①Coupling
Roll up the seal tape to attach the nipple or pipe to the suction or delivery sides.
Please fix coupling in order of :
If you do not fix coupling packing in above order, air leakage may occur,
affecting water suction efficiency.
Do not change pump diameter by altering suction hose.

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.
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.
5
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.
Running without filling water can damage mechanical seal.
If pump fails to draw water after filling up pump casing through the plug, it is likely due
to air leak caused by poor connection of suction hose. Check the connection of suction
hose and try again. See [ BEFORE USE ] "
Use the correct suction hose. Use attachment coupling and hose band and install
firmly. Make sure to attach the attachment strainer at the end of the suction hose.
