Operation
Shut Down.
1.
For normal system shut down, disconnect power
to lubricator controller (J) by turning off the ignition
switch, and turn off hydraulic supply by closing the
ball valve (Fig. 2, item AA).
CAUTION
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging pump. If your pump
accelerates quickly, or is running too fast, stop the
pump immediately and check the fluid supply.
