● Gasoline is extremely flammable. Avoid fire in the work place, also paying particular attention to sparks. Furthermore,
the evaporated (gasified) gasoline is highly explosive. Work in a well-ventilated areas.
● Exhaust gas contains poisonous substance. Do not keep engine running for a long period of time in a closed, or poorly
ventilated area.
● Do not excessively bend or twist cable. Distorted or damaged cable may lead to mechanical malfunctions.
● Pay particular attention to the position of O-ring. Replace with new ones when disassembled.
● Loosen the drain bolt of the float chamber before disassembly, drain residual gasoline, and then, put in a vessel.
● If it is desired to store a vehicle for a period longer than 1 month, drain gasoline out of the carburetor float chamber.
Gasoline left in the float chamber will be deteriorated causing the slow jet to be clogged with deposits, and idling may
become unstable.
