CAUTION
NOTE
Gasoline is highly flammable, therefore smoke and fire are strictly forbidden in the work
place. Special attention should also be paid to sparks. Gasoline may also be explosive when it
is vaporized, so operation should be done in a well-ventilated place.
Do not over twist or bend the cables. The twisted cables may cause poor operation.
Loose the high pressure fuel line before disassembly, discharge the fuel in the high pressure fuel
line and put it in a container.
When the body of throttle valve is disassembled, the air intake shall be covered by dishcloth or tape,
for avoiding the entry of other objects into the engine from the air intake side of the engine.
When the vehicle will be stored for more than one month, the gasoline in the high pressure fuel line
and cap of the fuel injector must be discharged. Otherwise, the gasoline will age and form colloidal
elements which may block the nozzle of fuel injector, therefore the engine cannot start or the rotate
speed is unstable.
