runs rough.
1. Engine ON/OFF switch in OFF
position.
2. Dirty air filter
3. Out of fuel.
4. Stale fuel.
5. Fuel switch in OFF position (if
equipped).
6. Low oil level (units with low oil
shutdown system).
7. Spark plug wire not connected to
plug.
8. Bad spark plug.
9. Choke position incorrect.
10. Water in fuel.
11. Excessively rich fuel mixture.
12. Impeller obstructed.
13. Dirty fuel filter.
1. Place Engine ON/OFF switch in ON
position.
2. Clean or replace air filter.
3. Fill fuel tank.
4. Replace with fresh fuel.
5. Place fuel switch in ON position.

9. Adjust choke position.
10. Drain fuel tank; replace with fresh
fuel.
11. Contact
IASD
.
12. Clean impeller.
13. Replace fuel filter.
Pump not
operating.
1. Air leak in suction hose.
2. Suction and/or discharge hoses
blocked.
3. End of suction hose not submerged.
4. Total head exceeds pump capacity.
1. Check suction hose and connections
for leaks. Tighten or repair.
2. Check hoses and strainer. Clear
obstructions.
3. Increase suction hose length or
move pump closer to supply.
4. Reduce total head or choose a
different pump for the task.
Weak
discharge
flow.
1. Air leakage (intake) at suction side.
2. Reduced engine power output.
3. Damaged mechanical seal.
4. Suction lift too high.
5. Suction hose too long, or hose
diameter too small.
6. Leaking discharge hose or
connection.
7. Damaged mechanical seal.*
8. Impeller obstructed.
9. Worn impeller.**
10. Engine throttle in SLOW position.
11. Inlet hose joint not tight.
1. Check suction hose and connections
for leaks. Tighten or repair.
2. Contact
IASD
.
3. Replace mechanical seal.
4. Lower suction lift.
5. Shorten suction hose, or increase
hose diameter.
6. Check discharge hose and
connection for leaks. Tighten or
repair.
7. Replace mechanical seal.
8. Clean impeller.
9. Replace impeller.
10. Increase throttle position.
11. Tighten inlet hose joint.
Pump does
not prime, or
priming takes
a long time.
1. Air leakage (intake) at suction side.
2. Insufficient priming chemical inside
pump casing.
3. Drain plug is loose.
4. Engine malfunction.
5. Damaged mechanical seal.
6. Incorrectly sized suction hose.
7. Suction hose is too long.
8. Excessive suction lift. ***
9. Inlet hose joint not tight.
1. Check suction hose and connections
for leaks. Tighten or repair.
2. Add priming chemical.
3. Tighten drain plug.
4. Contact
IASD
.
5. Replace mechanical seal.
6. Use correct suction hose.
7. Move pump closer to supply.
8. Correct suction head.
9. Tighten inlet hose joint.
Pump loses
prime.
1. Chemical level drops below the end
of the suction line.
1. Increase length of suction line or
move the pump closer to the supply
source.
