MAKITA EW200R (01) PDF SUMMARY:

What safety precautions should I take when using the pump?

Operate the pump on a stable, level surface that is free of small rocks and loose gravel. Keep the pump at least 3 feet (1 meter) away from buildings. Ensure the pump is away from flammables and other hazardous materials like trash, rags, lubricants, and explosives. Always stop the engine before refueling and avoid overfilling the fuel tank. If fuel spills, wipe it away and wait until it has dried before starting the engine. Refrain from smoking or operating the pump near an open flame. Never inhale exhaust gases, as they contain carbon monoxide, which can cause unconsciousness or death. Do not operate the pump indoors or in enclosed areas. Exercise caution when operating near people and animals. Keep away from rotating and hot parts while the pump is running. Ensure no one operates the pump without proper instructions. Know how to stop the pump quickly and understand all the controls. Securely tighten the fuel tank cap and close the fuel cock before moving the pump. Check and refill the engine oil if necessary. Carefully check fuel pipes and joints for looseness and fuel leakage.

How do I prepare the pump for starting?

1. Connect the suction hose, using a reinforced-wall or wire braided hose to prevent collapse. A short hose is recommended to minimize self-priming time. Always use a strainer with the suction hose to prevent gravel or debris from damaging the impeller and pump casing.
2. Connect the discharge hose, using a hose band to prevent disconnection under high pressure, especially when using a fabric hose.
3. Check the engine oil level. Use oil classified as “SC” or higher grade, avoiding non-detergent or vegetable oils. Refill with the proper oil to the edge of the oil filler neck if the level is below the fill line on the dipstick. Ensure the engine is stopped and the surface is level when checking.
4. Check the fuel level and fill to the shoulder of the fuel filter with fresh, clean automotive gasoline if low.
5. Check the priming water and prime the water chamber of the pump casing with water before operating. Never operate the pump without priming water to avoid overheating and destroying the mechanical seal. If the unit has been operated dry, stop the engine and allow the pump to cool before adding priming water.

How do I start the engine?

1. Open the fuel cock.
2. Set the speed control lever to “START”.
3. Close the choke lever. If the engine is warm or the ambient temperature is high, close the choke lever halfway or keep it fully open. If the engine is cold or the ambient temperature is low, close the choke lever.
4. Pull the starter handle slowly until resistance is felt (the “compression” point). Return the handle to its original position and pull swiftly. Do not pull the rope all the way out. After starting the engine, allow the starter handle to return to its original position while still holding the handle.

---

How do I operate the pump?

1. After starting the engine, gradually open the choke lever and keep it fully open. Do not fully open the choke lever immediately when the engine is cold or the ambient temperature is low, as the engine may stop.
2. After the engine starts, set the speed control lever at the low-speed position (L) and warm it up without a load for a few minutes. Gradually move the speed control lever toward the high-speed position (H) and set it at the required engine speed. Whenever high-speed operation is not required, slow the engine down (idle) to save fuel and extend engine life.

---

How do I stop the engine?

1. Set the speed control lever to the low-speed position and allow the engine to run at low speed for 2 or 3 minutes before stopping.
2. Keep depressing the STOP BUTTON until the engine stops. Do not stop the engine suddenly when it is running at high speed.
3. Close the fuel cock.
4. Pull the starter handle slowly and return the handle to its original position when resistance is felt. This prevents outside moist air from intruding into the combustion chamber.

---

How do I stop the engine using the fuel cock?

Close the fuel cock and wait for a while until the engine stops. Avoid letting fuel remain in the carburetor for a long period, as it may cause the carburetor to become clogged with impurities, resulting in malfunctions.

---

What daily inspections should I perform?

Before running the pump, check the fuel level, engine oil level, and priming water. Look for excessive vibration, noise, and leakage of gasoline and engine oil. Ensure the air cleaner element is clean and the surroundings are safe. Check for loose or broken bolts and nuts.

---

What periodic inspections should I perform?

Refer to the maintenance schedule for periodic maintenance intervals. The maintenance schedule is based on the normal pump operation schedule.

How do I inspect the spark plug?

Clean off carbon deposits on the plug electrode using a plug cleaner or wire brush. Check the electrode gap and adjust it to between 0.02 and 0.03 inches (0.6 and 0.7mm).

---

How often should I change the engine oil?

Change the engine oil initially after 20 hours of operation, and thereafter every 50 hours of operation.

---

What precautions should I take when changing the engine oil?

Make sure the fuel cap is tightly secured to avoid spillage. Stop the engine and loosen the drain plug when changing the oil. Tighten the drain plug before refilling. Refer to the recommended oil table on page 3. Always use the proper grade and clean oil. If the engine oil is contaminated, there is not enough, or it is of poor quality, engine life will be shortened.

