OPERATION

1. Starting

1) When the engine is cold or after refuelling

(1) Set this machine on a flat space.
(2) Set the stop switch to “ I ” position (Figure 1).
(3) Continue to push the primer pump until fuel comes into the

primer pump (Figure 2).

• In general, fuel enters into the carburetor by 7 to 10 pushes.
• If the primer pump is pushed excessively, an excess of gas-

oline returns to the fuel tank.

(4) Lift the choke lever to the closed position (Figure 3).
(5) Hold the main handle with left hand to prevent the engine from

moving.

(6) Pull out slowly the starter handle till a certain resistance is felt.

Return the starter handle backward once from this position,
then pull it out with force (Figure 4).

• Never pull the rope to the full extension.
• Once the start knob is pulled, never release your hand

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

(7) When the engine starts, open the choke lever (Figure 5).

• Open the choke lever progressively while checking the

engine operation. Be sure to open the choke lever to the full
in the end.

• In cold or when the engine is cooled down, never open the

choke lever suddenly. Otherwise, the engine may stop.

(8) Continue warm-up operation for 2 to 3 minutes.
(9) Warm-up is complete when there is quick engine acceleration

from low rpm to full throttle.

WARNING

• Never attempt engine start in a place where the fuel has been supplied.

- If may cause ignition or fire. When starting the engine, keep a distance of at least 3 m.

• Exhaust gas from the engine is toxic. Do not operate the engine in a poorly-ventilated place, such as in a tunnel, building, etc.

- Operating the engine in the poorly-ventilated place may cause poisoning by exhaust gas.

• In case of detection of any abnormality in sound, odor, vibration after start, stop the engine immediately and carry out inspection.

- If the engine is operated without attending such abnormality, an accident may occur.

• Confirm that the engine stops when the stop switch is set to “O” position.
