NOTE
Method Used to Replace Fuse on
PCB Ass'y
1. Remove the PCB Ass'y from the
electrical component box.
2. Remove the fuse from PCB Ass'y
using pliers while heating the sol-
dered leads on the back side of the
PCB Ass'y with a soldering iron (30W
or 60W). (Fig. 20)
3. For replacement, insert a fuse of the
same rating to the intended position
and solder it.
(Allow time to radiate heat during sol-
dering so that the fuse does not melt.)
