Troubleshooting guide
For all problems that are not covered by this table, please contact your local C.E.T. Fire pumps dealer or C.E.T. direct.
Problem
Probable cause
Remedy
The engine won't
start
No fuel in the combustion
chamber
The fuel tank is empty
Fill the fuel tank
The electric starter doesn't
work
Not enough electrical power
Check the electrical connections, check if the battery is charged, if required charge the battery. Check the
engine manual for faulty electrical starter problems. Use the recoil starter.
Faulty engine
Refer to the troubleshooting guide of the engine owner's manual
The engine output is
low
Engine is overheating
Refer to the troubleshooting guide of the engine owner's manual
The engine won't speed up
The throttle control system
is malfunctioning
Reset, repair or change the throttle control system.
The engine seems to
speed up and down
Air pockets are created in
the suction hose
Air pockets in the suction
hose
Make sure the inlet hose is straight and doesn't have a sharp turn angle allowing the formation of an air
pocket.
Suction hose is not air tight
Make sure to have well understood and applied the priming protocol of the pump. Check for any possible
air leakage in the suction hose. Check the mechanical seal for leakage.
Faulty engine
Refer to the troubleshooting guide of the engine owner's manual
The engine works but
the priming system
doesn't seems to be
able to fill the pump.
(part 1/2)
The exhaust gas flow
going through the venturi
isn't high enough
The engine speed is too low
The throttle should be in the "fast" position while priming. For engine's speed problem, refer to "the
engine output is low" section.
The exhaust port isn't
completely closed.
Check if the exhaust port closing handle completely covers the outlet pipe. Clean up and flatten the
closing surface beneath the exhaust port closing handle.
The pump is not air tight
The primer sucks in ambient
air and thus can't take out
all the air from the suction
pipe
Make sure drain valve and discharge valve are closed. Verify the suction hose(s) and the gaskets are in
good conditions.
Verify the end of the suction hose is completely submerged by at least 12" (305mm) of water. When
pumping high volumes of water, sometimes a whirlpool is created by the suction. If so, make sure to
submerge the suction hose end by at least 24" (610mm).
The pump is too high
above the water source
The height of water to pull
up is above the priming
system capacity
The priming system is guaranteed up to 20' (6meters). Above this height it is highly suggested to reduce
the height difference.
