Cleaning the fuel filter

CAUTION: Make sure there is no damage on the fuel tank. If there are any damage on the fuel tank, ask authorized service center immediately for repair.

NOTICE: Clean the fuel filter regularly. Clogged fuel filter may cause difficulty of start-up or failure of engine speed increase.

Check the fuel filter regularly as follows:

1. Fuel tank cap 2. Fuel filter 3. Hose clamp

2. Remove the fuel tank cap, drain the fuel to empty the tank. Check the tank inside for any foreign materials. If any, wipe clean such materials.

3. Pull out the fuel filter with wire through the fuel filling port.
4. If the fuel filter surface is contaminated, clean it with gasoline.

NOTICE: Follow the method specified by each local authority for disposing the gasoline used for cleaning the fuel filter.

NOTICE: Replace the fuel filter if it is excessively contaminated.

1. After checking, cleaning or replacing, insert the fuel filter into the fuel pipe and fix it with the hose clamp. Reset the fuel filter in the fuel tank and tighten firmly the fuel tank cap.

Adjustment of idling speed

CAUTION: The carburetor is factory adjusted. Never adjust other than idling speed. For other adjustments, ask your authorized service center.

Appropriate low-speed rotation is 2,800min^-1 (rpm). If it is necessary to change the rotation speed, adjust the idle speed with a Phillips screwdriver. If the engine stops or runs unsteadily at idle, turn the adjusting screw to the right, and the idling speed increases. If the machine blows too strong at idle, turn the adjusting screw to the left, and the idling speed drops.

1.Idling adjusting screw

Checking throttle valve

If the control cable is bent or caught, the throttle valve does not contact with the idle adjusting screw, and it prevents the engine from proper idling. In such a case, reposition the control cable to ensure proper valve movement.

If the throttle valve does not touch the throttle valve stopper even you pull the throttle trigger fully or if the throttle valve does not touch the idling adjusting screw while idling, turn the cable adjusting bolt as follows:

1. Loosen the fixing nut.
2. If the throttle valve does not touch the throttle valve stopper, turn the cable adjusting bolt counterclockwise.

If the throttle valve does not touch the idling adjusting screw, turn the cable adjusting bolt clockwise.

1. Cable adjusting bolt 2. Fixing nut

1. Tighten the fixing nut to fasten the cable adjusting bolt.
2. Check the movement of the throttle valve. The throttle valve comes to the position as illustrated when the throttle trigger/lever is pulled/turned.

Cleaning carburetor cover

If the carburetor cover gets dirty and it is difficult to check the throttle valve, clean the carburetor cover as follows:

NOTICE: Never use gasoline, benzine, thinner, alcohol or the like for cleaning the carburetor cover. Otherwise it may be tarnished.

1. Pass a slotted screwdriver through the hole on the engine cover. Release the clamp of the carburetor cover.

1. Carburetor cover

1. Clean the carburetor cover.

NOTICE: Use wet clean cloth for cleaning the carburetor cover.

1. Return the carburetor cover. Make sure the clamp of the carburetor cover clicks when it is set in place.

Inspecting bolts, nuts and screws and other parts

Retighten loose bolts, nuts, etc.

Check for fuel and oil leakage.

Replace damaged parts with new ones for safety operation.

Cleaning engine, cooling air inlet

Keep engine clean by wiping down with a cloth rag.

Keep the cylinder fins free of dust or dirt. Dust or dirt adhering to the fins may cause engine overheat and piston seizure.

Blowing air is taken in from the air inlet vent. When airflow drops down during operation, stop engine and inspect the air inlet vent for any blockages. Clean it if necessary. Such a blockage may cause overheat and damage the engine.

Replacing gaskets and packings

Replace gaskets and packings if the engine is disassembled.

Any maintenance of adjustment work that is not included and described in this manual is only to be performed by Authorized Service Agent.

Storage

WARNING: When draining the fuel, stop the engine and wait for the engine to cool down. Failure to do so may cause burns or fire.

CAUTION: When you store the machine for a long time, drain all fuel from the fuel tank and carburetor, and keep it at a dry and clean place.

Drain fuel from the fuel tank and carburetor before storing the machine as follows:

1. Remove the fuel tank cap, and drain fuel completely. If there is any foreign materials remaining in the fuel tank, remove it completely.
2. Pull out the fuel filter from the refill port using a wire.
3. Push the primer pump until fuel is drained from there, and drain fuel coming into the fuel tank.
4. Reset the filter to the fuel tank, and securely tighten the fuel tank cap.
5. Then, continue to operate the engine until it stops.
6. Remove the spark plug, and drip several drops of engine oil through the spark plug hole.
7. Gently pull the starter handle so that engine oil will spread over the engine, and attach the spark plug.
8. Keep the machine with its carry handle upside.
9. Keep the drained fuel in a special container in a well-ventilated shade.
