FUEL/REFUELLING
BEFORE START OF OPERATION
Inspection and rell of engine oil
Perform the following procedure, with the engine cooled down. Set the engine level, remove oil cap (Fig. 1), and check to see whether or not there is oil in the range between the upper limit and lower limit marks of the oil pipe (Fig. 2).
Top up with oil to upper limit mark if oil is insufcient (oil level is close to lower limit mark) (Fig. 3). The area surrounding the external marks is transparent, so the amount of oil inside can be checked without having to remove the oil cap. However, if oil pipe becomes extremely dirty, visibility may be lost, and oil level will have to be checked against stepped section on inside of
oil pipe.
For reference, the oil rell time is about 10 h (10 times or 10 tanks of oil rell). If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P18)
Recommended oil: SAE 10W-30 oil of API Classication, Class SF or higher (4-stroke engine for automobile)
Oil volume: Approx. 0.08 L
NOTE: If the engine is not kept upright, oil may go into around the engine, and may be relled excessively.
If the oil is lled above the limit, the oil may be contaminated or may catch re with white smoke.
Point 1 in Replacement of oil: “Oil cap”
Remove dust or dirt near the oil rell port, and detach the oil cap. Keep the detached oil cap free of sand or dust. Otherwise, any sand or dust adhering to the oil cap may cause irregular oil circulation or wear on the engine parts, which will result in troubles.

Do not replace oil with the engine in a tilted position.•
Filling with oil while engine is tilted leads to overlling which causes oil contamination and/or white smoke.•
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 spilled oil before start of operation.
Note
REFUELLING
Handling of fuel
It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refuelling must be performed in a sufciently
ventilated room or in the open air. Never inhale fuel vapors, 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 comes 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 within a period of 4 weeks, even if it is kept in a special container in a well-ventilated and shaded area.
Otherwise, 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 a car. -
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 start-up. -
Refuelling
WARNING: INFLAMMABLES STRICTLY PROHIBITED
Gasoline used: Automobile gasoline (unleaded gasoline)
Loosen the tank cap a little to release the tank pressure. Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that the refuel port will be oriented upward. (DO NOT ll fuel up to the top of the tank.)
Wipe well the periphery of the tank cap to prevent foreign matter from entering the fuel tank. After refuelling, securely tighten the tank cap. -
If there is any aw or damage on the tank cap, replace it.•
The tank cap wears out in course of time. Replace it every two to three years.•

Cleaning the air cleaner
DANGER: Inammables strictly prohibited
Check and clean the air cleaner daily or every 10 operating hours.
Turn the choke lever fully to the close side, and keep the carburetor free from dust or dirt.
Loosen air cleaner cover mounting bolt. Remove the air cleaner cover. If oil adheres to the element (sponge), squeeze it rmly. If the elements are heavily contaminated: -
1) Remove the element (sponge), immerse it in warm water or in water diluted
neutral detergent, and dry it completely.
2) Clean the element (felt) with gasoline, and dry it completely.
Before attaching the elements, be sure to dry it completely. Insufcient drying of the element may lead to difcult startup.
Fit the element (sponge) into the element (felt). Fit the elements into the plate so that the sponge faces the air cleaner cover.
Wipe out oil adhering around the air cleaner cover and the breather part with waste cloth.
Immediately after cleaning is nished, attach the cleaner cover and tighten it with xing bolts. (In remounting, rst put the upper claw, and then the lower claw.)
