• Do not replace oil with the engine in a tilted position.
• Filling with oil while engine is tilted leads to overfilling 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.
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 sufficiently
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 unleaded automobile gasoline 87 or higher octane ((R+M)/2). It may contain no more than
10% alcohol (E-10).
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
- 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 fill 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 flaw or damage on the tank cap, replace it.
• The tank cap wears out in course of time. Replace it every two to three years.
