Safety instructions

Your safety and the safety of others are very important. We have provided important safety messages in this manual and on the water pump. Please read these messages  carefully.   safety message alerts you to potential hazards that could hurt. You or others. Each safety message is preceded by a safety alert symbol. Warning: In some cases, the engine is delivered without engine oil. Please add the correct amount of engine oil before using the machine.
Water Pump Safety

• Please read the manual carefully before using the gasoline water pump set.
• Before operating, perform the pre-operation inspection to make your operation on the water pump safer.
• For the sake of safety, be sure not to pump inflammable or corrosive liquids (such as gasoline or acid). Similarly, be sure not to pump corrosive such as sea- water, chemical solutions, or alkaline liquids (used engine oil, alcohols and honey).
• Locate the water pump on a firm and leveled ground. A sloped or overturned water pump may result in fuel spilled out
• Operate the water pump in a well-ventilated place without fire resources and keep the water pump at least one meter from other devices.
• Because touching hot parts of the engine may get severe burns when operating the water pump keep children and pets far away from the operating site.
• Master the method to quickly stop the water pump; learn manipulation control devices Using the water pump without following the instructions in the manual must be avoided.

Warning: Gasoline is extremely flammable and explosive in certain conditions.
Filling gasoline in a well-ventilated place with a stalled engine. In gasoline filling and storage sites, be sure there are no smoking and fire resources such as flame, fire spark, and so on.
Do not spill gasoline out of the tank. After filling, make sure to tighten the fuel tank cap.
When filling, avoid spilling gasoline out, for spilled gasoline and gasoline vapor is prone to ignite. Once gasoline is spilled out, make sure to wipe it up before the operation.
Do not run the engine in an enclosed room and poor-ventilated place, since exhaust emissions from the engine contain toxic carbon monoxide (CO), which may making people lose consciousness and even lead to death.

Technical Data

Pre-operation preparation
Connecting the water inlet pipe
Use a commercially available hose, hose joint, and clamp. The water inlet hose must be of continuous and be non-folded. The length of the hose should be as the same as or not more than that required. In this case, not far away from the surface of the water supply, the water pump will arrive its optimal performance. Self-suction time varies with the length of the water inlet hose with a hose clamp, as shown in the diagram below.
Caution: Before pumping, install the filter securely to the end of the water inlet hose. The filtrates any impurity, which may produce passage jam to damaged impellers.
Be sure to install the hose joint and clamp well so as to prevent air leaks and pumping performance drop; loose water inlet hose will decrease the water pump performance and self-suction ability.
Note: tighten the hose clamp to avoid falling off under high pressure.
Connecting the water outlet hose
Use a commercially available hose, hose joint and clamp. A short hose with a big diameter is the best. A long hose witha  small diameter will increase flowing resistance and decrease the power output of the water pump.
Engine oil and fuel check
Picture C: (1) Filler Cap/Dipstick (2) Upper Limit (3) Lower Limit Picture D: (1) Maximum Fuel Level
The quality of the engine oil is one of the key factors in deciding engine performance and service life. Not apply filthy engine oil or vegetable oil.
Be sure to checkthe  engine oil level with the engine stalled and stand vertically in level ground.
Use 4-stroke gasoline engine oil or engine oil equivalent in quality with SF, SG from API. Oil velocity varies with average temperature, so engine oil with proper velocity in accordance with your region temperature.
Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range.
a) Remove the oil filler cap/dipstick and wipe it clean,
b) Insert the filler cap/dipstick into the oil filler neck, but do not screw it in,
c) If the level is low, fill to the top of the oil filler neck with the recommended oil.
Notice: Running the engine with insufficient oil can cause serious engine damage.

1. Remove the filler cap and check the fuel level.
2. Refill the tank if the fuel level is low. Do not fill above the shoulder of the fuel strainer.

Warning: · 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 area where the engine id refueled or where gasoline is stored.
• Do not overfill the fuel when refueling. Spilled fuel or fuel vapour 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 vapour.

KEEP OUT OF REACH OF CHILDREN!
Use unleaded gasoline with a pump octane rating of 95 or higher.
This engine is designed to operate on unleaded gasoline. Unleaded gasoline produces fewer engine and spark plug deposits and extends exhaust life.
Warning: Fuel can damage the paint and some types of plastic. Be careful not to spill fuel when filling your tank. Damage caused by spilling fuels not covered under warranty.
Never use stale or contaminated gasoline or oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.
Occasionally you may hear a light “spark knock” or “pinging” (metallic rapping noise) while operating under heavy loads. This in no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of gasoline. If spark knock or pinging persists, see an authorized water pump dealer.
Warning: Running the engine with persistent spark knock or pinging can cause engine damage.
Running the engine with persistent spark knock or pinging is misuse, and the Distributor’s Limited Warranty does not cover parts damaged by misuse.
Checking the air cleaner filter element check
Loosen the wing nut and remove the air cleaner cover.
Check the air cleaner element to be sure it is clean and in good condition. Clean or replace the element if necessary
Warning: Never run the engine without the air cleaner. Rapid engine wear will result from contaminants, such as dust and dirt being drawn into the engine.
Water capacity check in the pump
Before operating the pump, make sure to fill the pump with enough water.
CAUTION: Do not try to run the engine without water inside, otherwise the pump will become overheated. The prolonged running of the pump without water will damage the pump gasket. If the water in the pump is used up, stall the engine at once and fill the pump once it cools down.
Starting the engine
Picture E: (3) High (4) Low

1. Turn the fuel valve ON.

2. Close the choke lever.
   Do not use the choke if the engine is warm or the ambient temperature is high.

3. Turn the engine switch to the ON position.

4. Move the throttle lever downward slightly, just past the idle position.

5. Pull the starter grip lightly until resistance is felt, then pull it briskly.
   Warning: Do not allow the starter grip to snap back against the engine. Return it slowly to prevent damage to the starter.

