Makita_Water_Pump

Please make sure you review each precaution carefully.

SURROUNDINGS

m Operate the pump on a stable, level surface free of small rocks, loose gravel, etc.

m Keep pump at least 3feet (1 meter) away from buildings.

Keep pump away from flammables and other hazardous materials (trash, rags, lubricants,explosives).

FIRE PREVENTION

Be sure to stop the engine prior to refueling. m Do not overfill fuel tank.

mIf spillage does occur, wipe away spilt fuel thoroughly and wait until fuel has dried before starting engine.

m Do not operate while smoking or near an open flame.

EXHAUST PRECAUTION

Never inhale exhaust gasess; they contain carbon monoxide, a colorless, odorless, extremely dangerous gas which can cause unconsciousness or death.

mNever operate the pump indoors or in an enclosed area such as a cave or a tunnel.

Exercise extreme care when operating near people and domestic animals.

OTHER IMPORTANT POINTS

Keep away from rotating parts and hot parts while the pump is running. m Never permit anyone to operate the pump without proper instructions.

Know how to stop the pump quickly and understand operation of all the controls.

Tighten the fuel tank cap securely and close the fuel cock before transit.

Never operate the engine with gasoline only.

mCarefully check fuel pipes and joints for looseness and fuel leakage.

3. PREPARATIONS FOR STARTING

1. Connect the suction hose.

Use a reinforced-wallor wire braided hose to prevent suction collapse. Since the pump???s self-priming time is directly proportional to hose length, a short hose is recommended.

CAUTION][-

=Always use a strainer with the suc- tion hose. Gravel or debris sucked into the pump will cause serious damage to the impeller and the pump casing.

2. Connect the discharge hose.

When using a fabric hose, always use a hose band to prevent the hose from disconnecting under high pressure.

3. Check the fuel level.

If level is low, fill to the shoulder of the fuel filter.

Use the mixture fuel prepared by mixing gasoline and exclusive 2-cycle oil at a ratio of 20-25: 1, or the 2-cycle fuel now available on the market.

1 Oil

20 to 25

Gasoline

CAUTION}

For break-in of a new engine

Use mixture fuel of gasoline 15-20:2-cycle engine oil 1 during first 20 hours of operation.

4. Check the prlmingwater.

It is recommended that the water chamber of pump casing should be primed with full of water before operating.

+CAUTION],-

Never attempt to operate the pump without priming water or the pump

will overheat. Extended dry opera- tion will destroy the mechanical seal. If the unit has been operated dry, stop the engine immediately and al- low the pump to cool before adding priming water.

4. STARTING 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 half-way,or keep it open fully.

If the engine is cold, or the ambient

temperature is low, close the choke lever.

4.Pull the starter handle slowly until re- sistance is felt. This is the "compression" point. Return the handle to its original

positionand pull swiftly.

H Do not pull out the rope all the way.

HAfter starting the engine, allow the

starter handle return to its original positionwhile still holding the handle.

5. OPERATION

1.After starting the engine, gradually open choke by turning the choke lever and finally keep it open fully.

Do not fully open the choke lever im- mediately when the engine is cold or the ambient temperature is low, be- cause 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 to- ward the high speed position (H) and set it at the required engine speed.

NOTE :

Whenever high speed operation is not re- quired, slow the engine down (idle), by mov- ing the speed control lever to save fuel and extend engine life.

Avoid operating the engine at high speed for a long time without load.

- 7 -

6. STOPPING 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.

NOTE :

The above operation is necessary to prevent outside moist air from intruding into the combustion chamber.

STOPPING ENGINE WITH THE

FUEL COCK

Close the fuel cock and wait for a while until the engine stops.

Avoid letting fuel remain in the carburetor long period, or the passages of the carbu- retor may become clogged with impurities, and malfunctions may result.

DAILY INSPECTION

Before running the pump, check the following service items: a Enoughfuel.

a Excessivevibration, noise. a Clean air cleaner element. Safe surroundings.

Leakage of gasoline.

a Loose or broken bolts and nuts. m Check the priming water.

PERIODIC INSPECTION

Periodic maintenanceis vital to the safe and efficient operation of your pump. Check the table below for periodic maintenanceintervals.

The following chart is based on the normal pump operation schedule.

[CAUTION]

aReplace rubber pipes for fuel passage every two years. If fuel leakage is found, replace the pipe immediately.

0. "HOW-TO"MAINTENANCE

INSPECTING THE SPARK PLUG

Clean off carbon deposits on the plug electrode using a plug cleaner or wire brush.

w Check electrode gap.

(0.02to 0.03 in.)

CLEANING AIR CLEANER

Remove the element and clean it with kero-

sene. Then soak it in a mixture of 3 partsELEMENT kerosene and 1 part engine oil, squeeze out

the excess and install the elenent.

CLEANING MUFFLER

If solid carbon deposits to the exhaust port of cylinder or both inlet and outlet of the muffler to reduce these holes, it may cause a low output. In such a case, remove carbon deposit after detaching the muffler.

However, particularly by careful not to damage the piston and cylinder or not to allow ingress of carbon into the crankcase.

FUEL PIPE REPLACEMENT

Replace the fuel pipe every 2 years.

Iffuel leakage is found, replace it immediately.

- 10 -

CHECKING BOLTS, NUTSAND SCREWS

Retighten loose bolts and nuts.

Check for fuel and oil leaks.

Replace damaged parts with new ones.

Keep safety on your mind.

CLEANING FUEL STRAINER

wLoosen the banjo bolt from the carburetor and remove the strainer (plastic mesh).

wClean the strainer with kerosene and reassemble it.

WHEN ENGINE DOES NOT START:

fore you take the pump to your Makita dealer.

If you still have trouble after com- pleting the checks, take the pump to your nearest Makita dealer.

Before testing, carefully wipe off spilled fuel.

Put the plug as far away from the spark plug hole as possible. Ground the side of the electrode to any engine ground.

Is there a strong spark

enough com- failure I pression?

1Isplugthewetsparkwith- fuel?

r 1. Remove the plug and connect it to the plug cap. Pull the starter- handle while putting the plug against the engine ground.

t2. Try with a new plug if the spark is weak or no spark flies.

3.The ignition system is faulty if there is no spark with a new plug.

Take your pump to your nearest Robin dealer.

r1. Pull the starter handle slowly and check if resistance is felt.

2.If little force is required to pull the starter handle, check if the spark plug is tightened firmly.

3.If the spark plug is loose, tighten it.

4.if compression is still low, consult your nearest dealer.

-1. 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.

-2. When the electrode is dry, check where the fuel stops. (Check the fuel intake of the carburetor

-and fuel strainer intake.)

3.In case the engine does not start with well supplied fuel, try using different fuel.

IO . PREPARATIONS FOR STORAGE

mRemove 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 tighten the spark plug.

Slowly pull the recoil starter knob until resistance is felt and leave it in that posi- tion.

Store the pump in a dry place free from

sand or dust.

Always keep the pump covered.
