Ⅰ. General Safeguards

Safety Precautions

Before starting the engine, perform inspections according to the
procedures described on pre-operation inspections to avoid
accidents and damage to your machine.

For safety, never attempt using this GEP (gasoline engine
powered) water pump to deliver inflammable or corrosive liquids
(such as gasoline and acids). Likewise, corrosive mediums,
seawater, chemical solvents, alkaline liquids (such as used gasoline,
liquor and honey) should be avoided.

Place the water pump on a solid, level position surface to avoid
tilting or turnover that may give rise to spilling of fuel.

To prevent fire hazards, keep the pump well ventilated during
operation and maintain a distance of at least l meter between the
machine and the wall or other machines. Keep away from
inflammable substances.

Do not allow children and pets to enter the working area as this
may increase the chance of their getting burned by hot surfaces of
the operating parts.

Know how to stop the water pump quickly how to operate the
controls. Do not use the pump against the prescribed operating
rules.

WARNING：

Safety Precautions

The gasoline fuel is highly inflammable and may explode under

certain conditions.

Do the fueling with the engine shut down and in a well-ventilated

Please read this operation manual to have a
thorough understanding of the content there
before use the product. Failure to do so may
lead to personal injury or mechanical damage.

environment. No smoking is allowed and no open fire or sparks
allowed to exist in areas where fueling is carried out or the fuel is
stored.

Do not allow the fuel to overflow the fuel tank. Be sure to recap

the tank and tighten it after refueling.

When fueling, take care not to spill the gasoline about as the
gasoline vapor may easily get ignited to cause a fire hazard. Be sure
to remove the spilled gasoline as by wiping before starting the
engine.

Do not run the engine indoors or in a poorly ventilated space as
the exhaust gas produced by the running engine contains toxic
carbon monoxide that may cause the loss of personal
consciousness or even death.

Ⅲ. Operation before Starting Up

1. Connecting the water inlet
Connect the water inlet with a commercially available hose,
connector and fastener clip. The inlet hose must be a continuous
non-foldable structure with a length not more than required and
should be placed near to the source of water so as to achieve the
pump should be fitted to the end of the hose with the hose connector
as shown in the figure below.
CAUTION: Before pumping water, attach the filter to the end of the
hose to filter out foreign matters in the water, the presence of which
may cause clogging and damage to the wane wheel.
NOTE: The hose connector and fastener clip should be securely
fastened to prevent air leaks and reduction in suction power. A loose
hose will reduce the pump performance and self-suction capacity.

2. Connecting the water outlet
Connect the water outlet with a commercially available hose, hose
connector and fastener clip. Large diameter hoses are the most
effective while small ones will increase the flow resistance and
reduce the output power of the pump.

7

NOTE:

Be sure to the fastener clip is securely fastened to prevent the
outlet hose from coming off under high water pressure.

3.Checking the oil level

CAUTION:

·The oil is one of the major factors affecting engine performance
and life. Do not use dirty oil or vegetable oil.

·Be sure to check the oil level with the engine shut down and
placed on a level surface.

Please use the SE15-40, 4-stroke engine oil as recommended.
Please use the type of oil with a proper viscosity according to the

local average temperature.

Oil shortage alarm system (OSAS) (installation position)

The OSAS is designed to avoid damage of the engine due to the
shortage of oil in the crankcase. The system will automatically shut
down the engine just before the crankcase oil level drops down to
the minimum line of safety (with the engine switch staying in the ON
position).

If the engine is shut down and cannot be started again, check the
oil level before initiating further troubleshooting procedures.

Remove the oil dipstick and wipe it dry.

Insert the dipstick into the oil filler but not screw it in.

Replenish the crankcase with the recommended type of oil until

8

the oil level comes up to the upper most position of the refilled if the
existing oil level is found too low.

CAUTON:

·Running the engine at a low oil level will cause damage to it.

4. Checking the fuel level
Uncap the fuel tank and check the fuel level. Pouring gasoline if
the fuel level is found too low.
Please use the type of gasoline recommended by the Dealer
(Using the low lead content or lead-free gasoline type is good for
minimizing carbon deposits inside the combustion chamber).
Do not use a mixture of gasoline and oil or dirty gasoline to
prevent dirt, dust or water from entering the fuel tank.
CAUTION:

·The gasoline fuel is highly inflammable and may explode under
certain conditions.

·Do the fueling with the engine shut down and in a well-ventilated
environment. No smoking is allowed and no open fire or sparks
allowed to exist in areas where fueling is carried out or the fuel is
stored.

·Do not allow the fuel to overflow the fuel tank. Be sure to recap
the tank and tighten it after refueling.

9

·When fueling, take care not to spill the gasoline about as the
gasoline vapor may easily get ignited to cause a fire hazard. Be sure
to remove the spilled gasoline as by wiping before starting the
engine.

·Avoid frequent or extensive exposure of the skin to gasoline or
breathing in the gasoline vapor. Keep the gasoline out of the reach of
children.

·Fuel tank capacity: 1.0 gallons (US. 3.6 liters)

5. Checking the air cleaner filter element
Screw the wing nut and remove the washer and cleaner cover.

Check the filter element to see if it is too dirty and clean it if
necessary.

CAUTION:

Do not run the engine without the air cleaner as this may quicken
engine wear if dirt or dust is sucked into the engine through the
carburetor.

6. Checking and filling the pump with cooling water

The pump must be filled with water before it is put to operation.
CAU TION:

·Do not attempt running the pump without cooling water or the
pump will get overheated. Extensive running without cooling water
may also damage the air tightness of the pump. If the pump is found
running dry, stop the engine and pouring in water when it cools
down.

Ⅳ. Starting engine

1. Turn on the fuel tap (by setting it to the ON position).

2. Close the choke.
NOTE:

·The choke is not required when starting the engine warm or the
ambient temperature is rather high, (i.e. keep the choke open when
starting the engine).

3. Set the engine switch to the ON position.

4. Turn the throttle control lever slowly to the left.

12

5. Gently pull up the starter lever until a resistance is felt and then
quickly pull it up.
CAUTION:

·Do not allow the starter lever to retract quickly into the engine. Let
it go back gently to avoid damaging the starter.

Ⅴ.Use in Highland Areas

Operation in Highland Conditions
In highland areas (with a high ASL elevation), the air-fuel mixture

produced by a standard carburetor will be too thick and result in a
reduced engine performance and soared fuel consumption. For
operation in highland areas, the engine performance may be
increased by using a smaller diameter carburetor nozzle and
readjusting the carburetor idle speed. If the water pump is frequently
used in areas with a ASL elevation of more than 1800 meters (6000
feet), ask the local dealer to replace or readjust the carburetor
beforehand. Even if the engine is fitted with a carburetor nozzle of an
appropriate size, the engine power will still go down by about 3.5%
each time when the ASL elevation goes up by 305 meters (1000
feet). If no replacement or readjustment is ever made of the
carburetor, the highland effect of the engine output power will be
even more obvious.
CAUTION:
