PROBLEMS
Pump will not pump Air leak in suction line.
The suction and/or discharge line(s) may be blocked, or the
valve(s) are closed, faulty and/or blocked.
The end of the suction line is not submerged.
Total head is too high for this pump to work against.
Pump will not prime excessive suction lift (*1).
Priming takes a Suction line is quite long.

flow is restricted due to:
perform as well as a) debris build-up.
it should b) faulty or semi-open valve(s).
c) Pipe or hose used is smaller than the thread sizes on the pump.
Insufficient submergence of the end of suction line.
excessively worn impeller (*2).
Seal is damaged (*3). liquid will be leaking through the middle
of the adapter.
Air pockets or leaks in the suction line.
Clogged impeller.
engine throttle is in SlOW position
Pump loses prime Water level drops below the end of the suction line.
Pump will not start No fuel.
faulty spark plug.
fuel valve lever is in the Off position
Ignition switch is in the Off position
Choke is in the wrong position.
Pump starts, but Choke is in the wrong position.
runs roughly
Spark plug wire is loose.
faulty spark plug.
fuel is contaminated (water, debris, etc.)
Pump shuts down No fuel.
during operation
*1) excessive suction lift must take into consideration:
a) Size and length of pipe
b) Pipe fitting
c) elevation above sea level
Including all of the above, we recommend that the total suction head not exceed 25 ft.
*2) An excessively worn impeller is mainly caused from cavitation, which is caused by a number of situations, such as:
a) Restricted suction
b) excessive suction lift
*3) The seal may be damaged due to:
a) Normal wear
b) Overheating
c) Pumping chemicals that this seal is not designed for.
Contact an authorized service depot for further assistance.

SOLUTIONS
Make sure suction hose is double clamped at joints, clamps are
tight, fittings have thread compound and are tight, with no nicks
or cuts in hose.
Check to see that the lines and valves are in good working order.
Increase its length, or move pump closer to source of liquid.
Reduce total head or use a higher head pump.
Move the pump closer to liquid source.
Refer to START-uP under OPeRATION.
Check the line for loose connections.
a) Clean the lines and fittings.
b) Check to see that the valves are in good working order.
c) Increase the size of hose or pipe to reduce friction losses.
The end of the suction line must be submerged.
Replace impeller.
Replace the seal.
Check suction line.
Remove casing to clean out.
Move throttle to fAST position
Increase length of suction line or move the pump closer to the
water source.
Allow engine to cool for 2 minutes, then fill fuel tank.
Replace spark plug.
Turn the fuel valve lever to the ON position.
Turn the ignition switch to the ON position.
Slide choke lever to the CHOKe position.
Slide choke lever to the RuN position.
Attach wire to spark plug securely.
Replace spark plug.
Allow engine to cool for 2 minutes, then drain fuel tank and
carburetor. fill tank with fresh fuel.
Allow engine to cool for 2 minutes, then fill fuel tank.
