10. OPERATION AND USE
– 15 –
10.1 ‘PRIMING’ THE PUMP – FIG.9
− Position the pump on flat and firm surface.
− Before operating the pump, it should be ‘primed’
with water, which is added through the priming
hole
(2)
.
− Block off the outlet hose end of the pump so that
no water can drain out.
− Remove the screw-cap of the priming inlet
− Pour the water in through the priming hole slowly
and gradually until the water is overflowing from
the inlet hole.
10.2 SWITCHING ON
− The suction hose should be airtight, or air in the
hose will block the suction action of the liquid.
− The inlet of the suction hose should always be
submerged into the water in order to avoid
dry-running of the pump when the liquid level falls
(Fig.10).
− Make sure the suction hose does not lift up above
the pump, otherwise bubbles formed in the hose
might block the flow.
− Open any shut-off valves in the outlet hose
(injection nozzle, valves, etc.).
− Insert the battery pack.
− Start the pump by pressing the ON/OFF/pump
speed selection rocker switch
