Hanger

BEFORE START OF OPERATION

Inspection and rell 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 insufcient (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 rell 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 20)

Recommended oil: SAE 10W-30 oil of API Classication, 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 relled 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 rell 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.

Oil cap

Internal stepped section (upper limit)

Oil pipe

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

(2) Fill with oil to upper limit mark. (see Fig. 3)

Use oil bottle when lling.

Internal stepped section (lower limit)

External mark (upper limit)

External mark (lower limit)

Fig. 2 Oil pipe Fig. 3

Top up with oil until oil level reaches internal stepped section (upper limit).

Oil

The area between the external upper and lower limits is transparent, so oil level can be checked externally against these marks.

(3) Securely tighten the oil cap. Insufcient 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 overlling 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.

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 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. Do not perform refuelling in the dusk or on unstable surface.

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.

POINTS IN OPERATION AND HOW TO STOP

CAUTION:

Observe the applicable accident prevention regulations!

NOTICE:

Remove the guide bar cover before starting the engine.

STARTING

Move at least 3 m away from the place of refuelling. Place the equipment on a clean piece of ground taking care that the attachment does not come into contact with the ground or any other objects.

A: Cold start

1) Set this machine on a ﬂat space.

2) Set the I-O switch (A) to OPERATION.

OPERATION

STOP

3) Primer pump Continue to push the primer pump (B) until fuel enters into the primer

pump. (In general, fuel enters into the primer pump by 7 to 10 pushes.) If the primer pump is pushed excessively, an excess of gasoline returns to

the fuel tank.

4) Recoil starter Pull the start knob gently until it is hard to pull (compression point). Then,

return the start knob, and pull it strongly. Never pull the rope to the full. Once the start knob is pulled, never release

your hand immediately. Hold the start knob until it returns to its original

point.

5) The handle equips with lock-off lever (C) to prevent accidental start. To

pull the throttle lever (D), grasp the handle to release the lock (the lock-off

button is pressed by hand pressure).

6) Warm-up operation Continue warm-up operation for 2 to 3 minutes.

Note: In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry the electrode

section of the spark plug.
