1. SAFETY INFORMATION

Read these labels before you operate the water pump.

To ensure safe operation-

For safety, never pump flammable or corrosive liquids such as gasoline or acid. Also, to avoid pump corrosion, never pump sea water, muddy 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 buildings and other equipment during operation. Do not place flammable objects close to the pump. A spark arrester is available as an optional part for this pump. It is illegal in some areas to operate an engine without a spark arrester. Check local laws and regulations before operating. Know how to stop the pump quickly, and understand the operation of all controls. Never permit anyone to operate the pump without proper instructions. Do not allow children to operate the pump. Keep children and pets away from the area of operation. Gasoline is extremely flammable and is explosive under certain conditions. Do not smoke or allow flames or sparks where the pump is refueled or where gasoline is stored. Refuel in a well-ventilated area with the engine stopped. Do not overfill the tank. Make sure that the filler cap is closed securely. Exhaust gas contains poisonous carbon monoxide. Avoid inhalation of exhaust gasses. Never run the pump in a closed garage or confined area. 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 pump indoors.

3. PRE-OPERATION CHECK

1. Suction hose (commercially available)

Use a reinforced-wall or 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. Secure the hose with the hose band.

1 IMPORTANT NoT’CE 1 Always install the strainer on the end of the suction hose before pumping. Graiel or debris sucked into the pump will cause serious impeller damage.

(optional parts)

2. Discharge hose (commercially available) 2. Discharge hose (commercially available)

STRAINER

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

NOTE: A short, large-diameter hose will provide lower fluid friction and improve efficiency.

3. Engine Oil

( IMPORTANT NOTICE 1 Running the engine with low oil level will cause

serious engine damage.

1. Place the water pump on a level serface.

2. Remove the oil filler cap/dipstick and wipe it clean.

3. Check the oil level by inserting the dipstick in the filler neck without screwing it in.

4. If the level is low, fill to the top of the oil filler neck with the recommended oil.

Use high-detergent, premium quality 4-stroke engine oil, certified to meet or exceed U.S. automobile manufacturer’s requirements for API Service Classification SG, SF/CC, CD.

( IMPORTANT NOTICE ] u

sing nondetergent oil or 2-stroke engine oil could

shorten the engine’s service life.

SAE 1 OW-30 ,is recommended for general, all-temperature use. Other viscosities shown in the following chart may be used when the average temperature in your area is within the indicated range.

4. Fuel

Unscrew the fuel filler cap. Check the fuel level.

FUEL TANK CAPACITY: WB20T...2.7 P (0.71 US gal, 0.59.lmp g,al)

WB30T...3.6 e (0.95 US gal, 0.79 Imp gal)

Gasoline is extremely flammable, and gasoline vapor can explode. Use extreme care when handling gasoline. Keep gasoline out of reach of children.

l Refuel in a well ventilated area with the engine stopped. Keep flames

and sparks away, and do not smoke in the area.

l Gasoline vapors or spilled gasoline may ignite. l Refuel carefully to avoid spilling gasoline. Avoid overfilling the fuel tank

(there should be no gas in the filler neck). After refueling, tighten the fuel cap securely. If any gasoline was spilled, make sure the area is dry before starting the engine.

l After use, store the water pump on a level surface. Be sure the storage

area is well ventilated; do not allow flames or sparks in the storage area.

After refueling, be sure to tighten the fuel filler cap firmly.

Gasoline Recommendation

Pump octane rating: 86 or higher We recommend unleaded gasoline because it produces fewer engine and

spark plug deposits and extends the exhaust system life.

If “spark knock” (metallic rapping noise) or persistent “pinging” occurs at a steady engine speed under normal load, change brands of gasoline. If spark knock or pinging persists, see an authorized Honda water pump dealer.

1 IMPORTANT NoTlCE 1 Running the engine with perisistent spark knock or pinging can cause engine damage.

Running the engine with persistent spark knock or pinging is considered

misuse, and the Distributor’s Limited Warranty does not cover parts

damaged by misuse.

Occasionally you, may hear light spark knock while operating under heavy

loads. This is no cause for concern. It simply means your engine is

operating efficiently.

Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid

getting dirt or water in the gas tank.

GASOLINES CONTAINING ALCOHOL

If you decide to use a gasoline containing alcohol (gasohol), be sure its oc-

tane rating is at least as high as that recommended by Honda (see

Gasoline Recommendation on page 9). There are two types of “gasohol”:

one containing ethanol, and the other containing methanol.

1 IMPORTANT NoTiCE I Using gasohol that contains more than 10% ethanol,

or gasoline containing methanol (methyl or wood alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol, can cause serious fuel system damage and poor engine performance.

Never use gasoline containing more than 5% methanol, even if it has cosolvents and corrosion inhibitors.

Honda cannot endorse the use of gasoline containing methanol since

evidence of its suitability is as yet incomplete.

NOTE: Fuel system damage or engine performance problems resulting from the use of gasoline that contains alcohol is not covered under the warranty.

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

NOTE: If you notice any undesirable operating symptoms while using a gasoline that contains alcohol, or one that you think contains alcohol, switch to a gasoline that you know does not contain alcohol.
