valve is placed at the bottom of the barrel.

minute). If it does not, stop the pump and check that the
strainer is clean and hose is immersed in the fuel.
10. When the level indicator(1) shows the tank to be full, stop the

12. Replace the hose and the tank cap.
REMARK
The pump is protected by a fuse. If pump fails to function,
check fuse (15A).
Do not allow the pump to run dry, as this will overheat the motor. If
the barrel is emptied during the refuelling stop the pump immedi-
ately.
The maximum permitted running time for the pump is 30 minutes.
The tank should be full well within this time. Do not allow the
pump to run for longer than this as damage will occur to the
motor.
MAINTENANCE
Weekly: Clean the suction filter.
Monthly: Check hose joints, electrical cables and clean the pump
body of impurities.
Storage: If the pump is not to be used for a period, ensure that
fuel is sprayed into the motor housing every two weeks to prevent
risk of rusting to the rotor.
