* Keep away from fire or spark.
* During disassembling, use care to minimize spillage of gasoline.
* Spilled gasoline should be wiped off immediately.
* Work in a well-ventilated area.
* To prevent the fuel system (fuel tank, fuel hose, etc.) from contamination
with foreign particles, blind all openings.
* After removing the throttle body, tape the cylinder intake section to pre-
vent foreign particles from entering.
