Install the Driver Woofer using 4 screws (1).

(Fig. 2)

f. Apply quick drying bond or the like to dowels of the new

Front Grille B Ass'y and install them.

(When installing new Front Grille B Ass'y, its dowels will

come off easily if they are inserted into holes without

applying quick dry bond or the like.)
