• Check the equipment for loose screw or loose connec- tion parts before starting engine.

• Avoid touching the engine and muffler with any part of your body or clothing during inspection or repair, while they are still hot.

• Take special care of ventilation. Beware of CO poison- ing. INSPECTION AND REFILL OF ENGINE OIL (Fig. 4) Perform the following procedure, with the engine cooled down. – Assure that the engine is on horizontal position. – Do not thread the oil gauge into oil filler to check oil level. – Check if the oil level is between the lower or upper limit on the oil gauge. – If the oil level is below the lower limit, add oil. – You may need to refill oil approximately every 10 operating hours (every 10 refueling). – If the oil changes in color or mixes with dirt, replace it with new one. Recommended oil: SAE 10W-30 oil of API Classifica- tion, Class SF or higher (4-stroke engine for automobile) Oil volume: For model EW1050H: Approx. 0.08L For model EW1060H: Approx. 0.1L NOTE:

• If the engine is not positioned horizontal, an inaccurate indication of oil level may occur and oil may be over- filled. Filling oil above the upper limit may cause oil contamination or white smoke. Refilling engine oil

1. Keep the engine in horizontal position, and detach the

2. Fill with oil to upper limit mark. Use oil bottle when fill-

3. Securely tighten the oil gauge. Insufficient tightening

may cause oil leakage. After refilling oil – Wipe any spilled oil with a rag immediately. Replacement of oil: Oil gauge – Remove dust or dirt near the oil refill port. – Keep the detached oil gauge free from sand or dust. Otherwise, any sand or dust adhering to the oil cap may result in problems with irregular oil circulation or wear on the engine parts. FUEL

• Fuel is highly flammable and poisonous. Keep away from open flames (cigarette, stove, fireworks), electric spark (battery, short circuit, spark from shorted switch, welding spark etc.) when handling the fuel.

• Be sure to stop the engine before refueling. Do not refuel when the engine is still hot.

• Other than the occasion of refueling, even when decanting fuel to small container, always pay ample attention.

• After refueling, securely tighten the fuel tank cap, and wipe out spilled fuel completely. 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 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 sunlight. – Never keep the fuel in a car. Type of 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). – Never use a gasoline mixture which contains engine oil. Otherwise, it will cause excessive carbon accumulation or mechanical troubles. Fuel tank capacity: For model EW1050H: 0.5L For model EW1060H: 0.65L Refueling (Fig. 5)

1. Keep the engine in horizontal position.

2. Loosen the fuel tank cap a little to release the tank

3. Detach the fuel tank cap, and refuel. DO NOT fill fuel

up to the top of the tank.

4. After refueling, securely tighten the fuel tank cap.

– Wipe the outside of the fuel tank cap to prevent debris from entering into the fuel tank. – If there is any flaw or damage on the fuel tank cap, replace it. – The fuel tank cap wears out in course of time. Replace it every two to three years. – DO NOT put fuel in the oil fill port.9 Priming water (Fig. 6) CAUTION:

• Do not start the pump without water in the pump case. Otherwise mechanical seal could be damaged. Remove priming plug and add clear water until pump case is filled up with water. After filling tighten the priming plug. NOTE:

• If the water intake is not sufficient, self-priming capacity becomes lower.

• Be sure the pump is placed on the firm place and as near to available water source as possible.

• The higher the suction head is the more time will be required for priming with a less discharge. CHECKING ENGINE: – Carefully check fuel hoses and joints for looseness and fuel leakage. Leaked fuel creates a potentially dangerous situation. – Check bolts and nuts for looseness. If any, retighten them. A loose bolt or nut may cause serious engine trouble. – Check the engine oil and refill if necessary. – Check the fuel level and refill if necessary. Take care not to overfill the tank. – Keep cylinder fins and recoil starter free of dirt, grass and other debris. – Wear snug fitting working clothes when operating the engine. OPERATION

• Never touch a hot engine muffler especially when restarting the engine. The engine muffler becomes hot after running the engine.

• Do not put your hands or foreign objects in the release valves when the pump is in use.

• Do not allow the wheel of a vehicle to run over the delivery hose. Do not close the delivery valve abruptly, because a water-hammer will occur which may result in heavy damage to the pump. Starting: CAUTION:

• Because the lubricating oil has not yet spread enough, do not rev up the engine just after engine starts. Unnecessary high-revolution shortens life of the equip- ment or cause damage.

1. Check that the pump case is filled with water.

2. Check that the strainer is set under the water.

• Employ some preventive method when the bottom of the water is covered with mud or sand.

3. Check there is no obstacle on the mouth of delivery

4. Turn the engine I-O (ON/OFF) switch to the “I” (ON)

5. Check that the throttle lever indicates “L”. (Fig. 7)

6. Continue to push the primer pump until fuel comes

– If the engine is cold or the ambient temperature is low, close the choke lever fully. (Fig. 8) – If the engine is warm or the ambient temperature is high, open the choke lever half-way, or keep it fully open.

8. Pull the starter knob gently until a certain resistance is

felt. Then, return the starter knob, and pull it strongly. Never pull the rope to the full extension. Once the starter knob is pulled, never release your hand immediately. Hold the starter knob until it returns to its original point. If it is difficult to start the engine, open the throttle by about 1/3.

