TROUBLESHOOTING
SOLUTION 1
Check suction pipe!
In case of no suction or small discharge,
the cause is usually due to air leakage at
suction side.
In such case :
1.Remove suction hose.
2.Start engine with water inside the pump.
3.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.
4.Please check if rubber packing is in-
stalled and if there is any hole on suc-
tion hose.
SOLUTION 2
A leak between the pump casing and the
engine is usually due to a damaged me-
chanical seal.
Refer to a local service center.
