BEFORE START OF OPERATION

Inspection and refill 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 insufficient (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 refill time is about 10h (every 10 refuellings). 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 16)

Recommended oil: SAE 10W-30 oil of API Classification, Class SF or higher (4-stroke engine for automobile)

Oil volume: Approx. 0.08L

Note: If the engine is not kept upright, oil may go into around the engine, and may be refilled excessively. If the oil is filled above the limit, the oil may be contaminated or may catch fire with white smoke.

Point 1 in Replacement of oil: “Oil cap”

Remove dust or dirt near the oil refill 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.

Keep the engine level, and detach the oil cap.
Fill with oil to upper limit mark. (see Fig. 3) Use oil bottle when filling.
Securely tighten the oil cap. Insufficient tightening may cause oil leakage.

Note

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 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.

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 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.

CORRECT HANDLING OF MACHINE

  If under idling conditions the tool should still continue to run, consult your nearest Authorized Service Agent.
Check the functioning of the I-O switch, the lock-off lever and the control lever.

REPLACEMENT OF ENGINE OIL

Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of replacement.

ATTENTION: In general, the engine main unit and engine oil still remain hot just after the engine is stopped. In replacement of oil, confirm that the engine main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of scald.

Note: If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.

The interval of replacement: Initially, every 20 operating hours, and subsequently every 50 operating hours

Recommended oil: SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)

In replacement, perform the following procedure.

Confirm that the fuel tank cap is tightened securely.
Place large container (pan, etc.) under drain hole.
Remove drain bolt and then remove oil cap to drain out oil from drain hole. At this time, be sure not to mislay drain bolt’s gasket, or to make dirty any of the removed components.
Once all the oil has been drained, combine gasket and drain bolt, and tightly secure drain bolt, so that it will not loosen and cause leaks.
Use cloth to fully wipe off any oil attached to bolt and equipment.
Alternative draining method
Remove oil cap, tilt Multi Function Power Head toward oil filler hole, and drain out oil.
Collect oil in container.
Set the engine level, and gradually fill up to upper limit mark with new oil.
After filling, tightly secure oil cap, so that it will not loosen and cause leaks. If oil cap is not tightly secured, it may leak.

POINTS ON OIL

Never discard replaced engine oil in garbage, earth or sewage ditch. Disposal of oil is regulated by law. In disposal, always follow the relevant laws and regulations. For any points remaining unknown, contact Authorized Service Agent.
Oil will deteriorate even when it is kept unused. Perform inspection and replacement at regular intervals (replace with new oil every 6 months).
