Chapter 1 General Information
1-1. General Guidelines
When servicing,observe the original lead dress.If a short circuit is found, replace all parts which are
overheated or damaged by the short circuit.After servicing ,see to it that all the protective devices such as
insulation barriers ,insulation papers shields are properly installed .Confirm that the screws,parts and wiring
which were removed in order to service are put in the original positions, or whether there are the portions
which are deteriorated around the service places serviced or not. And be sure safety of that.
