• Never allow the pump to run dry of the fluid
being dispensed. A dry pump will quickly accel-
erate to a high speed, causing damage to the
pump. If the pump accelerates quickly or is run-
ning too fast, stop it immediately and check the
fluid supply. If the supply container is empty
and air has entered the system, prime the
pump with fluid.
• The minimum flow rate generated by the pump
is 1.5 gpm (5.7 lpm). A new pump breaks in
over a period of time dependent on the level of
use. When the pump is completely broken in,
the flow rate generated by the pump may
increase to 1.6 - 1.7 gpm (6.1 - 6.4 lpm).
