OPERATION
6. OPERATION
1) Safe Operating Precautions
To safely utilize the full potential of this pump, you need a complete understanding of its operation and a certain amount of practice with its controls.
Before operating the pump for the first time, please review the
"Safety Instruction" (refer to page 4) and the "PRE-OPERATION
INSPECTION".( refer to page 18)
Exhaust contains poisonous carbon monoxide gas that can build up to dangerous levels in closed areas. Breathing carbon monoxide can cause unconsciousness or death.
2) Pump Placement
For best pump performance, place the pump near the water level, and use hoses that are no longer than necessary. That will enable the pump to produce the greatest output with the least self-priming time.
As head increases, pump output decreases, The length, type and size of the suction and discharge hoses can also significantly affect pump output.
Minimizing suction head (placing the pump near the water level) is also very important for reducing self-priming time.

3) Suction Hose Installation
Use the commercially available hose and hose connector, and the hose clamp provided with the pump to install the suction, and tighten the clamp. Firmly fix the suction hose without moving.

2" water pump 50 mm
3" water pump 80 mm
4" water pump 100 mm
Use a hose clamp to securely fasten the hose connector to the suction in order to prevent air and water leakage. Check to ensure that the hose connector sealing washer is in a good condition.
Install the strainer (provided with the pump) on the other end of the suction hose and secure it with a hose clamp. The strainer will help prevent the pump from becoming clogged or damaged by debris.
4) Discharge Hose Installation
Use the commercially available hose and hose connector, and the hose clamp provided with the pump to install the discharge, and tighten the clamp. Firmly fix the discharge hose without moving.

OPERATION
It is best to use a short, large-diameter hose, because that will reduce fluid friction and improve pump's output.
Tighten the hose clamp securely to prevent the discharge hose from disconnecting under a high pressure.
5) Priming The Pump
Before starting the engine, make sure to fill the pump with water: screw off the priming plug and prime the pump fully with clean water.
Don't screw off the priming plug during operation of the pump to avoid damaging the equipment and injuring persons. Reinstall the priming plug and tighten it securely after priming.
Dry operating of the pump will destroy the pump seal. If the pump has been operated in a dry state, stop the engine immediately and allow the pump to cool before being primed.

OPERATION
6) High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Output power will decrease, and fuel consumption will increase. Air-fuel mixture will also be very likely to make the spark plug dirty and make starting difficult.
Engine performance can be improved by installing a main fuel jet of a smaller diameter in the carburetor and readjusting the pilot screw. If you always operate the water pump at altitudes higher than 1,000 m above sea level, have our company's authorized dealer perform this carburetor modification.
Even with a suitable carburetor, engine horsepower will decrease approximately by 3.5% for each 300 meter increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.
If a carburetor suitable to high altitude is equipped with an engine suitable to a lower altitude, the lean air fuel mixture will lead to lower engine output power, over-heating and serious damage.
