(9) Clean air cleaner
Occasionally, disassemble the intake silencer
(air cleaner) and inspect it. Because the
element filters the air, if it is used over a long
period of time it will become clogged and this
decreases the amount of intake air, and may
also be a cause of decreased output and poor
emission.
1) Disassemble the air cleaner and clean it with
a neutral detergent.
2) Reassemble after it is completely dry.
(10)Adjust the tension of the alternator
driving belt.
Refer to 2.2.2(4) for the procedure.

bolts such as;
a) Flexible engine mount bolts
