MANUAL FORMAT
All of the procedures in this manual are organized in a sequential, step-by-step format. The informa-
tion has been complied to provide the mechanic with an easy to read, handy reference that contains
comprehensive explanations of all disassembly, repair, assembly, and inspection operations.
In this revised format, the condition of a faulty component will precede an arrow symbol and the
course of action required will follow the symbol, e.g.
Bearings
Pitting/damage →
Replace.
EC084002
HOW TO READ DESCRIPTIONS
To help identify parts and clarify procedure steps, there are exploded diagrams at the start of each
removal and disassembly section.
1. An easy-to-see exploded diagram 1
is provided for removal and disassembly jobs.
2. Numbers 2
are given in the order of the jobs in the exploded diagram. A number that is
enclosed by a circle indicates a disassembly step.
3. An explanation of jobs and notes is presented in an easy-to-read way by the use of symbol
marks 3
. The meanings of the symbol marks are given on the next page.
4. A job instruction chart 4
accompanies the exploded diagram, providing the order of jobs, names
of parts, notes in jobs, etc.
5. Extent of removal 5
is provided in the job instruction chart to save the trouble of an unneces-
sary removal job.
6. For jobs requiring more information, the step-by-step format supplements 6
are given in addi-
tion to the exploded diagram and job instruction chart.

ÍFasten the start switch lead, main switch lead,
engine stop switch lead, and thermo switch lead
to the frame with a plastic locking tie at the loca-
tion shown in the illustration. Face the buckle of
the plastic locking tie upward, and then cut off
the excess end of the tie.
Î When installing the crankcase breather hose,
make sure that it does not contact the muffler
and is not twisted. Ï
Fasten the wire harness to the frame with a plas-
tic locking tie at the location shown in the illustra-
tion, making sure that the plastic locking tie does
not contact the crankcase breather hose. Cut off
the excess end of the plastic locking tie, and
then face the cut end of the tie upward. The cut
end of the plastic locking tie should be 5 mm
(0.20 in) or less.
Ð Insert the wire harness holder completely into
the hole in the frame.
