1. The pump does<br />
not run when<br />
pressing the Start<br />
button.<br />
2. The pump<br />
only runs when<br />
pressing the start<br />
button.<br />
3. The pump does<br />
not run although<br />
all conditions<br />
appear correct.<br />
4. The pump runs<br />
continously after<br />
start although the<br />
outlet is closed<br />
5. The pump stops<br />
after working time<br />
and must be started<br />
manually.<br />
6. The pump<br />
makes a noise.<br />
7. The oil pump<br />
does not start after<br />
power failure.<br />
The current is<br />
interupted. Check<br />
the switches,<br />
fuses etc.<br />
The oil quantity<br />
in the pump is<br />
insufficent or the<br />
working float is out<br />
of function because<br />
of mechanical<br />
locking. Prime the<br />
pump until the motor<br />
starts or press<br />
the start button till<br />
the motor runs by<br />
itself.<br />
The motor buzzes<br />
but does not<br />
rotate - the pump<br />
is blocked. Turn<br />
motor axle with a<br />
coin or screwdriver.<br />
Exchange the<br />
pump and gasket<br />
if necessary.<br />
Exchange pump<br />
and rubber bushing.<br />
The consumption<br />
is bigger than the<br />
capacity of the<br />
pump.<br />
Air in the suction<br />
line. Probably a<br />
small leakage.<br />
The oil level too<br />
low. Press Start<br />
button till the motor<br />
runs by itself.<br />
The pump is filled<br />
with oil - wait for<br />
lowering of level.<br />
The connection<br />
pin to the float arm<br />
is broken.<br />
The pump is filled<br />
with oil - wait for<br />
lowering level.<br />
The suction line<br />
is leaking. Check<br />
all connections.<br />
Check with vacuum<br />
if necessary.<br />
Leakage on the<br />
outlet pipe.<br />
The suction lift is<br />
too high.<br />
The oil lifter has<br />
lost the oil because<br />
of a leaking<br />
non-return valve.<br />
Fault in switches.<br />
Exchange the<br />
switch system.<br />
Leakage at strainer.<br />
Check O-ring<br />
gasket.<br />
Leaking non-return<br />
valve.<br />
Pump defective.<br />
Exchange pump<br />
and rubber bushing.<br />
Leakage on outlet<br />
pipe.<br />
Motor fault. Exchange<br />
motor.<br />
The pump drive is<br />
broken.<br />
The suction lift is<br />
too high.<br />
