Troubleshooting - red lion 6RLAG-2LST Owner's Manual

Problems
Pump will not pump
Pump will not prime
Priming takes a long time
a) Debris build-up
b) Faulty or semi-open valve(s)
c) Pipe or hose used is smaller than the thread sizes on the pump
Pump does not perform as well as
it should
Pump loses prime
Pump will not start
Pump starts, but runs roughly
Pump shuts down during operation
*1. Excessive suction lift must take into consideration:
a. Excessive suction lift must take into consideration:
b. Pipe Fitting
c. Elevation above sea level
Including all 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 several 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 or abrasives that this seal is not designed for.

TROUBLESHOOTING

Causes
Air leak in suction hose
The suction and/or discharge hose(s) may be blocked,
or the valve(s) are closed, faulty and/or blocked
The end of the suction hose is not submerged
Total head is too high for this pump to work against
Excessive suction lift (*1)
Suction hose is quite long
Air pockets or leaks in the suction hose
Flow is restricted due to:
Insufficient submergence of the end of suction hose
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 hose
Clogged impeller
Engine throttle is in SLOW position
Water level drops below the end of the suction hose
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
Choke is in the wrong position
Spark plug wire is loose
Faulty spark plug
Fuel is contaminated (water, debris, etc.)
Low oil level
No fuel
Low oil level
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 hoses and valves are in good working order
The end of the suction hose must be submerged
Reduce total head or use a higher head pump
Move the pump closer to liquid source
Refer to PUMP PLACEMENT section
Check the hose for loose connections
a) Clean the hoses 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 hose must be submerged
Replace impeller
Replace the seal
Check the hose for loose connections
Remove casing to clean out
Move throttle to FAST position
The end of the suction hose must be submerged
Add fuel per engine manufacturer's instructions
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 START 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
