1. SAFETY INSTRUCTION

To ensure safe operation –

• Honda water pump is designed to give safe and dependable service if operated according to instructions.

Read and understand the Owner’s Manual before operating the water pump. Failure to do so could result in personal injury or equipment damage.

• Exhaust contains poisonous carbon monoxide, a colorless, odorless gas. Breathing carbon monoxide can cause loss of consciousness and may lead to death.

• If you run the pump in an area that is confined, or even partially enclosed area, the air you breathe could contain a dangerous amount of exhaust gas.

• Never run your pump inside a garage, house or near open windows or doors.

• Stop the engine before refueling.

• Gasoline is extremely flammable and explosive under certain conditions. Refuel in a well ventilated area with the engine stopped.

• The muffler becomes very hot during operation and remains hot for a while after stopping the engine. Be careful not to touch the muffler while it is hot. Let the engine cool before storing the water pump indoors.

• The engine exhaust system will be heated during operation and remain hot immediately after stopping the engine.

To prevent scalding, pay attention to the warning marks attached to the water pump.

To ensure safe operation –

• Never attempt to modify the water pump. It can cause an accident as well as damage to the water pump and appliances. Tampering with the engine voids the EU type-approval of this engine.

– Do not connect an extension to the muffler.

– Do not modify the intake system.

– Do not adjust the governor.

• Always make a pre-operation inspection (page 9) before you start the engine. You may prevent an accident or equipment damage.

• For safety, never pump flammable or corrosive liquids such as gasoline or acid. Also, to avoid pump corrosion, never pump sea water, chemical solutions, or caustic liquids such as used oil, wine, or milk.

• Place the pump on a firm, level surface. If the pump is tilted or overturned, fuel spillage may result.

• To prevent fire hazards and to provide adequate ventilation, keep the pump at least 1 meter (3 feet) away from building walls and other equipment during operation. Do not place flammable objects close to the pump.

• Children and pets must be kept away from the area of operation due to a possibility of burns from the hot engine components.

• Know how to stop the pump quickly, and understand the operation of all controls. Never permit anyone to operate the pump without proper instructions.

• Gasoline is extremely flammable and is explosive under certain conditions.

– Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the refueling area or where gasoline is stored.

– Do not overfill the tank (there should be no fuel above the upper limit mark). After refueling, make sure the tank cap is closed properly and securely.

• Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine.

• Never run the engine in an enclosed or confined area. Exhaust gas contains poisonous carbon monoxide gas; exposure can cause loss of consciousness and may lead to death.

• Before each use, look around and underneath the engine for signs of oil or gasoline leaks.

4. PRE-OPERATION FOR STARTING

Before each use, look around and underneath the engine for signs of oil or gasoline leaks.

1. Connect the suction hose.

Use commercially available hose, hose connector, and hose bands.

The suction hose must be of reinforced, noncollapsible construction.

Suction hose length should not be longer than necessary, as pump performance is best when the pump is not far above the water level.

Self-priming time is also proportional to hose length.

The strainer that is provided with the pump should be attached to the end of the suction hose with a band, as shown.

CAUTION:

Always install the strainer on the end of the suction hose before pumping.

The strainer will exclude debris that can cause clogging or impeller damage.

2. Connect the discharge hose.

Use a commercially available hose, hose connector, and hose band. A short, large-diameter hose is most efficient. Long or small-diameter hose increases fluid friction and reduces pump output.

NOTE:

Tighten the hose band securely to prevent the hose from disconnecting under high pressure.

3. Check the engine oil level.

CAUTION:

• Engine oil is a major factor affecting engine performance and service life. Nondetergent or vegetable oils are not recommended.

• Check the oil level with the pump on a level surface and the engine stopped.

Use 4-stroke motor oil that meets or exceeds the requirements for API service category SE or later (or equivalent). Always check the API service label on the oil container to be sure it includes the letters SE or later (or equivalent).

SAE 10W-30 is recommended for general use. Other viscosities shown in the chart may be used when the average temperature in your area is within the recommended range.

Lubrication oil specifications necessary to maintain the performance of the emissions control system: Honda genuine oil.

AMBIENT TEMPERATURE

Check the engine oil level with the engine stopped and in a level position.

1. Remove the oil filler cap.

2. Check the oil level. If it is below the upper limit, fill with the recommended oil (see page 10) to the upper limit.

3. Reinstall the oil filler cap securely.

CAUTION:

Running the engine with insufficient oil can cause serious engine damage.

Oil Alert System

The Oil Alert System is designed to prevent engine damage caused by an insufficient amount of oil in the crankcase. Before the oil level in the crankcase can fall below a safe limit, the Oil Alert System will automatically stop the engine (the ignition switch will remain in the

ON position).

If the engine stops and will not restart, check the engine oil level before troubleshooting in other areas.

11


4. Check the fuel level.

Use automotive unleaded gasoline with a Research Octane Number of

91 or higher (a Pump Octane Number of 86 or higher).

Fuel specification(s) necessary to maintain the performance of the emissions control system: E10 fuel referenced in EU regulation.

Never use gasoline that is stale, contaminated, or mixed with oil.

Avoid getting dirt or water in the fuel tank.

• Gasoline is extremely flammable and is explosive under certain conditions.

• Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the refueling area or where gasoline is stored.

• Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine.

• Avoid repeated or prolonged contact with skin or breathing of vapor.

KEEP OUT OF REACH OF CHILDREN.

With the engine stopped and on a level surface, remove the fuel tank cap and check the fuel level.

Refill the tank if the fuel level is low.

Do not fill the fuel tank completely. Fill tank to approximately 25 mm (1 inch) below the top of the fuel tank to allow for fuel expansion. If may be necessary to lower the fuel level depending on operating conditions.

After refueling, make sure the tank cap is closed properly and securely.

NOTE:

Gasoline spoils very quickly depending on factors such as light exposure, temperature and time.

In worst cases, gasoline can be contaminated within 30 days.

Using contaminated gasoline can seriously damage the engine

(clogged carburetor, stuck valve).

Such damage due to spoiled fuel is disallowed from coverage by the warranty.

To avoid this please strictly follow these recommendations:

• Only use specified gasoline (see page 12).

• Use fresh and clean gasoline.

• To slow deterioration, keep gasoline in a certified fuel container.

• If long storage (more than 30 days) is foreseen, drain fuel tank and carburetor (see page 28).

Gasolines containing alcohol

If you decide to use a gasoline containing alcohol (gasohol), be sure its octane rating is at least as high as that recommended by Honda.

There are two types of ‘‘gasohol’’: one containing ethanol, and the other containing methanol.

Do not use gasohol that contains more than 10% ethanol.

Do not use gasoline containing more than 5% methanol (methyl or wood alcohol) and that does not also contain co-solvents and corrosion inhibitors for methanol.

NOTE:

• Fuel system damage or engine performance problems resulting from the use of gasoline that contains more alcohol than recommended is not covered under the warranty.

• Before buying gasoline from an unfamiliar station, first determine if the gasoline contains alcohol, if it does, find out the type and percentage of alcohol used.

If you notice any undesirable operating symptoms while using a particular gasoline. Switch to a gasoline that you know contains less than the recommended amount of alcohol.

• High altitude operation

At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Performance will decrease, and fuel consumption will increase.

High altitude performance can be improved by specific modifications to the carburetor. If you always operate the pump at altitudes higher than 1,500 m (5,000 feet) above sea level, have your servicing dealer perform these carburetor modifications.

Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5 % for each 300 m (1,000 foot) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.

CAUTION:

Operation of the pump at an altitude lower than the carburetor is jetted for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture.

17


6. OPERATION

CAUTION:

Never use the pump for muddy water, rejected oil, wine, etc.

After starting the engine, move the throttle lever to the FAST position for self-priming, and check pump output.

Pump output is controlled by adjusting engine speed. Moving the throttle lever in the FAST direction will increase pump output, and moving the throttle lever in the SLOW direction will decrease pump output.

8. MAINTENANCE

Periodic inspection and adjustment of the pump are essential if high level performance is to be maintained. Regular maintenance will also help to extend service life. The required service intervals and the kind of maintenance to be performed are described in the table below.

Shut off the engine before performing any maintenance. If the engine must be run, make sure the area is well-ventilated. The exhaust contains poisonous carbon monoxide gas; exposure can cause loss of consciousness and may lead to death.

CAUTION:

• If the pump has been used with sea water, etc., clean it with fresh water immediately afterward to reduce corrosion or remove sediment.

• Use genuine Honda parts or their equivalent for maintenance or repair. Replacement parts which are not of equivalent quality may damage the pump.

22


2. Air cleaner service

A dirty air filter will restrict air flow to the carburetor, reducing engine performance. If you operate the pump in very dusty areas, clean the air filter more frequently than specified in the Maintenance Schedule

(see page 21).

Never use gasoline or low flash point solvents for cleaning. They are flammable and explosive under certain conditions.

CAUTION:

Never run the pump without the air cleaner. Rapid engine wear will result from contaminants such as dust and dirt being drawn into the engine.

1. Unscrew the wing nut, remove the air cleaner cover and remove the element. (see page 14)

2. Clean the air filter elements if they are to be reused.

Paper filter element:

Tap the air filter element several times on a hard surface to remove dirt, or blow compressed air [not exceeding 207 kPa (2.1 kgf/cm

2

,

30 psi)] through the air filter from the inside. Never try to brush off dirt; brushing will force dirt into the fibers. Replace the air filter if it is excessively dirty.

23


Form filter element:

Clean the air filter in warm soapy water, rinse, and allow to dry thoroughly. Or clean in nonflammable solvent and allow to dry.

Dip the air filter in clean engine oil, and then squeeze out all excess oil. The engine will smoke when started if too much oil is left in the foam.

4. Spark plug service

Recommended spark plug: BPR6ES(NGK)

To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.

1. Disconnect the spark plug cap and then remove the spark plug with the spark plug wrench.

If the engine has been running, the muffler will be very hot. Be careful not to touch the muffler.

SPARK PLUG CAP

2. Visually inspect the spark plug. Discard the spark plug if there is apparent wear, or if the insulator is cracked or chipped. Clean the spark plug with a wire brush if it is to be reused.

3. Measure the plug gap with a suitable gauge.

Correct as necessary by bending the side electrode.

The gap should be:

0.7—0.8 mm (0.028—0.031 in)

0.7—0.8 mm

(0.028—0.031
