BEFORE START OF OPERATION
Inspection and Rell of Engine Oil
– Perform the following procedure, with the engine cooled down.
– While keeping the engine level, remove the oil gauge, and conrm that the oil is lled within the upper and
lower limit marks.
When the oil is in short in such a way that the oil gauge touches the oil only by its tip, in particular with the
oil gauge remaining inserted in the crankcase without screwing-in (Fig. 1), rell new oil near the port (Fig. 2).
– For reference, the oil rell time is about 15 h (rell frequency: 15 times).
– If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of
replacement, refer to P. 21)
Recommended oil: SAE 10W-30 oil of API Classication, Class SF or higher (4-stroke engine for
automobile)
Oil volume: Approx. 0.1 L
Note: If the engine is not kept upright, oil may go into around the engine, and may be relled excessively.
If the oil is lled above the limit, the oil may be contaminated or may catch re with white.
Point 1 in Replacement of Oil : “Oil Gauge”
– Remove dust or dirt near the oil rell port, and detach the oil gauge.
– Keep the detached oil gauge free of sand or dust. Otherwise, any sand or dust adhering to the oil
gauge may cause irregular oil circulation or wear on the engine parts, which will result in troubles.
– As an example to keep the oil gauge clean, it is recommended to insert the oil gauge on its knob side
into the engine cover, as shown in Fig.3.
(1) Keep the engine level, and detach the oil gauge.
(2) Fill oil up to the edge of the oil rell port. (Refer to
Fig.2).
Feed oil with the lubricant rell container.
(3) Securely tighten the oil gauge. Insufcient 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 sufciently 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.
STORAGE OF MACHINE AND REFILL TANK
– 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 rell fuel full to the oil rell 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 aw or damage on the tank cap, replace it.
● The tank cap is consumable, and therefore should be
renewed every two to three years.
