when resold.
1. SAFETY GENERAL RULES
Before operating, read the manual carefully and be sure to become familiar with it, otherwise
personal injury of death as well as severe parts damage may occur.
Before operating, perform the pre-operation inspection to make your operation on the
waterpump safer.
For the sake of safety, it is forbidden to pump inflammable or corrosive liquids (such as
gasoline or acid). Similarly, be sure not to pump corrosives such as seawater, chemical
solution, and alkaline liquids.
Locate the water pump on a firm and level ground. A sloped or over turned water pump may
result in fuel spilled out.
 Operate a water pump in a well-ventilated place without fire resources and keep it 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 quick stop the water pump; learn manipulating control devices. Using
the water pump without following the instructions in the manual is forbidden.
WARNING:
 Gasoline is extremely inflammable and explosive in certain conditions.
 Filling gasoline in a well-ventilated place with engine stalled. 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 fuel tank. After filling, make sure to tighten
the fuel filler 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 operation.

 Don’t run the engine in an enclosed room and poor-ventilated place, since
exhaust emission from the engine contain toxic carbon monoxide ( O),
which may make people lose consciousness, even lead to death.
2. PARTS DESCRIPTION
(Fig.1)
3. PRE-OPERATIO PREPARATIO
3.1 Connecting water inlet pipe
Use commercially available hose, hose joint and clamp. The water inlet hose must be of continuous
structure and be non-folded. The length of the hose should be as the same as or not more than that
required. The effect of suction is greater the shorter distance from the water surface.
Suction time varies with the length of the water inlet hose in direct ratio. The filter matching with the
water pump should be mounted to the end of the water inlet hose with a hose clamp.
(Fig.2)
AUTION:
 Before pumping, install the filter securely to the end of the water inlet hose. The
filter flits any impurity, which may produce passage jam to damage impellers.
 Be sure to install the hose joint and clamp well so as to prevent from air leaks
and pumping performance drop; loose water inlet hose will decrease the water
pump performance and self-suction ability.

3.2 Connecting t e water outlet ose
Use commercially available hose, hose joint and clamp. A short hose with a big diameter is the
best. A long hose with small diameter will increase flowing resistance and decrease the power output
of the water pump.
NOTE
Tighten the hose clamp to avoid falling off under high pressure.
3.3 Engine oil level c eck
AUTION:
 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 check engine oil level with the engine stalled and stand vertically in
level ground.
Use 4-stroke gasoline engine oil engine oil equivalent in quality with SF, SG from API. Oil velocity
varies with average temperature; please select engine oil with proper velocity according to your local
temperature.
ENGINE OIL ALARM SYSTEM
The engine oil alarm system is intended to avoid engine damage due to engine oil too low in the
crankcase.
(Fig.3)
Before the engine oil level in the crankcase drops down below the safety line, the alarm system will
turn off the engine automatically (while the engine switch keeps at O ).
If the engine stops and cannot restart, check the engine oil level first.
Remove the engine oil dipstick and wipe it clean;
Re-insert the dipstick into engine oil filler hole but not
screw it in, and then take it out to check the engine oil
level; if the engine oil level is too low, fill specified
engine oil up to the top of the filler hole.

moments to check its condition before you operate the pump. Be sure to take care of any problem you
find, or have your service dealer to correct it.
Make sure the pump is on a level surface and the engine switch is in the OFF position.
To prevent fire hazards, 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 engine.
Exhaust gas contains poisonous carbon monoxide. Avoid inhalation of exhaust gas. ever run the
engine in a closed garage or confined area.
AUTION:
Improperly maintaining this pump, or failing to correct a problem before
operation, could
cause a malfunction in which you could be seriously injured.
Always perform a preparation inspection before each operation, and correct any
problem.
4.1.1 Check the Condition of the Pump
Look for signs of damage.
Look around and underneath the pump for signs of oil or gasoline leaks.
Remove any excessive dirt or debris, especially around the engine muffler, and recoil
starter.
4.1.2 Check the Suction and discharge Hoses
Check the general condition of the hose. Be sure the hoses are in serviceable
condition before connecting them to the pump. Remember that the suction hose must
be reinforced construction to prevent hose collapse.
Check that the sealing washer in the suction hose connector is in good condition.
Check that the hose connectors and clamps are securely installed.
Check that the filter is in good condition and is installed on the suction hose.
4.1.3 Check the engine
Check the oil level. To avoid the inconvenience of an unexpected shutdown by the
engine oil alarm system, always check the engine oil level before startup.
Check the air cleaner. A dirty air cleaner will restrict air flow to the carburetor, reducing
engine and pump performance.
Check the fuel level. Starting with a full tank will help to eliminate or reduce operation
interruptions for refueling.
4.2 Starting t e Engine
4.2.1 Prime the pump.
4.2.2 Move the fuel cock to the ON position.
4.2.3 To start a cold engine, move the choke level to the CLOSED position. To restart a warm

a used one, twist 1/2-1/4 more turns.
AUTION:
Be sure to tighten the spark plug securely, otherwise it may become very hot and
possibly damage the engine. Never use a spark plug with improper heat range.
7. STARTING UP IN PLATEAU REGIONS
In plateau or regions with high altitude, standard carburetor produces over-dense combination
of fuel and 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 1380 m, contact
your dealer for replace the carburetor and make adjustment 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 1000 ft increase in altitude. If carburetor replacement and adjustment is not done,
the “plateau-effect” will be more severe.
AUTION:
Use the water pump in regions with lower altitude than that the carburetor spray
nozzle is applicable, the engine’s performance will be reduced and it would
overheated, and over-thin combination of fuel and air produce may cause severe
damage of the engine.
8. TRANSPORTATION/STORAGE
WARNING:
To avoid a fire, make sure to allow at least 20 minutes cooling the water pump
down before transportation or storage in 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.
8.1 Make sure the storage site for the water pump is dry and clean.
8.2 Clean the water pump inside.
If the water pump is used to pump water with mud, sand or heavy debris, deposit of such may
remain inside it. Before storage, operate the water pump to suck into fresh water to wash,
otherwise impeller may be damaged once reuse. Finishing wash, drive off the water drain plug,
then empty the water in the water pump thoroughly, and reinstall the water drain plug.
8.3 Empty the fuel tank.
