PUMP SAFETY
Please make sure you review each precaution carefully.
SURROUNDINGS
H
H
H
Operate the pump on a stable, level surface free of small rocks, loose gravel,
etc.
Keep pump at least 3 feet (1 meter) away from buildings.
Keep pump away from flammables and other hazardous materials (trash,
rags, lubricants, explosives).
FIRE PREVENTION
m
H
H
H
Be sure to stop the engine prior to refueling.
Do not overfill fuel tank.
If spillage does occur, wipe away spilt fuel thoroughly and wait until fuel has
dried before starting engine.
Do not operate while smoking or near an open flame.
EXHAUST PRECAUTION
H
H
H
Never inhale exhaust gasess; they contain carbon monoxide, a colorless,
odorless, extremely dangerous gas which can cause unconsciousness or
death.
Never operate the pump indoors or in an enclosed area such as a cave or a
tunnel.
Exercise extreme care when operating near people and domestic animals.
OTHER IMPORTANT POINTS
H
H
H
H
H
Keep away from rotating parts and hot parts while the pump is running.
Never permit anyone to operate the pump without proper instructions.
Know how to stop the pump quickly and understand operation of all the
controls.
Tighten the fuel tank cap securely and close the fuel cock before transit.
Check the engine oil and refill if necessary.
Carefully check fuel pipes and joints for looseness and fuel leakage.

3. PREPARATIONS FOR STARTING
1. Connect the suction hose.
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.
tion hose. Gravel or debris sucked
into the pump will cause serious
2. Connect the discharge hose.
When using a fabric hose, always use a hose band to prevent the hose from
disconnecting under high pressure.
3. Check the engine oil level.
Engine oil is a major factor affecting engine performance and service life.
Nondetergent or vegetable oils are not recommended.
Use oil classified “SC” or higher grade.
If the oil level is below the fill level line on the dipstick, refill with the proper oil (see
table) to edge of the oil fuller neck.
Be sure to check the oil level on a level surface with the engine stopped.

4. Check the fuel level.
If level is low, fill to the shoulder of the fuel filter. Use fresh, clean automotive
gasoline.
5. Check the priming water.
It is recommended that the water chamber of
pump casing should be primed with full of
water before operating.

Never attempt to operate the pump
without priming water or the pump
will overheat. Extended dry operation will destroy the mechanical seal.
If the unit has been operated dry,
stop the engine immediately and allow the pump to cool before adding
priming water.

4. Pull the starter handle slowly until re-
sistance is felt. This is the "compression"
point. Return the handle to its original
position and pull swiftly.
Do not pull out the rope all the way.
I After starting the engine, allow the
starter handle return to its original
position while still holding the handle.

5. OPERATION
1. After starting the engine, gradually open choke by turning the choke lever and
finally keep it open fully.
H
Do not fully open the choke immediately when the engine is cold or the
ambient temperature is low, because the engine may stop.

2. After the engine starts, set the speed
control lever at the low speed position (L)
and warm it up without a load for a few
minutes.
Gradually move the speed control lever toward the high speed position (H) and set it at
the required engine speed.
NOTE :
Whenever high speed operation is not required, slow the engine down (idle), by moving the speed control lever to save fuel and
extend engine life.
Lock the control lever by
turning wing nut clockwise.

6. STOPPING THE ENGINE
1. Set the speed control lever to the low
speed position and allow the engine to
run at low speed for 2 or 3 minutes
before stopping.
2. Keep depressing the STOP B U T O N
until the engine stops.
Do not stop the engine suddenly when it
is running at high speed.
3. Close the fuel cock.
4.
Pull the starter handle slowly and return
the handle to its original position when
resistance is felt.
NOTE :
The above operation is necessary to prevent
outside moist air from intruding into the
combustion chamber.
STOPPING ENGINE WITH THE FUEL COCK
Close the fuel cock and wait for a while until the engine stops.
Avoid letting fuel remain in the carburetor long period, or the passages of the
carburetor may become clogged with impurities, and malfunctions may result.

DAILY INSPECTION
Before running the pump, check the following service items:
Enough fuel.
m Excessive vibration, noise.
Clean air cleaner element.
Safe surroundings.
Enough clean engine oil.
D Leakage of gasoline and engine oil.
Loose or broken bolts and nuts.
Check the priming water.

Make sure the fuel cap is tightly secured to avoid spillage.
When changing oil, stop the engine
and loosen the drain plug.
Tighten the drain plug before refilling.
Refer to the recommended oil table
on page 3.
Always use the proper grade and
clean oil. If the engine oil is contaminated, there is not enough or it is of
poor quality, engine life will be shortened.
CLEANING FUEL STRAINER
Check for water or contaminants in the fuel strainer.
To remove contaminants, close the fuel cock and remove the strainer cup.
After removing contaminants and water, wash the strainer cup with kerosene.
Reinstall it securely to prevent leakage.

SERVICING THE AIR CLEANER
Maintaining an air cleaner in proper condition
is very important. Dirt induced through improperly installed, improperly serviced or inadequate elements, wears out engines. Keep
the element always clean.
(a) Unlock the cover and remove the cleaner
element.
(b) Inner element:Wash the element with
kerosene, then soak it in mixed oil (Kerosene (3):Engine oil (1)).
Drain the mixed oil.
(c) Outer e1ernent:Wash the element with
kerosene, then dip it into the mixed oil
(Kerosene (3):Engine oil (1)).
Squeeze out the mixed oil. (Do not twist.)

Replace damaged parts with new ones.
CLEANING PUMP INSIDE
Turn the knob counterclockwise and open the casing cover holder.

OIL SENSOR (OPTION)
(a) The oil sensor detects the fall in oil level in
the crankcase and automatically stops the
engine when the oil level falls down below
the predetermined level.
(b) When engine has stopped automatically,
check the oil level. Refill engine oil to the
upper level and restart the engine.
(c) If the engine does not start by usual
starting procedures, check the oil level.
when refilling with oil. Remove oil
