(1) Keep the engine level, and detach the oil gauge.

(2)Fill oil up to the edge of the oil refill port. (Refer to Fig.2 of the preceding page).

Feed oil with the lubricant refill container.

(3)Securely tighten the oil gauge. Insufficient tightening may cause oil leakage.

Point 2 in Replacement of Oil: “If oil spills out”

–If oil spills out between the fuel tank and engine main unit, the oil is sucked into through the cooling air intake port, which will contaminate the engine. Be sure to wipe out spilt oil before start of operation.

REFUELING

Handling of Fuel

It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refueling must be performed in a sufficiently ventilated room or in the open air. Never inhale fuel vapor, and keep fuel away from you. If you touch fuel repeatedly or for a long time, the skin becomes dry, which may cause skin disease or allergy. If fuel enters into the eye, clean the eye with fresh water. If your eye remains still irritated, consult your doctor.

Storage Period of Fuel

Fuel should be used up within a period of 4 weeks, even if it is kept in a special container in a well-ventilated shade. If a special container is not used or if the container is not covered, fuel may deteriorate in one day.

STORAGEOF MACHINEAND REFILLTANK

–Keep the machine and tank at a cool place free from direct sunshine.

–Never keep the fuel in the cabin or trunk.

Fuel

The engine is a four-stroke engine. Be sure to use an automobile gasoline (regular gasoline or premium gasoline).

Points for Fuel

–Never use a gasoline mixture which contains engine oil. Otherwise, it will cause excessive carbon accumulation or mechanical troubles.

–Use of deteriorated oil will cause irregular startup.

Refueling

WARNING: INFLAMMABLES STRICTLY PROHIBITED

Gasoline used: Automobile gasoline (unleaded gasoline)

–Loosen the tank cap a little so that there will be no difference in atmospheric pressure.

–Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that the refuel port will be oriented upward. (Never refill fuel full to the oil refill port.)

–Wipe well the periphery of the tank cap to prevent foreign matter from entering into the fuel tank.

–After refueling, securely tighten the tank cap.

￿If there is any flaw or damage on the tank cap, replace it.

￿The tank cap is consumable, and therefore should be renewed every two to three years.
