2) Visually check that air cleaner filter is not excessively dirty, dam-
aged or oily.
3) Clean filter with compressed air from air outlet side of filter.
4) Install air cleaner filter into case.
5) Clamp case cap securely and install hose to case and bracket
if removed.
Air Cleaner Filter Replacement
Replace air cleaner filter with new one according to steps 1), 4) and
5) of Air Cleaner Filter Inspection.
ITEM 3-2
Fuel Lines Inspection

Check fuel lines for loose connection, deterioration or damage
which could cause leakage.
Make sure all clamps are secure.
