(This illustration shows the mechanism ass'y set up verti-
cally. In order to
set
it
up vertically, remove the governor
P.C.B. from the chassis.)
2.
Check procedure
1) Disassemble as shown in Fig. 1. (The unit does not
operate in this condition.)
2) Solder the wires at points
@
to
@
where the wires
go out. (Avoid re-soldering after this as it will cause a
malfunction after assembly.)
3)
Connect Q306 collector and GND by soldering in a
wire. (Since removing the governor P.C.B. causes auto
stop to operate, this
is
defeated by the wire.)
