check for rust or obstruction, do not over tighten the screws
when replacing the cover as this will jam the rotor against the
cover and also prevent the electric motor from turning and
blow the fuse.
Pump Wiring Overheating
This can happen when pump is operated in bypass mode for
longer than 3 minutes or if low voltage/amps. Ensure that
pump is not left running for longer than 3 minutes without
depressing Transfer Gun trigger.
The wiring loom has been extended using wire of insufficient
gauge. 25A wire is required and a matching connector
Pump makes a
squealing/scratching sound
while running.
This can be caused by dirt or debris entering the pump and
becoming caught in the working parts. Remove the end cover
of the pump by first unscrewing the three Socket Head screws
and lifting off the cover. Clean the impeller vanes ensuring you
remove any dirt particles caught between the ends of the
vanes and the impeller housing. Do not over-tighten head
screws when reassembling.
Pump stalls when Transfer
Gun trigger is released, and
pump is running.
The non-return valve in the outlet of the pump may be
jammed shut. Remove the outlet hose from the pump.
Operate the white plastic valve in the outlet port of the pump
manually (by pushing it in and out), to ensure it moves freely.
To Test & Repair if the Pump
is running but low or nil flow
from nozzle
Remove gun from hose & re-test, Run the hose into the tank
filling neck while checking.
If flow improves, check hole in the end of the nozzle for
blockage
Replace gun as required

pump
Check red alligator clip fitted to positive terminal, black to
negative. If it is the wrong way around the pump runs
backwards.
Check suction hose and foot filter are immersed in diesel. The
suction hose may be bent up out of the diesel.
If pump is brand new or has not been used in a long period of
time unscrew automatic gun from hose and put hose in filler
neck to prime pump