Starting up in plateau regions
In plateaus or regions with high altitudes, a standard carburetor produces an over-dense combination of fuel air, resulting in decreased engine performance and increased fuel consumption. To keep the engine with high performance, install a carburetor main spray nozzle and readjust the adjusting screw for idle speed.
Using in plateau regions frequently with an altitude of over 1800m contact your dealer for replace the carburetor and make adjustments in advance. Even though a proper carburetor spray nozzle is installed in the engine, the power output of the engine will drop about 3.5% with every 305mmis increase in alti- Tue. If carburetor replacement and adjustment are not done, the “plateau- effect” will be more severe than that done.

Operation

Using the water pump in regions with a lower altitude than the carburetor spray nozzle is applicable, the engine performance will decrease and become overheated, and over- thin combination of fuel and air produced may cause severe damage of the engine.

1. Start and warm up the engine, and then open the choke gradually.
2. Set the throttle valve in accordance with the specified rational speed.

Stopping the engine
In case of emergency:
To stop the engine in an emergency, turn the engine switch to the OFF position. In normal use:

1. Move the throttle lever to the SLOW position
2. Turn the engine switch to the OFF position
3. Turn the fuel valve OFF.

Maintenance

To keep the water pump at optimal performance, checking and adjustment on it periodically is necessary.
Regular maintenance and service may extend its service life obviously. The Maintenance Schedule below specifies how often you should have your water pump served, and what things need attention.
Warning: Before maintenance and service, stall the engine. If maintaining when the engine runs, make sure to perform any check in a well-ventilated area.
Exhaust emissions from the engine contain toxic carbon monoxide (CO), which may cause loss of consciousness and even life.
Caution: If the water pump is applied to pump sea water, please pump freshwater immediately! Instead after pumping seawater so as to diminish sign of corrosion and to make away seawater deposits.
Changing the engine oil
Drain the oil while the engine is still warm to assure rapid and complete draining.

1. Remove the oil filler cap/ dipstick and drain plug to drain the oil.
2. Reinstall the drain plug and tighten it securely.
3. Refill with the recommended oil to the specified level

Engine oil tank capacity: 0.35Littres
Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take it in a sealed container to your local recycling center or service station for reclamation. Do not throw it in the trash or pour it on the ground.
Air Cleaner maintenance instructions
A dirty air cleaner will restrict airflow to the carburetor. To prevent carburetor malfunction, service the air cleaner regularly. Service more frequently when operating the pump in extremely dusty areas.
Warning: Never use gasoline or low flash point solvents for cleaning the air cleaner element. A fire or explosion could result.
Never run the engine 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 foam element.
2. Wash the element in a solution of household detergent and warm water, then rinse thoroughly, or wash in non-flammable or high flash point solvent. Allow the element to dry thoroughly.
3. Soak the element in dean engine oil and squeeze out the excess oil. The engine will smoke during initial start-up if too much oil is left in the element.
4. Reinstall the air cleaner element and the cover.

Spark plug maintenance instructions
In order to service the spark plug, you will need a spark plug wrench (commercially available).
Recommended spark plug: F7TC/F7RTC
To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
Warning: If the engine has been running, the muffler will be very hot. Be careful not to touch the muffler.

1. Remove the spark plug cap.
2. Clean any dirt from around the spark plug base.
3. Use a spark plug wrench to remove the spark plug.
4. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. Clean the spark plug with a wire brush if it is to be reused.
5. Measure the plug gap with a feeler gauge. Correct as necessary by carefully bending the side electrode. The gap should be: (0.70-0.80mm)
6. Check that the spark plug washer is in good condition, and thread the spark plug in by hand to prevent cross-threading.

After the spark plug is seated, tighten with a spark plug wrench to compress the washer.
If installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer. If reinstalling a used spark plug, tighten 1/8-1/4 turn after the spark plug seats to compress the washer.
Notice: The spark plug must be securely tightened.
An improperly tightened spark plug can become very hot and could damage the engine.
Never use spark plugs that have an improper heat range. Use only the recommended spark plugs or equivalent.

Transportation/storage

Warning: To avoid a fire, make sure to cool the water pump down thoroughly before transportation or storage in the room.
Transport the water pump with the fuel cock turned off, besides, keep it horizontal to prevent fuel from spilling. Spilled gasoline and gasoline vapor may ignite.

1. Make sure the storage site for the water pump is dry and clean.

2. Clean the water pump inside.
   If the water pump is used to pump water mud, sand or heavy debris, a deposit of such may remain inside it. Before storage, operate the water pump to suck into fresh water to wash, otherwise, the impeller may be damaged once reuse. After finishing washing, drive off the water drain plug, then empty the water in the pump thoroughly, and reinstall the water drain plug.

3. Empty fuel inside the fuel tank.
   a. Set the fuel cock to OFF, drive off the fuel drain plug of the carburetor floater room, and drain out the fuel in the carburetor. Hold drained gasoline in a proper container.
   b. Set the fuel cock to ON.
   c. Reinstall the fuel drain plug of the carburetor floater room.
   4. Replace engine oil.

4. Dismantle the spark plug, and fill clean specified engine oil into the cylinder about one soup spoon. Turn the engine several times to distribute oil evenly and then reinstall the spark plug.

5. Pull the starter handle until feels anti-action, and then continues pulling until the triangle mark on the starter wheel lines up with the starter screw hole. In this location, both the air inlet and exhaust valves are closed, which may prevent the engine inside from rusting.

6. Cover the water pump to protect it from dust.