---

How do I clean the fuel strainer?

Check for water or contaminants in the fuel strainer. To remove contaminants, close the fuel cock and remove the strainer cup. After removing contaminants and water, wash the strainer cup with kerosene and reinstall it securely to prevent leakage.

---

How do I service the air cleaner?

Maintaining an air cleaner in proper condition is very important. Dirt induced through improperly installed, improperly serviced, or inadequate elements wears out engines. Keep the element always clean.

1. Unlock the cover and remove the cleaner element.
2. For the inner element, wash it with kerosene, then soak it in mixed oil (Kerosene (3): Engine oil (1)). Drain the mixed oil.
3. For the outer element, wash it with kerosene, then dip it into the mixed oil (Kerosene (3): Engine oil (1)). Squeeze out the mixed oil (do not twist).

---

How often should I replace the fuel pipe?

Replace the fuel pipe every 2 years. If the fuel pipe is found leaking, replace it immediately.

---

How do I check the bolts, nuts, and screws?

Retighten loose bolts and nuts. Check for fuel and oil leaks. Replace damaged parts with new ones.

---

What should I do if the pump does not run or the pumping volume is small?

• Sticking of impeller: Disassemble and clean.
• Sucking air at the suction side: Check piping at the suction side.
• Drop in engine output: Consult your nearest dealer.
• Breakage of mechanical seal: Consult your nearest dealer.
• High suction lift: Lower.
• Suction hose is too long or thin: Use a thick hose in minimum length.
• Leak of water from the water passage: Stop leaking.
• Clogging of foreign substance in the impeller: Disassemble and clean.
• Wear of impeller.

---

What should I do if the pump does not self-prime?

• Strainer is clogged: Clean.
• Engine speed is too low: Consult your nearest dealer.
• Suction of air at suction side: Check piping at suction side.
• Insufficient priming water inside pump casing: Prime fully.
• Imperfect tightening of drain plug: Tighten the plugs completely.
• Engine speed is too low: Consult your nearest dealer.
• Sucking air from mechanical seal: Consult your nearest dealer.

What should I check when the engine does not start?

Perform the following checks before taking the pump to a Makita dealer.

1. Check for a strong spark across the electrode.
   • Remove the plug and connect it to the plug cap. Pull the starter handle while putting the plug against the engine ground.
   • Try with a new plug if the spark is weak or no spark flies.
   • If there is no spark with a new plug, the ignition system is faulty. Take your pump to your nearest dealer.
2. Check if the spark plug is wet with fuel.
   • Pull the starter handle slowly and check if resistance is felt.
   • If little force is required to pull the starter handle, check if the spark plug is tightened firmly.
   • If the spark plug is loose, tighten it.
   • If compression is still low, consult your nearest dealer.
   • Choke (close choke lever) and pull the starter handle five or six times.
   • Remove the plug and check if its electrode is wet. If the electrode is wet, fuel is well supplied to your engine.
   • When the electrode is dry, check where the fuel stops (check the fuel intake of the carburetor and fuel strainer intake).
   • In case the engine does not start with well-supplied fuel, try using different fuel.

---

What warning should I heed before testing the spark plug?

Before testing, carefully wipe off spilled fuel. If you still have trouble after completing the checks, take the pump to your nearest dealer. Put the plug as far away from the spark plug hole as possible and ground the side of the electrode to any engine ground.

---

How do I prepare the pump for storage?

1. Drain all water from the drain plug. When retightening the drain plug, be sure to clean the drain plug and the thread of casing to avoid damaging the thread.
2. Remove the strainer cup and open the strainer cock to discharge the fuel from the fuel tank. Remove the carburetor float chamber bolt from the bottom and discharge fuel from the carburetor (NO SMOKING!).
3. Change the used engine oil with fresh oil. Remove the spark plug, pour about 5 cc of engine oil into the cylinder, slowly pull the starter knob of the recoil starter 2 or 3 times, and lighten the spark plug.
4. Slowly pull the recoil starter knob until resistance is felt and leave it in that position.
5. Store the pump in a dry place free from sand or dust. Always keep the pump covered.

---

What are the oil sensor instructions?

(a) The oil sensor detects the fall in oil level in the crankcase and automatically stops the engine when the oil level falls below the predetermined level. (b) When the engine has stopped automatically, check the oil level. Refill engine oil to the upper level and restart the engine. © If the engine does not start by usual starting procedures, check the oil level.

---

What is the caution regarding the oil sensor?

Do not remove the OIL SENSOR PROBE when refilling with oil. Remove the oil filler cap on the opposite side of the carburetor.
