PREFACE
Descriptions in this manual are based on the following conventions.
1. In the Basic Operation section, the roles of each function, relationships between electrical
and mechanical systems, and the timing for each part are summarized.
The mark indicates mechanical drive transmission. The mark
accompanying a signal name indicates the flow of electrical signals.
Flow charts are also used in the summary of operation.
The symbols used in the flow charts are as follows:
2. In the descriptions of digital circuits, "1" or "H" indicates a high voltage level, and "0" or
"L", a low voltage level. However, the actual voltage values vary depending on the circuit.
3. It is assumed that the Printed circuit board (PCB) will not be repaired by the user. There-
fore, the descriptions of the circuits on the PCB are limited to block diagrams.
4. Troubleshooting is described using procedural tables.
The procedural table is a variation of a general flow chart.
An example is shown below.
e.g. No power is supplied.

• If you want to know the possible causes of any specific problem (suspected parts), refer to
the "Cause" column in the table.
In the event "No power is supplied" as shown in the above table, an unplugged power
source, power source failure, blown fuse, and other causes can be considered.

PREFACE
• In order to remedy a problem, check the Steps in order. Answer the first "Check item"
question. If your answer matches that given in the "Result", follow the corresponding proce-
dure in the "Remedy" column. If your answer is not the same, go on to the next step and
repeat the same procedure.
• When checking voltages using a tester is required, it will be specified in the check item.
For instance; "measure the voltage between J102-1 (+) and JI02-2 (-) on the engine control-
ler PCB". In this case, apply the plus and minus leads of the tester to the (+) and (-) termi-
nals indicated after the connector numbers:
e.g. JI02-1 (+): Plus lead
JI02-2 (-): Minus lead
5. The signal address of the circuit diagram is shown by applicable pages of each controller
(indicated at the upper right of the circuit diagram) and its location.

When checking voltages with a tester, touching the components or connector terminals on
the PCB with the hands may cause an electric shock. It is advisable to wear rubber gloves
or the like when power is supplied to the machine to protect yourself from electric shock.