9. Once engine starts, set choke lever to the OPEN

position if you have closed the choke lever. (Fig. 9) 10.Allow the engine to properly “warm up”. Continue warm-up operation for 2 to 3 minutes at “L” position. Running engine: Turn the throttle lever to middle position, and check water come out from the delivery hose. Finishing operation Stopping engine Turn the throttle lever to “L” position to set the engine at the lowest revolution. Turn the engine I-O (ON/OFF) switch to the “O” (OFF) position. Drain of water after use Water inside the pump case freezes at below 0°C in winter and pump may possibly break. After use, drain water from the drain at bottom to store. SERVICING INSTRUCTIONS

• Before doing any work on the equipment, always stop the engine. Do not perform any work when the engine is still hot. CAUTION:

• Do not modify or adjust the carburetor. It is already fac- tory adjusted for its best efficiency. In case adjustment is required, ask your local service center.

• Do not wash the engine with water during servicing.

• The engine and engine oil is still hot just after stopping engine. Allow sufficient time for the engine and engine oil to cool down. Otherwise a skin burn may result. CAUTION:

• Before changing oil, check for a suitable way to dis- pose of old oil. Do not pour it down into sewage drains, onto garden soil or into open streams. Your local zon- ing or environmental regulations will give you more detailed instructions on proper disposal. Deteriorated engine oil shortens the life of the engine. Be sure to check the oil and level regularly. NOTE:

• If the oil filled above the limit, it may be contaminated or may catch fire with white smoke. Allow sufficient time after stopping engine for the engine oil to return to the oil tank to ensure accurate reading of the oil level.10 Interval of replacement: After first 20 operating hours, followed by every 50 operating hours. Recommended oil: SAE 10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile) Oil volume: For model EW1050H: Approx. 0.08L For model EW1060H: Approx. 0.1L

1. Remove the oil gauge. (Fig. 10)

Be cautious to place the oil gauge in a place where it will not gather dirt, dust or other foreign matter.

2. Place a cloth or paper towel to the area around the oil

3. Remove the oil gauge, then tilt the engine and drain

the oil into a pan or other receptacle.

4. Put the equipment on a level surface. Pour the oil in

from a squeeze bottle or other appropriate. Fill with the oil up to the point of overflowing the filler neck. (Fig. 4)

5. After filling the engine with oil, reinsert the oil gauge.

Ensure that the oil gauge is tight, as if it loosens later oil will leak out. CHECKING THE SPARK PLUG (Fig. 11) CAUTION:

• Never touch the spark plug connector while the engine is running (danger of high voltage electric shock). Interval of Cleaning and Inspection: Daily (every 10 operating hours) – Only use the supplied universal wrench to remove or to install the spark plug. – The gap between the two electrodes of the spark plug should be 0.7 – 0.8 mm. If the gap is too wide or too narrow, adjust it. If the spark plug is clogged or contaminated, clean it thoroughly or replace it. CLEANING OF AIR CLEANER (Fig. 12)

• Shut off the engine. Keep away from open flames. Dirty air cleaner element causes starting difficulty, power loss, engine malfunctions, and shortens engine life extremely. Keep the air cleaner element clean. Interval of Cleaning and Inspection: Daily (every 10 operating hours)

1. Place the choke lever to the fully closed position so

that dust and dirt are not allowed to enter the carbure- tor.

2. Remove the fixing bolt of air cleaner cover.

3. Pull out the lower edge of the cover to remove the air

4. Remove the element, and then clean it with a solution

of warm water and a mild detergent, thoroughly drying it afterward.

6. Wipe off any oil adhering to the area around the air

cleaner cover and breather with a cloth.

7. After cleaning, reassemble the cleaner cover (insert

• Shut off the engine. Keep away from open flames. Do not smoke. Interval of Cleaning and Inspection: Monthly (every 50 operating hours) The fuel filter is used to filter the fuel required by the car- buretor. A periodical visual inspection of the fuel filter is to be conducted.

1. Open the fuel tank cap, use a wire hook and pull out

the suction head through the tank opening.

2. Remove the hose clamp and pull out the fuel filter

3. Wash the fuel filter with kerosene.

4. After washing, reassemble it.

5. If the filter is hard or clogged up, replace it with new

one. Replace the fuel filter at least quarterly to ensure an enough fuel supply to the carburetor. Otherwise an insuf- ficient fuel supply may cause the engine start failure and limited maximum speed. After checking, cleaning or replacing, fix the fuel filter onto the fuel pipe with the hose clamp. Push the fuel filter in all the way to the bottom of the fuel tank. (Fig. 13) REPLACEMENT OF FUEL PIPE (Fig. 14)

• Shut off the engine. Keep away from open flames. Interval of Cleaning and Inspection: Daily (every 10 operating hours) Replacement: Annually (every 200 operating hours) Replace the fuel pipe every year, regardless of operating frequency. Fuel leakage may lead to fire. If any leakage is detected during inspection, replace the fuel pipe immediately.

INSPECTION OF BOLTS, NUTS AND SCREWS

– Retighten loose bolts, nuts, etc. – Check the fuel cap and oil cap for tightness. Check for fuel and oil leakage. – Replace damaged parts with new ones for safety operation.

– Always keep the 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 piston seizure.11 Periodic maintenance schedule table *1 Perform initial replacement after 20h operation. Before changing oil, check for a suitable way to dispose of old oil. Do not pour it down into sewage drains, onto gar- den soil or onto open streams. Your local zoning or environmental regulations will give you more detailed instruc- tions on proper disposal. *2 For the 200 operating hours inspection, request authorized service center. STORAGE

• When draining the fuel, be sure to stop the engine and confirm that the engine cools down. Just after stopping the engine, it may still hot with possibility of burns, inflammability and fire. CAUTION:
