precautions, and also those listed in the Owner'sManual.
2. Parts which have a ; mark in the circuit diagram or in the parts
list are essential for safety. When replacing these parts, be sure
to use onlythe specified parts.

wind the lead wire and secure it by soldering.
5. Do not let the wiring come into contact with heat-emitting
devices (fuse resistor, radiator plate, etc.).

the unfinished or rough edge of a part.

from various directions to confirm that it does not slip out of
place.

interval between the soldered terminals or between the terminal
and surrounding metallic parts is at least the minimum required
(between the primary circuit and the chassis: atleast 6.5 mm;
between primary circuit terminals: at least 4.0 mm; between
primary circuit terminals and secondary circuit terminals: at least
6.5 mm.).
