Suction hose
(not bent hose)
Holes
on hole
Confirm installing packing!
Ensure pump is fully filled up with water.
1
Ensure strainer at the end of suction hose is in water.
(If any mud or sand is at the bottom of water, suspend hose avoiding the bottom.)
2
Ensure no obstacle is at delivery hose side.
3
Make sure suction hose is connected properly
In case of no self-priming after filling pump with water and engine is started,
check suction hose connection carefully again.
Most cases of no self-priming are caused by improper hose connection.

4-stroke engine
4-stroke engine needs
"engine oil"
There is
no engine oil in the engine. Before starting engine, engine oil must be filled.
If you start engine without engine oil, engine will burn out and it is difficult to repair.
(Warranty does not cover such claim.)
Please use
"Non-Lead Gasoline for Automobile".
Inflammable!! Avoid fire when refuel or maintenance.
WARNING
Different accessories are suitable for different models.
Please check connection diameter and install correct parts.
CAUTION
CAUTION
Before starting engine, please check if engine oil is filled to required level.
Without engine oil or shortage of engine oil can cause troubles for engine.
Please read carefully Engine Operation Manual for engine oil instructions.
Inflammable! Do not operate near open fire.
Any fuel spillage must be cleaned completely.
Check engine oil before operation. Check and refuel periodically.
Please read Engine Operation Manual for instructions.
Stop engine operation when refuel engine oil.
Engine oil can be very hot after operation.
CAUTION
3 How to install Coupling
Coupling
Hose nipple
Coupling packing
Hose band
Fill pump with water before use
As pump is self-priming type, fill water fully from priming
port into pump before running. Insufficient water can cause
damage to pump.
5
Running without filling water can damage
mechanical seal.
CAUTION
Water inside may freeze at below 0˚C in
winter and may damage pump.
After use, drain water from drain plug
before storing.
CAUTION
Do not smoke as fuel is highly inflammable.
Unused fuel must not remain in the tank for long term storage.
Unused fuel may cause future engine failure.
CAUTION
Priming port
Do not close delivery
valve abruptly
Collapse of delivery hose
Drain water after use.
1
Long storage
Discharge fuel in fuel tank and carburetor completely.
Unused fuel in tank (if kept more than 30 days) may
cause engine failure.
*Please refer Engine Operation Manual.
2
CAUTION
Use suction hose for suction side. Use couplings/hose band as
provided in accessory and attach hose properly.
Installation of strainer at the end of suction hose is necessary.
CAUTION
Drain
TROUBLESHOOTING GUIDE
Remove obstacle in impeller.
(Please don't remove impeller)
N O T E
In case of water leakage between engine and pump,
usually the cause is damaged mechanical seal.
Please ask shop for assistance and replace mechanical seal.
- New spark plug may be required, if engine cannot start even after you clean
plug or adjust gap of plug.
Confirm spark plug
if wet or stained.
Please clean plug with cloth if
spark plug is wet or stained.
Confirm gap between
spark plug.
Plug gap should be 0.6-0.7mm.
Adjust gap to be within this range.
HOW TO USE
ATTENTION AFTER USE
There are many different types of spark plugs. Please check
and select correct plugs according to Engine Operation Manual.
CAUTION
For check assistance and repair, please ask your nearest sales
store for after sales service.

SOLUTION
PROBLEM
Beware of water hammering
Do not allow any vehicle to run over
the delivery hose. Do not close the
delivery valve abruptly because
water-hammer may occur.
This may result in heavy damage to
the pump.
For engine manual and notes, please refer Engine Operation
Manual enclosed.
Please install coupling in order of :
If you install coupling packing not in
above order, air leakage may result,
affecting water suction efficiency.
Do not change pump diameter by
altering suction hose.
Whether suction or not
Check suction pipe.
In case of no suction or small delivery, the
cause is usually due to air leakage at
suction side.
In such case :
Remove suction hose
Start engine with water inside the pump.
Press the palm of your hand to cover
the suction hole and wait 30 seconds. If
you feel suction on your palm, the pump
is working fine but hose connection
needs correction.
Please check if rubber packing is
installed and if there is any hole on
suction hose.
